1. Physical Mounting
2. Strobe Head installation
Mount the power supply in a clean, dry location. Mounting the
unit to a flat metal surface will aid in heat dissipation. Use the
power supply as a template to mark the hole locations. The
mounting holes will accept up to a 1/4" bolt.
Plug the strobe light heads into the outlets. Keep the following in
mind:
• Heads connected to outlets 1, 3, 5 flash at the same time.
Note: The power
supply baseplate must be connected to chassis ground (GND) to
reduce radio interference.
• Heads connected to outlets 2, 4, 6 flash at the same time.
• Heads connected to 1, 3, 5 alternate with heads 2, 4, 6.
The divides equally between all strobe heads
installed. Example: 90 Watts into 2 heads = 45 Watts per head.
Consider this before selecting the number and type of strobe
heads to install. Do not exceed the wattage rating of the head.
If you have purchased a pre wired switch harness, follow the
included instructions. If you are wiring the system yourself
follow the instructions below and the diagrams on the next page.
• Connect the RED wire to battery positive (+) or a fuse panel
circuit rated for at least 15 AMPS.
• Connect the BLACK wire to battery negative (-) or directly to
vehicle chassis.
• The VIOLET wire controls HIGH / LOW power. Low power
limits the flash intensity for nighttime use. Connect VIOLET to
+12/24V for LOW, leave VIOLET disconnected for HIGH.

Note: Use the correct size wire for power connections.
The length of the wires determines the size needed.
1 to 7 ft. use 18AWG wire.
7 to 14 ft. use 16AWG wire.
14 to 25 ft. use 14AWG wire.
25 to 35 ft. use 12AWG wire.
Note: VIOLET, YELLOW, GREEN, BLUE, WHITE, and ORANGE are all
circuits and can be wired with a minimum of 22AWG wire.Low Current

switches. Choose flash pattern from chart.
Selecting a flash pattern: In the table below, find the desired
flash pattern. Connect the wires marked to the
'load' side of the ON/OFF switch.
Example: To use pattern #8 (Quad Flash, All Heads), connect
the YELLOW, GREEN and BLUE wires to POWER.

Blown Fuse
Erratic behavior (and/or) shutdown
: The 21.7690 will blow a fuse if the input
voltage is reversed. If this happens, first locate the wiring
fault, then replace the fuse with one of the same rating.
: The 21.7690 will
shut down if there is a short circuit condition on any one of
the strobe heads. If the electrical conductors connecting
the power supply to the strobe heads are exposed to water
a short circuit will result. The first sign is intermittent
operation, followed by complete shutdown of the strobe
system. To find the short circuit, unplug all strobe head
cables from the 21.7690. Test cable/head at a time
until the problem is found.
