The ready-to-install GT Series GTA-DES Audio Entrance Station with Digital Directory from Aiphone is a modular design audio-only entry panel mounted in a 3-module vertical box. This audio entrance station is designed for use in the GT Series Multi-Unit Entry Security System. The unit comes with GT-DA-L audio module for communication, GT-10K 10-key keypad for direct digital dialing, and GT-NS VFD display for a greeting message, tenant names & numbers, and system status. The entrance station features a user guide that can be configured to display any one of six languages. The guide provides operational assistance by lighting the appropriate icon as well as offering audible guidance.
The GTA-DES station works on a common bus wiring system, carrying the calling and communication functions on a 2-conductor wire (available separately). A separate power supply (not included) provides voltage to the digital display, while the power for audio and video is supplied on the common bus wires. The entrance station is designed to be semi-flush mount with the option of using a rain hood (available separately), or it can be surface-mounted using a hooded box (available separately).
Audio and video entrance panels are interchangeable within a system. Audio and video tenant stations are also interchangeable, allowing up to two video stations and two audio stations to be used in the same tenant location. Communication is hands-free at the entrance station when a tenant answers the call.
Note: If using the GT-2C Audio Bus Control Unit with this entrance station, use only additional GT-2H Sub-master Monitor Station for total of 4 stations within a tenant location.
