The Contacta STS-K003 Flush Mounted Window Intercom System is designed for clear, effortless communication in areas where glass or security screens obstruct the view. 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.
The 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.
Behind 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.
FAQS:
Q: What is the difference between the STS-K003, the STS-K002, and the STS-K001?
A: 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. The STS-K001 mounts both customer units on a single steel bridge bar that spans the customer counter.
Q: Does the STS-K003 require counter modification?
A: Yes. Because the customer speaker and microphone are flush mounted, you'll need to cut mounting holes in the counter surface at the installation locations. Refer to the STS-S61 and STS-M56 component dimensions below when planning cutouts.
Q: What types of locations use the STS-K003 system?
A: It's perfect for any environment where glass or barriers make normal conversation difficult, such as banks, post offices, theaters, information centers, public transit systems, ticket counters, embassies, and government buildings.
Q: Does this system include a hearing loop for customers with hearing aids?
A: Yes. The STS-K003 includes an under-counter hearing loop aerial (IL-AE99) that transmits sound directly to hearing aids equipped with a T-coil.
Q: How many components come in the kit?
A: The complete set includes the STS-A31H amplifier, STS-SU1-3W staff microphone and speaker unit (dual mute), STS-S61 customer flush-mounted speaker, STS-M56 customer flush-mounted microphone, IL-AE99 hearing loop aerial, and PS-55 power supply.
Q: Is installation complicated?
A: The electronics are plug-and-play with minimal wiring. The main additional step compared to a surface-mount kit is cutting counter apertures for the flush-mount speaker and microphone.
Q: What colors are available?
A: The STS-K003 is available in three finishes: two powder-coated options (Gray Leatherette / STS-K003-G and Black Textured / STS-K003-B), and a Stainless Steel option (STS-K003-SS).

Yes. Free delivery is included on every safe we sell, anywhere in the lower 48 states. The specific delivery method depends on the safe's weight: small package delivery for under 150 lbs, curbside, or garage delivery for heavier safes. See full shipping details →
Shipping timelines vary by product. Check the availability status at the top of this page for the estimated ship date. Once shipped, transit time typically runs 5–10 business days, depending on your location. You'll receive tracking when the safe leaves the warehouse. Safes under 150 lbs ship via UPS or FedEx Ground, no appointment needed. Safes weighing 150 lbs or more ship via freight (LTL); the freight carrier will contact you directly to schedule a delivery appointment once the safe reaches your local terminal.
We don't provide inside delivery directly, but we work with third-party installers across the country who do. Here's how it works: call us at 800-207-2259 for a recommendation in your area, and we'll provide the names and phone numbers of installers we've worked with. You contact the installer directly to arrange pricing for delivery and installation. Once you've agreed on a price, place your order with us using the installer's address as the shipping destination. The installer receives the safe, inspects it, and schedules your final delivery appointment. Some installers prefer to pick the safe up directly from the freight terminal. See inside delivery details →
Check the product's exterior dimensions (listed above) against your narrowest passage, interior doorways, stair landings, and tight turns. Most people remove the safe from the pallet before moving it indoors, so the safe's actual dimensions are what matter for doorways. Standard interior doorways (30–32" clear) accommodate most residential safes, but measure before ordering. Call us if you're uncertain. See where to locate your safe →
Electronic locks: yes; it takes about 30 seconds. Instructions are included with your safe. Mechanical dial locks: no, changing a dial combination requires a licensed safe technician. Important: attempting to change a dial combination yourself (or having an unlicensed locksmith do it) voids the lock warranty. A licensed safe tech maintains the warranty. See lock operating instructions →
Note: Some mechanical pushbutton locks (like Simplex) can be changed by the user without a technician. Check your specific lock's instructions.
Call us immediately — while you have 24 hours to report damage, calling right away gets the claim filed faster. Take photos of the damage and packaging before moving anything. For minor cosmetic damage, we typically send touch-up paint plus a partial refund. For significant damage, we send replacement parts or arrange a full replacement. Order Protection (optional at checkout) speeds refund payouts to 48–72 hours vs. 30–60 days through standard freight claims; replacement safes ship on the manufacturer's normal timeline regardless. See receiving your safe →
We offer a 30-day return policy on unused, in-original-condition products. The return freight for a heavy safe is substantial, so we strongly encourage you to call us before ordering if you're unsure about fit or configuration. See full return policy →
Yes. Call us Monday–Friday, 8am–5pm Pacific at 800-207-2259. You have two options: we can take the full order by phone (we pause the call recording before you read your card number, so payment info is never stored), or we can build your order and email you a payable invoice link so you can enter your own payment details securely.
