INSTALLATION
1. First, install the Strobe Power Supply in a protected location using the power supply itself as a template. THE POWER
SUPPLY MUST BE MOUNTED TO A METAL SURFACE.
Make sure all connectors are easily accessible. The unit is
mounted using the 4 mounting holes on a 6” x 2.5” rectangle
(matches exactly the Whelen UPS Series).

Insert wires with male pins into
the proper locations in the male
AMP connector:

BLACK WIRE - HOLE #2
WHITE WIRE - HOLE #3
2. Install the strobe light heads in the preferred locations.
3. String the 3 conductor cables between the lights and the
power supply. Make sure the cable is secure along the chosen routing inside the vehicle to prevent it from damage by
chafing or binding. Be sure to keep the cable away from engine hot spots.
NOTE
When routing the cable, make sure the end with the
closed tip terminals (male pins) is toward the power
supply and the end with the open tip terminals (female
pins) is toward the light head.
FEMALE AMP CONNECTOR
Insert wires with female pins into
the proper locations in the female
AMP connector:

4. Insert the pins on each end of the conductor cables into
the AMP connectors. Each end of these cables has a factory
crimped pin on each of the three wires, see Figure B.
NOTE
If the special flash options (Double, Quint,
WarpFlash™) are to be used, see “Special Mode”
section.
NOTE
It is important to follow the correct color code when
inserting the pins into the AMP connectors.
5. Connect the cables to the strobe light heads.
6. Next, plug the other end of the cable into the Light Head
Output Socket on the Strobe Power Supply, see Figure A.
The location of the connector for each light head attached to
the unit will be determined by the flash pattern selected, see
Figure E.
7. Plug the Flash Control Wire Harness Assembly into the
Flash Control Input Socket on the Strobe Power Supply. Connect the wires from the Flash Control Wire Harness Assembly to the switch control panel, see “Flash Control Wire Harness Assembly” section.
The Power Wire Harness is connected to the Power Input
Socket located on the Strobe Power Supply, see Figure A. If
necessary, use 18 gauge wire to extend the violet wire to a
customer supplied switching system, see Figure G. Connect
the red wire to the positive (+) side of the battery making sure
to place a customer supplied 15 Amp fuse at the battery.
Connect the black wire to the negative (-) side of the battery or
to vehicle chassis.
NOTE
To extend the power (+) and ground (-) wires, use the
following as a guide.
1 to 10 ft. use 18AWG wire
10 to 20 ft. use 16AWG wire
20 to 30 ft. use 14AWG wire
30 to 50 ft. use 12AWG wire
8. Plug the Power Wire Harness Assembly into the Power
Input Socket. Connect the Strobe Power Supply to the power
source to complete the installation, see “Power Wire Harness
Assembly” section.

The Flash Control Wire Harness Assembly consists of an
AMP 3 pin connector with three wires: yellow, green and
blue, see Figure C. The blue wire controls the light head
outlets 1-4 and the green wire controls the light head outlets 5
and 6. The yellow wire is used for pattern selection.

! WARNING
PERSONAL INJURY HAZARD
Mounting this device in an improper location may
impair the designed safety characteristics of
the vehicle in the event of a collision.
To Reduce EMI emissions, ONE end of the shield (drain wire)
of the extension cable connecting the output of the power
supply to the Lighthead should be connected to ground. Make
sure ONLY ONE END of the shield is tied to ground. The
other end needs to be taped or cut.
Consult the vehicle manufacturer before
installing this or any other aftermarket device to
determine its proper mounting location.
Failure to consult and follow the vehicle
manufacturer’s mounting recommendations
may result in serious personal injury or death.
SPECIAL MODE
To select any one of the different flash modes, simply connect the Yellow, Violet, Blue and Green wires to a switch in the
following combinations. (“POWER” = 10-30 Vdc and “NC/GND” = no connection or ground)

Frequently asked questions

The Strobe Power Supply must be mounted in a protected location using the power supply itself as a template. It must be mounted to a metal surface, using the 4 mounting holes on a 6” x 2.5” rectangle, matching exactly the Whelen UPS Series.

This strobe power supply allows you to select different flash modes, such as Double Flash, Quad Flash, Quint Flash, and WarpFlash™, by connecting specific wires to a switch, allowing you to customize the flashing patterns of the strobe lights.

The power supply comes with a Power Wire Harness Assembly consisting of an AMP 3 pin connector with red, black, and violet wires. Connect the red wire to the positive side of the battery and the black wire to the negative side of the battery or vehicle chassis. The violet wire can be extended to a customer supplied switching system to select different flashing patterns.
