a. Select an appropriate mounting location which
provides both adequate support and sufficient clearance
for the speaker assembly. In addition, the mounting location
should provide maximum signaling effectiveness while
minimizing the sound reaching the vehicle's occupants.
b. Attach the supplied bracket to the speaker using
the 5/16-18x3/4'' bolts and split lockwashers as shown in
figure 1. Do not tighten the bolts at this time.
WARNING
To avoid reduction of sound output and damage
to the speaker, ensure that the speaker is mounted with
the wires exiting from the right side of the speaker when
looking at it from the front.
c. If necessary, remove the bracket from the
speaker. Using the bracket as a template, scribe four drill
positioning marks at the selected mounting location.
CAUTION
Before drilling holes in ANY part of a vehicle, be
sure that both sides of the mounting surface are clear
of parts that could be damaged; such as brake lines,
fuel lines, electrical wiring or other vital parts.
d. Drill 3/16'' mounting holes at the position marks.
Some mounting arrangements may require
installing the bracket on the mounting surface before
securing the speaker to the bracket.
e. Secure the bracket, or assembled unit, unit to
the mounting surface using the 1/4''x5/8'' type B screws
and 1/4'' lockwashers as shown in figure 1. Position the
front of the speaker perpendicular to a horizontal mounting
surface or parallel to a vertical mounting surface, and
secure the speaker to the bracket with the 5/16-18x3/4''
bolts.
f. Connect the two leads from the speaker to the
electronic siren's speaker cable. When two speakers are
used, it is necessary to connect them in phase. This can
be accomplished by connecting the two ''red'' speaker
leads to one lead of the siren's speaker cable, and the two
''black'' speaker leads to the other siren speaker cable
lead. Refer to the instructions packed with the electronic
siren for additional details.
WARNING
All effective sirens produce loud sounds which
may cause, in certain situations, permanent hearing
loss. You should take appropriate precautions such as
wearing hearing protection.
g. Test the speaker(s) for proper operation.
