Programming the Light Bar
LIGHT HAZARD:
To be an effective warning device, this product produces bright light that can be
hazardous to your eyesight when viewed at a close range. Do not stare directly into this lighting
product at a close range, or permanent damage to your eyesight may occur.
Before permanently installing the Serial Interface Module (described on page 8), test and program the
light bar. Each mode patterns is programmed independently. If you want to program the light bar after you
connect a progressive slide switch, the programming sequence must be MODE 3, MODE 2, MODE 1, and
then INTERSECTION.
A number of different flash patterns are available for the three modes of light bar operation. When you use
the SW1 flash pattern button, the light bar momentarily turns off before flashing the next pattern. To cycle up
or down through the flash patterns, set SW2 Switch 5 as shown in Table 1 on page 3.
In addition, the FRONT/REAR light heads can be set for +BAT cutoff or enable. The INTERSECTION mode
has one of three options: HIGH (+BAT maintained), TAP II (push-on/push-off) or an 8-SECOND TIMEOUT.
The SignalMaster
®
can also be set for INTERNAL or EXTERNAL control. See Table 1.
