REPLACING THE ROOM STATIONS

The DMC room and door speakers use the existing wire

and speaker rough-in mounting frames or boxes. To replace

the speaker, ﬁ rst remove the old speaker. Leave the existing

room or door station mounting rings in place.

After removing the room station verify the integrity of the

wire run. Then install the mounting plate from the DMCFR

(ﬁ nish-out frame for room stations). Align the plate on the

wall either vertically or horizontally so that the screw holes

line up with those on the mounting ring or box. Use a level

to make sure the plate is level. There are several screw hole

locations on the mounting plate so it can attach to many

rough-in designs. Mount the plate to the wall using the

screws provided (Figure 7).

Next connect the wires to the retroﬁ t room station as shown

in Figure 8. Match the wire colors to the corresponding

screw locations on the DMC3 or DMC4 room stations.

Please make sure to use only DMC3 room stations in a 3-wire

installation and DMC4 room stations in a 4-wire installation.

All 6-wire, 7-wire, & 8-wire installations use the DMC1

room stations.

Please refer to Appendix A for a table of which NuTone

and M&S Systems retroﬁ t to the 3-wire, 4-wire, or 6-wire

(requires DMC1 master) DMC conﬁ gurations.

After connecting the room station to the existing wiring.

Place the room station through the DMCFR plastic mounting

plate. Position the plate either vertically or horizontally

depending on the room station replaced. Place the room

station into the rough-in ring and align the frame with the

room station as shown in Figure 9. Use the screws provided

with the room station to screw the room station and frame

into place. The holes in the room station align with the holes

in the mounting plate. The room station keeps the plastic

frame in place on the wall.

✔ NOTE: The plastic frames are paintable. Please prime the plastic ﬁ rst

and then apply standard room paint. The white plastic may require two

coats of paint to get full coverage. It is recommended that you paint

the frame prior to mounting it to the wall.

✔ IMPORTANT: Please label all cables at both ends. Incorrectly

connecting cables to the master, room stations or door stations could

result in system damage.
