Product Overview
Federal Signal has combined the superior light output of a rotator with the advantages of LEDs to create the
rst true LED beacon in the marketplace, the IVP SLR.
Featuring the patented Solaris LED Rotator, the IVP SLR creates a burst of illumination with the benets of
a rotator to create a sweep of light unmatched by ashing lights.
The IVP VSLR is available in two styles that compliment Federal Signal’s Vision SLR lightbars. The VSLR1
features red or amber LEDs and may be used as part of an NFPA lighting package. The VSLR1-IPX-RA is
NFPA compliant and features a red LED rotator and an Impaxx Model IPX600 light in an attractive housing.
Driver-side (VSLR1D) and passenger-side (VSLR1P) oscillating models are also available. They are
designed to be mounted on the rear of a re apparatus. When oscillating, the lights emit light in the areas
shown in Figure 1 on page 2.

7. Install one or two mounting pads over each of the three mounting studs as shown in Figure 1.
8. Position the light over the mounting holes and route the cable through the grommet. For the VSLR1-IPX,
allow 10" to 18" of slack in the cable under the roof so the unit can be removed if the Impaxx is damaged
and needs replacement.
9. To prevent water leakage if applicable, apply a silicone sealing compound around the cable and
grommet where they pass through the mounting surface.
10. Secure the unit to the mounting surface with the three 1/4"-20 elastic stop nuts.
Wiring the Light in the Vehicle
The light is completely wired at the factory and does not require any additional internal wiring. All the
conductors necessary for control of light assembly are contained in the leads. The basic light functions of
the unit must be controlled by a installer-supplied control head. Before proceeding, ensure that the light
assembly has been installed on the vehicle roof in accordance with the instructions
LOCATION OF LIGHT SYSTEM CONTROLS—Locate the light system controls so the
VEHICLE and CONTROLS can be operated safely under all driving conditions.
To wire the light assembly:
1. Determine the length of wires needed for the installation. For lengths up to 15 ft (5 m), use minimum
18 AWG (1 mm2) wire. For lengths over 15 ft, use minimum 16 AWG (1.5 mm2) wire.
Use insulated butt connectors to splice the leads. Ensure that the connectors are securely crimped and
properly insulated.
2. See Figure 3 on page 5. Connect the black lead to chassis ground (–NEG).
3. Connect the red wire (+BAT) to one terminal of an installer-supplied switch with a current capacity of at
least 8 A.
4. Connect the other terminal of the switch through an installer-supplied 8 A fuseholder to the positive
(+BAT) terminal of the voltage source.

Cleaning the Plastic Dome
CRAZING/CLEANING SOLUTIONS—The use of other materials such as strong
detergents, solvents, petroleum products, etc. can cause crazing (cracking) of the
plastic domes. If crazing of domes does occur, reliability of light for emergency
purposes may be reduced until domes are replaced. Failure to follow this warning
can damage the domes, reducing the effectiveness of the lighting system, and may
result in injury or death.
CRAZING/CHEMICALS—Crazed, cracked or faded domes reduce the light output and
the effectiveness of the lighting system. Domes or reectors showing this type of
aging must be replaced. Failure to follow this warning may result in injury or death.
To clean the dome:
1. Rinse the dome with lukewarm water to loosen dirt and debris.
2. Use a mild detergent, lukewarm water, and a soft cloth to gently clean the dome. To avoid damaging the
nish, do not use heavy pressure or caustic, abrasive, or petroleum-based cleaners.
3. Rinse and dry the dome with a soft cloth to prevent water spotting.
4. To remove ne scratches and haze, use a soft cloth and a high quality automotive paste cleaner/wax that
is non-abrasive or a plastic polish like Plexus®
