Installation and Service Instructions
Federal Signal www.fedsig.
Overview of the QuadraFlare
The Federal Signal QuadraFlare Warning Light is a self-
contained, high intensity, LED light designed for mounting to
the exterior of a vehicle. All models are available in a variety of
colors and have an internal flasher. The internal flasher has 26
selectable flash patterns. All units are designed to work with
Federal Signal flashers. However, before they can operate with
a Federal Signal flasher, put internal flashers into pattern 20 or
21. Refer to the particular flasher instructions for proper wiring.
Additionally, all units have a Dim Mode (low power) that allows
the user to reduce the light brightness for nighttime use. The
QuadraFlare Warning Light is designed for operation on 12 Vdc
at 2.0A. The models can have one side switched o while the
opposite side continues to operate.
NOTE: All units should NOT be considered for steady burn
applications.
Unpacking the QuadraFlare
After unpacking the light, inspect it for damage that may have
occurred in transit. If the unit has been damaged, file a claim
immediately with the carrier, stating the extent of damage.
Carefully check all envelopes, shipping labels, and tags before
removing or destroying them. If installing a permanent mounted
beacon, ensure that the parts listed in Table 1 are included in the
package.

Installing the QuadraFlare
INSTALL IN RECOMMENDED AREAS: When installing equipment
inside airbag equipped vehicles, the installer MUST ensure that
the equipment is installed ONLY in areas recommended by the
vehicle manufacturer.
Failure to observe this warning reduces the eectiveness of the
airbag, damage the airbag, or potentially damage or dislodge the
equipment, causing serious injury or death to you or others.
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.
NOTE: For maximum coverage and eectiveness, mount the
light assembly in a horizontal orientation. See Figure1.
Before proceeding with installation, determine the approximate
location of the light assembly and plan all cable/wire routing.
To install the QuadraFlare:
1. Position the QuadraFlare Warning Light assembly on the
desired mounting surface. Ensure that the unit is level side
to side. Using the dimensions provided in Figure1, scribe
the four mounting hole locations and a wiring routing hole
location on the mounting surface.

any warranty claims for the light.
DRILLING PRECAUTIONS: When drilling holes, check the area
you are drilling into to ensure that you do not damage vehicle
components while drilling. All drilled holes should be de-burred,
and all sharp edges should be smoothed. All wire routings going
through drilled holes should be protected by a grommet or
convolute/split loom tubing.
2. Drill four 1/4-inch mounting holes and a one-inch wire routing
hole at the previously scribed locations.
3. Install the four supplied rubber rivet nuts into the four
1/4-inch mounting holes.
NOTE: When removing the QuadraFlare Warning Lights, inspect
the mounting grommets for wear and replace them as needed.
4. The QuadraFlare Warning Light assembly has five 12-inch
long lead wires, which exit out the back of the unit, for
making electrical connections.
5. Complete the electrical connections as described in the
Electrical Connections section.

Selecting a Flash Pattern
QuadraFlare®
Federal Signal www.fedsig.com
Looking at the back of the unit with the vent hole on your
right, the top of the light is controlled with the red wire and the
bottom is controlled with the white wire. See Figure 3. If the light
has one side with red LEDs, the red wire controls that side and
the white controls the other side (amber, blue, white, green, or
red).
Wiring the QuadraFlare
The Model QuadraFlare Warning Light assembly operates on
12 Vdc. Five 12-inch long lead wires are supplied for making
electrical connections to the QuadraFlare Warning Light
assembly. Ensure that all wires are properly connected and
insulated appropriately.
To make electrical connections:
1. Using 18 AWG (minimum) wire, connect the red (+) lead to
the positive power source terminal and the black (–) lead to
the negative power source terminal.
2. On the QuadraFlare, connect the white (+) lead to the same
positive power source terminal as the red (+) lead to operate
or switch to power up independently of each other.
3. On all models, the violet wire (low power, dimming) is
connected to +12 V power source. Removing the power
restores the unit back to full power.
4. Apply power and test the QuadraFlare Warning Light
assembly for proper operation.
Selecting a Flash Pattern
The QuadraFlare has 26 selectable flash patterns with Pattern 1
as the default. See Table 2 for a description of each pattern and
the order in which it is stored in memory.
To select flash patterns:
1. Remove and retain the four #6 by 2-inch. mounting screws.
2. Apply power to the light.
