To restore the Factory Default Flash Rate to a module group, apply +power to the level you wish to change (see Table 2), then hold the ap-
propriate rate selection wire and the BLK/RED wire to +power for more than four seconds. The four corner light heads will flash once, and
then stay on to indicate that the Factory Default setting has been restored.
For instructions related to the California Title 13 steady burning red warning lamp requirement during level mode operation, please contact
ECCO directly.
Emergency Mode Flash Pattern Selection – Synchronized
The seven customizable emergency flash pattern modes in Table 3 each have the option to be synchronized. This condenses the module
groups from TABLE 5 to front and rear.
To synchronize a set of module groups:
1. Power-up the Lightbar and apply +power to the appropriate level mode wires (see Table 3) and the BLK/RED Pattern select wire in
the 16 conductor cable.
2. Momentarily touch the RED wire to +power set the level mode to synchronized. The four corner modules will turn on each time the
lightbar is toggled between unsynchronized and synchronized.
Once synchronized, the module group in each mode flash sequence defaults to OFF. To change a light head group flash sequence
selection:
1. Power-up the Lightbar and apply +power to the appropriate level mode wires (see Table 3) and the BLK/RED Pattern select wire in
the 16 conductor cable.
2. Momentarily touch the appropriate light head group wire, shown in Table 7, to +power to cycle through the sequences shown in shown
in Table 7.
