During off hours, when there is no attendant at the front counter, employees in the back office can still talk to your customers, by using the Norcon TTU-302. The TTU-302 barrier intercom system includes two 12 in. prism-shaped inside units (unit A and unit B) and one prism shaped outside unit. Unit A and the outside unit are mounted on the front counter and operate like the basic TTU-3. Unit B is mounted in the back office.

How it Works
If a customer visits the front counter during off hours, the customer can use the “PUSH TO CALL” button, which activates a buzzer in unit B. Employees are able to turn on unit B and talk to the customer. Turning on unit A will automatically turn off unit B, and vice versa.

The TTU-302 incorporates the same high-quality electronics as the basic patent pending Norcon TTU-1 Talk-Thru system.

The TTU-302 comes ready to operate. Unit A, the outside unit, and the "PUSH TO CALL" button are quickly and easily mounted on the countertop on opposite sides of the barrier. Unit B is setup in the back office. An 8 conductors jacketed cable connects unit A and unit B.

All Talk-Thru systems are shipped complete with mounting hardware, instructions, and power supply.
