Products > TTU-7X Intercom

When a security gate or shade makes a TTU intercom with a 2.5 in. deep inside control section impractical, the Norcon TTU-7X is the communication system of choice. The TTU-7X incorporates the Norcon signature faceplate, with a 1 in. deep inside plate, and a separate countermount control unit, similar to the TTU-3X.

How it Works
The TTU-7X incorporates the same high-quality electronics as the basic patented Norcon TTU-1X Talk-Thru system.

Installation of the TTU-7X is a simple, one-person operation. All that’s needed is a 3 - 4 in. cutout in the barrier. The prism unit is designed for countertop mounting on the inside of the barrier. Please specify barrier thickness when ordering.
