Safety Message to Installers and Service Personnel
of Warning Light Equipment
People’s lives depend on your proper installation and servicing of Fed-
eral 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 or Service
Qualications
• To properly install or service this equipment, you must have a
good understanding of automotive mechanical and electrical pro-
cedures 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.
Light Hazards
• 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.
• 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 mount-
ed in a position that is outside of the driver’s eld 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 lightheads and a power
supply from different manufacturers may reduce the warning
effectiveness of the lighting system and may damage the compo-
nents. You should verify or test your combination to ensure the
system works together and meets federal, state and local standards
or guidelines.

SLR LED Rotating Beacon
Electrical Hazards
• Strobe systems present a shock hazard because they use high
voltage to operate. Do not handle strobe cables, the power sup-
ply or bulbs or remove the lens while the equipment is connected.
Strobe systems can also hold their charge even after they have
been turned off. After disconnecting power to the unit, wait ve
minutes before handling any parts of the strobe system.
• A light system is a high current system. For the system to function
properly, a separate negative (–) connection and positive (+) con-
nection must be made. All negative connections should be con-
nected 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 avail-
able from the vehicle manufacturer. Ensure that your installation
will not affect vehicle operation or mandated safety functions or
circuits. Always check the vehicle for proper operation after instal-
lation.
• 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.
• Do not mount a radio antenna within 18 inches (45.7 cm) of the
lighting system. Placing the antenna too close to the lighting sys-
tem could cause the lighting system to malfunction or be damaged
by strong radio elds. Mounting the antenna too close to the light-
ing system may also cause the radio noise emitted from the light-
ing 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.
7
SLR LED Rotating Beacon
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.
• 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 veried 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 res or ying molten
metal.
• DO NOT install equipment or route wiring (or the plug-in cord) in
the deployment path of an airbag.
• 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.
• Before drilling into a vehicle structure, be sure 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 y off the vehicle causing injury or dam-
8
SLR LED Rotating Beacon
age. Repair of damage incurred because of ignoring this warning
shall be the sole responsibility of the user.
• Locate the light system controls so the VEHICLE and CON-
TROLS 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.
• Test all vehicle functions, including horn operation, vehicle safety
functions and vehicle light systems, to ensure proper operation.
Ensure that the installation has not affected the vehicle operation
or changed any vehicle safety function or circuit.
• Scratched or dull reectors, mirrors or lenses will reduce the ef-
fectiveness of the lighting system. Avoid heavy pressure and use
of caustic or petroleum based products when cleaning the light-
ing system. Replace any optical components that may have been
scratched or crazed during system installation.
• Do not attempt to activate or de-activate the light system controls
while driving in a hazardous situation.
• You should frequently inspect the light system to ensure that it is
operating properly and that it is securely attached to the vehicle.
• After installation and testing are complete, provide a copy of these
instructions to instructional staff and all operating personnel.
• File these instructions in a safe place and refer to them when
maintaining and/or re-installing the product.
Failure to follow all safety precautions and instructions may result in
property damage, serious injury, or death.
