Controller (77520)
The optional in-cab controller provides convenient control of the Lightbar’s 24
built-in flash patterns and features soft touch buttons and LED function indicator
lights.
Controller Operation
The 26 series controller consists of 7 buttons with 6 LED indicators. When one of the 5 lower buttons is pressed, the corresponding indica-
tor will illuminate (2 center ones for WL function) and then turn OFF if pressed again. There are two large flash pattern preset buttons. The
“OFF” and “SEL” buttons do not have illuminated indicators.
“OFF”
- Turns the whole bar off. This is a quick way to shut everything down. Each of the 5 features can also be shut down
individually by pushing the feature’s button.
“Program I, Program II”
- Controls which Program turns on the warning modules (see “SEL” to change the pattern of the
Program). Only one Program can be selected at a time. If one is already on when the other is selected, it will shut the
first one off.
“AL”
- Controls the left alley light
“AR”
- Controls the right alley light.
“WL”
- Controls the center pair of takedown or worklights.
“SEL”
- Changes the flash pattern for whichever Program is currently running.
