Safety Message to Installers of Siren Speakers
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 prod-
ucts. In addition, listed below are some other important
safety instructions and precautions you should follow:
Before Installation
Qualifications
• To properly install an electronic speaker: you must have a
good understanding of automotive electrical procedures and
systems, along with proficiency 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 con-
servation guidance, refer to federal, state, or local recommen-
dations. OSHA Standard 1910.95 offers guidance on “Permis-
sible 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 amplifiers and speakers are designed to
work together as a system. Combining a siren and speaker
from different manufacturers may reduce the warning effective-
ness 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.
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 verified that no shorts exist. If
wiring is shorted to vehicle frame, high current conductors can
cause hazardous sparks resulting in electrical fires or flying
molten metal.
•
Be sure the siren amplifier 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.
• Sound output will be severely reduced if any objects are in front
of the speaker. If maximum sound output is required for your
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. Re-
fer 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 op-
erators 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 con-
nects 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 deploy-
ment path of an air bag.
• Locate the control head so the vehicle, controls, and micro-
phone 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.
After Installation
• After installation, test the siren system and light system to en-
sure that it is operating properly.
• Test all vehicle functions, including horn operation, vehicle
safety functions and vehicle light systems, to ensure proper op-
eration. Ensure that installation has not affected vehicle opera-
tion 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 instruc-
tions may result in property damage, serious injury, or
death to you or others.
