The Tech Works VPSS-L is a two gang correctional grade Passive Intercom Speaker Station designed for very demanding environments. The Speaker Station employs a computer designed speaker/microphone and acoustic coupler that delivers superior speech intelligibility. The speaker/microphone is moisture resistant and employs three steel barriers to protect it from tampering and vandalism. The integral “Call-In” switch is hermetically sealed and utilizes a limited travel actuator to protect from excessive force or moisture. An ultra-bright LED call confirmation light built into the button lets the caller know that their call has been placed.
The 12-gauge stainless steel faceplate and tamperproof mounting hardware makes the VPSS-L almost indestructible. A 25 Volt transformer with taps at 1⁄2 and 2 Watts is provided for high sensitivity listening and proper matching for articulate speech output.
