3.
Remove 12 Vdc from the MODE 2 control wire.
Mode 1
1.
Apply 12 Vdc (+BAT) to the MODE 1 control wire (blue) from the Serial Interface Module
to display the assigned pattern.
2.
On the Serial Interface Module, press and release the SW-1 button until the pattern
you want appears on the light bar.
3.
Remove 12 Vdc from the MODE 1 control wire.
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 5 on page 15) 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.
1.
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.
2.
On the Serial Interface Module, press and release the SW-1 button until the pattern
you want displays on the light bar.
3.
Remove 12 Vdc from the MODE and INTERSECTION control wires.
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.
To change from HIGH to TAP II or 8-SECOND TIMEOUT:
1.
Unplug the 24-pin harness from the Serial Interface Module.
2.
On the Serial Interface Module, set Switch 7 and Switch 8 on SW-2 to select a method
of operation (Table 6). Each setting is independent of the other.
3.
Plug the 24-pin harness into the Serial Interface Module.
