Safety Message to Installers of Siren Speakers
• Sound output will be severely reduced if any objects are in front
of the speaker. If maximum sound output is required for your
The lives of people depend on your proper installation
and servicing of Code 3®, Inc. products. It is important
to read and follow all instructions shipped with the products. In addition, listed below are some other important
safety instructions and precautions you should follow:
Before Installation
Qualications
• To properly install an electronic speaker: you must have a
good understanding of automotive electrical procedures and
systems, along with prociency in the installation and service
of safety warning equipment. Always refer to the vehicle’s
service manuals when performing equipment installations on
a vehicle.
Sound Hazards
• Your hearing and the hearing of others, in or close to your
emergency vehicle, could be damaged by loud sounds. This
can occur from short exposures to very loud sounds, or from
longer exposures to moderately loud sounds. For hearing conservation guidance, refer to federal, state, or local recommendations. OSHA Standard 1910.95 offers guidance on “Permissible Noise Exposure.”
• All effective sirens and speakers 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.
• Code 3®, Inc siren ampliers and speakers are designed to
work together as a system. Combining a siren and speaker
from different manufacturers may reduce the warning effectiveness of the siren system and may damage the components.
You should verify or test your combination to make sure the
system works together properly and meets federal, state and
local standards or guidelines.
application, you should ensure that the front of the speaker is
clear of any obstructions.
• Install the speaker(s) as far forward on the vehicle as possible,
in a location which provides maximum signaling effectiveness
and minimizes the sound reaching the vehicle’s occupants. Refer to the National Institute of Justice guide 500-00 for further
information.
• Mounting the speakers behind the grille will reduce the sound
output and warning effectiveness of the siren system. Before
mounting speakers behind the grille, make sure the vehicle operators are trained and understand that this type of installation
is less effective for warning others.
• Sound propagation and warning effectiveness will be severely
reduced if the speaker is not facing forward. Carefully follow the
installation instructions and always install the speaker with the
projector facing forward.
• DO NOT install the speaker(s ) or route the speaker wires where
they may interfere with the operation of air bag sensors.
• Installation of two speakers requires wiring speakers in phase.
• Never attempt to install aftermarket equipment, which connects to the vehicle wiring, without reviewing a vehicle wiring
diagram - available from the vehicle manufacturer. Insure that
your installation will not affect vehicle operation and safety
functions or circuits. Always check vehicle for proper operation
after installation.
• DO NOT install equipment or route wiring or cord in the deployment path of an air bag.
• Locate the control head so the vehicle, controls, and microphone can be operated safely.
• When drilling into a vehicle structure, be sure that both sides of
the surface are clear of anything that could be damaged.
During Installation
• DO NOT get metal shavings inside the product. Metal shavings
in the product can cause the system to fail. If drilling must be
done near the unit, place an ESD approved cover over the unit
to prevent metal shavings from entering the unit. Inspect the
unit after mounting to be sure there are no shavings present
in or near the unit.
• DO NOT connect this system to the vehicle battery until ALL
other electrical connections are made, mounting of all compo-
nents is complete, and you have veried that no shorts exist. If
wiring is shorted to vehicle frame, high current conductors can
cause hazardous sparks resulting in electrical res or ying
molten metal.
• Be sure the siren amplier and speaker(s) in your installation
have compatible wattage ratings.
• In order for the electronic siren to function properly, the ground
connection must be made to the NEGATIVE battery terminal.
After Installation
• After installation, test the siren system and light system to ensure that it is operating properly.
• Test all vehicle functions, including horn operation, vehicle
safety functions and vehicle light systems, to ensure proper operation. Ensure that installation has not affected vehicle operation or changed any vehicle safety function or circuit.
• After testing is complete, provide a copy of these instructions to
the instructional staff and all operating personnel.
• File these instructions in a safe place and refer to them when
maintaining and/or reinstalling the product.
Failure to follow all safety precautions and instructions may result in property damage, serious injury, or
death to you or others.

Unpacking & Pre-Installation
A. UNPACKING
C. BAIL BRACKET MOUNTING
After unpacking the kit, carefully check all envelopes, shipping labels, and tags before removing or destroying them. Ensure that the parts listed in the KIT
CONTENTS LIST are contained in the packing carton.
B. INSTALLATION
To avoid reduction of sound output and damage to speaker, ensure that speaker is mounted with wires protruding from the bottom of
the speaker when viewing it from the front.
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. Note that the two rear bracket hole
locations MUST be protected during the drilling
operation.
a. Select an appropriate mounting location which
provides both adequate support and sufcient clearance for
the speaker assembly. In addition, the mounting location
should provide maximum signaling effectiveness while minimizing the sound reaching the vehicle’s occupants.
To avoid reduction of sound output, ensure
that the speaker is mounted with the sound opening
facing directly in the direction intended to warn.
NOTE
Because of the variety of vehicles and possible
mounting arrangements, installation details and
mounting bracket fabrication must be determined by the installer.
1. General
The supplied bracket is designed for mounting directly
on a surface which has been determined to be suitable for speaker
installation. In addition, it may be used to install the speaker on an
adapter bracket fabricated by the installer.
The bracket has two sets of speaker mounting holes.
Use the outer pair of holes when mounting on a horizontal surface.
Use the inner pair of holes when mounting on a vertical surface.
When using the inner pair of holes (vertical surface mounting),
space restrictions may require removal of the excess bracket material that protrudes in front of the speaker.
NOTE
Because of the variety of vehicles and possible mounting
arrangements, installation details and mounting bracket
fabrication must be determined by the installer.
a. Select an appropriate mounting location which provides both adequate support and sufcient 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
1/4-20 x 5/8” bolts, washers, and split lockwashers as shown in
gure 1 (vertical) or gure 2 (horizontal). 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.
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.
b. See gure 1. After speaker mounting is completed, connect the two leads from the speaker to the electronic siren’s speaker cable. Refer to the instruction sheet
packed with the electronic siren for additional details.
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.
c. Test the system for proper operation.
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.
