Programming the Discrete-Wire SIFZ ILS
Programming the Discrete-Wire SIFZ 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) to the 16 AWG red wire and the wire you want to modify.
2.
Cycle through functions by tapping the white programming wire from the light bar
to 12 Vdc (+BAT).
3.
To save the setting, let the function run for five seconds before removing power.
The available programming functions are listed in Table 4.

Testing the Serial SIFZ ILS Controls
LIGHT HAZARD: To be an effective warning device, an emergency warning
system 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.
NOTE:
After the installation, check the entire system to ensure that the lights are flashing
properly and all light systems are operating properly.
To test the light bar controls:
1.
Connect the 16 AWG black lead from the light bar to the ground (–NEG) terminal of
the vehicle battery and the 16 AWG red lead to the positive terminal.
2.
Connect the black and black/white wires from the Serial Interface Module to the
ground (–NEG) terminal of the vehicle battery
