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 be sure 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.
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 be sure the lights flash properly and
all light system functions operate properly.

INSTALLATION PRECAUTIONS: The warning system and/or two-way radio system
may operate improperly if a two-way radio antenna is installed on or within
18 inches of the light bar. Before permanently installing the light bar or a two-
way radio antenna, test the warning system and two-way radio system. Some
installations may require the relocation of the two-way radio antenna to the trunk
or fender. DO NOT drill holes in the light bar or install auxiliary devices on the light
bar, or the warning system may fail.
LOCATING OPERATOR CONTROLS: The controls for the light system must be
located so that the VEHICLE and CONTROLS can be operated safely under all
driving conditions.
REVERSE POLARITY/MISWIRING: Reverse polarity may damage the siren
amplifier. To avoid damage to the siren/amplifier, ensure that the battery voltage
is the same voltage as the rating of the light and that the correct polarity is
observed.
Before proceeding, ensure that the light bar has been installed inside the vehicle in
accordance with the instructions included with the mounting kit.
