1.
First, install the Q450 Strobe Power Supply in a protected location using the power supply itself as a template. THE
POWER SUPPLY MUST BE MOUNTED TO A METAL SUR-
FACE. 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.
FEMALE AMP CONNECTOR
Insert wires with female pins into the proper locations in the female
AMP connector:

Figure B
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.
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).
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.
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.
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.

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 G, ALL HEADS ON WITH HIGH AND LOW POWER
CONTROL. This wiring diagram shows a high/low 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).
