The Model DMC3-4 Music/Communication Retrofit System Master is a full-function intercom and music distribution system designed for retrofit applications in residential use. The master unit can replace older Nutone, Mircom and other intercom systems that use three-wire or four-wire connections to the room stations. The system supports up to 15 room stations and up to three door speakers. The built-in AM/FM radio tuner allows setting eight AM station presets and eight FM station presets. The backlit liquid crystal display shows the operation mode, audio source, radio frequency, volume setting, and time. If the optional DMC1MM or DMCMP3 player are installed, the display shows the disc number selected and the track number currently playing.

Room stations have pushbuttons that control the system operation. Retrofit room and patio stations connect to the master unit using the installation’s existing wiring. All room station models can select talk or listen to other room stations, door speakers and the master unit. Each has an intercom volume control. The Model DMC3RS or DMC4RS room stations and DMC3RW or DMC4RW patio stations can select the audio source, control the radio tuner, and set the master music volume.

For access control, the optional Model DRW Door Release Mechanism can be installed and activated from the master unit or room stations. The optional three-note Model MC3 or eight-note Model MC8 chime modules provide a selection of door chime sounds.

Optional Bluetooth®-enabled Intercom and Music System Player

The Model DMCBT is a Bluetooth®-enabled Intercom and Music System Player that offers music playback and adds wireless streaming capability from smartphones, tablets, and other Bluetooth-enabled music/audio streaming products. The DMCBT is available in white, almond, and black.

The DMCBT can function as a wall-mounted ’speakerphone’, allowing users to use their Bluetooth-connected smartphone to accept calls by simply clicking a button on the DMCBT (without picking up the smartphone). On the front of the unit are two microphones and a speaker, allowing users who are near the DMC intercom to communicate hands-free with incoming callers.

When telephone calls are accepted on the DMCBT, the music/program distribution throughout the rest of the house is momentarily paused, and only those near the master station area are able to hear/speak to the incoming caller. Once the caller is disconnected, the selected music/programming being streamed prior to the call through the DMCBT will re-commence. Outbound telephone calls may also be handled through the DMCBT by initiating a call on the smart phone, and talking/listening through the DMCBT. (Similar to making/receiving calls in a vehicle with Bluetooth.)

Features

• Stream music, or other audio programs to the main DMCBT, allowing the music/program to be distributed around a home
• DMCBT includes a pop-out flat ’dock’ to house a smart phone
• The dock has 3.5mm audio input jack and USB-A charging port for convenience and flexibility
• Available in white, almond, or black
