Safety Message to Installers and Operators 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 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.
• For the light to function properly, a separate ground connection must be made. If practical, it should be
connected to the negative battery terminal. At a minimum, it may be attached to a solid metal body or
chassis part that provides an effective ground path.
• Do not install equipment or route wiring or a plug-in cord in the deployment path of an airbag.
• When 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 mounting screws do not cause electrical or
mechanical damage to the vehicle.
• Locate the light control so the VEHICLE and CONTROL can be operated safely under all driving
conditions.
• This product contains high intensity LED devices. To prevent eye damage, DO NOT stare into the light
beam at close range.
After Installation or Service
• If a vehicle seat is temporarily removed, verify with vehicle manufacturer if the seat needs to be
recalibrated for proper airbag deployment.
• 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, test the lights to ensure that they are operating properly.
