Emergency Mode Flash Pattern Selection
There are seven customizable emergency flash pattern modes available based on the wire combinations shown in TABLE 3. When using
individual switches, make sure to configure all possible switch combinations. The default setting is unsynchronized which allows each light
head module group to be configured separately and the lightbar to flash in an unsynchronized pattern. Steps to synchronize the light head
module groups together are detailed in later sections.
The module groups in each mode come with the default flash patterns shown in TABLE 4.
To change a light head group flash pattern selection:
1. Power-up the Lightbar and apply +power to the level mode wire you wish to change (see TABLE 3). The light bar will flash the default
pattern shown in TABLE 4.
2. Twist together the BLK/RED Pattern select wire in the 16 conductor cable and the wire of the light head group you want to change shown
in TABLE 5.
3. Momentarily touch the BLK/RED and group wire from step 2 to power to cycle through the patterns in TABLE 6. The pattern
for the set of light heads configured will only be set in the level mode selected.
