Testing the Light Bar
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.
EXPLOSION HAZARD: To avoid a battery explosion, always disconnect the
negative battery cable first and reconnect it last. Avoid causing a spark when
connecting near or to the battery. The gases produced by a battery can cause
a battery explosion that could result in vehicle damage and serious injury.
To check the light bar controls (see “Table 2 CN SignalMaster controls and wires from
the Serial Interface Module” on page 12):
1. Connect the 16 AWG black lead from the light bar to the vehicle battery’s ground
(–NEG) terminal 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
vehicle battery’s ground (–NEG) terminal
3. Apply 12 Vdc to a control wire and to the ignition wire from the Serial Interface
Module.
4. After the installation, check the entire system to verify that the lights are flashing
properly and all light system functions are operating properly.
