LOW POWER

Red
Dims the lights approximately 50 percent
to prevent blinding approaching drivers.
LOW POWER is only available in MODES
1 and 2 and is disabled when switched to
another flash pattern, including MODE 3 and
INTERSECTION.

Entering Program Mode
To switch the module from Operation Mode to Program Mode:
1.
Unplug the 24-pin harness from the Serial Interface Module.
2.
On the Serial Interface Module, move Switch 6 on SW-2 to the down (ON) position.
3.
Plug the 24-pin harness into the Serial Interface Module.
NOTE:
When you press and release the SW-1 pushbutton on the Serial Interface Module to select a
pattern, the lightbar briefly turns off and then displays the next pattern. To cycle backwards to a previous
pattern, move Switch 5 to ON (up position) on SW-2.
SW-2 DIP Switch Settings in the Serial Interface Module
For the location of SW-2, see Figure 3.2 on page 15. Table 3.1 on page 15 lists the DIP switch settings in
the Serial Interface Module for programming flash patterns.
Programming Priority MODES 1, 2, 3, and INTERSECTION
The three modes operate with MODE 3 having the highest priority: MODE 3 overrides MODE 2, and
MODE 2 overrides MODE 1. When the lightbar operates in one of these modes, the SignalMaster
modules keep sequence with the flash pattern.
You can change default MODE flash patterns by programming each mode with one of 26 patterns in the
lightbar’s library. A typical setup would be:
• MODE 1: REAR LEDs
• MODE 2: FRONT/REAR LEDs
• MODE 3: Siren (SmartSiren
®
or Federal Signal compatible), and FRONT/REAR LEDs and FLASH
TAKEDOWN/ALLEY LEDs on the mainbar
• MODES 1 and 2: FRONT/REAR CUTOFF
NOTE:
If you are reprogramming the lightbar after you have connected a progressive slide switch, the
programming sequence must be MODE 3, MODE 2, MODE 1, INTERSECTION.
