Safety Message to Installers and Service Personnel of Emergency Vehicle Safety
Equipment
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
electrical procedures and systems, along with proficiency in the installation and service of safety warning
equipment. Always refer to the vehicle service manuals when installing equipment on a vehicle.
Electrical Hazards
• 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 and safety functions or circuits.
During Installation or Service
• 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 gasses produced by a battery can
cause a battery explosion that could result in vehicle damage and serious injury.
• Do not install equipment or route wiring or a plug-in cord in the deployment path of an airbag.
• 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 in other areas subject to extreme environmental exposure.
• 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, and grommet all
drilled holes through which wiring passes. Ensure that mounting screws do not cause electrical or
mechanical damage to the vehicle.
After Installation or Service
• To ensure proper operation, test all vehicle functions, including horn operation, vehicle safety functions,
and vehicle light systems. Ensure that installation has not affected vehicle operation or changed any
vehicle safety function or circuit.
• 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 reinstalling the product.
Failure to follow all safety precautions and instructions may result in property damage, serious injury, or
death.
