Aiphone GTA-DESB
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.
