Safety Message to Installers and Service Personnel of Warning Lights
Before Installation or Service
Qualications
• To properly install or service this equipment, you must have a good understanding of automotive
mechanical and electrical procedures and systems, along with prociency 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
• In order to be an effective 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 eld of vision, so the driver
can maintain safe vehicle operation.
• Federal Signal power supplies and light heads are designed to work together as a system. Combining
light heads and a power supply from different manufacturers may reduce the warning effectiveness of
the lighting system and may damage the components. You should verify or test your combination to
make sure 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 off. After disconnecting power to the unit,
wait ve minutes before handling any parts of the strobe system.

Chapter 1: Safety Messages

Integrity Lightbar
• 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
effect 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. Be sure to 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 and result in ying glass.
Always wear gloves and eye protection when handling these components.
• Do not mount a radio antenna within 18 inches 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 elds.
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 this or any other electrical device while it is connected to its power source.
Exposure to liquid while the product is connected to the power source may result in an electrical shock
and personal injury and may short circuit and damage the product.
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.
• To avoid a battery explosion, always disconnect the negative battery cable rst and reconnect it last.
Avoid causing a spark when connecting near or to the battery. The gases produced by a battery can cause
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 veried 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 res or ying 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.
• Before mounting any components, check the manual to be sure 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.

Chapter 1: Safety Messages
8Integrity Lightbar
• 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 the mounting screws do not cause
electrical or mechanical damage to the vehicle.
• Because vehicle roof construction and driving conditions vary, do not drive a vehicle with a
magnetically mounted warning light installed. The light could y off 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 lightbar mounting feet as close to outer edge of the
roof as possible.
• Roof damage can occur if the hook adjustment bolts are over-tightened. On Arjent® lightbars tighten
the adjustment bolts 10 ft-lb to 11 ft-lb. On all other lightbar models torque 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.
• If a seat is temporarily removed, verify with the vehicle manufacturer if the seat needs to be
recalibrated for proper airbag deployment.
• Test all vehicle functions, including horn operation, vehicle safety functions and vehicle light
systems, to ensure proper operation. Ensure that the installation has not affected the vehicle operation
or changed any vehicle safety function or circuit.
• Scratched or dull reectors, mirrors or lenses will reduce the effectiveness 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 de-activate the light system control while driving in a hazardous
situation.
• You should frequently inspect the light system to ensure that it is operating properly and that it is
securely attached to the vehicle.
• After installation and testing are complete, provide a copy of these instructions to instructional staff
and all operating personnel.
• Do not use a pressure washer to clean the lightbar. Failure to heed this notice will damage the lightbar.

Safety Messages to Operators of Federal Signal Sound/Light Systems
People’s lives depend on your safe operation of Federal Signal products. It is important to read and follow all
instructions shipped with the products. In addition, listed below are some other important safety instructions
and precautions you should follow:
• Do not attempt to activate or de-activate the light system control while driving in a hazardous situation.
• Although your warning system is operating properly, it may not be completely effective. People may not
see or heed your warning signal. You must recognize this fact and continue driving cautiously.
• Also, situations may occur which 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.
• All effective 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.
• The effectiveness 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 effectiveness 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.
• To be an effective 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.
• You should only operate your vehicle and the light/sound system in accordance with 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 off, disconnect the power connector from the control unit and contact the nearest service center.
• At the start of your shift, you should ensure that the entire warning light system and the siren system is
securely attached and operating properly.
• Suction cup mounting is for temporary applications only. Window-mounted warning lights 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 be sure the suction cups have
a rm grip on the mounting surface. An improperly secured light could fall off of the vehicle causing
injury and damage.
• The holding power of magnetic mounting systems is dependent upon surface nish, surface atness, and
thickness of the steel mounting surface. Therefore, to promote proper magnetic mounting:

Chapter 1: Safety Messages
10 Integrity Lightbar
✔ The mounting surface and the magnets must be kept clean, dry, and free of foreign particles that
prevent good surface contact.
✔ Ensure that mounting surface is at.
✔ A magnet mounting system should not be used on vehicles with vinyl tops.
✔ To prevent sliding of light assembly on mounting surface, quick acceleration and hard stops
should be avoided.
Failure to follow all safety precautions and instructions may result in property damage, serious injury,
or death.

Integrity Lightbar
CHAPTER 2
An Overview of the IntegrityTM Lightbar
The INTEGRITYTM lightbar is a single-level LED lightbar with ROCTM (Reliable On-Board Circuitry)
and Solaris®LED technologies. ROC eliminates approximately 85 percent of potential failure points by
incorporating a printed circuit board (PCB) in one assembly to substantially reduce the number of electrical
connections. Solaris S2 LED modules use offset, complex reector surfaces for accurate beam-shaping and
the highest optical efciency. The reectors’ overlapping, 360-degree lighting eliminates weak spots and
provides off-axis warning around the lightbar.
LED Lights, Colors, and Flash Patterns
The microprocessor inside the lightbar supplies three priority operational modes and a library of 27 ash
patterns. To increase the safety of ofcers, pedestrians, and motorists, the lightbar has standard front and rear
cutoff, dimming, and intersection warning. Bright white LED takedown and alley lights that are horizontally
adjustable are also available with the HotFoot™ congured option.
Multi-color heads are available with up to three different colored LEDs, eliminating the loss of primary
warning colors in takedown, alley, and directional warning positions. Individual INTEGRITY lightheads can
ash between red, blue, amber, or white.
Electrical System
The INTEGRITY lightbar is protected against reversed polarity damage. The INTEGRITY Lightbar can be
installed in any vehicle with a 12-volt negative-ground electrical system.
Controller Options
Flash patterns are controlled through the lightbar CAT5 communication cable. The cable connects to Federal
Signal Convergence network controllers, the Serial Interface Module (Part Number 8583446), or the Federal
Signal Six-Button Serial Controller.
With the Serial Interface Module, the INTEGRITY Lightbar can be activated by Federal Signal lightbar
controllers, SignalMaster directional-light controllers, or by individual low-current switch boxes.
Ambient Light Sensor/AutoDim Option
The INTEGRITY lightbar can be ordered with an optional ambient light sensor. The sensors that detect the
ambient light and automatically dim ashing lights during nighttime are located on the ROC boards at each end
of the lightbar. If used with a controller that has a dedicated dim button, the user has the option to temporarily
override the dimming. AutoDim is disabled in MODE 3 and is enabled when MODE 3 is removed.

Chapter 2: An Overview of the Integrity Lightbar
12 Integrity Lightbar
Other advanced features of the INTEGRITY lightbar include:
• A high degree of reliability through the use of advanced microprocessors and other integrated circuits.
• One-piece seamless construction that eliminates leaking bulkhead gaskets.
• High output, long-life LEDs with no bulbs to change.

Reprogramming the Lightbar
HEAVY OBJECT—Use lifting aids and proper lifting techniques when removing or
replacing this product. Failure to follow this warning may cause personal injury.
Carefully unpack the lightbar assembly and any other products included in the shipment. Inspect them for
damage that may have occurred during shipping. If a product has been damaged, do not install or operate it.
Immediately le a claim with the carrier describing the damage.
Carefully check all envelopes, shipping labels, and tags before removing or destroying them. If you are
missing any parts, contact Customer Support at 1-800-264-3578, 7 am to 5 pm, Monday through Friday (CT).
Reprogramming the Lightbar
Although the INTEGRITY lightbar is congured and programmed at the factory, you may want change
default settings and ash patterns before you install the lightbar. Before you begin, decide if you want to
change these default settings:
• SignalMaster Operation: Internal (Factory Default) or External
Internal operation uses the on-board SignalMaster controller in the lightbar to generate directional
warning patterns. With Internal operation, an external SignalMaster controller is not needed. A standard
low-current switch box can activate the internal SignalMaster controller.
• MODE 1, 2, 3, and INTERSECTION
MODES 1 through 3 are most often selected by a progressive slide switch, which enables the driver to
turn on the lightbar without looking down. You can select a pattern for each mode from the lightbar’s
library of 26 patterns.
The INTERSECTION ash pattern is typically a high activity pattern that attracts attention to the vehicle
as it approaches an intersection. You can select a pattern from the library and choose one of three ways to
turn on and off the pattern. The INTERSECTION ash pattern overrides the three priority modes.
NOTE: If the SignalMaster ash pattern is turned on, it overrides the current ash pattern.
• FRONT and REAR lights: CUTOFF (default) or ENABLE
Set these options after you change the default settings for MODE and INTERSECTION ash patterns.
CUTOFF turns OFF the front or rear LEDs when 12 Vdc is applied to the FRONT or REAR light
control wire. ENABLE turns ON the front or rear LEDs when 12 Vdc is applied.

pattern, move Switch 5 to ON (up position) on SW-2.
SW-2 DIP Switch Settings in the Serial Interface Module
For the location of SW-2, see Figure 3.2 on page 15. Table 3.1 on page 15 lists the DIP switch settings in
the Serial Interface Module for programming ash patterns.
Programming Priority MODES 1, 2, 3, and INTERSECTION
The three modes operate with MODE 3 having the highest priority: MODE 3 overrides MODE 2, and
MODE 2 overrides MODE 1. When the lightbar operates in one of these modes, the SignalMaster
modules keep sequence with the ash pattern.
You can change default MODE ash patterns by programming each mode with one of 26 patterns in the
lightbar’s library. A typical setup would be:
• MODE 1: REAR LEDs
• MODE 2: FRONT/REAR LEDs
• MODE 3: Siren (SmartSiren
®
or Federal Signal compatible), and FRONT/REAR LEDs and FLASH
TAKEDOWN/ALLEY LEDs on the mainbar
• MODES 1 and 2: FRONT/REAR CUTOFF
NOTE: If you are reprogramming the lightbar after you have connected a progressive slide switch, the
programming sequence must be MODE 3, MODE 2, MODE 1, INTERSECTION.

The INTERSECTION ash pattern overrides all three priority modes when activated. To select a new
pattern, you must apply 12 Vdc to the control wire for either MODE 1, 2, or 3 (Table 3.2 on page 16)
and the blue/black control wire for INTERSECTION.
NOTE: This procedure only programs the INTERSECTION pattern. It does not assign the pattern to a
MODE.
1. Apply 12 Vdc (+BAT) to a control wire for either MODE 1, 2, or 3, and the control wire for
INTERSECTION from the Serial Interface Module.
2. On the Serial Interface Module, press and release the SW-1 pushbutton until the pattern you want
appears on the lightbar.
3. Remove 12 Vdc from the MODE and INTERSECTION control wires.
Intersection Operational Settings
Select one of three options to turn on the INTERSECTION pattern:
• HIGH with +BAT power maintained (default): the lightbar displays the INTERSECTION pattern
until power is removed.

• TAP II (push-on/push-off): the INTERSECTION ash pattern is turned on and off by pressing a
momentary contact switch, such as a horn button. Momentary 12 Vdc turns on the pattern, a second
momentary 12 Vdc signal turns it off.
• 8-SECOND TIMEOUT activated by +BAT: momentary 12 Vdc turns on the INTERSECTION ash
pattern for eight seconds.
To change from HIGH to TAP II or 8-SECOND TIMEOUT.
1. Unplug the 24-pin harness from the Serial Interface Module.
2. On the Serial Interface Module, set Switch 7 and Switch 8 on SW-2 to select a method of operation
(Table 3.3). Each setting is independent of the other.
3. Plug the 24-pin harness into the Serial Interface Module.

Front/Rear Enable or Cutoff
The operational setting for FRONT/REAR ENABLE or CUTOFF must be programmed after MODE
and INTERSECTION. The default setting is for CUTOFF in which the FRONT or REAR LEDs turn
off when 12 Vdc (+BAT) is applied to their control wires (Table 3.2 on page 16). In contrast, FRONT/
REAR ENABLE turns on these LED modules when +BAT is applied to their control wires. Both
FRONT and REAR share the same operational setting and are not independent.
To program the lightbar for FRONT/REAR ENABLE or CUTOFF:
1. Unplug the 24-pin harness from the Serial Interface Module.
2. On the Serial Interface Module, move Switch 1 on SW-2 to:
a) the down (on) position for Front/Rear Enable.
b) the up (off) position for Front/Rear Cutoff.
3. Plug the 24-pin harness into the Serial Interface Module.
NOTE: When set to ENABLE, 12 Vdc must be applied to a MODE control wire and the FRONT and/or
REAR ENABLE control wire for the lightbar to operate.
In a typical installation, if you want only the REAR LED modules to ash in MODE 1, set the operation
for ENABLE. Connect the green/white and blue/white control wires to the MODE 2 connection and the
orange/black and blue control wires to the MODE 1 connection.
