MC111DM: Communication System Master with Door Release

The Model MC111DM Communication System Master with Door Release is an intercom system designed for residential use. The system supports up to nine room stations and up to two door speakers. With the optional Model AWPM Audio Input Wall Plate, an external audio source can be connected for music distribution.

Room stations have pushbuttons that control the system operation. All room station models can talk or listen to other room stations, door speakers and the master unit. Each has an intercom volume control. Pressing the latching monitor button on a room station allows that room to be monitored from any of the other rooms or at the master unit.

For access control, the optional Model DRW Door Release Mechanism can be installed and activated from the MC111DM master unit, Model N15D, N15DA, or N35D Room Stations. A three-note Model MC3 door chime in included and provides a selection of three door chime sounds. An optional eight-note Model MC8 chime module can be installed for additional chime sounds.
