Safety Message to Installers and Service Personnel
Safety Message to Installers and Service Personnel
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 mechanical and electrical procedures and systems, along with proficiency
in the installation and service of safety warning equipment. Always refer to the
vehicle’s service manuals when performing equipment installations on a vehicle.
Light Hazards
• To be an eective warning device, this product produces bright light that can be
hazardous to your eyesight when viewed at a close range. Do not stare directly into
this lighting product at a close range, or permanent damage to your eyesight may
occur.
• Do not install the light system in an area that would block, impair, or blind the driver’s
vision. Ensure that the light system is mounted in a position that is outside of the
driver’s field of vision, so the driver can safely operate the vehicle.
• Federal Signal power supplies and light heads are designed to work together as
a system. Combining light heads and a power supply from dierent manufacturers
may reduce the warning eectiveness of the lighting system and may damage the
components. Verify or test your combination to ensure that the system works together
and meets federal, state, and local standards or guidelines.
Electrical Hazards
• Strobe systems present a shock hazard because they use high voltage to operate.
Do not handle strobe cables, the power supply, or bulbs or remove the lens while
the equipment is connected. Strobe systems can hold their charge even after they
have been turned o. After disconnecting power to the unit, wait five minutes before
handling any parts of the strobe system.
• A light system is a high current system. In order for the system to function properly,
a separate negative (–) connection and positive (+) connection must be made. All
negative connections should be connected to the negative battery terminal and a
suitable fuse should be installed on the positive battery terminal connection as close
to the battery as possible. Ensure that all wires and fuses are rated correctly to handle
the device and system amperage requirements.
• 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 aect vehicle operation or mandated safety
functions or circuits. Always check the vehicle for proper operation after installation.

6SIFMH, SIFMR (Discrete) and SIFMJH,SIFMJR FSJoin™(Serial) Rear ILS Light Bar
Federal Signal www.fedsig.com
Safety Message to Installers and Service Personnel
• The lighting system components, especially light bulbs, strobe tubes, LEDs, and the
outer housing, get hot during operation. 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.
• 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.
• Before mounting any components, check the manual to enure 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.
• Because vehicle roof construction and driving conditions vary, do not drive a vehicle
with a magnetically mounted warning light installed. The light could fly o the vehicle,
causing injury or damage. Repair of damage incurred because of ignoring this
warning shall be the sole responsibility of the user.
• To avoid denting the roof of the vehicle, place the light bar mounting feet as close to
the outer edge of the roof as possible.
• Locate the light system controls so the VEHICLE and CONTROLS can be operated
safely under all driving conditions.

Safety Message to Operators of Warning Light Equipment
People’s lives depend on your safe use of our products. Listed below are some important
safety instructions and precautions you should follow:
• Do not attempt to activate or deactivate the light system control while driving in a
hazardous situation.
• Although your warning system is operating properly, it may not be completely
eective. People may not see or heed your warning signal. You must recognize this
fact and continue to drive cautiously.
• Situations may occur that obstruct your warning signal when natural and man-made
objects are between your vehicle and others, such as raising your hood or trunk lid. If
these situations occur, be especially careful.
• The eectiveness of an interior mounted warning light depends on the clarity, the
tinting, and the angle of the glass it is being placed behind. Tinting, dirt defects, and
steeply angled glass reduce the light output of the warning light. This may reduce the
eectiveness of the light as a warning signal. If your vehicle has dirty, tinted, or steeply
angled glass, use extra caution when driving your vehicle or blocking the right of way
with your vehicle.

permanent hearing loss. You and your passengers should consider taking appropriate
safety precautions, such as wearing hearing protection.
• In order to be an eective warning device, this product produces bright light that can be
hazardous to your eyesight when viewed at a close range. Do not stare directly into this
lighting product at a close range, or permanent damage to your eyesight may occur.
• It is important that you fully understand how to safely operate this warning system
before use.
• Operate your vehicle and its light/sound system in accordance with your department’s

contact the nearest service center.
• At the start of your shift, ensure that the entire warning light system and the siren
system are securely attached and operating properly.
• Suction cup mounting is for temporary applications only. The unit should be removed
from the window and stored securely when not in use. Temperature changes and
sunlight can cause suction cups to lose holding power. Periodically check the unit to
make sure the suction cups have a firm grip on the mounting surface. An improperly
secured light could fall o of the vehicle causing injury and damage.
• The holding power of magnetic mounting systems is dependent upon surface finish,
surface flatness, and thickness of the steel mounting surface. Therefore, to promote
proper magnetic mounting:
• Keep the mounting surface and magnets clean, dry, and free of foreign particles
that prevent good surface contact.
• Ensure that mounting surface is flat.
• DO not use a magnet mounting system on vehicles with vinyl tops.
• To prevent sliding of light assembly on mounting surface, avoid quick acceleration
and hard stops.
Failure to follow these precautions may result in property damage, serious injury,
or death.

Introduction to the SIFM Series SpectraLux
The SIFM SpectraLux ILS is a center-focused, single-level LED light bar that mounts on
the inside of the rear window. It uses ROC (Reliable On Board Circuitry) technology, and
Solaris®S2 reflectors. Deck (SIFMR) and Hatch (SIFMH) models are available. The light bar
operates at a nominal input of 13.6 Vdc (11 Vdc minimum). Both Discrete (SIFMH,SIFMR)
and Serial (SIFMJH, SIFMJR FSJoin™) control are available as configured options
Discrete models have eight control inputs that connect to the user-supplied low current
switches. Serial models are controlled through the CAT5 serial communication cable. The
cable connects to Federal Signal Convergence network controllers, or the Convergence
Serial Interface Module (Part Number 858303641). With the Serial Interface Module, the
light bar can be activated by Federal Signal light bar controllers or individual low current
switches.
The backbone is a powder coated aluminum shroud. The light bar has 15-foot power and
ground cables and a 25-foot control cable. Mounting hardware is a configured option.
Refer to mounting instructions supplied with mounting hardware. The light bar has an
operating temperature range of –30°C to +65°C (–22°F to +149°F).
FSJoin
Spectralux SIFxJ ILS models with FSJoin allow flash patterns to synchronize with other
FSJoin compatible devices. You can program light bar patterns and features on an
individual light head basis with the Convergence Network Configuration Software.
Outputs or light heads set to the same flash rate automatically synchronize. You can
program a variety of system features with the Convergence Network Configuration
