Intersection
The INTERSECTION flash pattern overrides all three priority modes when
activated. To select a new pattern, you must apply 12 Vdc to the control wire for
either MODE 1, 2, or 3 (Table 9 on page 20) and the blue/black control wire for
INTERSECTION.
NOTE:
This procedure only programs the INTERSECTION pattern.
It does not assign
the pattern to a MODE.

Apply 12 Vdc (+BAT) to a control wire for either MODE 1, 2, or 3, and the control
wire for INTERSECTION from the Serial Interface Module.

On the Serial Interface Module, press and release the SW-1 button until the
pattern you want displays on the light bar.

Intersection Operational Settings
Select one of three options to turn on the INTERSECTION pattern:
• HIGH with +BAT power maintained (default): The light bar displays the
INTERSECTION pattern until power is removed.
• TAP II (push-on/push-off): The INTERSECTION flash pattern is turned on and off
by pressing a momentary contact switch, such as a horn button. Momentary 12
Vdc turns on the pattern, a second momentary 12 Vdc signal turns it off.
• 8-SECOND TIMEOUT activated by +BAT: Momentary 12 Vdc turns on the
INTERSECTION flash pattern for eight seconds.
