(CT).
Safety Message to Installers and Service Personnel of Warning Lights
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.
Listed below are some other important safety instructions and precautions you should
follow.
Before Installation or Service
Qualifications
• To properly install or service this equipment, you must have a good understanding
of automotive mechanical and electrical procedures and systems, along with
proficiency in the installation and service of safety warning equipment. Always
refer to the vehicle service manuals when performing equipment installations on a
vehicle.
Light Hazards
• To be an eective 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.
• Do not install the light system in an area that would block, impair, or blind the
driver’s vision. Ensure that the light system is mounted in a position that is outside
of the driver’s field of vision, so the driver can safely operate the vehicle.
• Federal Signal power supplies and light heads are designed to work together as
a system. Combining light heads and a power supply from dierent manufacturers
may reduce the warning eectiveness of the lighting system and may damage
the components. Verify or test your combination to ensure that the system works
together and meets federal, state, and local standards or guidelines.
Electrical Hazards
• Strobe systems present a shock hazard because they use high voltage to operate.
Do not handle strobe cables, the power supply, or bulbs or remove the lens while
the equipment is connected. Strobe systems can also hold their charge even after
they have been turned o. After disconnecting power to the unit, wait five minutes
before handling any parts of the strobe system.

Installation, Maintenance, and Service Manual
Federal Signal www.fedsig.com
Safety Messages
• A light system is a high current system. In order for the system to function
properly, a separate negative (–) connection and positive (+) connection must
be made. All negative connections should be connected to the negative battery
terminal and a suitable fuse should be installed on the positive battery terminal
connection as close to the battery as possible. Ensure that all wires and fuses are
rated correctly to handle the device and system amperage requirements.
• Never attempt to install aftermarket equipment that connects to the vehicle wiring
without reviewing a vehicle wiring diagram available from the vehicle manufacturer.
Ensure that your installation will not aect vehicle operation or mandated
safety functions or circuits. Always check the vehicle for proper operation after
installation.
• The lighting system components, especially light bulbs, strobe tubes, LEDs, and
the outer housing, get hot during operation. Be sure to disconnect power to the
system and allow the system to cool down before handling any components of the
system.
• Halogen light bulbs and strobe tubes are pressurized and, if broken, can burst and
result in flying glass. Always wear gloves and eye protection when handling these
components.
• Do not mount a radio antenna within 18 inches (45.7 cm) of the lighting system.
Placing the antenna too close to the lighting system could cause the lighting
system to malfunction or be damaged by strong radio fields. Mounting the
antenna too close to the lighting system may also cause the radio noise emitted
from the lighting system to interfere with the reception of the radio transmitter and
reduce radio reception.
• Do not attempt to wash any unsealed electrical device while it is connected to its
power source.
During Installation and Service
• 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. Inspect the unit after mounting to be sure there are
no shavings present in or near the unit.
• To avoid a battery explosion, always disconnect the negative battery cable first
and reconnect it last. Avoid causing a spark when connecting near or to the
battery. The gases produced by a battery can caused a battery explosion that
could result in vehicle damage and serious injury.
• 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 the wiring is shorted to the vehicle body or frame,
high current conductors can cause hazardous sparks resulting in electrical fires or
flying molten metal.
• DO NOT install equipment or route wiring (or the plug in cord) in the deployment
path of an airbag.

Federal Signal www.fedsig.com
Safety Messages
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the
seat needs to be recalibrated for proper airbag deployment.
• Before mounting any components, check the manual to be sure that the
component you are installing is suitable for use in that area of the vehicle. Many
components are not suitable for use in the engine compartment or other extreme
environmental exposure areas.
• The service life of light bulbs and strobes tubes will be shortened if the
glass portion is touched during installation. Use gloves when handling these
components. If the glass portion has been touched, clean the glass carefully with
isopropyl alcohol.
• When drilling into a vehicle structure, ensure that both sides of the surface are
clear of anything that could be damaged. Remove all burrs from drilled holes. To
prevent electrical shorts, grommet all drilled holes through which wiring passes.
Also, ensure that the mounting screws do not cause electrical or mechanical
damage to the vehicle.
• Refer to the manual packed with the lighting system for proper electrical
connections, additional precautions, and information.
• Because vehicle roof construction and driving conditions vary, do not drive a
vehicle with a magnetically mounted warning light installed. The light could fly
o the vehicle, causing injury or damage. Repair of damage incurred because of
ignoring this warning shall be the sole responsibility of the user.
• To avoid denting the roof of the vehicle, place the light bar mounting feet as close
to the outer edge of the roof as possible.
• Roof damage can occur if the hook adjustment bolts are overtightened. Tighten
the adjustment bolts to 6 ft-lb to 7 ft-lb. Install keeper plates.
• Locate the light system controls so the VEHICLE and CONTROLS can be operated
safely under all driving conditions.
After Installation or Service
• After installation, test the light system to ensure that it is operating properly.
• To ensure proper operation, test all vehicle functions, including horn operation,
vehicle safety functions, and vehicle light systems. Ensure that the installation
has not aected the vehicle operation or changed any vehicle safety function or
circuit.
• Scratched or dull reflectors, mirrors, or lenses will reduce the eectiveness of
the lighting system. Avoid heavy pressure and use of caustic or petroleum-based
products when cleaning the lighting system. Replace any optical components that
may have been scratched or crazed during system installation.
• Do not attempt to activate or deactivate the light system control while driving in a
hazardous situation.
• Frequently inspect the light system to ensure that it is operating properly and that
it is securely attached to the vehicle.

Safety Message to Operators of Warning Light Equipment
People’s lives depend on your safe use of our products. Listed below are some
important safety instructions and precautions you should follow:
• Do not attempt to activate or deactivate the light system control while driving in a
hazardous situation.
• Although your warning system is operating properly, it may not be completely
eective. People may not see or heed your warning signal. You must recognize
this fact and continue to drive cautiously.
• Situations may occur that 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.
• The eectiveness 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 eectiveness 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.
• All eective 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.
• In order to be an eective 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.
• 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 o, disconnect the power connector from the control
unit and contact the nearest service center.
• At the start of your shift, ensure that the entire warning light system and the siren
system is securely attached and operating properly.

Safety Messages
• 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 firm grip on the mounting
surface. An improperly secured light could fall o of the vehicle, causing injury and
damage.
• Holding power of magnetic mounting systems is dependent upon surface finish,
surface flatness, and thickness of the steel mounting surface. Therefore, to
promote proper magnetic mounting:
• Keep the mounting surface and magnets clean, dry, and free of foreign particles
that prevent good surface contact.
• Ensure that mounting surface is flat.
• Do not use a magnet mounting system on vehicles with vinyl tops.
• To prevent sliding of light assembly on mounting surface, avoid quick
acceleration and hard stops.
Failure to follow these precautions may result in property damage, serious injury, or
death.
