{"title":"Contacta","description":"\u003cp\u003eContacta is an assistive listening technology company that manufactures a range of solutions that provide clear communication, primarily designed to help those with hearing loss through hearing loop technology. For banks, credit unions, pharmacies, and businesses with teller windows or security barriers, Contacta's product solves a practical problem that gets overlooked in most security setups: clear communication between staff and customers when glass, barriers, or distance get in the way.\u003c\/p\u003e\n\u003cp\u003eThe products we carry at Safe \u0026amp; Vault Store focus on Contacta's Window Intercom Systems, also known as talk-through or speech transfer systems. These systems provide a microphone and speaker for both staff and customers to transmit speech from one side of the glass to the other, improving clarity and reducing the need for raised voices. Many of Contacta's standard kits include a built-in hearing loop that enhances communication for individuals using hearing devices, and operate hands-free for a more hygienic solution. This makes them an ideal complement to teller windows, vault access points, drive-through counters, pharmacies, and any environment where staff and customers communicate through a security barrier.\u003c\/p\u003e\n\u003cp\u003eContact's dealer network provides coverage throughout the United States and Canada, and the company provides design and technical support services. All Contacta systems are engineered to meet ADA accessibility standards for assistive listening, making them a practical investment for any business required to provide accessible communication for customers with hearing loss. \u003c\/p\u003e\n\u003cp\u003eHave questions about which Contacta system is right for your application?

Whether you're at a bank teller window, pharmacy counter, ticket booth, government office, or information center, this system ensures staff and customers can hear each other clearly, eliminating the need to shout through the glass or repeat oneself. It's the ideal solution for smooth, professional interactions while maintaining safety and privacy on both sides of the counter.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes everything you need for instant clarity: separate customer-side surface-mounted speaker (STS-S60) and omnidirectional microphone (STS-M54) modules, a staff microphone and speaker unit with dual mute, a high-performance amplifier, and an under-counter hearing loop for customers using hearing aids. With its durable mild-steel construction and sleek powder-coated finish, it's designed for heavy daily use in busy public environments. And because it's pre-engineered for plug-and-play setup, you can have it up and running quickly without complicated configuration.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-K002 uses advanced technology to ensure high-quality sound and reliable operation. The cardioid staff microphone and omnidirectional customer microphone capture speech clearly, while the precision-tuned amplifier delivers crystal-clear audio on both sides of the barrier. The integrated hearing loop makes it fully accessible, and the low-profile surface-mount design keeps the customer counter unobstructed for a clean sightline.

Whether you're at a bank teller window, pharmacy counter, ticket booth, government office, or information center, this system ensures staff and customers can hear each other clearly, eliminating the need to shout through the glass or repeat oneself. It's the ideal solution for smooth, professional interactions while maintaining safety and privacy on both sides of the counter.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes everything you need for instant clarity: flush-mounted customer speaker (STS-S61) and omnidirectional microphone (STS-M56) modules that install directly into the counter surface, a staff microphone and speaker unit with dual mute, a high-performance amplifier, and an under-counter hearing loop for customers using hearing aids. With its durable mild-steel construction and sleek powder-coated finish, it's designed for heavy daily use in busy public environments. And because it's pre-engineered for plug-and-play setup, you can have it up and running quickly once the counter cutouts are made.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-K003 uses advanced technology to ensure high-quality sound and reliable operation. The cardioid staff microphone and omnidirectional customer microphone capture speech clearly, while the precision-tuned amplifier delivers crystal-clear audio on both sides of the barrier. The integrated hearing loop makes it fully accessible, and the flush-mount design keeps the customer counter completely clear with nothing protruding above the surface, ideal for premium installations where visual cleanliness matters. Reliable, efficient, and ADA-friendly, this is the professional standard for modern service counters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between the STS-K003, the STS-K002, and the STS-K001?\u003c\/strong\u003e\u003cbr\u003eA: All three kits provide the same two-way audio and hearing loop functionality. The STS-K003 uses flush-mounted customer speaker (STS-S61) and microphone (STS-M56) modules that install into the counter surface for the cleanest possible look, with nothing protruding above the counter. The STS-K002 uses separate surface-mounted modules (STS-S60 speaker and STS-M54 microphone) that sit on top of the counter.

Whether you're at a drive-up bank teller, ticket window, outdoor pharmacy pickup, or transit fare booth, this system ensures staff and customers can hear each other clearly through glass or a security barrier, and the hyperbolic mesh over the customer-side speaker and microphone gives it a level of environmental durability that standard indoor kits don't offer.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes everything the electronics need for instant clarity: flush-mounted customer speaker (STS-S61-B) and omnidirectional microphone (STS-M56-B) modules with hyperbolic mesh faceplates, a black powder-coated staff microphone and speaker unit (STS-SU1-3W-B) with dual mute, a high-performance amplifier, and a power supply. All customer-facing components install directly into the counter surface for the cleanest possible look, with nothing protruding above the surface. Pre-engineered for plug-and-play setup, you can have it up and running quickly once the counter cutouts are made.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-K003-B-MESH-KIT uses the same proven electronics as Contacta's other STS-K series systems. The cardioid staff microphone and omnidirectional customer microphone capture speech clearly, while the precision-tuned amplifier delivers crystal-clear audio on both sides of the barrier. The difference is on the customer side, where the hyperbolic mesh faceplates protect the speaker and microphone from weather, splashes, dust, and everyday wear that would degrade standard flush plates over time. Rugged, reliable, and designed for high-use environments where a standard intercom would fail early.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between the STS-K003-B-MESH-KIT and the standard STS-K003?\u003c\/strong\u003e\u003cbr\u003eA: The MESH-KIT uses hyperbolic mesh faceplates on the customer speaker and microphone, giving it weather resistance and environmental durability that the standard STS-K003 does not have. It ships only in black powder-coated finish (not Gray Leatherette or Stainless Steel), and the hearing loop aerial is an optional add-on rather than an included component. Choose this kit for outdoor or exposed counters; choose the standard STS-K003 for indoor installations where finish flexibility and an included hearing loop matter more.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this kit include a hearing loop for customers with hearing aids?\u003c\/strong\u003e\u003cbr\u003eA: The hearing loop is available as an optional add-on with this kit.

Whether it's a parking garage entry gate, a fast-food drive-through, a distribution center receiving door, or a mass-testing or health-clinic curbside station, this system delivers high-quality audio through Contacta's weatherproof call unit and dedicated indoor staff speaker\/microphone.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes everything you need: a K009-IP surface-mounted call unit with front-mounted call button, audible alert, and integrated LED for low-light visibility; an STS-SU1-B black staff speaker and microphone unit for the indoor operator station; a high-performance amplifier; a power supply; and an under-counter hearing loop aerial for T-coil-compatible hearing aid users on the staff side. The K009-IP call unit is IP55-rated for protection against water and dust ingress, so it's built to sit outside year-round in real-world weather without degrading.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-K009-IP-L-B pairs a rugged 15W speaker and omnidirectional microphone in the outdoor call unit with a cardioid staff microphone and 5W speaker at the operator station. The precision-tuned amplifier delivers clear audio across the full speech range, while the call unit's LED and audible alert make sure staff know the moment a customer needs attention. Rugged, reliable, and designed for high-traffic entry points where a standard indoor intercom would fail.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does the IP55 rating mean and where can this be installed outdoors?\u003c\/strong\u003e\u003cbr\u003eA: IP55 is an ingress protection rating that means the unit is protected against dust ingress and against water jets from any direction. In practical terms, that means it can be installed on an exterior wall exposed to rain, wind-driven precipitation, and dust without needing an additional weather enclosure. It's suitable for outdoor gates, drive-through windows, parking garages, and similar exposed locations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is different about this kit versus the indoor STS-K001, K002, or K003?\u003c\/strong\u003e\u003cbr\u003eA: The STS-K009-IP-L-B is designed for outdoor entry applications, not indoor counter service. The customer-side unit is a weatherproof call unit with a physical call button and LED for low-light visibility, not a countertop speaker and microphone. It's the right choice for gates, drive-throughs, parking garages, and outdoor pickup or reception windows. Choose the indoor K-series kits for bank teller counters, pharmacy windows, ticket booths, or similar indoor locations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How does the call button work?\u003c\/strong\u003e\u003cbr\u003eA: A customer presses the front-mounted call button on the outdoor unit, which triggers an audible alert on the staff side to notify the operator. Once acknowledged, a handsfree conversation channel opens between the customer and staff.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How many components come in the kit?\u003c\/strong\u003e\u003cbr\u003eA: The complete set includes the STS-A31H amplifier, K009-IP surface-mounted call unit, STS-SU1-B staff speaker and microphone unit, IL-AE99 under-counter hearing loop aerial, and PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this include a hearing loop for customers with hearing aids?\u003c\/strong\u003e\u003cbr\u003eA: The IL-AE99 hearing loop aerial included in the kit is designed for under-counter installation on the staff side. If you need customer-side hearing loop coverage at the outdoor call unit, that's not a standard use case for this kit, contact us at 800-207-2259 to discuss options.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What colors are available?\u003c\/strong\u003e\u003cbr\u003eA: The STS-K009-IP-L-B ships in Black Powder Coated Leatherette.

Whether it's a drive-through pickup window, a ticket booth, a curbside pharmacy or health-clinic window, a transportation depot check-in, or a ferry terminal boarding station, this kit delivers high-quality audio through a weather-rated 30-watt overhead speaker paired with a slim stem microphone on the customer side and a dual-mute staff unit indoors.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes everything you need for a permanent outdoor install: a Contacta STS-S80-IP IP54-rated overhead speaker for high-clarity audio in noisy exterior environments; an STS-M15-300-IP IP54-rated stem microphone that picks up customer speech from the counter or window ledge; an STS-SU1-3W-B black dual-mute staff speaker\/microphone for the indoor operator station; a high-performance amplifier; an under-counter hearing loop aerial for T-coil hearing aid users on the staff side; a power supply; and a 16.4 ft extension cable so you can route the customer-side hardware up to distance without needing to source additional cabling.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-K080-IP pairs a 30W overhead speaker with an omnidirectional stem microphone on the outdoor side, and a cardioid directional staff microphone with a 5W speaker at the operator station. The precision-tuned amplifier delivers clean audio across the full speech range, and the customer-side hardware is IP54-rated to withstand splashing water from any direction along with dust and dirt ingress. Rugged, reliable, and designed for high-traffic outdoor service windows where a standard indoor intercom would degrade quickly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does the IP54 rating mean and where can this be installed outdoors?\u003c\/strong\u003e\u003cbr\u003eA: IP54 is an ingress protection rating that means the unit is protected against dust ingress and water splashing against the enclosure from any direction. In practical terms, that means the outdoor components can be installed at exterior service windows exposed to rain, wind-driven precipitation, and dust without needing an additional weather enclosure. It's suited for drive-through windows, curbside pickup counters, ferry terminals, and outdoor service points.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is different about this kit versus the STS-K009-IP outdoor entry system?\u003c\/strong\u003e\u003cbr\u003eA: The STS-K080-IP is designed for outdoor service windows where a staff member is always present and ready to talk (drive-throughs, curbside pickup, ticket booths). It uses a large 30W overhead speaker and a slim stem microphone that stay on for continuous conversation. The STS-K009-IP is designed for outdoor entry points (gates, security doors) where staff need to be summoned first, so it includes a physical call button that customers press to trigger an audible alert on the staff side. Choose the K080-IP for continuous drive-through-style service; choose the K009-IP for gate or entry-request scenarios.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is the K080-IP different from the indoor STS-K001, K002, or K003 kits?\u003c\/strong\u003e\u003cbr\u003eA: The K080-IP is outdoor-rated (IP54) and uses hardware suited to exposed installations, an overhead speaker mounted above the customer window, and a stem microphone at the counter. The indoor STS-K001, K002, and K003 kits use smaller counter-mounted or flush-mounted speaker\/microphone modules designed for indoor service counters like bank teller windows, pharmacy counters, and ticket booths.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How many components come in the kit?\u003c\/strong\u003e\u003cbr\u003eA: The complete set includes the STS-A31H amplifier, STS-SU1-3W-B black dual-mute staff speaker and microphone unit, STS-S80-IP IP54 overhead speaker, STS-M15-300-IP IP54 stem microphone, IL-AE99 under-counter hearing loop aerial, STS-EX5M 16.4 ft extension cable, and PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why does the kit include a 16.4 ft extension cable?\u003c\/strong\u003e\u003cbr\u003eA: Outdoor installations typically require longer cable runs than indoor kits because the amplifier and staff unit sit inside the building while the speaker and microphone are mounted on the exterior wall or under a canopy. The included 16.4 ft (5 m) extension cable saves you the step of sourcing additional cabling for the customer-side hardware.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this include a hearing loop for customers with hearing aids?\u003c\/strong\u003e\u003cbr\u003eA: The IL-AE99 hearing loop aerial included in the kit is designed for under-counter installation on the staff side, which helps hearing-aid-equipped staff. If you need customer-side hearing loop coverage at the outdoor window, that's not a standard use case for this kit.

The low-profile black ABS puck can sit free-standing on a counter or ledge, or be surface-mounted, giving installers flexibility for banks, ticket counters, information desks, and any indoor service window where clear speech has to reach the customer side without a full staff-unit housing.\u003c\/p\u003e\n\u003cp\u003eBehind the perforated grille, the STS-S70 delivers 5 watts RMS into 4 ohms with 85 dB SPL output at 1 watt \/ 1 meter and a 150 Hz to 10,300 Hz speech-tuned frequency response. The precision-matched driver is the same speaker used inside Contacta's STS-SU1 staff unit, so audio character stays consistent whether you're extending an existing installation, adding a customer-side speaker to a kit, or replacing a damaged unit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the STS-S70 for and where does it typically go?\u003c\/strong\u003e\u003cbr\u003eA: The STS-S70 is a speaker-only pod for the customer side of an indoor window intercom system. It's used at bank teller windows, post office counters, box office ticket windows, information desks, transit fare booths, and government service counters where the customer needs to clearly hear the staff member behind the glass or partition. Because it can either sit free on a counter or be surface mounted, it works in installations where a full flush-mount or larger housing isn't practical.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is the STS-S70 different from the STS-SU1 staff unit?\u003c\/strong\u003e\u003cbr\u003eA: The STS-S70 is speaker-only. The STS-SU1 is a combined speaker and microphone housing designed for the staff (operator) side, with mute controls and a cardioid microphone for outbound speech. Use the STS-SU1 where the operator needs to talk and mute; use the STS-S70 where you only need audio output on the customer side.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Free-standing or surface mount, how do I decide?\u003c\/strong\u003e\u003cbr\u003eA: Free-standing works when the counter is deep enough to place the pod within a foot or two of the customer, and the installation doesn't need a permanent fix. Surface mounting is the right call for permanent installations where the pod needs to stay in one place, resist being knocked around, or route the cable neatly through the counter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What Contacta systems does the STS-S70 work with?\u003c\/strong\u003e\u003cbr\u003eA: The STS-S70 pairs with any Contacta STS-series window intercom amplifier. It uses the same 4Ω speaker load as Contacta's other pods, so it drops into a standard STS-A31 \/ STS-A31H amplifier speaker output without additional matching.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the STS-S70 rated for outdoor use?\u003c\/strong\u003e\u003cbr\u003eA: No, the STS-S70 is an indoor-rated component. If you need a weather-resistant speaker for an outdoor service window, drive-through, or exposed application, use the IP54-rated STS-S80-IP overhead speaker instead. Call us at 800-207-2259 if you're not sure which speaker fits your install.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What comes with it and what do I need to add?\u003c\/strong\u003e\u003cbr\u003eA: The STS-S70 ships as a single speaker pod with a fly lead for connecting to your amplifier's speaker output.

It's the standard setup for bank teller windows, pharmacy counters with acrylic partitions, transit fare booths, ticket windows, government service counters, and any indoor service position that was designed with a hole through the glass from the start.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes everything you need for a permanent glass-mounted install: a Contacta STS-C100 customer-side microphone with the glass mounting kit (fits holes between 2.5\" and 4.0\" in diameter), an STS-S23 overhead speaker with mounting bracket that projects clear speech down to the customer at the counter, an STS-SU1-3W-G grey staff unit combining a cardioid microphone with mute and a 5W speaker for the operator, a high-performance STS-A31H amplifier, an IL-AE98 window-mounted hearing loop aerial for T-coil hearing aid users, and a PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-S23 overhead speaker and STS-SU1-3W staff unit both run 5 W RMS into 4 ohms with 85 dB SPL output at 1 watt \/ 1 meter across a 150 Hz to 10,300 Hz speech-tuned range. The STS-C100 customer microphone is a cardioid aluminum electret with a wider 70 Hz to 10,300 Hz response tuned to pick up the customer's voice at close range through the glass mount. The full system is CE, RoHS, and WEEE compliant, and the hearing loop is certified to BS EN 60118-4 when installed correctly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What kind of installation is this kit designed for?\u003c\/strong\u003e\u003cbr\u003eA: The STS-K020-S23 is designed for indoor service windows where the security glass or acrylic partition has a pre-cut communication hole between 2.5\" and 4.0\" in diameter. The customer microphone mounts directly on the glass over the hole, so the customer's voice reaches the microphone cleanly without having to route through a counter-mounted speaker pod. Typical installs are bank teller windows, pharmacy consultation counters with barrier glass, transit fare booths, ticket windows, and government service counters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: My glass hole is bigger than 4 inches, will this kit work?\u003c\/strong\u003e\u003cbr\u003eA: No, the STS-C100 mounting plate included with this kit is sized for holes between 2.5\" and 4.0\". For holes between 4.0\" and 5.0\", you'll need Contacta's STS-C200 customer unit instead of the STS-C100. If you're not sure what size hole you have or which kit fits, call us at 800-207-2259, and we'll help you pick the right one.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is this different from the STS-K002 or K003 counter-mount kits?\u003c\/strong\u003e\u003cbr\u003eA: The K002 and K003 kits are designed for installations where the customer-side hardware sits on the counter next to or in front of the glass, not through it. Use those when you don't have (or don't want) a hole in the glass. Use the STS-K020-S23 when the glass was designed with a communication hole from the start and the customer speaks directly through it, audio quality is cleaner because there's no glass barrier between the customer's voice and the microphone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What if I don't have a hole in my glass yet?\u003c\/strong\u003e\u003cbr\u003eA: The kit doesn't include glass drilling. If your partition doesn't have a hole yet, plan for a glass installer to core one at 2.5\" to 4.0\" diameter before running the intercom installation. Tempered or laminated security glass generally needs to be re-cut or replaced rather than drilled after the fact, so confirm with your glass supplier before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How does the hearing loop work?\u003c\/strong\u003e\u003cbr\u003eA: The included IL-AE98 aerial is a thin (0.10\" deep) 8.5\" x 8.5\" panel that mounts on the window and broadcasts the intercom audio directly into T-coil-equipped hearing aids in the immediate area, giving hearing-aid users a clean signal without ambient noise. It meets BS EN 60118-4 when installed to spec, which is the international standard for hearing loop performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How many components come in the kit?\u003c\/strong\u003e\u003cbr\u003eA: The complete set includes the STS-A31H amplifier, STS-SU1-3W-G grey staff speaker and microphone unit with dual mute, STS-C100 customer-side microphone with glass mounting kit and hardware, STS-S23 overhead speaker with mounting bracket, IL-AE98 window-mounted hearing loop aerial, and PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is installation complicated?\u003c\/strong\u003e\u003cbr\u003eA: The electronics are plug-and-play, but the glass mount and the overhead speaker require permanent mounting and cable routing back to the amplifier.

This is the kit for bank teller windows behind bullet-resistant glass, credit union cash counters, embassy visa windows, courthouse clerk stations, cash-transfer and armored-car counters, jewelry buy-back windows, and any other service position where the glass has been specified as ballistic and the intercom hardware needs to match the security rating of the barrier.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes a Contacta STS-C200 ballistic-rated customer-side microphone with the glass mounting kit (fits holes between 2.5\" and 5.0\" in diameter), an STS-S23 overhead speaker with mounting bracket that projects clear speech down to the customer position, an STS-SU1-3W-G grey staff unit combining a cardioid microphone with dual mute and a 5W speaker for the operator, a high-performance STS-A31H amplifier, an IL-AE98 window-mounted hearing loop aerial for T-coil hearing aid users, and a PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-S23 overhead speaker and STS-SU1-3W staff unit both run 5 W RMS into 4 ohms with 85 dB SPL output at 1 watt \/ 1 meter across a 150 Hz to 10,300 Hz speech-tuned range. The C200 is engineered to survive Ballistic Level 3 impact on the customer side of the glass, which means the microphone assembly stays intact if the glass takes rounds during an incident, keeping the intercom operational during the same event the ballistic glass is protecting against. The full system is CE, RoHS, and WEEE compliant, and the hearing loop is certified to BS EN 60118-4 when installed correctly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does \"Ballistic Level 3 Rated\" mean and which standard does it reference?\u003c\/strong\u003e\u003cbr\u003eA: Ballistic Level 3 designates hardware engineered to survive ballistic impact from the customer side of a service window. Different testing bodies publish \"Level 3\" ratings with different threat models (UL 752 Level 3 addresses .44 Magnum rounds, NIJ Level IIIA addresses 9mm and .44 Magnum, EN 1063 BR3 addresses .357 Magnum). Contacta publishes the STS-C200 as Ballistic Level 3 rated.

What sets the K021 apart from Contacta's other glass-mount kits is the STS-BL0 customer unit, a single Silver Sparkle-finished puck that combines the speaker and microphone into one all-in-one component mounted through the glass. That simplifies the install to a single customer-side hole and a single mounting kit, and it gives the finished counter a cleaner visual profile than kits with a separate overhead speaker and stem microphone. It's the right pick for indoor bank teller windows, credit union cash counters, transit fare booths, information desks, box office ticket windows, and government service counters where a permanent glass-mount install is planned, and the buyer wants everything integrated into one customer-facing unit.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes a Contacta STS-BL0 all-in-one glass-mounted customer speaker and microphone puck with the mounting kit, an STS-SU1-3W-SIL-400 Silver Sparkle finished staff unit with a 15.75-inch gooseneck microphone stem and a 5W speaker for the operator, an STS-A31H-BL8 window intercom amplifier, an IL-AE98 window-mounted hearing loop aerial for T-coil hearing aid users, and a PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-BL0 customer unit runs 5 W RMS into 4 ohms with 85 dB SPL output at 1 watt \/ 1 meter across a 150 Hz to 10,300 Hz speech-tuned range on the speaker side, and an omnidirectional cardioid-style microphone with a 100 Hz to 10,000 Hz response tuned to pick up the customer's voice from any angle at the puck. The staff-side STS-SU1-3W speaker matches the customer-side speaker specs, so both sides of the conversation have the same audio character. The STS-A31H-BL8 amplifier precision-drives both sides with less than 5 percent total harmonic distortion. The full system is CE, RoHS, and WEEE compliant; the amplifier meets FCC Class B EMC emissions and ICES-003.\u003c\/p\u003e\n\u003cp\u003eNote that the STS-K021 is not ballistic-rated.

It combines the same amplifier, staff unit, and hearing loop as Contacta's non-ballistic STS-K021 kit with a ballistic-rated all-in-one STS-BL3 speaker and microphone puck that mounts through a hole in the security glass. This is the kit for bank teller windows behind UL 752 rated glass, credit union cash counters, embassy visa windows, courthouse clerk stations, cash-transfer and armored-car counters, jewelry buy-back windows, prison and detention visitor windows, and any other service position where the barrier is specified as ballistic and the intercom hardware needs to match the security rating of the glass.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes a Contacta STS-BL3 UL 752 Level 3 rated customer-side speaker and microphone puck with the glass mounting kit, an STS-SU1-3W-SIL-400 Silver Sparkle finished staff unit with a 15.75-inch gooseneck microphone stem and a 5W speaker for the operator, an STS-A31H-BL8 window intercom amplifier, an IL-AE98 window-mounted hearing loop aerial for T-coil hearing aid users, and a PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-BL3 customer unit runs 5 W RMS into 4 ohms with 85 dB SPL output at 1 watt \/ 1 meter across a 150 Hz to 10,300 Hz speech-tuned range on the speaker side, and an omnidirectional microphone with a 100 Hz to 10,000 Hz response tuned to pick up the customer's voice from any angle at the puck. The staff-side STS-SU1-3W speaker matches the customer-side speaker specs, so both sides of the conversation have the same audio character. The STS-A31H-BL8 amplifier precision-drives both sides with less than 5 percent total harmonic distortion. The full system is CE, RoHS, and WEEE compliant; the amplifier meets FCC Class B EMC emissions and ICES-003; the customer-side hardware is UL 752 Level 3 ballistic-rated.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does UL 752 Level 3 mean and what does it protect against?\u003c\/strong\u003e\u003cbr\u003eA: UL 752 is Underwriters Laboratories' standard for ballistic-resistant materials, equipment, and armor. Level 3 within that standard specifies that the hardware is tested to stop three rounds of .44 Magnum lead semi-wadcutter gas checked ammunition fired from 15 feet. In practical terms, the STS-BL3 customer-side puck is engineered to survive that threat profile from the customer side of the glass, keeping the intercom operational during the same event the ballistic glass is protecting against. Match the intercom rating to your glass supplier's rating — if your barrier is UL 752 Level 3, this is the correct intercom pair for it.

Level 8 is the top of Contacta's UL 752 ballistic ladder and is engineered to survive rifle-caliber threats, not just handgun rounds. This is the kit for military and federal building visitor windows, embassy consular sections at high-threat posts, courthouse and federal marshal service windows in high-security jurisdictions, maximum-security correctional facility visitor stations, cash-transfer and armored-car counters with rifle-rated glass, nuclear regulatory and defense contractor reception windows, and any other service position where the barrier is specified as UL 752 Level 8 and the intercom hardware needs to match the rating of the glass.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes a Contacta STS-BL8 UL 752 Level 8 rated customer-side speaker and microphone puck with the glass mounting kit, an STS-SU1-3W-SIL-400 Silver Sparkle finished staff unit with a 15.75-inch gooseneck microphone stem and a 5W speaker for the operator, an STS-A31H-BL8 window intercom amplifier, an IL-AE98 window-mounted hearing loop aerial for T-coil hearing aid users, and a PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-BL8 customer unit runs 5 W RMS into 4 ohms with 85 dB SPL output at 1 watt \/ 1 meter across a 150 Hz to 10,300 Hz speech-tuned range on the speaker side, and an omnidirectional microphone with a 100 Hz to 10,000 Hz response tuned to pick up the customer's voice from any angle at the puck. The staff-side STS-SU1-3W speaker matches the customer-side speaker specs, so both sides of the conversation have the same audio character. The STS-A31H-BL8 amplifier precision-drives both sides with less than 5 percent total harmonic distortion. The full system is CE, RoHS, and WEEE compliant; the amplifier meets FCC Class B EMC emissions and ICES-003; the customer-side hardware is UL 752 Level 8 ballistic-rated.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does UL 752 Level 8 mean and what does it protect against?\u003c\/strong\u003e\u003cbr\u003eA: UL 752 is Underwriters Laboratories' standard for ballistic-resistant materials, equipment, and armor. Level 8 within that standard specifies that the hardware is tested to stop five rounds of 7.62mm NATO M80 rifle ball ammunition (roughly equivalent to .308 Winchester) fired from 15 feet at approximately 2,750 feet per second. This is a rifle-caliber threat model, several tiers above the handgun-rated Levels 1 through 4, and is the specification typically required for military installations, federal facilities in high-threat postings, and maximum-security correctional visitor stations. The STS-BL8 customer-side puck is engineered to survive that threat profile from the customer side of the glass, keeping the intercom operational during the same event the ballistic glass is protecting against.

Instead of a stem microphone or an all-in-one puck, the B94 is a curved bar unit that mounts on the customer side of the counter with a low-profile base and an arcing microphone housing that wraps partially around the customer's speaking position. The curve is available with either a left or right orientation so the microphone geometry matches the customer's approach direction, and the whole kit ships in a coordinated Gray Leatherette or Black Textured finish so the staff unit and customer unit visually match once installed.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes a Contacta STS-B94 (left or right curve) half-bridge bar customer microphone with speaker, an STS-SU1-3W staff unit combining a cardioid microphone with dual-mute controls and a 5W speaker for the operator, an STS-A31H window intercom amplifier, an IL-AE99 under-counter hearing loop aerial (molded on site to the required size by your installer), and a PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-B94 customer unit runs 5 W RMS into 4 ohms with 85 dB SPL output at 1 watt \/ 1 meter across a 150 Hz to 11,000 Hz speech range on the speaker side, and a cardioid microphone with an extended 70 Hz to 14,000 Hz frequency response that captures more of the customer's voice character than the standard 100 Hz to 10,000 Hz microphones used in Contacta's other indoor kits. The staff-side STS-SU1-3W matches the customer speaker on frequency response and a 5W output. The STS-A31H amplifier precision-drives both sides with less than 5 percent total harmonic distortion. The system is CE, RoHS, and WEEE compliant, and the hearing loop is certified to BS EN 60118-4 when installed correctly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the half-bridge bar customer microphone and why choose it?\u003c\/strong\u003e\u003cbr\u003eA: The STS-B94 is a curved bar unit that mounts flat on the customer side of the counter with a low-profile base and an arcing microphone housing. Unlike a stem microphone that stands vertically, the bar shape sits close to the counter and wraps partially around the customer's speaking position, improving voice pickup at close range and giving the counter a cleaner, more architectural look than a taller stem or puck. Choose the K035 when you want an intercom that reads as counter furniture rather than a separate audio component.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I pick between Left Hand and Right Hand curve?\u003c\/strong\u003e\u003cbr\u003eA: The B94's curve is directional; it wraps around the customer from one side or the other. Pick the orientation that matches how the customer approaches your counter and which side of the counter the intercom sits relative to the customer's dominant speaking position. If your counter has fixed seating on the staff side and a walk-up window on the customer side, the curve typically opens toward the customer's approach path so the microphone stays close to their mouth without them having to reposition. If you're not sure which orientation your install needs, call us at 800-207-2259 and we'll help you spec it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is this different from the STS-K002 or K003 counter-mount kits?\u003c\/strong\u003e\u003cbr\u003eA: The K002 uses a surface-mounted flat plate customer unit, and the K003 uses a flush-mounted plate; both mount the customer speaker and microphone as a low-profile plate at the counter surface. The K035 uses the STS-B94 half-bridge bar, which is a curved above-counter unit with a distinctive architectural profile. Choose the K035 when you want the curved bar aesthetic and a slightly wider microphone frequency response (70 Hz to 14 kHz on the customer side).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How does the hearing loop work?\u003c\/strong\u003e\u003cbr\u003eA: The included IL-AE99 aerial is a copper-wire loop with PVC casing that mounts under the counter. The installer molds it to the required size on site, then connects it to the intercom amplifier. Once installed correctly, it meets BS EN 60118-4, the international standard for hearing loop performance, and broadcasts intercom audio directly to T-coil-equipped hearing aids in the immediate area.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the finish just affect appearance?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Gray Leatherette and Black Textured are both durable powder-coated finishes on mild steel metalwork; the difference is purely visual.

Instead of combining the speaker and microphone into one all-in-one puck or bar, the K058 separates them so each component can be positioned independently for the best acoustic result. The speaker sits low on the counter near the customer's ear; the microphone extends above counter level on a curved boom that arcs cleanly across the glass, keeping the pickup close to the customer's mouth without obstructing sightlines or taking up counter space.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes a Contacta STS-M14-BENT customer glass-mounted microphone with curved tubing, an STS-S60 customer surface-mounted speaker, an STS-SU1-3W staff unit combining a cardioid microphone with dual-mute controls and a 5W speaker for the operator, an STS-A31H window intercom amplifier, an IL-AE99 under-counter hearing loop aerial (molded on site to the required size by your installer), and a PS-55 power supply. \u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-S60 customer speaker runs 5 W RMS into 4 ohms with 85 dB SPL output at 1 watt \/ 1 meter across a 150 Hz to 10,300 Hz speech-tuned range. The STS-M14-BENT customer microphone is a cardioid aluminum electret with a wider 70 Hz to 10,300 Hz frequency response tuned to capture the customer's voice at close range from the curved boom position. The staff-side STS-SU1-3W matches the customer speaker's frequency response and delivers 5W output. The STS-A31H amplifier precision-drives both sides with less than 5 percent total harmonic distortion. The system is CE, RoHS, and WEEE compliant, and the hearing loop is certified to BS EN 60118-4 when installed correctly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the curved-tubing microphone and why choose it?\u003c\/strong\u003e\u003cbr\u003eA: The STS-M14-BENT is a cardioid microphone element mounted on a curved aluminum tubing arm that routes the pickup up and over from a base on the customer side. Instead of a straight vertical stem or a low-profile puck, the bent tubing lets the microphone extend across the counter and stay close to the customer's mouth at a natural speaking height. The result is a cleaner acoustic pickup than a fixed low-position microphone would give, without needing a tall stem sitting straight up on the counter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is this different from the STS-K035 half-bridge bar kit?\u003c\/strong\u003e\u003cbr\u003eA: The \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-k035-window-intercom-system-with-half-bridge-bar-microphone-and-hearing-loop\" rel=\"noopener\" target=\"_blank\"\u003eK035\u003c\/a\u003e combines the customer speaker and microphone into a single half-bridge bar unit at the counter.

Choose the K058 when you want to position each component independently for the best acoustic placement, or when the counter geometry doesn't support the half-bridge bar's fixed footprint.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is this different from the STS-K020-S23 glass-mount kit?\u003c\/strong\u003e\u003cbr\u003eA: The \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-k020-s23-glass-mounted-window-intercom-system-with-overhead-speaker\" rel=\"noopener\" target=\"_blank\"\u003eK020-S23\u003c\/a\u003e uses an overhead-mounted STS-S23 speaker above the glass plus an STS-C100 stem microphone at the counter, and requires a pre-cut communication hole in the glass for the customer microphone unit. The K058 uses a lower-profile surface-mount speaker (STS-S60) and the curved-tubing glass-mount microphone (STS-M14-BENT). Choose the K058 for a lower visual profile and a curved-tubing microphone aesthetic; choose the K020-S23 when the glass already has a communication hole, and you want the higher overhead speaker projection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How does the hearing loop work?\u003c\/strong\u003e\u003cbr\u003eA: The included IL-AE99 aerial is a copper-wire loop with PVC casing that mounts under the counter.

Unlike a low-profile puck, a stem microphone, or the half-bridge bar in the STS-K035, the K060's STS-B90-SS customer unit is a full-arch bar that spans nearly 23 inches across the customer side of the counter, with the speaker built into one end and the microphone integrated into the arch itself. The result is a symmetric, upmarket look at the customer window and a fully coordinated brushed stainless finish across the staff unit and customer unit.\u003c\/p\u003e\n\u003cp\u003eThe complete kit includes a Contacta STS-B90-SS brushed stainless slimline bridge bar customer speaker and microphone unit, an STS-SU1-SS-3W brushed stainless staff unit combining a cardioid microphone with dual-mute controls and a 5W speaker for the operator, an STS-A31H window intercom amplifier, an IL-AE99 under-counter hearing loop aerial (molded on site to the required size by your installer), and a PS-55 power supply.\u003c\/p\u003e\n\u003cp\u003eBehind the scenes, the STS-B90-SS customer speaker runs 5 W RMS into 4 ohms with 85 dB SPL output at 1 watt \/ 1 meter across an extended 150 Hz to 11,000 Hz speech-tuned range on the speaker side, and a cardioid aluminum electret microphone with a 70 Hz to 10,300 Hz frequency response integrated into the bridge arch. The staff-side STS-SU1-SS-3W matches the customer speaker specs. The STS-A31H amplifier precision-drives both sides with less than 5 percent total harmonic distortion. The system is CE, RoHS, and WEEE compliant, and the hearing loop is certified to BS EN 60118-4 when installed correctly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFAQS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the slimline bridge bar and why choose it?\u003c\/strong\u003e\u003cbr\u003eA: The STS-B90-SS is a full-width bar unit that arches across the customer side of the counter with a low-profile base at each end, a speaker built into one end, and a cardioid microphone integrated into the arch. Instead of a discrete puck or a curved stem that wraps to one side, the bridge bar spans the full customer position symmetrically. The result is a distinctive architectural piece that reads as intentional design rather than an add-on component, and gives the counter a coordinated brushed stainless steel presence.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How is this different from the STS-K035 half-bridge bar kit?\u003c\/strong\u003e\u003cbr\u003eA: The \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-k035-window-intercom-system-with-half-bridge-bar-microphone-and-hearing-loop\" rel=\"noopener\" target=\"_blank\"\u003eK035\u003c\/a\u003e uses the STS-B94 half-bridge bar, which is a curved arm that wraps to one side (left or right) with an approximately 10-inch curve width, in Grey Leatherette or Black Textured finish. The K060 uses the STS-B90-SS full-width slimline bridge bar that spans nearly 23 inches across the customer side symmetrically, in brushed stainless steel only. Choose the K060 for a wider, more architectural bridge span in stainless; choose the K035 for a shorter half-bridge in a softer leatherette or textured finish.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the kit only come in brushed stainless steel?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The STS-K060 ships in brushed stainless steel across both the customer bridge bar and the staff unit. Contacta doesn't offer this kit in the Grey Leatherette or Black Textured finishes used on other STS kits. The amplifier remains matt black regardless.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is the bridge bar symmetric, or does it come in left and right variants?\u003c\/strong\u003e\u003cbr\u003eA: The B90-SS bridge bar is symmetric across the customer position; no left-hand or right-hand orientation is needed because the arch spans both sides of the customer area. If your counter needs a directional curve wrapping to one side only, look at the K035, which is available in left-hand and right-hand curve orientations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How does the hearing loop work?\u003c\/strong\u003e\u003cbr\u003eA: The included IL-AE99 aerial is a copper-wire loop with PVC casing that mounts under the counter.

The customer position uses a glass-mounted microphone on a slim, silver-anodized stem paired with an overhead speaker, both mounted above or through the barrier rather than sitting on a counter where a frustrated customer could grab, pull, or knock them loose. The staff side runs Contacta's all-in-one gooseneck microphone and loudspeaker unit with dual mute, wired back through the STS-A31H open-duplex amplifier so both parties can speak at the same time without the clipped, walkie-talkie feel of half-duplex systems. An under-the-counter IL-AE99 hearing loop aerial is included to extend the audio directly to any customer whose hearing aid is switched to the T-coil position, and the whole kit meets BS EN 60118-4 in correctly installed hearing loop applications.\u003c\/p\u003e\n\u003cp\u003eThe STS-K064 is the anti-vandal counterpart to Contacta's counter-mounted kits: rather than a customer-side speaker sitting on the counter within reach, the STS-S23 overhead speaker mounts above the customer position in a RAL 9006 semi-gloss powder-coated mild steel housing, and the STS-M14-300 glass-mounted microphone protrudes through the barrier on a 11.8-inch stem with a low-profile 1.2-inch head. That combination suits bank teller windows, post office counters, pharmacies, hospital and health clinic reception, government facilities, information centers, airport counters, supermarket checkouts, ticket kiosks, and nursing home reception, where public-facing hardware sees heavy use and must be difficult to damage.\u003c\/p\u003e\n\u003cp\u003eContacta ships the STS-K064 as a complete system with the STS-A31H amplifier, STS-SU1-G-3W staff unit, STS-M14-300 glass-mounted microphone, STS-S23 overhead speaker, IL-AE99 under-counter hearing loop aerial, and PS-55 power supply. The staff unit and overhead speaker are grey powder-coated finishes; the glass-mount microphone is silver anodized aluminum. Contacta certifies the system as CE-, RoHS-, and WEEE-compliant.\u003c\/p\u003e\n\u003cp\u003eIf your counter position calls for a more compact setup with a countertop customer speaker rather than an overhead one, see our other Contacta window intercom kits.

The customer position uses the small STS-S61-B-NG speaker and STS-M56-B-NG microphone, housed in Zintec cases that mount flush into a deal drawer, tray, or frame with the included mounting plates, so the audio hardware stays hidden inside the barrier. The staff side runs Contacta's free-standing STS-SU1-3W gooseneck microphone and loudspeaker unit with dual mute, wired back through the STS-A31H open-duplex amplifier so both parties can speak at the same time without the clipped, walkie-talkie feel of half-duplex systems.\u003c\/p\u003e\n\u003cp\u003eThe STS-SS is the right kit when the counter is already using a physical deal drawer or deal tray to pass documents and money between customer and staff, and you want the intercom audio integrated into that same fixture rather than added on top of it. That combination suits bank teller windows, pharmacies dispensing prescriptions through a drawer, ticket offices at museums or transit hubs, embassies, government facilities, correctional facilities and prison visitation, and medical dispensaries, where a pass-through drawer is already part of the workflow, and the intercom needs to fit inside it.\u003c\/p\u003e\n\u003cp\u003eContacta ships the STS-SS as a complete system with the STS-A31H amplifier, STS-SU1-3W staff unit, STS-S61-B-NG customer speaker, STS-M56-B-NG customer microphone, and PS-55 power supply. The staff unit is available in grey (STS-SS-G), black (STS-SS-B) powder-coated mild steel or stainless steel (STS-SS-SS); the amplifier ships in a textured black powder coat. Contacta certifies the system as CE-, RoHS-, and WEEE-compliant.\u003c\/p\u003e\n\u003cp\u003eIf your counter position uses a fixed glass or acrylic barrier rather than a deal drawer, see our other Contacta window intercom kits.

Open-duplex operation lets both parties speak at the same time without the clipped, walkie-talkie feel of half-duplex systems, and constant-current hearing loop drive with an engineer-adjustable level lets the amplifier drive an IL-AE98 or IL-AE99 hearing loop aerial so customers with hearing aids in the T-coil position pick up the audio directly.

The aerial transmits the audio signal from a Contacta hearing loop driver as a magnetic field through the glass, and any customer with a hearing aid or cochlear implant switched to the T-coil (telecoil) position picks up the audio directly in their device, cutting out ambient noise and letting them hear the staff side clearly through the barrier.\u003c\/p\u003e\n\u003cp\u003eThe window-mounted design solves three problems that a counter-top or wall aerial does not. First, the aerial mounts on the glass barrier rather than the counter, freeing up counter space that would otherwise be taken by a countertop stand or a wall-hung sign. Second, when the customer side of the counter is outdoors (drive-through pharmacy, ticket booth, airport tarmac counter, outdoor bank teller), the aerial stays indoors on the staff side of the glass, out of the weather. Third, the large blue T-coil sign is visible to the customer through the window from the moment they approach the counter, so hearing-aid users know a hearing loop is available before they start the transaction.\u003c\/p\u003e\n\u003cp\u003eThe IL-AE98 is designed to work with Contacta's hearing loop drivers, including the \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-a31h-window-intercom-amplifier\" rel=\"noopener\" target=\"_blank\"\u003eSTS-A31H\u003c\/a\u003e window intercom amplifier's built-in hearing loop drive, and connects via the included 6.5-foot cable.

Rather than a fixed panel like the IL-AE97 above-the-counter aerial or the IL-AE98 window-mounted aerial, the IL-AE99 is a flexible 6-foot copper wire in a black PVC jacket that installers shape to match the counter's footprint and secure to the underside of the counter with self-adhesive clips, P-clips, or hot glue. Once installed, the aerial transmits a magnetic field up through the counter surface, and any customer with a hearing aid or cochlear implant switched to the T-coil (telecoil) position picks up the audio directly in their device from the hearing loop driver.\u003c\/p\u003e\n\u003cp\u003eThe under-the-counter design is the right choice in three specific scenarios.

Second, when a T-coil sign is already provided elsewhere at the service point (a wall-mounted sign, a printed handout, a POS screen prompt) and the aerial just needs to deliver signal. Third, when the barrier or counter geometry doesn't accommodate the flat panels of the IL-AE97 or IL-AE98.

Outdoor overhead speakers mount above the customer position on the exterior wall or under a canopy, projecting speech down to the customer from a weather-rated enclosure that stays sealed against rain, wind-driven precipitation, and dust ingress. That makes the STS-S80-IP the right choice for drive-through pickup windows, ticket booths at ferry terminals and transit stations, curbside pharmacy and health-clinic counters, outdoor service windows at banks and government facilities, and any customer-side service point where the hardware is exposed to the weather.\u003c\/p\u003e\n\u003cp\u003eThe STS-S80-IP carries an IP54 ingress protection rating, meaning the enclosure is protected against dust ingress and water splashing from any direction. In practical terms, that means the speaker can be mounted at an outdoor service window exposed to rain, blowing snow, and dust without needing an additional weather enclosure. Combined with Contacta's matt black finish, the STS-S80-IP is built to spend years outdoors in high-traffic public installations where a standard indoor overhead speaker would degrade in a season.\u003c\/p\u003e\n\u003cp\u003eAudio-wise, the STS-S80-IP steps well above Contacta's indoor overhead speakers. It delivers 30 watts RMS into an 8-ohm impedance (six times the output of the indoor \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-s23-overhead-speaker\" rel=\"noopener\" target=\"_blank\"\u003eSTS-S23\u003c\/a\u003e), with 88 dB SPL at 1 watt at 1 meter and a wide 120 Hz to 20,000 Hz frequency response. The high output power and extended frequency range are specifically designed to cut through outdoor noise, including vehicle traffic at drive-through windows, wind at ferry terminals, and ambient activity at outdoor transit platforms, so customers can clearly understand the staff member on the other side of the glass or barrier.\u003c\/p\u003e\n\u003cp\u003eThe STS-S80-IP is tuned to pair with the Contacta \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-a31h-window-intercom-amplifier\" rel=\"noopener\" target=\"_blank\"\u003eSTS-A31H\u003c\/a\u003e window intercom amplifier and the \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-ps-55-power-supply\" rel=\"noopener\" target=\"_blank\"\u003ePS-55 power supply\u003c\/a\u003e, the same amplifier and power supply used across most of Contacta's window intercom family.

This freestanding desktop unit combines a 5-watt staff speaker, a cardioid directional microphone on a semi-rigid stem with an adjustable neck, and a three-position dual mute switch that gives staff on-the-fly control over which microphones are open at any moment.\u003c\/p\u003e\n\u003cp\u003eThe dual mute switch is the STS-SU1-3W's main differentiator over a basic speaker-and-microphone unit. The switch has three positions: mute the staff microphone only (customer can still speak to staff, but staff conversation stays private on the staff side), mute both the staff and customer microphones (full privacy on both sides for a side conversation or a manager huddle), or both microphones open (normal two-way conversation). That gives the operator a quick way to pull a manager over for a question, discuss something privately with a coworker, or let the customer finish a phone call without the counter hardware broadcasting the audio back and forth.\u003c\/p\u003e\n\u003cp\u003eThe cardioid directional microphone picks up the operator's voice from directly in front of the microphone head and rejects sound from the sides and rear, which matters at a busy teller window or ticket counter where ambient noise from the lobby or the next operator over would otherwise bleed into the customer-side audio. The semi-rigid stem with adjustable neck lets the operator position the microphone head at the right height and angle for their seated or standing posture, so the microphone sits consistently close to the mouth for clear pickup across staff shift changes.\u003c\/p\u003e\n\u003cp\u003eThe 5-watt staff speaker runs at 4-ohm impedance with 85 dB SPL output at 1 watt at 1 meter, and a 150 Hz to 10,300 Hz frequency response tuned for clear speech reproduction at desk distance.

The microphone element sits on top of a straight 11.8-inch aluminum stem with a silver anodized finish, mounted to the glass partition so the pickup head extends through the glass to mouth height on the customer side. At 1.10 pounds, the M14-300 is roughly three times the weight of Contacta's lighter curved-tubing STS-M14-BENT variant because the stem is purpose-built for rugged service rather than for aesthetic styling.\u003c\/p\u003e\n\u003cp\u003eThe anti-vandal positioning matters at service windows exposed to the public where a customer-side microphone can take abuse: supermarket checkouts, government building service counters, public transit fare booths, airport check-in and information desks, and any high-traffic customer-facing counter where a lighter microphone would be at risk of being bent, broken, or torn out. The aluminum stem and anodized finish resist denting, chipping, and corrosion in high-traffic public environments, and the uni-directional cardioid pickup pattern rejects ambient lobby noise from the sides and rear so the customer's voice gets through to the staff side clearly even in loud spaces.\u003c\/p\u003e\n\u003cp\u003eThe cardioid directional microphone picks up the customer's voice from directly in front of the microphone head and rejects sound from the sides and rear. That is specifically important in high ambient noise environments where multiple customers may be queued at adjacent service positions, HVAC and refrigeration systems add constant background noise, or lobby PA announcements compete with the counter conversation. The microphone's 100 Hz to 5 kHz frequency response covers the full intelligibility range for speech without wasting sensitivity on sub-bass or ultrasonic frequencies that don't carry useful voice information.\u003c\/p\u003e\n\u003cp\u003eTechnical specs: cardioid directional response, -47 ±3 dB sensitivity at 1 kHz, 680-ohm output impedance at 1 kHz.

The microphone element sits on top of a straight 11.8-inch stem in black powder-coated ABS plastic and stainless steel, mounted to the exterior wall or window frame so the pickup head sits at mouth height for the customer on the outdoor side. The 6.56-foot cable routes back through the wall to the amplifier and staff unit on the interior side. Hardware and adhesive pads for installation are included.\u003c\/p\u003e\n\u003cp\u003eIP54 rating means the enclosure is protected against dust ingress and water splashing from any direction. In practical terms, that covers drive-through pickup windows, curbside pharmacy or health-clinic counters, ticket booths and ferry terminals, outdoor gates and security doors, transportation and distribution depot check-in windows, and the drive-through and outdoor mass-testing stations that became common in healthcare operations. A standard indoor stem microphone will degrade quickly in those environments as moisture reaches the microphone element and the ABS joints; the STS-M15-300-IP is specifically rated for permanent exterior exposure.\u003c\/p\u003e\n\u003cp\u003eThe microphone uses an omnidirectional pickup pattern rather than the cardioid pattern on Contacta's indoor stem microphones. For outdoor service windows and drive-through counters, the customer is not always positioned directly in front of the microphone (different vehicle heights at a drive-through, customers standing at an angle to a window ledge, children or wheelchair users at a different height than the designed mouth position), so an omnidirectional pattern picks up the customer's voice from any angle at the counter. The trade-off is slightly more ambient noise pickup than a cardioid pattern, which is a reasonable trade-off in open outdoor acoustics where there is less reverb and less constant background noise than a crowded indoor lobby.\u003c\/p\u003e\n\u003cp\u003eTechnical specs: omnidirectional directional response, -42 ±3 dB sensitivity (0 dB = 1 V\/Pa), 2.2 kΩ impedance, 100 Hz to 20,000 Hz frequency response.
