Products > Corrections Series > TTU-5 Intercom

Overview
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. It 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 TTU-5 incorporates the same high-quality electronics as the basic patented Norcon TTU-1 Talk-Thru system.

The microphone/speaker and controls are flush with the panel, assuring a tamper-resistant environment. The operator has access to recessed volume controls.

Installation
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.
