The Ideal Counter-Top Communication System

Where It is Impractical to Cut a Hole In the Barrier

There are times when its impractical - for various reasons - to cut a 3- to 4-inch hole through an isolation barrier. But your employees and your customers still have a way to communicate - clearly, calmly. In such cases, the Alpha Communications®/Norcon TTU-3 is the communication system of choice. The prismshaped units of the TTU-3 are ideal for mounting on a countertop on both sides of a barrier. Yet they allow free communication through barriers typically found in banks, cashier's booths, information booths, and similar environments.

How It Works...

The TTU-3 incorporates the same high-quality electronics as the basic (Norcon) patented model TTU-1 Talk-Thru system. It is a duplex system, enabling the attendant and the customer to talk and listen simultaneously. 

The TTU-3 provides clear communication even in environments with high ambient noise, shaping the sound for maximum intelligibility. Its compression circuitry decreases loud, annoying sounds.

How To Install...

The TTU-3 comes ready to operate. The prism units are quickly and easily mounted on the counter-top on opposite sides of the barrier. They can be positioned back-to-back (as shown) or randomly. The unit with the gooseneck microphone and controls goes inside the booth; the unit without controls is mounted outside the booth. There are two ways to install the TTU-3: either run the cable between the units through a small hole in the barrier, or under the counter-top (as shown on next page).

The TTU-3 uses a continuous-duty, 117-Volt AC power supply which is stepped down to 12 Volts.
