The GTA-DESB is a modular audio entrance station for the GT Series multi-tenant video intercom system. It is equipped with an audio module for communication, a keypad for direct dialing, and a display module to show a greeting message, tenant directory, and system status. A built-in user guide on the audio module can be configured to display one of six languages. The guide provides operational assistance by lighting the appropriate icon along with the option for audible instruction. The GTA-DESB works on a common bus wiring system, carrying the calling and communication functions on a 2-conductor wire. A separate power supply provides voltage to the tenant directory module, while the power for the audio is supplied on the common bus wires. The entrance station is designed to be semi-flush mounted. For added weather resistance, there is an optional rain hood and a hooded surface mount box available. Use the surface mount box if surface mounting is required.
