INSTALLATION INSTRUCTIONS
FOR
MS100-DEU SPEAKER
SAFETY MESSAGE TO INSTALLERS OF SIREN SPEAKERS
The lives of people depend on your proper installa-
tion and servicing of Federal 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
Qualifications
•
To properly install an electronic siren: 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 equip-
ment 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 horns produce loud sounds
(120dB) that may cause permanent hearing loss. Always
minimize your exposure to siren sound and wear hear-
ing protection. Do not sound the siren indoors or in en-
closed areas where you and others will be exposed to the
sound.
•
Federal Signal siren amplifiers and speakers are de-
signed 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.
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 ap-
proved 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 components 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 in-
stallation have compatible wattage ratings.
•
In order for the electronic siren to function properly, the
ground connection must be made to the NEGATIVE bat-
tery terminal.
•
Sound output will be severely reduced if any objects are
in front of the speaker. If maximum sound output is re-
quired 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 signal-
ing 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 sys-
tem. 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 vehi-
cle wiring diagram - available from the vehicle manufac-
turer. 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 mi-
crophone 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 ensure that it is operating properly.
•
Test all vehicle functions, including horn operation,
vehicle safety functions and vehicle light systems, to en-
sure 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 in-
structions 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.
