SAFETY MESSAGE TO INSTALLERS AND USERS
People’s lives depend on your safe installation of our products. It
is important to read, understand and follow all instructions shipped
with the products. In addition, listed below are some other important
safety instructions and precautions you should follow:
• To properly install this light: you must have a good
understanding of automotive electrical procedures and
systems, along with proficiency in the installation and
use of safety warning equipment.
• DO NOT install equipment or route wiring in the
deployment path of an air bag.
• When drilling into a vehicle structure, be sure that both
sides of the surface are clear of anything that could be
damaged.
• In order 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 will provide an effective ground path
as long as the light system is to be used.
• Locate light control so the VEHICLE and CONTROL
can be operated safely under all driving conditions.
• Do not attempt to activate or deactivate light control
while driving in a hazardous situation.
• You should frequently inspect the light to ensure that it
is operating properly and that it is securely attached to
the vehicle.
• 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 to you or others.
A. GENERAL.
The Model GS5 is a high-intensity strobe head designed for flush
mounting on a vehicle’s exterior. It is designed for use with the Federal
Model SPS8 strobe power supply. The Model SPS8 is an eight head
power supply rated at 75 quadruple flashes per minute and provides
the following options: fast flash pattern, primary, secondary, and
reduced power mode.
B. INSTALLATION.
WARNING
This product is intended for use in a primary warning light
system. The strobe heads can ONLY be powered by the Model
SPS8 power supply. Consult local codes and regulations to
determine if the power supply/strobe head combination
complies.
NOTE
For maximum coverage and effectiveness, the light assembly
should be mounted in a horizontal orientation in pairs: one in
front and one to the side.
1. Determine the desired mounting location. Using the flange,
scribe drill position marks on the mounting surface for the 4mm

mounting bolts. A 5-7/16" x 3-11/16" rectangular hole is required for
clearance. Center the rectangular hole between the mounting holes.
CAUTION
Before drilling or cutting holes in ANY part of the vehicle, be
sure that both sides of the mounting surface are clear of
parts that could be damaged; such as brake lines, fuel lines,
electrical wiring or other vital parts.
2. Drill four mounting holes in the mounting surface. Cut the
clearance hole.
3. Secure the light assembly to the mounting surface using the
supplied hardware as shown in figure 1.
C. ELECTRICAL CONNECTIONS.
CAUTION
The flush mount strobe light assembly is designed to be used
exclusively with Federal Signal’s Model SPS8 power supply.
Use of any other power supply may cause shortened service
life of the strobe tube.
The flush mount strobe light assembly is supplied with a
connector attached to the strobe tube assembly. The supplied mounting
kit includes two separate connectors and pins. One connector is the
mating end of the connector supplied with the strobe tube assembly.
The other connector is to be used on the user-supplied cable and mates
with the connectors on a Federal Signal strobe power supply.
Locate the light assembly’s mating connector and pins. Route
the user-supplied cable into the light through the rubber grommet on
the rear of the housing. Crimp the supplied pins on the user-supplied
cable. See figure 2. Insert the pins in the connector housing supplied in
the kit and push until they snap into place. The connector can now be
plugged directly into the flush mount strobe light assembly. The other
end of the user-supplied cable connects to Federal’s strobe power supply
and uses the other connector and pins. Observe proper wire colors and
placement when making connections as shown in figure 2.

D. MAINTENANCE.
1. General.
WARNING
Crazing (cracking) of lenses will cause reduced effectiveness
of the light. Do not use cleaning agents (which will cause
crazing) such as strong detergents, solvents, or petroleum
products. If crazing of lenses does occur, reliability of light for
emergency signaling purposes may be reduced until lenses
are replaced.
Ordinary cleaning of the plastic lenses can be accomplished
by using mild soap and a soft rag. Should fine scratches or a haze
appear on a lens, they can ordinarily be removed with a non-abrasive,
high quality, one-step, automotive paste cleaner/wax and a soft cloth.
2. Strobe Tube Assembly Replacement.
WARNING
High voltage are present in a strobe light system. Wait at
least five (5) minutes, after shutting off power, before
servicing the unit. Failure to do so may result in property
damage, serious injury, or death to you and others.
a. Disconnect all power to the strobe system power supply
before performing any maintenance.
b. See figure 3. Remove and retain the four screws which
secure the trim ring and lens. Carefully pull the trim ring and lens
straight away from the flush mount light assembly.
c. Remove the three screws which secure the strobe tube
reflector. Remove the strobe tube reflector by pulling it straight away.
d. Remove the four screws which secure the strobe
assembly mounting brackets.
e. Disconnect the strobe tube reflector assembly from the
cable assembly.
CAUTION
Service life of strobe tube will be shortened if glass is
touched. If glass has been handled, clean carefully with a
grease solvent.
f. Install the strobe assembly mounting brackets using
the previously removed screws.
