Installation, Operation, and Service Manual
Federal Signal

• 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 affect 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.
• 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.
• 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 ensure 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.
• 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. 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.
