The GT-1D from Aiphone is an audio handset tenant station. The GT-1D is an audio only 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 the call is answered by picking up the handset. The GT-1D 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-1D is designed to be surface mounted. Up to four 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 simultaneous via the tenant's handset station when speaking with the visitor.
