Overview
Overview
The Allegiant
TM
light bar is a single-level LED light bar with ROC
TM
(Reliable On-Board
Circuitry) and Solaris
®
LED technologies. ROC eliminates approximately 85 percent of
potential failure points by incorporating a printed circuit board (PCB) in one assembly
to substantially reduce the number of electrical connections. Solaris S2 LED modules
use offset, complex reflector surfaces for accurate beam-shaping and the highest
optical efficiency. The reflectors’ overlapping, 360-degree lighting eliminates weak
spots and provides off-axis warning around the light bar.
LED Lights, Colors, and Flash Patterns
The microprocessor inside the light bar supplies three priority operational modes
and a library of 27 flash patterns. To increase the safety of officers, pedestrians, and
motorists, light bars larger than 21 inches long have standard front and rear cutoff,
dimming, and intersection warning. The 21-inch light bar has dimming.
Multi-color heads are available with up to two different colored LEDs, eliminating the
loss of primary warning colors in takedown, alley, and directional warning positions.
Individual Allegiant light heads can flash between red, blue, amber, green, or white.
NOTE: The 21-inch light bar does not have directional or alley warning positions.
Electrical System
The Allegiant light bar is protected against reversed polarity damage. The Allegiant
light bar can be installed in any vehicle with a 12-volt negative-ground electrical
system.
Controller Options
Allegiant is configurable for Serial or Discrete control. Serial commands are controlled
through the light bar CAT5 communication cable. The cable connects to Federal
Signal Convergence network controllers, the Serial Interface Module (Part Number
8583446), the Federal Signal Six-Button Serial Controller, or the Federal Signal Three-
Button Serial Controller.
With the Serial Interface Module, the Allegiant light bar can be activated by Federal
Signal light bar controllers, SignalMaster™ directional light controllers, or by individual
low-current switch boxes. Discrete bars larger than 21 inches send commands by a
nine-conductor cable. The 21-inch light bar use a seven-conductor cable.
LOW LIGHT HAZARD: Enabling the Low Power function in the light bar may
cause the light output to fall below certain current light output standards and
guidelines for emergency warning lights. Use extreme caution when using
this function. Ensure that the ambient light conditions are low enough that
you are seen and that the reduction of glare from the light bar is safer than full
light output in the situation. Failure to heed this warning may result in serious
injury or death to you or others in your vicinity.
