The GT-1M-L is an audio/video handset tenant station for the GT series Multi-Unit entry system. It is equipped with Door Release, Option, and Guard buttons.

When a visitor calls, the tenant station rings and video is present. The call is answered by picking up the handset. The GT-1M-L also has the capability of calling the Concierge/Security Guard station(s), turning on a light while speaking with a visitor at the entrance, and receiving an emergency tone from a pull cord or panic call button.

The GT-1M-L is designed to be surface mounted. Up to four units can be used in the same tenant location (2 audio/video and 2 audio only). Communication is hands-free at the entrance station when a tenant answers the call, and is simultaneous via the tenant's handset station when speaking with the visitor.
