Monitoring the activities of inmates and patients in high security
or sensitive areas requires a special kind of communication system.
The intercom system must be sensitive enough to deliver clear, intelligible
communications in high-ambient noise environments, it must be durable,
and it must provide a measure of control for those responsible for
the inmates or patients.
The Norcon TTU-5 is specifically designed for these conditions.
is enclosed in a pair of galvanized steel back boxes with stainless
steel rectangular faces and intended for in-wall installations requiring
flush-mounting and bullet-resistance.
How it Works

the basic patented Norcon TTU-1 Talk-Thru
The microphone/speaker and controls are flush with the panel, assuring
a tamper-resistant environment. The operator has access to recessed
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 back-boxes using the tamperproof screws
and included tool.
The panel on the exterior (corridor) side is connected to a continuous-duty,
90-240 Volt AC power supply which is stepped down to 15 Volts.
TTU-5 systems are shipped complete with back-boxes, mounting hardware,
instructions, and power supply.
