Safety Message to Installers and Service Personnel of Warning Lights
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
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 also 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

Safety Messages
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.
• 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.
• Halogen light bulbs and strobe tubes are pressurized and if broken, can burst,
resulting in flying glass. Always wear gloves and eye protection when handling these
components.
• 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 ensure that there are no
shavings present in or near the unit.
• 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
gases produced by a battery can caused a battery explosion that could result in
vehicle damage and serious injury.
• 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.
• If a vehicle seat is temporarily removed, verify with the vehicle manufacturer if the
seat needs to be recalibrated for proper airbag deployment.

Safety Messages
• 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 other extreme environmental
exposure areas.
• The service life of light bulbs and strobes tubes will be shortened if the glass portion
is touched during installation. Use gloves when handling these components. If the
glass portion has been touched, clean the glass carefully with isopropyl alcohol.
• 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.
• Roof damage can occur if the hook adjustment bolts are over-tightened. Tighten the
adjustment bolts 6 ft-lb to 7 ft-lb. Install keeper plates.
• Locate the light system controls so the VEHICLE and CONTROLS can be operated
safely under all driving conditions.
After Installation or Service
• After installation, test the light system to ensure that it is operating properly.
• To ensure proper operation, test all vehicle functions, including horn operation,
vehicle safety functions, and vehicle light systems. Ensure that the installation has not
aected the vehicle operation or changed any vehicle safety function or circuit.
• Scratched or dull reflectors, mirrors, or lenses will reduce the eectiveness of
the lighting system. Avoid heavy pressure and use of caustic or petroleum based
products when cleaning the lighting system. Replace any optical components that
may have been scratched or crazed during system installation.
• Do not attempt to activate or deactivate the light system control while driving in a
hazardous situation.
• Frequently inspect the light system to ensure that it is operating properly and that it is
securely attached to the vehicle.

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.
• All eective sirens and horns produce loud sounds that may cause, in certain
situations, 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.
• Only operate your vehicle and its light/sound system per your department’s Standard
Operating Procedures.
• If a selected function does not perform properly or if any of the lamps remain illuminated
when the control is o, disconnect the power connector from the control unit and
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.

Introduction to the SIFZ Series SpectraLux
The SIFZ SpectraLux®ILS is a single-level LED light bar that mounts on the inside of the
front windshield. It uses ROC (Reliable On Board Circuitry) technology, and Solaris® S2
reflectors. Split, Passenger only, and Driver only are available. The light bar operates at
a nominal input of 13.6 Vdc (11 Vdc minimum). Both Discrete and Serial (Convergence
Network) 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 either a compatible Federal Signal Convergence Network
controller/siren or a Federal Signal Serial Interface Module (P/N 8583446). An internal
PCB assembly within the light bar decodes the control data and performs the requested
function. 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).
Selecting Conguration Options for the Serially-Controlled SIFZ
The serial controlled ILS has three configuration options that are selectable with
DIP switches on the light bar control board. The options are described in Table 1 on
page10.

Function
1 Sets what light heads turn on in Steady Burn. The default position for Switch
1 is OFF, which turns on the third outer heads on both sides of the Front ILS
(Figure 1 on page 10). To turn on the third outer head on the driver side only,
set Switch 1 to ON.
2 Not used
3 Switch 3 has two functions:
• Performing an LED scan to ensure that an LED board ashes the correct
colors after it is installed.
• Changing the Device ID to enable the SpectraLux ILS to operate
independently of the light bar (available with the Convergence
Conguration Software).
Performing an LED Scan
When an LED board is changed, an LED scan must be done to enable the
LED board to ash the correct colors.
To perform the scan:
1. Disconnect the red power (BAT+) wire to the SpectraLux®ILS and maintain
power to the control head.
2. Change the position of DIP Switch 3 and turn power ON to the SpectraLux
ILS. The SpectraLux ILS emits a short ash to indicate that the LED scan is
done.
3. To return DIP Switch 3 to its original function, repeat the scan.
Changing the Device ID
The default setting for the SpectraLux ILS is to respond to light bar commands.
For example, if the system includes a light bar and a SpectraLux ILS,
both devices perform the same functions. The Convergence Conguration
programming software enables you to program the control head to send a
set of commands dedicated only to the SpectraLux ILS, making its operation
independent of the light bar.
To reset the control head to the default setting, perform an LED scan as
described above.
4 Sets the ability to power the network cable for other devices. The default
is OFF. Switch 4 should be set only if the main power cables are turned on
through an ignition-activated relay. If powering other devices, such as the Six-
Button Serial Controller, set DIP Switch 4 to ON. For more information, see the
instructions included with the network-powered device.
Control Wires for the Serial Interface Module
The serially controlled SIFZ SpectraLux ILS connects to a Federal Signal Convergence
Network Siren/Controller or to the Serial Interface Module. Table 2 on page 11 shows
the functions of control wires from the Serial Interface Module. The first color of wire is the
wire predominant color and additional colors are stripes. For programming options, see
the instructions included with the Interface Module or the Federal Signal Convergence
Network Siren/Controller.
