The GT-DM is an all-in-one audio/video entrance station with stainless steel cover for the GT Multi-Unit entry system. This unit is equipped with a 170° angle of view PTZ camera. The 10-key keypad allows for direct digital dialing and access entry. A 3.5″ color LCD displays a greeting message, tenant names & numbers, and system status. The color LCD may be set to energy saver mode and can activate via the built in motion sensor. The GT-DM is equipped with a six language user assistance guide. The guide provides operational assistance by displaying a visual pictogram as well as audible guidance. The GT-DM works on a common bus wiring system, carrying the calling and communication functions on a 2 conductor wire, and the video signal on a second 2 conductor wire. A separate power supply provides voltage for the digital display, while the power for the audio and video is supplied on the common bus wires. The entrance station is designed to be flush mounted but an optional hooded stainless steel surface mount box can be purchased separately (SBX-GTDM). Audio only and audio/video entrance panels are intermixable within a system, as are audio and video tenant stations. The system allows up to two video stations and two audio stations to be used in the same tenant location (exception to this rule if using the GT-2C). Communication is hands free at the entrance station when a tenant answers the call.
