d. Drill 3/16” mounting holes at the position marks.
NOTE
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 to the
mounting surface using the 1/4” x 5/8” type B screws and 1/4”
lockwashers as shown in figure 1 or 2. Position the front of the
speaker perpendicular to a horizontal mounting surface or paral-
lel to a vertical mounting surface, and secure the speaker to the
bracket with the 5/16-18 x 3/4” bolts.
f. Connect the two leads from the speaker to the elec-
tronic 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.
All effective sirens and horns produce loud
sounds (120 dB) that may cause permanent hear-
ing loss. Always minimize your exposure to siren
sound and wear hearing protection. Do not sound
the siren indoors or in enclosed areas where you
and others will be exposed to the sound.
g. Test the system for proper operation.
