Attach the supplied bracket to the speaker

using the 1/4-20 x 5/8" bolts, washers, and split lockwashers

as shown in figure 2. Do not tighten the bolts at this time.

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.

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.

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.

Secure the bracket, or assembled unit, unit to

the mounting surface using the 1/4" x 5/8" 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 5/16-18 x 3/4"

bolts.

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.

All effective sirens and horns produce loud sounds

(120 dB) that may cause permanent hearing 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.

Test the system for proper operation.
