The WARN function provides a non-directional flash pattern for use when a directional signal may not be
appropriate. One pattern can be selected from the 16 patterns available, which include 13 standard patterns
and three patterns compliant with CAC Title 13, Article 22. Some patterns are optimized for LED products
and flash too fast for a halogen lightbar. The default pattern is the classic SMC warn pattern with the center
lightheads alternating with the lightheads on each end.
The AUX function provides an installer-selectable flash pattern for two auxiliary light heads. The AUX
function operates external lamps (if installed) independently only if one of the five available patterns other
than Pattern 6 (all on) or null is selected (Table 6 on page 11.) Each of the two auxiliary channels can flash a
55 W load. A pattern with the outputs set to remain on constantly is available. This will allow a pair of strobe
beacons or similar devices with an internal flasher to be turned on by using the AUX switch.
This controller also incorporates a turn signal override. When each of the override inputs for the turn signal is
wired directly to the respective turn signal circuit of the vehicle, the appropriate end module flashes in sync
with the turn signal or hazard lights. When connected, the turn signal feature overrides any other function
of the Model 331105, shutting off the directional lightbar during the turn, and returning to the previously
active pattern when the turn signal is cancelled. These inputs activate with a connection to positive 12 Vdc to
24 Vdc. They should be left disconnected when not needed.
When standard directional signal operation is selected, the lamps illuminate sequentially in a sweeping
