GTA-DES

Audio Entrance Station with Digital Directory

DESCRIPTION:

The GTA-DES is an audio entrance station for the GT Multi­Unit entry system. This unit is equipped with an audio
module for communication, a 10-key keypad for direct digital
dialing, and a VFD display for a greeting message, tenant
names & numbers, and system status. The GTA-DES offers

a user guide that can be congured to display any one of

six languages. The guide provides operational assistance
by lighting the appropriate icon as well as offers audible
guidance.
The GTA-DES 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 digital display, while the power for the audio is supplied on
the common bus wires.

The entrance station is designed to be semi-ush mount and

has an optional rain hood or hooded surface mount box to be
used as necessary.
Audio and video entrance panels are intermixable within a
system. Audio and video tenant stations are also intermixable,
allowing up to two video stations and two audio stations to
be used in the same tenant location. (If using the GT-2C, use
only additional GT-2H for total of 4 stations within a tenant
location).
Communication is hands free at the entrance station when a
tenant answers the call.
