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