3-Wire Retrofit Indoor Station

Easily replace your outdated 3-wire room station with the M&S DMC Intercom Room Station (Remote Scan, Master Volume, 3-Wire Retrofit). This retrofit indoor station connects to the DMC3-4 Retrofit System Master Station (sold separately) using the existing wiring. It provides indoor audio, as well as communication with the other stations in your system.

  • Advanced indoor station for 3-wire intercom systems only
  • Works with the DMC3-4 Retrofit Master Station
  • Uses existing room station rough-in enclosure and wiring
  • Communicates with all other intercom stations in the system
  • Local controls include volume and talk/listen buttons
  • Remote control for master unit's power, audio source, and volume


Available Colors: White, Almond or Black

The unit features a high-quality 5-inch speaker powered by 30 Watts RMS (delivered by Master Station) with local speaker volume control, talk and listen buttons, audio input and radio station scan buttons, and master volume control buttons for radio, CD, or auxiliary.

How It Works

When the TALK button is pressed, the person at the room station can talk to all other room stations set to intercom or radio/intercom. When the LISTEN button is pressed the person at the room station can listen to all stations set to intercom or radio/intercom. Pressing both TALK and LISTEN buttons communicate with the door speaker.

The volume of the master unit's built-in AM/FM radio receiver, CD and auxiliary audio input can be controlled with the MUSIC VOLUME buttons. The master unit's radio can also be turned on or off using these buttons. Pressing both the MUSIC VOLUME buttons will cause the master unit's radio to scan the preset stations and music sources. Pressing both the MUSIC VOLUME buttons for four seconds can activate an accessory door release mechanism or a security system's panic alarm.

Installation Details

The retrofit room station is designed to fit into the existing room station's rough-in enclosure and connect to the existing wiring. For the recommended room station retrofit frame, purchase the Room Station Retrofit Mounting Frame, model DMCFR (sold separately). The frame should eliminate the need for drywall repair for existing openings up to 7-1/2" x 10".

NOTE: Requires the DMC3-4 Retrofit System Master Station, sold separately.
