The TTU-4’s counter-mounted design eliminates the need for cutting into a barrier. Its low-profile installation adds a personal dimension to such situations as inmate-visitor communications. All the components including the microphones are housed in the sleek, compact units to avoid the hazards that might be encountered in a high-security environment.
How it Works...
The TTU-4 incorporates the same high-quality electronics as the basic patent pending
Norcon TTU-1. Because the TTU-4 is designed for applications in security areas, all controls
and microphones are recessed to minimize unauthorized adjustment and tampering.
Installation...
The TTU-4 comes ready to operate, simply mount the prism units on opposite sides
of the barrier. Tamper-resistant screws are used for both units. The prism units
can be positioned back-to-back or in any other configuration suitable for your
environment. Cables may either be run through a small hole in the barrier, or
under the countertop. All Talk-Thru systems are shipped complete with mounting hardware, instructions,
and power supply.
