Flush Wall-Mounted System - Ideal for HighSecurity Locations
Monitoring the activities of inmates and patients in high-security or sensitive types of areas require a special kind of communication system. The system must be sensitive enough to deliver clear, intelligible communications in high-ambient noise environments. It must be durable enough to withstand a tough environment. And it must provide a measure of control for those responsible for the inmates or patients.
The Alpha Communications®/Norcon TTU-5 is specifically designed to achieve this. It is intended for in-wall installations requiring flush-mounting and bullet-resistance. It is enclosed in a pair of wall-mounted galvanized steel boxes with stainless steel rectangular faces.
How It Works...
The microphone/speaker combination is designed to penetrate high-ambient noise levels. In addition, the TTU-5's circuity shapes and enhances the sound for maximum intelligibility. Its compression circuitry decreases loud, annoying sounds. The microphone/speaker and controls are flush with the panel, assuring a tamper-resistant environment. The operator has access to recessed volume controls.
How To Install...
The unit with the controls goes on the corridor side; the other unit on the inmate or patient side. Simply connect the cable provided to the terminal blocks on the stainless steel plates. Then fasten these plates to the backboxes using the tamper-proof screws and special tool furnished.
The panel on the exterior (corridor) side is connected to a continuous-duty, 117-Volt AC power supply which is stepped down to 12 Volts.
