For those times when it’s impractical, for various reasons, to
mount the inside control section of a communicator into a
window, the TTU-7 is the communication system of choice. The
prism shaped control unit of the TTU-7 is ideal for mounting on
a counter top on the interior side of a barrier. The system allows
hands free communications through barriers typically found in
banks, cashier’s booths, ticket windows, information booths
and similar environments.
How It Works...
The TTU-7 incorporates the same high-quality electronics as
the basic (Norcon) patented model TTU-1 Talk-Thru system.
It is a vox system, enabling the attendant and the customer to

How To Install...
Installation of the TTU-7 is a very simple, one-person opera-
tion. All that’s needed is a 3 - 4 inch cutout in the barrier. All
hardware and cable are supplied. Please specify barrier thickness
when ordering. The prism unit is quickly and easily mounted on
the counter-top on the inside of the barrier, at a convenient
location for the user. A power adapter and all cables are supplied.
The TTU-7 is supplied with a continuous-duty, 117-Volt
power supply which is stepped down to 15 Volts.
