INSTALLATION
1. First, install the Q450 Strobe Power Supply in a protected
location using the power supply itself as a template. THE
POWER SUPPL Y MUST BE MOUNTED TO A MET AL SURFACE. Make sure all 3 position socket 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).
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.

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.
The Flash Control Harness assembly must be connected to
the control socket located on the Q450 Strobe Light power
supply, see Figure E and Figure A. Use 18 gauge wire to
extend the control harness wires to a customer supplied switch
to complete the installation.
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
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 Flash Control Wire Harness assembly to
the switch control panel (see “Flash Control Wire Harness
Assembly” section).
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).
POWER WIRE HARNESS ASSEMBLY
The power wire harness is connected to the power input socket
located on the Q450 Strobe Power supply, see Figure A and
Figure E. The power wire harness assembly consists of red
and black wires (see Figure D) that power the strobe power
supply (see Figure A) and a violet wire that controls the day/
night (high/low) intensity feature of the power supply (see Figure G).
The high/low intensity feature allows the strobe lights of the
system to be switched into low power or reduced intensity.
This feature is useful for night time use. When the violet wire
is powered with (+) 12 volts, the power supply is switched to
low intensity. When power is removed, the power supply
switches to high intensity mode. If the high/low feature is not
wanted, simply do not install the violet wire, see Table for
exception.
FLASH CONTROL WIRE HARNESS ASSEMBLY
The Flash Control Wire Harness assembly consists of an AMP
3 pin connector with 3 wires: green, blue and yellow (see Figure C or Figure E). The green wire controls the strobe light
outlets 1 and 4. The blue wire controls the strobe light outlets
2 and 3. For a standard Quad flash installation, the yellow
wire is not used and can be removed.
NOTE
If the special flash options (WarpFlash™, Quint,
Double) are to be used, the yellow wire is needed and
the blue and green wires take on different functions,
see “Special Mode” section.

SWITCH CONTROL OPTIONS
Figures F and G show some of the standard switch control
options that can be easily wired to complete a Strobe Light
system.
Figure F , ALL HEADS ON HIGH POWER ONLY . This wiring
diagram shows an on/off control system that powers all four
heads.
Figure H shows how any flash option could be installed depending on which control wire(s) are attached to the switch.
All high power flash patterns, with the exception of patter #16,
can be easily selected with a single binary switch encoded
rotary switch (
SoundOff Signal part #PEPBE2).

T o 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.
