LC-LED MODULES
The LC-LED modules are equipped with one steady burn and three flashing patterns
.
To select a different flash pattern, apply +12 or
+24 VDC to the red wire and connect the black wire to the power supply ground. The unit will flash in whatever pattern was last set.
Change the pattern by momentarily touching the white wire to the power supply ground. The flash pattern will change to the next
pattern according to the following list:
-Steady Burn
-75 FPM Single
-75 FPM Quad
-Cycle
Continue to cycle through the various patterns until the desired pattern is selected. The unit will retain this pattern even when power
is removed. On Dual Color Modules, placing the yellow wire to ground will cause the amber LEDs to steady burn. Placing the black
wire to ground will activate the non-amber LEDs. Most lightbars using Dual Color LCLED modules will be wired using a relay that
allows power switching to activate the non-amber portion of the unit.
Note: The white flash pattern selection wire must be
protected from contact with the system ground to prevent inadvertent changes to the flash pattern. This can be accom-
plished by sealing or capping the end of the wire.
Note: Regardless of the location in the program in the flash pattern list, the unit
can be forced to steady burn by permanently electrically tying the white wire to the black wire.It is recommended that all heads be set
to the desired pattern at a workbench prior to installation.
