Safety Message to Installers and Service Personnel of
Warning Light Equipment
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
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 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 field 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
• 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.

Legend LGD and Legend LPX Lightbars
Warning Light Equipment
•
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 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.
•
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.
• 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 fly 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 Legend lightbars torque each
hook adjustment bolt 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.

Safety Messages
• 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.
Safety Message to Operators of Warning Light Equipment
Safety Messages
After Installation or Service
• After installation, test the light system to ensure that it is operating properly.
• 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 reflectors, 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.

Failure to follow all safety precautions and instructions may result in property damage, serious injury,
or death.
RETAIN AND REFER TO THIS MESSAGE
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.
• 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.
• 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.
• It is important that you fully understand how to safely operate this warning system before use.

Legend LGD and Legend LPX Lightbars
Safety Message to Operators of Warning Light Equipment
• 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 firm 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 finish, surface flatness, 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 flat.
✔ 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.

Overview of the Legend Lightbar
The Legend and Legend LPX lightbars are single-level LED lightbars with ROC™ (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 reflector surfaces for accurate beam-shaping and the
highest optical efficiency. The reflectors' overlapping, 360-degree lighting eliminates weak spots and provides
off-axis warning around the lightbar.
The lightbar's internal microprocessor supplies three priority operational modes and a library of 26 flash patterns.
To increase the safety of officers, pedestrians, and motorists, the lightbar has standard front and rear cutoff,
dimming, and intersection warning. Bright white LED takedown lights, LED alley lights, and LED worklights are
available in the lightbar.
Flash patterns are controlled through the lightbar’s CAT5 serial communication cable. The cable connects to the
Federal Signal Serial Interface Module (Model Number 8583446), the Federal Signal Six-Button Serial Controller
(Model Number 8623133), the Federal Signal Three-Button Serial Controller (Model Number 8623141), or the
Six-Button Wireless Controller (8623137). With the Serial Interface Module, the Legend can be activated by
Federal Signal lightbar controllers, SignalMaster directional light controllers, or by individual low-current switch
boxes. (SignalMaster directional warning lights are not available with the Model LGD12, LGD24, LGD32, LPX24.
LPX32, or any of LPXD models. The programmable Six-Button Serial Controller and the Six-Button Wireless
Controller have six illuminated pushbuttons and a three-position slide switch with LED indicators for operating the

Model LPXD Light Activation
Model LPXD Light Activation
The operational mode of the Model LPXD Discrete-Wire Legend is dependent upon the variation of options
incorporated into the final model. Installation, wiring, and operation instructions are in the instructions supplies
with the Model LPXD. The functions defined in Table 2.3 are activated via +12 Vdc applied to any of the wires
shown in Table 2.3 except for the green pattern-selection wire, which is ground activated. There are eight flashing
patterns available, which are described in Table 2.4.
Follow the standard installation from the Legend (LGD) instructions. Federal Signal recommends fusing each
wired connection in Table 2.3 with the fuse shown in the table. See Schematic A.7 on page 56.

Preparing the Legend 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 bench testing, this chapter has instructions for
changing default settings and flash patterns.
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 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 am to 5 pm, Monday through Friday (CT).
Changing the Default Settings
Although the lightbar is configured and programmed at the factory, you may want change 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
You can change the setting from Internal to External. INTERNAL operation uses the lightbar’s on-board
SignalMaster controller 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.
EXTERNAL operation uses the Serial Interface Module to drive each SignalMaster directional warning head
independently through an external Federal Signal SignalMaster controller or SS2000SM series siren
• 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 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 off 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
You 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.

Changing the Default Settings
Making the Initial Electrical Connections
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 Legend 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. (The Discrete-Wired 24" Legend does not connect to the Serial Interface
Module and has no CAT5 cable.) For wiring schematics, see the Appendix starting on page 47.
To make the electrical connections for reprogramming the lightbar:
1. To supply power to the lightbar, use a fully-charged 12-volt automotive battery with terminal lugs.
2. Place the lightbar on a sturdy, flat surface.
3. Plug the CAT5 communication cable (1) from the lightbar into the Serial Interface Module (J1) (Figure 3.1).
4. Plug the 24-pin harness (2) into the Serial Interface Module.
5. Attach the lightbar’s black ground-power line (3) to the negative battery (–GND) lug.
6. Attach the lightbar’s red power line (4) through a 40 A Maxi™ fuse to the positive battery (+BAT) lug.
7. Attach the white wire (5) from the 24-pin harness through a 1 A fuse to the positive battery (+BAT) lug.
8. Attach the black wire and the black/white wire (6) from the 24-pin harness to the negative battery (–GND) lug.

Switch 5 to ON (up position) on SW-2.
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 flash pattern. You can change default MODE flash 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 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.

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 flash 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.
•

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. 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 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 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 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 SW-2 Switch 6 to the up (OFF) position.
3. Plug the 24-pin harness into the Serial Interface Module.

Wiring the Legend in the Vehicle
Before wiring the lightbar in the vehicle, mount the lightbar according to the instructions included with the
mounting kit.
The lightbar is completely wired at the factory and does not need any additional internal wiring. For typical
installations with common control systems, see the wiring schematics in the Appendix starting on page 47. The
basic light functions of the lightbar must be controlled by a user-supplied control panel.
Wiring the Lightbar in the Vehicle
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.
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.
BATTERY EXPLOSION
To avoid a battery explosion, always disconnect the negative cable first 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.
1. Ensure that the lines are adequately fused as shown in the wiring schematics in the Appendix starting on
page 47. From the lightbar, route the CAT5 control cable into the vehicle’s cab or trunk near the eventual
location of the Serial Interface Module. An input cable is also provided with the Interface Module.
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, connect the positive wire to the center
terminal and connect the negative wire to the outer terminal.
2. Route and connect the lightbar’s black lead to the vehicle battery’s ground (–GND) terminal.
3. Route and connect the lightbar’s red lead through a 40 A Maxi™ fuse and fuse holder (or equivalent) at the
source, which is the positive battery terminal (+BAT).
25
Mounting the Serial Interface Module
Mounting the Serial Interface Module
The Serial Interface Module communicates between a user-supplied lightbar/siren controller, a SignalMaster
controller, or a switch box and the Legend. To minimize the number of discrete wires to the lightbar, control lead
functions are wired to the Interface Module through a 3-foot long, 24-conductor cable harness (Table 3.1 on
page 19). The information is converted to a digital format and communicated to the lightbar through the CAT5
serial communication cable. (The Discrete-Wired 24" Legend does not connect to the Serial Interface Module.)
LOCATION OF LIGHT SYSTEM CONTROLS
Light system controls must be located so that VEHICLE and CONTROLS can be operated safely under
all driving conditions.
NOTE: If you are using the External SignalMaster option, you must configure the Serial Interface Module for
External operation before installing it as described in “Selecting External SignalMaster Control” on page 20.
Wiring the Legend
in the Vehicle
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.
UNIT REQUIRES VENTILATION
The Serial Interface Module needs to radiate heat. Do not install it in an area where it cannot dissipate
heat into the air. Do not mount it near a heater duct.
IMPORTANT: The Serial Interface Module must be installed within 36 in (91 cm) of the lightbar controller.
1. Use the Serial Interface Module as a template and scribe four drill-position marks at the selected mounting
location. Mounting centers are 2 in x 5.95 in (5.08 cm x 15.11 cm).
DRILLING PRECAUTIONS
DO NOT drill holes in ANY part of the Serial Interface Module. Damage to the unit, serious injury or
death may result.
DRILLING PRECAUTIONS
Before drilling holes, check the area into which you plan to drill to ensure you do not damage
vehicle components while drilling. All drilled holes should be de-burred and all sharp edges should
be smoothed. All wires going through drilled holes should be protected by a grommet or convolute/
split-loom tubing.
2. Drill four mounting holes at the drill-position marks, sized for the recommended user-supplied #8 mounting
hardware.
3. Secure the Serial Interface Module to the mounting surface with user-supplied #8 mounting hardware.
4. Install the lightbar’s CAT5 serial cable to the J3 output jack of the Serial Interface Module.
5. Install the three-foot-long, 24-conductor cable to the J1 input connector of the Serial Interface Module.

Wiring the Serial Interface Module
SHOCK HAZARD
Strobe and HID light systems generate high voltages. Disconnect power from the system and wait
at least 5 minutes before opening the unit. Do not apply power to the unit while the unit is open.
Failure to follow this warning could result in serious injury or death.
NOTE: Powering multiple devices with a common control wire may cause one or more devices to briefly
remain functional after signal power is removed. For example, due to the high input filter capacitance, a
strobe supply can briefly supply the current required to signal a lightbar function to remain ON. If necessary,
use a relay to isolate devices with large filter capacitors (Figure 4.1). All components/wires are user-supplied.

Wiring the Serial Interface Module
For wiring the controller’s functions to the Serial Interface Module’s 24-pin cable harness, see Table 4.1 on
page 30 and the figures on pages 30 though 32. If additional wire is necessary for the harness (except ground),
22 AWG wire is adequate. The ground wires must be extended with 16 AWG or better wire.
This section is an overview of default settings that are activated when connecting LED and MODE control wires to
12 Vdc (+BAT). All programming and changes to default settings should be done after bench testing the lightbar
and before installation. Programming is covered in “Programming Priority MODES 1, 2, 3, and INTERSECTION”
on page 21. For a description of the control wires from the Serial Interface Module, see Table 3.1 on page 19.
MODES 1, 2 , and 3
To activate a mode, apply 12 Vdc (+BAT) to a mode control wire. MODE 3 overrides MODE 2, and MODE 2
overrides MODE 1. You can program one of the 26 flash patterns in the lightbar’s library to each mode input.
STEADY BURN (LGD Models Only)
When the lightbar is equipped with one or more STEADY BURN LED modules, applying 12 Vdc (+BAT) to the
STEADY BURN control wire (red/white) turns on the LEDs when any MODE input is selected.
Wiring the Legend
in the Vehicle
The STEADY BURN LEDs are factory configured per the customer order for one of these options:
•
No STEADY BURN (the LEDs flash with the pattern)
•
Driver’s side STEADY BURN
•
Driver’s and passenger’s side STEADY BURN
FRONT CUTOFF*
When 12 Vdc (+BAT) is applied to the FRONT CUTOFF control wire, the selected MODE operation is deactivated
to the front of the lightbar. Only the rear LEDs function. Additionally, with FLASH TAKEDOWN/ALLEY active,
only the ALLEY lights turn on.
REAR CUTOFF*
When 12 Vdc (+BAT) is applied to the REAR CUTOFF control wire, the selected MODE operation is deactivated
to the rear of the lightbar. Only the FRONT LEDs flash.
* NOTE: The operational setting for FRONT and REAR CUTOFF are not independent. The default setting is for
12 Vdc (+BAT) to be applied for the lightbar’s front and rear lightheads to turn them off (CUTOFF). To change
the default setting to turn on these LEDs when 12 Vdc is applied (ENABLE), see “FRONT/REAR ENABLE or
CUTOFF” on page 23.
INTERSECTION
When 12 Vdc (+BAT) is applied to the INTERSECTION control wire and a MODE control wire, it turns on the
INTERSECTION pattern. When 12 Vdc is removed, the lightbar returns to its previous state.
FLASH TAKEDOWN/ALLEY
When 12 Vdc (+BAT) is applied to the FLASH TAKEDOWN/ALLEY control wire and a MODE control wire, the
TAKEDOWN and ALLEY lights flash.
LEFT and RIGHT ALLEY Lights
When 12 Vdc (+BAT) is applied to the LEFT or RIGHT ALLEY control wire, the appropriate ALLEY LEDs turn on.
The LEFT and RIGHT ALLEY lights override the FLASH TAKEDOWN/ALLEY lights.
TAKEDOWN Lights
When 12 Vdc (+BAT) is applied to the TAKEDOWN control wire, the TAKEDOWN LEDs turn on. TAKEDOWN
overrides FLASH TAKEDOWN/ALLEY and FRONT CUTOFF.
28
Legend LGD and Legend LPX Lightbars
Wiring the Serial Interface Module
WORKLIGHTS
When 12 Vdc (+BAT) is applied to the WORKLIGHT control wire, the WORKLIGHT LEDs turn on.
LOW POWER
USE LOW POWER FUNCTION PROPERLY
Enabling the LOW POWER function in the lightbar will cause the light output to fall below current
light output standards and guidelines for emergency warning lights. Use extreme caution when using
this function. Ensure that the ambient light conditions are low enough that you are seen and that the
reduction of glare from the lightbar is safer than full light output in the situation. Failure to heed this
warning may result in serious injury or death to you or others in your vicinity.
NOTE: Low power mode is disabled when the lightbar is in MODE 3 or displaying the INTERSECTION flash
pattern.
When 12 Vdc (+BAT) is applied to the LOW POWER control wire, the LEDs are dimmed to approximately
50 percent of their full brightness. LOW POWER is only functional in MODE 1 or MODE 2. LOW POWER
is disabled when switching to another flash pattern, including INTERSECTION. To use LOW POWER again,
disconnect 12 Vdc from the LOW POWER control wire and reapply 12 Vdc to the LOW POWER control wire
after a change in flash pattern occurs.
Connect the white wire from the supplied J1 cable harness on the Interface Module to a 1 A fuse. Connect the
fuse end as close as possible to switched ignition power. Power should also be present in the cranking position.
Connect the black and black/white wire from the 24-pin cable harness on J1 from the Serial Interface Module to
battery ground (–GND). Use 16 AWG wire to extend the cable length.
SignalMaster Connections
If SignalMaster operation is not activated by a control head or external controller, the SignalMaster LED heads
flash with the selected priority mode (MODE 1, 2, or 3) of operation.
Internal SignalMaster
Internal operation (factory default setting) uses the lightbar’s built-in SignalMaster controller to generate
directional warning patterns. With internal operation, an external SignalMaster controller is not needed. A
standard low-current switch box can activate the lightbar’s internal SignalMaster controller.
For the jumper setting in the Serial Interface Module, see “Selecting Internal SignalMaster Control (Factory
Default" on page 21. To activate the lightbar’s internal SignalMaster controller, apply 12 Vdc (+BAT) to the
SignalMaster control wires.
External SignalMaster
External operation uses the Serial Interface Module to drive each SignalMaster directional warning head independently through an external Federal Signal SignalMaster controller or SS2000SM series siren (Figures
4.3 and 4.4 on page 30). Either device provides an independent ground signal to turn on each head. To cross
reference external SignalMaster wiring to a Federal Signal controller or the SM2000SM series siren, see
Table 4.1 on page 30.

Crazed, cracked or faded domes or reflectors reduce the light output and the effectiveness of the lighting
system. Tops or reflectors showing this type of aging must be replaced.
Failure to follow this warning may result in bodily injury or death to you or others.
CRAZING/CLEANING SOLUTIONS
The use of cleaning solutions, such as strong detergents, solvents, and petroleum products, can cause
crazing (cracking) of the domes and reflectors.
Failure to follow this warning can damage the domes and reflectors and may result in bodily injury or
death to you or others.
1. Rinse the domes with lukewarm water to loosen dirt and debris.
3. Rinse and dry the plastic surfaces with a soft cloth to prevent water spotting.
To remove fine scratches and haze, use a specialty plastic cleaner/polish such as Plexus® and a soft cloth. You
can also use a high quality automotive paste cleaner/wax that is non-abrasive.
The most effective product you can use for cleaning, protecting, and polishing clear and colored plastics is
Plexus. Over time, exposure to heat, sunlight, and smog causes plastic to fade, discolor, scratch, or become
brittle. Plexus seals the pores of the plastic, making the domes easier to clean, improving scratch resistance,
and increasing product longevity.

2. Use a mild soap, lukewarm water, and a soft cloth to gently clean the plastic surfaces. To avoid damaging
the reflectors, do not use heavy pressure or caustic, abrasive, or petroleum-based cleaners.

Problem
The lightbar does not
light
Corrective Action
✔ Check that the lightbar's red power line (+BAT) and the black ground- power
line (–GND) are properly connected to a good, fully charged 12-volt battery.
✔ Ensure that the ground connection from the lightbar controller to the aluminum
extrusion is good.
✔ Check that the CAT5 cable is connected to the Serial Interface Module (J1) and
there are no damaged pins in the sockets.
✔ Try a new CAT5 cable.
✔ Check the connections on the Serial Interface Module:
1. the black wire and the black/white wire are connected to ground (–GND)
2. the white wire is connected to 12 Vdc
3. a MODE wire has 12 Vdc
✔ Check the position of Switch 1 on SW-2 in the Serial Interface Module. If Switch
1 is down (ON), ensure that the ENABLE control wires (green/white and orange/
black) have 12 Vdc applied.
✔ Check the positions of the DIP switches in the Serial Interface Module. See Table
3.2 on page 20.
✔ Check the fuses on the mainbar controller (Figure 5.3 on page 39).
An LED module does
not light
✔ Swap the LED board with good board to see if the board is bad.
✔ Check the connections of the cable that goes from the lightbar controller to the
LED ROC board.
✔ Ensure that STEADY BURN switches on the lightbar controller (SW3 PSR for the

An Overview of the Discrete-Wired 24" Legend Lightbar
The Discrete-Wired 24" Legend is a special model that is designed to flash only one flash pattern as long as
power is supplied to the lightbar. Because the lightbar does not connect to the Serial Interface Module, it has no
CAT5 cable; the 10 AWG red and black cables are the only connections. An installer supplied-switch is required
(Figure A.1).
