Monitoring the activities of inmates and patients in high-secu-
rity or sensitive types of areas require a special kind of commu-
nication system. The system must be sensitive enough to deliver
clear, intelligible communications in high-ambient noise envi-
ronments. 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 environ-
ment. 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.
