appropriate power post. When connecting this plug,
make sure the black wire is connected to the COM post
and the red wire to the numbered post.
NOTE
: The plug MUST be installed for the speaker to oper-
ate. The speaker cannot sound or produce a trouble
indication at the panel if the plug is not installed.
Mounting
NOTE
: The descriptions in this section assume that all prepa-
rations necessary for the installation of the speakers
have been completed. This includes the installation
of all conduit, electrical boxes, and wiring.
A. General
Both slotted head and phillips head screws are supplied
with the speaker/strobe. Use the slotted head screws to
mount the device or combination of devices on the electri-
cal box. Use the phillips head screws in the two remaining
holes when only a speaker is being installed.
B. Surface Mount
1. Speaker Only (Figure 2)
(a) Wire the speaker as described in Electrical.
(b) Attach the speaker to a standard 4-inch electrical
box, using the two 8-32 X 1

slotted screws pro-
vided. Fill the remaining holes with the short #8
sheet metal screws.
2. Speaker with Strobe ( Figure 3)
(a) Use a small bladed screwdriver to remove the plastic
flash from the two strobe lug slots on the speaker.
(b) Identify the two diagonally opposite speaker holes
that will be needed for mounting the speaker on the
electrical box. The other two holes will be used to
attach the strobe and flush mount plate to the
speaker.
(c) Position the strobe over the speaker and guide its
two power lugs into the slots formed when the flash
was removed in step 2(a). Attach the strobe and
flush mount plate to the speaker using #8 phillips
head sheet metal screws through the pair of strobe
mounting holes that was selected in step 2(b).
(e) Slide the right angle connector on the red wire onto
the strobe power lug nearest the “F” in “FIRE”. Simi-
larly, connect the right angle connector on the black
wire to the remaining lug on the opposite side of the
speaker.
(f) Connect the free end of the red wire to the STROBE
+ terminal (1) and black wire to STROBE – (5).
Then, connect a source of uncoded (continuous) 12
VDC or 24 VDC, as appropriate for the strobe model,
to the and STROBE – terminals (1 and 5,
respectively). Be sure to observe polarity.
(g) Wire the speaker as described in Electrical and at-
tach it to the box, using two 8-32 X 1
