WALL HOUSING INSTALLATION
The wall housing mounts between two 16” centered studs
and holds the master unit, optional CD player, chime module,
and power transformer(s).
Determine a location for the wall housing.
Position the back side of the wall housing fl ush with the back of
the 2 x 4 studs with the bottom edge approximately 59” above
the fl oor for the dmc1H wall housing or 52” above the fl oor for the
dmc1HC wall housing. Be sure the rectangular transformer mounting
knockout is on the bottom of the wall housing (see Figure 1).
Attach the wall housing to the studs with wood screws.
If the studs are spaced farther apart than 16”, use wood
shims to make up the difference. ALWAYS SECURE
THE WALL HOUSING ON BOTH SIDES.
If using the Model dmc1H housing, install the four
1-1/2” snap-in bushings into the knockout holes.
TRANSFORMER INSTALLATION
The Model TE5D transformer powers the dmc1 master.
The Model TE2D transformer powers the optional dmc1CD
CD player. Both transformers are supplied in a small metal
enclosures that mount to the bottom of the wall housing.
Run a 14 AWG 120 VAC power cable (including ground)
from a dedicated 15-amp circuit breaker to the wall housing
location. The dmc1 requires a dedicated power source
to assure there’s no interference from other equipment.
The ground is required for good radio reception.
Slide the transformer enclosure(s) down into the
rectangular transformer mounting knockout(s) on
the bottom of the wall housing (see Figure 2).
If installing the second transformer for the CD player option,
cut a 1-1/2 foot length of power cable to loop between the
two transformers. Insert an end of the cable into each of the
transformer enclosures through the bottom knockout holes.
Use wire nuts to connect the cable to the TE2D transformer
BLACK (HOT) and WHITE (NEUTRAL) input wires. Connect
the GREEN (GROUND) wire to the cable’s ground conductor.
Route the incoming power cable into the TE5D transformer
enclosure through the bottom knockout hole. Use wire nuts to
connect the incoming power cable to the TE5D transformer BLACK
(HOT) and WHITE (NEUTRAL) input wires (and to the cable
going to the TE2D transformer if installed). Connect the GREEN
(GROUND) wire to the cable(s) ground conductor (see Figure 3).
Be sure all power cables entering the transformer
enclosure(s) are secured with cable strain reliefs.
Tuck the cables into the transformer enclosure(s)
followed by the transformer on its mounting plate.
Secure the transformer(s) and enclosure(s) to the wall
housing with the screws supplied (see Figure 4).
