Docking Station:


The M&S DMC3-4 Retrofit Master Station requires individual wire that is run from the master to each intercom speaker. If the master is replaced, all other components except wire and M&S music and door speakers with round bell buttons must also be replaced.  (The exceptions are M&S MC302 and MC602 systems without CD or cassette players.  Only the master and update frame have to be purchased when replacing these models.)

The 3-wire intercom system replacement allows 13 remote stations and 3 door speakers.  The 4-wire intercom system replacement allows 15 remote stations and 3 door speakers.

The DMC3-4 features:

  • Automatic on/off
  • A full clock radio that supports waking up or falling asleep to music
  • A built-in AM/FM radio tuner that offers (8) AM and (8) FM radio station presets
  • (2) Music source inputs
  • The ability to control music source and radio station from intercom stations
  • Monitor capability for infants and elderly
  • Intercom only and optional door release
  • Programmable monitor override
  • Optional 3 note or 8 note door chime modules

Optional CD/MP3 player and Bluetooth and MP3 Player are available for purchase separately.  If just a connection for an MP3 player or smart phone is desired, an external docking station option is available.

    Use with DMC1H housing and DMCFM frame (master only) or DMC1HC combo housing and either DMCFC frame or DMC1F frame (master and CD/MP3 or Bluetooth/MP3 player). Choice of frame when optional CD/MP3 or Bluetooth/MP3 player is installed depends on height of existing hole.

      • Q:

        is there a maintenance battery for time or other function in this system?


        There is no maintenance battery for time with this system.  However there is a capacitor of sorts to save tone volumes and preset radio station for a certain amount of time.  If power goes out for over 15 or more minutes, a lot of times these need to be reset.

      • Q:

        Does the DMC3-4 use a transformer, and is that included in the purchased product? My current MC300 has a transformer (which appears to be the failing component). Thank you.


        The transformer is located in the housing required for the M&S DMC3-4.  The housing in a DMC1H.  If you plan on replacing the entire system, you have to replace all room stations, pation stations, etc.  The MC300 transformer is no longer available.

      • Q:

        Are the demensions (height -5 5/16) and width (15 1/4) inside the wall or outside the wall.


        This is outside of the wall.  The inside dimension are the DMC1H housing which is required for this unit.  These dimensions are 5 1/2"H x 14 1/4"W.

      • Q:

        Can a wireless door chime be integrated to the DMC3-4? For out on the patio.


        These systems are not set up to allow a wireless doorbell. You can add a doorbell but would need to have a wire ran to the location.

      • Q:

        I have a MC602 system. No room speakers, just ceiling speakers with individual volume controls and 1 doorbell. I want to upgrade to Bluetooth and USB port for music input. What do I need to purchase and costs please. Thanks


        To replace the MC602 with Bluetooth, you will need the DMC3-4 master, DMCBT unit, DMC1HC wall housing, and DMCFC frame.

      • Q:

        I just sent you some misinformation. My existing unit is a M&S MC 602 unit. Does the DMC3-4 replace it?


        Yes, the DMC3-4 replaces the MC602.  A new DMCFM frame is definitely required to prevent drywall patching.  Other options would be a TE5D transformer, or DMC1H wall housing if the area would be preferred to have the drywall patched.

      • Q:

        Can the DMC3-4 replace a Nutone IM-3303 master station? Will it work with existing Nutone wall speakers?


        The DMC3-4 along with any other new system would require a full system upgrade.  The existing wiring can be reused, but all room, door, and pation stations need to be replaced.  The new units are smaller but come with trim plates so that there is no drywall patch or repair.  The better options for the 3-wire is the Intrasonic RETRO system or the Nutone NM100.  If the DMC3-4 is preferred, then the kit would need to be customized.

      • Q:

        Need to replace MC602 master unit. Room stations have 4 wires. AM/FM radio only, no CD or other.. What do I need, if anything, other than DMC3-4 and frame? Can I use existing housing (14.25Wx7.25Hx3.875D) and transformer?


        Nothing other then the frame.  You can use the existing transformer.  The screw holes do not line up, but you can make it work.

      • Q:

        I would like to replace a WH35X unit installed since 1993. The unit is working but mechanical volume adjustment and switch controls are rough. Have 2 doorbell/speakers, and 5 large style room intercom/speakers. Is there an upgrade for the Master unit that will work with the current speaker units? Also would like Bluetooth connectivity.


        When this master unit is replaced, all of the speakers have to be replaced.  The existing wire can be used.  We can provide a quote if you tell us the height and width of the room speakers.

      • Q:

        Does this retrofit unit DMC 3-4 SKU22800 have an audio 3.5mm input built in?


        If you choose the external option for docking station it does.  The DMC3-4 only comes with RCA inputs.

      • Q:

        I want to replace my MC602 with DMC3-4. Is there an option for Blue tooth?


        To have bluetooth capability with a DMC3-4 and assuming you don't have a CD or cassette player under the master, you need to purchase the DMCBT bluetooth player, DMC1HC combo wall housing and DMC1F combo frame.  If you plan to replace your intercom speakers, you should purchase the Intrasonic RETRO intercom system with bluetooth.  It is a better system and will end up being less expensive than the M&S system.

      • Q:

        I just replaced my MS602 with the DMC3-4 upgrade replacement SKU22769. Am I suppose to be able to hear music from master speaker? If so mine does not have audio at this speaker. All other room stations,


        Yes you are.  Please check two things. First, make sure the switch on the left hand door that the master switch is set to radio/intercom.  Second, make sure that in the tone settings that the mater volume is up and not just the music volume.  If you have issues from there, please contact us to help.  800-533-3249

      • Q:

        I have a customer with a M&S 602 4 wire intercom system. Will the existing room stations work with the DMC3-4 retrofit master station?


        Yes, the existing room stations from an MC602 system will work with a DMC3-4 master station.  You will also need a DMCFM frame to cover the existing hole if the MC602 is by itself at 16"w x 9"h.

        MS6-FM is not a model number that rings a bell.  Could it be MC602 or something along those lines with an MC###?  Please call in an we can discuss.  800-533-3249

        My house is wired with a MS302 with 4 room and two outside remotes and a doorbell. Can I upgrade with the DMC 3-4 Retrofit Master Station, or would I need other addons?


        You can use the DMC3-4 as long as all other locations are in good shape.  You will need a new wall housing and a gap frame.

      The system is very nice a after little uncertainty the system was installed and it works very well. The radio stations not very clear, it makes background noise. The original is quite old.

      The green wire attachment "block" needs to be more robust. Though it meets the minimum requirement, it could be larger and the wire attachment point secured by something more than a screw of that minimal size. But the unit works very well.

      Retrofit system not as easy to install as your employee said it would be. @ electricians worked for 6 hrs. to install new system. Old intercom dr station caused huge delay in completing entire installation.
