Table 1. Power Tap Setting vs. Sound Output.
The speaker can be mounted on any relatively flat
surface. Conduit connection can be made to two 1/2"
threaded openings at the bottom of the housing or to 7/8"
knockout in rear of housing. A 1/2" conduit plug is supplied
for field installation if one of the 1/2" threaded openings is
not utilized. After the mounting location and mounting
method have been selected, proceed with the applicable
instructions below.
WARNING
Property damage, serious injury, or death could
occur if an accumulation of water, snow, dust, etc.
resides in the speaker projector, severely reducing
or preventing operation of this device. Mount the
unit so speaker projector is pointed horizontally or
slightly downward.
1. Flat Surface Mounting
a. Remove and retain the two screws that
secure cover to housing. Remove the cover.
WARNING
Property damage, serious injury, or death could
occur if any objects are in front of speaker, severely
reducing optimum sound distribution. For maxi-
mum effectiveness, ensure that the front of the
speaker is clear of obstructions.
b. Select the mounting location and place
rear of housing against mounting surface.
c. Using the mounting holes (four (4) in exter-
nal mounting bracket) as a template, scribe drill position
marks on the mounting surface. See figure 1 for mounting
hole locations and dimensions.
CAUTION
Before drilling holes in any surface, ensure that
both sides of surface are clear of items that could
be damaged.
d. Secure the unit to a wooden mounting
surface with #10 x 1" wood screws. If mounting on a metal
surface, drill 13/64" diameter holes and secure the unit with
#10 screws, lockwashers and nuts.
e. Route power and supervision leads through
conduit to the audible signal. Install a 1/2" electrical connec-
tor at the bottom of the audible signal. Route wires through
conduit and electrical connector into the audible signal
housing. Install supplied 1/2" conduit plug if only one 1/2"
conduit entrance is used.
WARNING
Property damage, serious injury or death could
occur if the projector is mishandled during installa-
tion or over time. DO NOT rotate the projector more
than 180 degrees or internal speaker wiring may be
damaged.
f. Reposition speaker projector if necessary
to obtain desired sound coverage. Loosen collar nut (see
figure 1) and move projector to desired position.
g. Before reinstalling the housing cover, read
paragraph III.C. Electrical Connections below and make the
necessary electrical connections.
C. Electrical Connections.
DANGER
To avoid electrical shock, do not connect wires
when circuits are energized.
National Electrical Code as well as local codes
must be adhered to in installation of these models. All
electrical wiring must be routed through approved conduit
and fittings.
1. See figures 2 and 3. Connect the audio com-
mon (-) leads to the speaker’s common terminal and audio
positive (+) leads to desired wattage terminal.
