Programming the Discrete-Wire SIFM ILS
The white programming wire enables you to program the functions of the control wires. A
description of each function is listed in Table 4. Only one control wire can be modified at a
time. If more than one control wire is active, the programming wire is disabled.
To modify the function of a control wire:
1. Connect the black wire from the light bar to ground (–GND), then apply 12 Vdc (+BAT)
2. Cycle through functions by tapping the white programming wire from the light bar to
3. To save the setting, let the function run for five seconds before removing power. The
