• 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 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 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.

Installation, Maintenance, and Service Manual
Federal Signal www.fedsig.com
• 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 and
result in flying 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 fields. Mounting the antenna too close to
the lighting system may also cause the radio noise emitted from the lighting system to

An Overview of the Integrity® Light Bar
10 Integrity Light Bar
Federal Signal www.fedsig.com
An Overview of the Integrity®Light Bar
The Integrity light bar is a single-level LED light bar 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 oset, complex reflector surfaces for accurate beam-shaping and the highest
optical eciency. The reflectors’ overlapping, 360-degree lighting eliminates weak
spots and provides o-axis warning around the light bar.
LED Lights, Colors, and Flash Patterns
The microprocessor inside the light bar supplies three priority operational modes and a
library of 27 flash patterns. To increase the safety of ocers, pedestrians, and motorists,
the light bar has standard front and rear cuto, dimming, and intersection warning. Bright
white LED takedown and alley lights that are horizontally adjustable are also available
with the HotFoot™configured option.
Multi-color heads are available with up to three dierent colored LEDs, eliminating the
loss of primary warning colors in takedown, alley, and directional warning positions.
Individual Integrity light heads can flash between red, blue, amber, or white.
Electrical System
The Integrity light bar is protected against reversed polarity damage. The Integrity
Light Bar can be installed in any vehicle with a 12-volt negative-ground electrical
system.
Controller Options
Flash patterns are controlled through the light bar 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 Light Bar can be activated by Federal
Signal light bar controllers, SignalMaster directional-light controllers, or by individual
low-current switch boxes.
Ambient Light Sensor/AutoDim Option
The Integrity light bar can be ordered with an optional ambient light sensor. The sensors
that detect the ambient light and automatically dim flashing lights during nighttime are
located on the ROC boards at each end of the light bar. 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.
Other advanced features of the Integrity light bar 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 Light Bar
HEAVY OBJECT: Use lifting aids and proper lifting techniques when removing or
replacing this product. Failure to heed this warning may cause personal injury.
Carefully unpack the light bar 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 file 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 to
5 , Monday through Friday (CT).
Reprogramming the Light Bar
Although the Integrity light bar is configured and programmed at the factory, you may
want to change the default settings and flash patterns before installation. 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 light bar
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 light bar without looking down. You can select a
pattern for each mode from the light bar’s library of 26 patterns.
• The INTERSECTION flash 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 o the pattern. The INTERSECTION flash
pattern overrides the three priority modes.
NOTE: If the SignalMaster flash pattern is turned on, it overrides the current flash pattern.
FRONT and REAR lights: CUTOFF (default) or ENABLE
• Set these options after you change the default settings for MODE and INTERSECTION
flash 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.
Making the Electrical Connections for Reprogramming
To supply power to the light bar, use a fully-charged 12-volt automotive battery and follow
these steps:
1. Place the light bar on a sturdy, flat surface.
2. Plug the CAT5 communication cable (1) from the light bar into the Serial Interface
Module (J1). See Figure 1.

Entering Program Mode
To switch the module from Operation Mode to Program Mode:
1. Unplug the 24-pin harness from the Serial Interface Module.
2. On the Serial Interface Module, move Switch 6 on SW-2 to the down (ON) position.
3. Plug the 24-pin harness into the Serial Interface Module.
NOTE: When you press and release the SW-1 button on the Serial Interface Module to
select a pattern, the light bar briefly turns o and then displays the next pattern. To cycle
backwards to a previous 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 2 on page 15. Table 4 on page 14 lists the DIP
switch settings in the Serial Interface Module for programming flash 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 light bar operates in one of these
modes, the SignalMaster modules keep sequence with the flash pattern.
You can change default MODE flash patterns by programming each mode with one of 26
patterns in the light bar’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 main bar
• MODES 1 and 2: FRONT/REAR CUTOFF
NOTE: If you are reprogramming the light bar after you have connected a progressive slide
switch, the programming sequence must be MODE 3, MODE 2, MODE 1, INTERSECTION.
Mode 3
1. Apply 12 Vdc (+BAT) to the MODE 3 control wire (black/red) from the Serial Interface
Module to display the assigned pattern.
2. On the Serial Interface Module, press and release the SW-1 button until the pattern
you want appears on the light bar.
3. Remove 12 Vdc from the MODE 3 control wire.
Mode 2
1. Apply 12 Vdc (+BAT) to the MODE 2 control wire (blue/white) from the Serial Interface
Module to display the assigned pattern.

1. Apply 12 Vdc (+BAT) to the MODE 1 control wire (blue) from the Serial Interface Module
to display the assigned pattern.
2. On the Serial Interface Module, press and release the SW-1 button until the pattern
you want appears on the light bar.
3. Remove 12 Vdc from the MODE 1 control wire.
Intersection
The INTERSECTION flash 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 5 on page 15) 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 button until the pattern
you want displays on the light bar.
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 light bar displays the INTERSECTION
pattern until power is removed.
• TAP II (push-on/push-o): The INTERSECTION flash pattern is turned on and o 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 o.
• 8-SECOND TIMEOUT activated by +BAT: Momentary 12Vdc turns on the
INTERSECTION flash 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 6). Each setting is independent of the other.
3. Plug the 24-pin harness into the Serial Interface Module.

Front/Rear Enable or Cuto
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 o when 12 Vdc (+BAT) is applied to their control wires (Table 5 on
page 15). 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 light bar 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:
• the down (on) position for Front/Rear Enable.
• the up (o) position for Front/Rear Cuto.
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 light bar to operate.
In a typical installation, if you want only the REAR LED modules to flash 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.
Exiting Program Mode
When you are finished, switch the Serial Interface Module from Operation Mode to
Program Mode:
1. Unplug the 24-pin harness from the Serial Interface Module.
2. On the Serial Interface Module, move SW-2 Switch 6 to the up (OFF) position.
3. Plug the 24-pin harness into the Serial Interface Module.

Wiring the Integrity Light Bar in the Vehicle
Before proceeding, ensure that the light bar has been installed on the vehicle roof in
accordance with the instructions included with the mounting kit. Depending on the type
of vehicle and mounting system feature, there are two options available for installing the
light bar to the roof of the vehicle: hook-on mounting or permanent mounting.
INSTALLATION PRECAUTION: 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.
Planning the Electrical Installation
The light bar is completely wired at the factory and does not require any additional
internal wiring. All the conductors necessary for control of any and all basic and optional
functions are contained in the CAT5 cable. The basic light functions of the Integrity must
be controlled by a installer-supplied control head.
To prevent damage to the light bar and vehicle and to ensure that all equipment operates
properly, carefully plan where to mount and wire the light bar and controlling equipment:
1. Verify that the light bar and mounting hardware fit the vehicle.
2. Determine where to mount the light bar on the vehicle.
3. Determine where to mount the controlling equipment:
• Trunk or remote location
• Console
AIRBAG DEPLOYMENT: Do not install equipment or route wiring in the
deployment path of an airbag. Failure to observe this warning will reduce the
eectiveness of the airbag or potentially dislodge the equipment, causing serious
injury or death.
4. Decide where to route wiring around airbag areas.
5. Decide where to route the light bar power and ground wires.
6. To make wiring easier, remove the seats, spare tire, and pull down the headliner
where needed.
7. Separate all electronic equipment wiring from two-way radio equipment wiring.
8. To avoid interference, keep two-way radio antennas a minimum of 18 in (45.7 cm) away
from warning equipment.
9. Whenever possible, run full wire lengths. DO NOT splice the wires.

10. Do not coil excess wire. Leave a drain loop for servicing.
11. After drilling holes for wires, de-burr them, smooth sharp edges, and insert grommets
to protect the wires from chafing.
12. When you frame ground the equipment, use the manufacturer-supplied ground
locations in the vehicle.
IMPORTANT: After the installation, frequently inspect the light bar and mounting feet to
ensure that all fasteners and brackets are tight.
Connecting Power to the Light Bar
NOTE: Plan the location of the wire routing hole in the vehicle roof so that the power
and communication cables do not have tight bends and have some slack to allow
disconnection on removal.
BATTERY EXPLOSION: 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.
SEAT REMOVAL PRECAUTION: If a vehicle seat is temporarily removed, verify
with the vehicle manufacturer if the seat needs to be recalibrated for proper airbag
deployment. Failure to follow this warning cause serious injury or death.
REVERSE POLARITY / MISWIRING: Reverse polarity or incorrect voltage may
damage the light. To avoid damage to the light, ensure that the battery voltage
is the same as the voltage rating of the light and that the correct polarity is
observed. If you are connecting to a cigarette lighter plug or 12 V outlet, connect
the positive wire to the center terminal and connect the negative wire to the outer
terminal.
To make the power connections:
1. Ensure that the lines are adequately fused as shown in Figure 3 on page 21.
2. From the light bar, route the CAT5 control cable into the vehicle cab or trunk near the
eventual location of the Serial Interface Module. An input cable is also provided with
the Interface Module.
3. Route and connect the black lead from the light bar to the vehicle battery’s ground
(–GND) terminal.
4. Route and connect the red lead from the light bar through a 40 A MAXI®fuse at the
source, which is the positive battery terminal (+BAT).
