The GH-1AD is an audio only tenant station for the GH series Multi-Unit entry system. It is equipped with a Talk, Door Release, and optional service button. When a visitor calls, the tenant stations rings, and is answered by one touch of the Talk button. The GH-1AD also has the capability of calling the Concierge/Security Guard stations(s), turning on a light while speaking with a visitor at the entrance, receiving an emergency tone from a panic call station, and releasing a door.

The GH-1AD is designed to be surface mounted, and has a slim, streamlined design. Up to four GH-1AD units can be used in the same tenant location. Communication is     hands-free at the entrance station when a tenant answers the call, and is either VOX hands-free or push-to-talk at the tenant station when speaking with the visitor.
