″ back box
(Fig. 2) as follows:
A. For the 4″×4″, mount the mud plate (provided) using the 8-32
pan head screws. Make sure the mud plate is mounted verti-
cally, as shown.
B. Mount the chime/strobe using the 6-32 oval head screws. The
chime/strobe shall be mounted on the left side of the mud
ring. The 6-32 screws shall be inserted into the holes on the
mud ring that are opposite that of the strobes; i.e., when the
strobe is on the right, screws into the left side of the mud ring,
and vice versa. See Figure 1.
NOTE: Two drywall screws (provided) may be used to fasten the
mounting plate to the wall. To use the drywall screws,
it will be necessary to first unsnap and hinge the strobe

box (Fig. 4) as follows:
A. Mount the BBS-CHS and the mud plate (provided) using the
8-32 pan head screws. Make sure that the large opening in the
BBS-CHS lines up with the horn and the mud plate is mounted
vertically, as shown.
B. Mount the chime/strobe using the 6-32 oval head screws. The
chime/strobe shall be mounted on the left side of the mud
ring. The 6-32 screws shall be inserted into the holes on the
mud ring that are opposite that of the strobes; i.e., when the
strobe is on the right, screws into the left side of the mud ring,
and vice versa. See Figure 1.
To reverse the strobe module: insert screwdriver, as shown in
Fig. 3, to unlock snap. While pushing in the screwdriver, pull
back on the strobe module. Hinge the strobe module, disengage
the Locking Rib and lift the module away from the mounting
plate. Turn the module so that it is upside down from its original
position, re-insert the module into the mounting plate (be sure
to insert the Locking Rib into the slot), and press the module
into the mounting plate. The strobe module will make a “click”
when it has locked into place. Turn the entire assembly so that
the lens/reflector is on the bottom, as shown. The unit can now
be mounted.
