The Guardian™ Power Supply:
If your lightbar comes equipped with the Guardian™ strobe power
supply, you will have a choice of 10 changeable flash patterns. This
power supply also comes with a Hi/Low feature to switch the beacons
from high to low power. These features are only available on
permanent mount models.
Wiring:
WARNING! The strobe light power supply is a high voltage
device. Do not touch or remove tube assembly in strobe light
head assemblies while in operation. Wait 10 minutes after
disconnecting the unit from its power source before starting
work or troubleshooting on power supply or system.
WARNING! All customer supplied wires that connect to the
positive terminal of the battery must be sized to supply at
least 125% of the maximum operating current and FUSED at
the battery to carry that load. DO NOT USE CIRCUIT
BREAKERS WITH THIS PRODUCT!
Note: All fuses and fuse blocks are customer supplied
1. Extend the 4 wires exiting the lightbar to the designations
shown in figure 4.
2. Connect the RED wire to a fuse block (customer supplied) and
then to the POSITIVE terminal on the battery. Do not install the
fuse until ALL of the wire connections are completed. Refer to
the wiring diagram for the appropriate fuse value needed.
3. Connect the black wire to the factory chassis ground typically
adjacent to the battery.
Low Power Control / Violet:
The type of switch used depends on how the operator wishes the Hi/
Low feature to function:
Latching Mode: By applying +voltage to the VIOLET power supply
wire for less than 1 sec., the power supply is “latched” into low power
operation. The unit must be turned off and then back on to restore
normal, Hi power operation. A momentary switch is desired for this.
Level Mode: Applying +voltage to the VIOLET power supply wire for
more than 1 sec. holds the power supply in low power mode until that
voltage is removed. A toggle switch is desired for this.
Pattern Selection / White:
This is a positive activation input. A momentary activation (less than 1
second) of the WHITE wire will change the default flash pattern to the
next available pattern. If the new pattern is active for more than 1
second, it will become the new default pattern. A momentary activation
(more than 1 second) will cause the power supply to change the
default flash pattern to the previous available pattern. If the input is tied
to positive while the unit is powered up, the default pattern will change
to CometFlash®.
