INSTALLING THE WALL HOUSING

The DMC1H and DMC1HC housings are designed for 16”

on center studs. You may encounter stud spacings that vary

from this standard.

• Use the DMC1H housing when you are replacing an

existing system with an intercom only system.

• The DMC1HC housing is used for combination

systems only – or those that include the DMC3-4

master and the optional DMCMP3 CD/MP3 player.

Locate the DMC1H or DMC1HC (combo) wall housing

between the studs (see Figures 2 & 3). The housing must

be positioned so that the transformer knockout(s) are on the

bottom of the wall housing as shown.

If you are replacing the existing master only system with a

combination DMC3-4 system with the CD/MP3 player, you

will have to cut the rough-in opening larger to accommodate

the larger wall housing. Prior to making the cutout check

the stud cavity for obstructions or items in the wall that may

prevent the transformers from ﬁ tting in the wall.

1. 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

(52” above the ﬂ oor for DMC1HC). Be sure the rectangular transformer

mounting knockout(s) are on the bottom of the wall housing.

2. 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.

3. On the DMC1H, install the four 1-1/2” snap-in bushings into the round

knockout holes.
