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. In addition, listed below are some other important
safety instructions and precautions you should follow:
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 service manuals when performing equipment
installations on a vehicle.
Light Hazards
• 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
safely operate the vehicle.
• Federal Signal power supplies and lightheads are designed to work together as a system. Combining
lightheads 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 ensure
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,

7
Vision SLR Lightbar
Chapter 1 • Safety Messages
wait ve 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
affect 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 (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
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 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.
• 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 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 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.

Chapter 1 • Safety Messages
• 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, 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.
• 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 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 the outer edge of the
roof as possible.
• Roof damage can occur if the hook adjustment bolts are over-tightened. On Arjent®and Vista®lightbars
tighten the hook-adjustment bolts 10 ft-lb to 11 ft-lb. On all other lightbars 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 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

Chapter 1 • Safety Messages
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 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.
• 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.
• 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.
• 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.
• It is important that you fully understand how to safely operate this warning system before use.
• You should only operate your vehicle and its 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. 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 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.
• 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:
✓Mounting surface and 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 these precautions may result in property damage, serious injury, or death.

10 Vision SLR Lightbar
CHAPTER 2
An Overview of the Vision SLR Lightbar
The Vision SLR is a rotating LED lightbar, employing xed LED boards and rotating Solaris S2 reectors.
V-shaped construction lets the Vision SLR warning system maximize light warning efciency at crucial
intersection angles. The individual domes are shaped to eliminate critical dome angles, which reect rather
than transmit light in other lightbars, signicantly improving light transmission (brightness). Vision SLR
continues and improves its predecessor’s revolutionary aerodynamic styling to provide superior vehicle fuel
efciency and top speed.
LED Lights and Colors
The LED pods are positioned to provide 360-degree coverage. The warning system’s LED pods are
available in multi-color. Exclusive to Federal Signal, Spectralux Technology provides for entirely new
color combinations. One pod can have more than one color, for example, rotating red, then switching to
blue, and then to white when the takedown function is activated. Single color pods are also available. All
pods are Smart Pods and are preprogrammed to provide a wide selection of warning light patterns. Pattern
selection can be performed during or after installation. Take-down and alley functions of the LED pods have
horizontal tracking capability for use as spotlights.
Fixed LED Alley lights in the end caps are available as a congured option. Horizontally adjustable LED
takedown lights in the mounting feet are available with the HotFoot™ option (congured).
An optional LED rear directional light, the 8-head SignalMaster™, provides additional warning capability
using a common control. The SignalMaster has pre-programmed light patterns which provide supplemental
warning for any hazardous situation.
LED Flash Rates and Positions
Quiet, smooth, precise, and efcient positioning stepper motors control the Solaris S2 reectors and have
a longer life than conventional DC motors. The motors provides a variety of ash rate options, oscillation
angles, and the ability to jog a lighthead to the desired xed position. In addition, each reector allows two
LEDs to shine upward for the aerial location of the vehicle.
Modular Connector System (Optional)
The Vision SLR lightbar is available hardwired or with an optional waterproof (IP67) external connector
system for power and communication. The external connector enables you to remove the lightbar from
the vehicle without opening the lightbar or the vehicle hood (see page 43). The lightbar is protected
against reversed polarity damage. The Vision SLR Lightbar may be installed in any vehicle with a 12-volt
NEGATIVE ground electrical system.

Chapter 2 • An Overview of the Vision SLR Lightbar
11
Vision SLR Lightbar
Controller Options
Flash patterns are controlled through the lightbar’s CAT5 communication cable. The cable connects to
the Serial Interface Module (Part Number 8583446), the Federal Signal Six-Button Serial Controller (Part
Number 8623133), the Three-Button Serial Controller (Part Number 8623141), or the SmartSiren Series
Platinum System or the System control head only.
With the Serial Interface Module, the Valor Lightbar can be activated by Federal Signal lightbar controllers,
SignalMaster directional-light controllers, or by individual low-current switch boxes.
Other advanced features of the Vision SLR Lightbar include:
◆A high degree of reliability through the use of advanced microprocessors and other integrated circuits.
◆Modular construction with easily replaceable pods and domes to greatly reduce spare parts inventory.
◆High output, long-life LEDs with no bulbs to change.

CHAPTER 3
Preparing the Vision SLR for Installation
Taking the preparatory steps in this chapter before mounting and wiring the lightbar to a vehicle will help
ensure that your installation is fast, easy, and error free. In addition to instructions for quick testing the
lightbar, this chapter has instructions for changing default settings and ash patterns with the Serial Interface
Module. The number of available ash patterns vary between the Serial Interface Module and the SmartSiren
Platinum System. If you are using the SmartSiren Platinum System, refer to the “Smart Siren Platinum
Installation, Maintenance, and Service Manual” (Doc. No. 2562502) and to the “Smart Siren Platinum
Control Pad Conguration Software Manual” (Doc. No. 2562418) for programming instructions.
Unpacking the Lightbar
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 a.m.to 5 p.m., Monday through Friday (CT).
Connecting the Vision SLR for Programming
HEAVY OBJECT—Use lifting aids and proper lifting techniques when removing or
replacing this product. Failure to follow this warning may cause personal injury.
REVERSE POLARITY / MISWIRING—Reverse polarity or incorrect voltage may
damage the lightbar. To avoid damage to the lightbar, ensure that the battery
voltage is the same as the voltage rating of the lightbar and that the lightbar’s red
and black power lines are connected to the battery lugs in the correct polarity.
The Vision SLR does not require any internal wiring. Two 10 AWG power conductors (red and black) and a
CAT5 cable exit the lightbar. The lightbar’s basic light functions are communicated through the CAT5 cable,
which connects to the Serial Interface Module, SmartSiren Platinum, or other Federal Signal controllers.
The electrical connections in this section enable you to perform a quick test of the lightbar with the Serial
Interface Module. The Serial Interface Module communicates between an installer-supplied lightbar/siren
controller, a SignalMaster controller, or a switch box and the lightbar. To minimize the number of discrete
wires to the lightbar, control head functions are wired to the Module through a 3-foot-long, 24-conductor
cable harness (Table 3.2 on page 15). The information is converted to a digital format and communicated
through the CAT5 serial communication cable.

Selecting a Flash Pattern for Modes 3, 2, 1, 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 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), Front/Rear LEDs, and Flash Takedown/
Alley LEDs on the main bar
• Modes 1 and 2: Front/Rear Cutoff
NOTE: If the lightbar needs to be programmed after you connect a progressive slide switch, the
programming sequence must be Mode 3, Mode 2, Mode 1, Intersection.
When you press and release the SW-1 pushbutton on the Serial Interface Module to select a pattern, the
lightbar briey turns off and then displays the next pattern. To cycle backwards to a previous pattern,
move Switch 5 to ON (up position) on SW2.
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 pushbutton until the pattern you want
appears on the lightbar.

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.
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 2 control wire.
Mode 1
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 pushbutton until the pattern you want
appears on the lightbar.
3. Remove 12 Vdc from the Mode 1 control wire.
Intersection
This procedure only programs the Intersection pattern. It does not assign the pattern to a Mode. 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 15) and the blue/
black control wire for Intersection. SW2 Switch 3 on the Serial Interface Module must be in the up
position for this function.
NOTE: With the exibility of the SmartSiren Platinum System, both the Intersection and the Scene Light,
Left option are available in Vision SLR and Valor lightbars without the need to choose one or the other.
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 SW2 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.
Table 3.3 Switch settings for Intersection operation
Operational Settings
SW2
SW7 SW8
High (+BAT maintained) OFF (up) OFF (up)
Tap II (+BAT, push on/push off ) ON (down) OFF (up)
8-Second Timeout (activated by +BAT) OFF (up) ON (down)
Front/Rear Cutoff or Enable
The operational setting for Front/Rear Cutoff or Enable 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. In contrast, Enable turns on these LED modules when +BAT is
applied to their control wires. Both the front and rear LEDs share the same operational setting and are
not independent.
To program this feature:
1. Unplug the 24-pin harness from the Serial Interface Module.
2. On the Serial Interface Module, move Switch 1 on SW2 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.
Exiting Program Mode
When you are nished programming patterns, 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 SW2 Switch 6 to the up (OFF) position.
3. Plug the 24-pin harness into the Serial Interface Module.

Vision SLR Lightbar
CHAPTER 4
Wiring the Vision SLR in the Vehicle
Before proceeding, ensure that the lightbar 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 lightbar to the roof of the vehicle: hook-on mounting or
permanent mounting.
INSTALLATION PRECAUTIONS—The warning system and/or two-way radio system
may operate improperly if a two-way radio antenna installed on or within 18 inches
of the lightbar. Before permanently installing the lightbar or a two-way radio
antenna, test the warning system and two-way radio system. DO NOT install a two-
way radio antenna on the lightbar. Some installations may require the relocation of
the two-way radio antenna to a trunk or fender location. DO NOT drill holes in the
lightbar or install auxiliary devices on the lightbar or the warning system may fail.
Planning the Electrical Installation
The lightbar 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 Vision SLR must be controlled by a installer-supplied control head.
To prevent damage to the lightbar and vehicle and ensure that all equipment operates properly, carefully plan
where to mount and wire the lightbar and controlling equipment:
1. Verify that the lightbar and mounting hardware t the vehicle.
2. Determine where to mount the lightbar on the vehicle.
LOCATING OPERATOR CONTROLS—The controls for the light system must be
located so that the VEHICLE and CONTROLS can be operated safely under all
driving conditions.
UNIT REQUIRES SHELTER FROM WEATHER—The Serial Interface Module is NOT
waterproof. It must be mounted in a location that is sheltered from rain, snow,
standing water, etc.
AIRBAG DEPLOYMENT—Do not install equipment or route wiring in the deployment
path of an airbag. Failure to observe this warning will reduce the effectiveness of
the airbag or potentially dislodge the equipment, causing serious injury or death.

Chapter 4 • Wiring the Vision SLR in the Vehicle
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.
3. Determine where to mount the controlling equipment:
a) Trunk or remote location
b) Console
4. Decide where to route wiring around airbag areas.
5. Decide where to route the lightbar’s power and ground wires.
6. To make wiring easier, remove the seats, spare tire, and pull down the headliner where needed.
8. Separate all electronic equipment wiring from two-way radio equipment wiring.
7. To avoid interference, keep two-way radio antennas a minimum of 18 in (45.7 cm) away from warning
equipment.
8. Whenever possible, run full wire lengths. DO NOT splice the wires.
9. Do not coil excess wire. Leave a drain loop for servicing.
10. After drilling holes for wires, deburr them, smooth sharp edges, and insert grommets to protect the wires
from chang.
11. When you frame-ground the equipment, use the manufacturer-supplied ground locations in the vehicle.
IMPORTANT: After the installation, frequently inspect the lightbar and mounting feet to ensure that all
fasteners and brackets are tight.
Connecting Power to the Lightbar
NOTE: The VSLR can draw up to 350 mA in standby. To avoid battery drain, wire the lightbar to an ignition
activated switch capable of 30 A.
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 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 an electrical
explosion that could result in vehicle damage and serious injury.
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.
