1.Mounting:
Mount the power supply to a flat metal surface.
Mount in a clean, dry area. NEVER MOUNT IN ENGINE COMPARTMENT! Use the power supply as a template to mark the hole
locations. The mounting holes will accept up to a 1/4” bolt.
Note: The power supply baseplate must be connected to chassis
ground (GND) to reduce radio interference.
2.Strobe Head Installation:
Plug the strobe light heads into the outlets.
• Heads connected to outlets 1, 3, 5 flash at the same time.
• Heads connected to outlets 2, 4, 6 flash at the same time.
• Heads connected to 1, 3, 5 alternate with heads 2, 4, 6.
• Be sure to use strobe heads with the correct power rating.
The total output power (60 Watts) of the NOV-669 is distributed to
the strobe head as follows:
1 Head installed and activated
= 30 Watts.
2 Heads installed and/or activated= 30 Watts per head.
3 Heads installed and/or activated= 2 heads at 15 Watts each, 1 at 30 Watts.
4 Heads installed and/or activated= 15 Watts per head.
5 Heads installed and/or activated= 3 heads at 10 Watts, 2 at 15 Watts.
6 Heads installed and/or activated= 10 Watts per head.
3.Electrical Hookup:
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.
POWER HARNESS:
• 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.
Note: Use the correct size wire for power connections. The length
of the wires determines the size needed.
1 to 10 ft. use 18AWG wire.
10 to 20 ft. use 16AWG wire.
20 to 35 ft. use 14AWG wire.
35 to 50 ft. use 12AWG wire.
• The VIOLET wire activates LOW power. The output power is
reduced to 40 Watts in LOW power mode. Connect VIOLET to
+12/24V to activate LOW power mode, leave disconnected or connect to GROUND for high power mode.
CONTROL HARNESS: DO NOT CONNECT ANY OF THESE
WIRES TO THE HIGH VOLTAGE STROBE OUTLETS!
YELLOW: Flash pattern selection. Momentarily connect to
+12/24V to advance to the next flash pattern in the PATTERN
LIST. Momentarily connect for 3 seconds to reset to pattern #1.
The flash pattern will be retained when the NOV-669 is turned off
or if the power is removed. To change flash patterns frequently,
connect YELLOW to a momentary pushbutton located in the passenger compartment.
GREEN: Activates Heads 1 & 2 when connected to +12/24V.
BLUE: Activates Heads 3, 4, 5 & 6 when connected to +12/24V.
Note: VIOLET, YELLOW, GREEN and BLUE are all Low Current
circuits and can be wired with a minimum of 22AWG wire.

Momentarily connect YELLOW wire to +12/24V to advance to the next
flash pattern in the list below. (Or use pushbutton if you installed one.) The
flash pattern loops back to pattern #1 when it is advanced past #15. If you
are unsure of which flash pattern is currently selected, connect and hold
YELLOW to +12/24V for 3 seconds to reset to flash pattern #1.

• The EZ PANEL connector is only for use with the EZ PANEL series of control panels.
• Do not connect both the EZ PANEL cable and the
standard control wires at the same time!
• Do not connect any other devices to the EZ PANEL
connector as permanent damage may result.
• Use only approved cables with the EZ PANEL.

INPUT
INDICATOR
NORMAL: The OUTPUT INDICATOR will light when ANY strobe head
fires. It will blink in exact time with the flash pattern. When the NOV-669 is
turned off the indicator may dimly blink for a few seconds. This indicates
that the power supply is discharging itself.

PROBLEM: If the NOV-669 is activated but none of the strobe heads are
firing, check the OUTPUT INDICATOR. If the light is blinking or on steady
then it indicates that there is a short circuit on one or more of the strobe
head outputs.
To find the short circuit, unplug all strobe head cables from the NOV-669.
Test one cable/head at a time until the problem is found. Do not test with
more than one cable/head installed.
The problem is typically at the strobe head end of the cable. If there is a
blue/green or black colored corrosion on the connector it is shorted.
Also check for a head or cable with a reverse wired connector.
INPUT INDICATOR(GREEN)
NORMAL: The INPUT INDICATOR should NOT be lit during normal operation. It may blink for a second when power is first applied to the NOV-669,
or when power is removed but this does not indicate a problem with the
power supply.
PROBLEM: If the NOV-669 is activated but none of the strobe heads are
firing, check the INPUT INDICATOR. If it is ON then it indicates that the
input voltage is too low (below 10V).
There may be a bad connection to the battery or ground. If the NOV-669
is functioning but the INPUT INDICATOR is blinking or lit it indicates that
the voltage is too low and the power supply is not operating at full power.
Check for bad connections and be sure the proper size wire was used for
the + and - connections.
BLOWN FUSE
The NOV-669 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. If the fuse continues to blow it indicates an internal fault. Do
not use a larger than 15A!
