It combines the same amplifier, staff unit, overhead speaker, and hearing loop as Contacta's standard glass-mount kit with a Ballistic Level 3-rated STS-C200 customer microphone assembly that mounts through a hole in the security glass up to 5\" in diameter. 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. If your ballistic glass supplier specified a particular standard, call us at 800-207-2259 and we'll confirm the STS-C200 matches before you order.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: When should I pick the STS-K020-S23-6 over the standard STS-K020-S23?\u003c\/strong\u003e\u003cbr\u003eA: Pick the -6 if your glass is ballistic-rated, if you're building or upgrading a service window where the barrier is designed to stop small-arms fire, or if your existing glass hole is between 4\" and 5\" in diameter. Pick the standard \u003ca href=\"https:\/\/www.safeandvaultstore.com\/products\/contacta-sts-k020-s23-glass-mounted-window-intercom-system-with-overhead-speaker\" rel=\"noopener\" target=\"_blank\"\u003eSTS-K020-S23\u003c\/a\u003e if your glass is standard security acrylic or laminated glass without a ballistic rating and your hole is between 2.5\" and 4\" in diameter. The two kits are otherwise identical, so the choice is driven by the barrier you're mounting through.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What kind of installations is this kit designed for?\u003c\/strong\u003e\u003cbr\u003eA: Bank teller windows behind bullet-resistant glass, credit union cash counters, embassy consular windows, courthouse clerk stations, armored-car and cash-transfer counters, jewelry buy-back and pawn windows, government identification and licensing counters, and prison, detention, or secure-facility visitor windows.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: My glass hole is smaller than 2.5\" or larger than 5\". What are my options?\u003c\/strong\u003e\u003cbr\u003eA: The STS-C200 mounting plate is sized for holes between 2.5\" and 5.0\". Below or above that range, the kit won't seat properly against the glass. Call us at 800-207-2259 with your exact hole diameter and we'll help you spec the right customer microphone, or coordinate with your glass supplier on adjusting the opening.\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 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.\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-C200 Ballistic Level 3 rated 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 more involved than the standard glass-mount kit?\u003c\/strong\u003e\u003cbr\u003eA: The electronics are plug-and-play, same as the standard K020-S23. The ballistic-rated glass mount does require careful installation to preserve the barrier's rating, so plan for a glass installer familiar with ballistic-glass hole preparation and gasketing if the glass isn't already in place with a hole cut.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eBallistic Level 3 Rated Customer Microphone Assembly - STS-C200 hardware engineered to survive ballistic impact on the customer side\u003c\/li\u003e\n\u003cli\u003eLarger Glass Hole Range - Fits pre-cut glass holes between 2.5\" and 5.0\" in diameter\u003c\/li\u003e\n\u003cli\u003eOverhead Speaker with Mounting Bracket - Projects clear speech down to the customer position\u003c\/li\u003e\n\u003cli\u003eDual-Mute Staff Unit - Cardioid microphone with mute function for operator privacy\u003c\/li\u003e\n\u003cli\u003eFull Duplex Communication - Simultaneous two-way audio with no push-to-talk delay\u003c\/li\u003e\n\u003cli\u003eHearing Loop Included - IL-AE98 window-mounted aerial for T-coil hearing aid users\u003c\/li\u003e\n\u003cli\u003eComplete System Kit - Comes with all major components:\n\u003cul\u003e\n\u003cli\u003eSTS-A31H Window Intercom Amplifier\u003c\/li\u003e\n\u003cli\u003eSTS-SU1-3W-G Staff Unit Speaker and Microphone (Dual Mute, Grey)\u003c\/li\u003e\n\u003cli\u003eSTS-C200 Ballistic Level 3 Customer-Side Microphone with Glass Mounting Kit\u003c\/li\u003e\n\u003cli\u003eSTS-S23 Overhead Speaker with Mounting Bracket\u003c\/li\u003e\n\u003cli\u003eIL-AE98 Window-Mounted Hearing Loop Aerial\u003c\/li\u003e\n\u003cli\u003ePS-55 Power Supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eWide Frequency Response - Overhead speaker and staff speaker cover 150 Hz to 10,300 Hz\u003c\/li\u003e\n\u003cli\u003eCompact Amplifier Unit - ABS plastic housing with membrane push-button power control\u003c\/li\u003e\n\u003cli\u003eStandards Compliant - CE, RoHS, and WEEE compliant; hearing loop meets BS EN 60118-4 in correct installations\u003c\/li\u003e\n\u003cli\u003eFlexible Power - PS-55 14V DC supply with efficient low-current operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe STS-K020-S23-6 is designed for indoor service windows behind ballistic-rated glass with communication holes cut through the glass up to 5\".
