functions installed in your light bar. Switch current
capacities should be at least 15 amps.
NOTE
Any of the light bar functions can be activated
by applying 12VDC to the appropriate control
line. The heavy black lead (-) must be connected
to vehicle ground, to perform a function check.
C. Connect the black lead to chassis ground.
WARNING
If wires are shorted to the vehicle frame or
each other, high current conductors can
cause hazardous sparks resulting in
electrical fires and molten metal.
Verify that no short circuits exist before
connecting to the Positive (+) battery
terminal.
DO NOT connect this system to the vehicle
battery until ALL other electrical connec-
tions are made and mounting of all compo-
nents is complete.
Failure to observe this WARNING will
result in fire, burns and blindness.
D. Connect the light bar’s red power lead to a fuse
or circuit breaker rated at 20 amperes. Connect the
other side of the fuse /circuit breaker to the +12VDC
supply.
E.
Flasher (see figure 3).
1.
General.
The flasher has two (2) light circuits with a
current capacity of up to 10-amperes (maximum) per
side, 20-amperes total. The flasher is designed to
operate on any 12VDC (negative ground) vehicle
electrical system. The flasher operates as a high side
switch, switching the +DC supply to the load.
2.
Wiring.
CAUTION
The device WILL NOT light up or flash if
improperly grounded. Be sure that the device
ground is attached to a good vehicle ground. A
ground termination at the flasher is provided.
Refer to figure 3 when performing the
following procedure.
The flasher has two outputs, Out 1 and Out
2. These outputs switch the +DC source from source to
the load.
WARNING
To provide safe operation, the user sup-
plied power control switch and wiring
must be capable of handling the rated
current of the fuse at the source.
3.
Programming.
The flasher will provide the end user with
two preselected flash patterns. The preselected flash
patterns are to be chosen from the ten factory pro-
grammed patterns provided with each flasher. It is
recommended that the preselected flash patterns be
determined and programmed during installation.
The red/green LED as indicated in figure 1
will be illuminated green when an SAE approved flash
pattern is selected. When an unapproved SAE flash
pattern is selected, the LED will be illuminated red. The
red/green LED may alternate between red and green for
several flash patterns.
The following procedures demonstrate the
programming and operating features of the flasher:
