The 2053/2054 Nutone radio-intercom is an older unit that is easily replaced by the IM-3303 system or M & S DMC3-4 which offers the opportunity of CD music and stereo speakers. Both system were a 3 wire system. This means that you will be able to use your existing wiring when installing your new system. Below is a list of the old items and the replacement procedure. The first section if for the Nutone upgrade, below will be the section for the M & S DMC3-4 upgrade.
Original Nutone System | Suggested Nutone Replacement | |
2053/2054 Master
| IM-3303 Master
| Both of these systems are a 3-wire system. That means that you will be able to use your existing wiring. The IM-3303 is large enough to cover the old hole, but not large enough to cover the foot print made by the 2053/2054. There is an update frame available(IA-119) that will cover the footprint of the old master. |
2030A Rough-in | IR-104 Rough-in
| The IR-104 rough-in is 1/4" longer and 3/8" narrower than the old rough-in. The little gap on top and bottom of the new rough-in will be covered by the master station. The 2053/2054 has 120 volt AC run to the Rough-in, so wiring power to the IM-3303's 2 transformers is easy. |
N2027 Speaker | IS-338 | The IS-338 is large enough to cover the hole and footprint of the old speakers. |
2025A Rough-in | IR-80 | To install the IR-80, you will have to open up your existing hole by approximately 1" on the sides and 2" top and bottom. |
2021 Inside Speaker | IS-338 with IA-83 Frame | The 2021 is a 12" by 12" speaker. By using the IA-83 adaptor frame with the IS-338, you can cover up your old hole. |
412 Door Speaker | IS-70 with IA-70 Mounting Frame | The 412 was a surface mounted speaker. By using the IA-70 frame, you can surface mount the IS-70 door speaker. Since the IM-3303 is a hands free system, there is no talk/listen switch on the IS-70. When connecting the new system, you would use the silver and center wire and ignore the copper. |
2006 Door Speaker | IS-70 | The IS-70 door speaker will fit right in the existing rough-in. It is a hands free system and only requires that you use 2 of the 3 wires that are running to your front door. You would use the center and silver wire when installing the new door speaker. |
2014 Outside controls | IC-331W | Your controls should be surface mounted, if so they are easily replaceable by the surface mount IC-331W |
2014 Outside Speaker | IS-79 | The 2014 and the IS-79 are similar in appearance. They both have a metal grill. The old 2014 is 1 " larger than the IS-79 but the new IS-79 should mount in the old rough-in. |
The M & S system offers an add-on 6-disc CD player and the option of adding stereo music via the MC960A amplifier.

2067/2067 Master
| DMC3-4
| The DMC3-4 is designed to work with your existing
speaker wires.
The DMC3-4 also gives you the option of true stereo with the MC960A amplifier |
2050A Rough-in | DMC1H ..for use with DMC3-4DMC1HC..for use with DMC3-4 and DMC1CD compact disc player
| The DMC1H is designed to be used with the DMCFR trim
plate to cover the area of the 2067. The DMCFC is the trim plate for the
DMC1HC The 2067/2068 has 120 volt AC run to the Rough-in, so AC power for the new rough-in is already there. |
| Procedure for stereo speaker | To achieve true stereo music, you will need to extend your speaker wires to the nearest open location. There they will be connected to the MC960PA stereo amplifier. The MC960PA can be mounted in the basement or a closet and connect to the DMC3-4 via the MS7XSC cable. | |
N2027 Speaker | DMC3R | The DMC3R is used with the DMCFR to attach to the current metal rough-in frame and cover the old hole. It makes a very easy and quick change out. |
2021 Inside Speaker | IS-79MOD | The IS-79 is a speaker that can be painted to match your room.
It comes with a volume control (not shown) for music only. It will mount to
your existing metal frame If intercom is desired, you would need to use the DMC3R with the DMC1HR frame and do some wall patching. |
412 Door Speaker | DB3 door speaker with DMCFD frame | The DMCFD update frame mounts to the existing metal frame for easy installation. |
2006 Door Speaker | DB3 door speaker with DMCFD frame | The DMCFD update frame mounts to the existing metal frame for easy installation |
2014 Outside controls | DMC3RW outdoor speaker with DMCFRW | M & S does not make a control only, so you can replace the control with the DMC3RW speaker with the DMCFRW update frame. |
2014 Outside Speaker | IS-79 mod | The 2014 and the IS-79 are similar in appearance. They both have a metal grill. The old 2014 is 1 " larger than the IS-79 but the new IS-79 should mount in the old rough-in. |
