Safety Messages to Installers of Federal Signal
Sound/Light Systems
People’s lives depend on your proper installation and servicing of Federal Signal products. It is important
to read and follow all instructions shipped with this product. In addition, listed below are some other
important safety instructions and precautions you should follow:
Before Installation
Qualications
• To properly install an electronic siren, you must have a good understanding of automotive electrical
procedures and systems, along with prociency 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 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.
• Federal Signal siren ampliers 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.

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 components is complete, and you have veried 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 amplier 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. 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.
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to be
recalibrated for proper air bag deployment.
• 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.

After Installation
• After installation, test the emergency warning 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 or reinstalling the product.
Failure to follow all safety precautions and instructions may result in property damage,
serious injury, or death.

Safety Messages to Operators of Federal Signal
Sound/Light Systems
People’s lives depend on your safe operation of Federal Signal 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:
• Do not attempt to activate or de-activate the controls of the emergency warning system while driving
in a hazardous situation.
• Although your warning system is operating properly, it may not be completely effective. People
may not see, hear, or heed your warning signal. You must recognize this fact and continue driving
cautiously.
• Also, situations may occur which obstruct your warning signal when natural and man-made objects
are between your vehicle and others, such as raising your hood or trunk lid. If these situations occur,
be especially careful.
• All effective sirens and horns produce loud sounds that may cause, in certain situations, permanent
hearing loss. You and your passengers should consider taking appropriate safety precautions, such as
wearing hearing protection.
• The effectiveness of an interior mounted warning light depends on the clarity, the tinting, and the
angle of the glass it is being placed behind. Tinting, dirt, defects, and steeply angled glass reduce the
light output of the warning light. This may reduce the effectiveness of the light as a warning signal. If
your vehicle has dirty, tinted, or steeply angled glass, use extra caution when driving your vehicle or
blocking the right of way with your vehicle.
• In order to be an effective warning device, this product produces bright light that can be hazardous to
your eyesight when viewed at a close range. Do not stare directly into this lighting product at a close
range or permanent damage to your eyesight may occur.

• It is important that you fully understand how to safely operate this warning system before use.
• You should only operate your vehicle and its light/sound system in accordance with your
department’s Standard Operating Procedures.
• If a selected function does not perform properly or if any of the lamps remain illuminated when the
control is off, disconnect the power connector from the control unit and contact the nearest service
center.
• At the start of your shift, you should ensure that the entire warning light system and the siren system
is securely attached and operating properly.
• Suction cup mounting is for temporary applications only. The unit should be removed from the
window and stored securely when not in use. Temperature changes and sunlight can cause suction
cups to lose holding power. Periodically check the unit to be sure the suction cups have a rm grip
on the mounting surface. An improperly secured light could fall off of the vehicle causing injury and
damage.
• The holding power of magnetic mounting systems is dependent upon surface nish, surface atness,
and thickness of the steel mounting surface. Therefore, to promote proper magnetic mounting:
✓ Mounting surface and magnets must be kept clean, dry, and free of foreign particles that
prevent good surface contact.
✓ Ensure that mounting surface is at.
✓ A magnet mounting system should not be used on vehicles with vinyl tops.
✓ To prevent sliding of light assembly on mounting surface, quick acceleration and hard stops
should be avoided.
Failure to follow these precautions may result in property damage, serious injury, or death.
