An Overview of the Reliant Light Bar
The Reliant
™
light bar is a single-level LED light bar with ROC (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 flash patterns. To increase the safety of officers, pedestrians, and motorists, the
light bar has standard front and rear cutoff, dimming, and intersection warning.
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
Reliant light heads can flash between red, blue, amber, or white.
Electrical System
The Reliant light bar is protected against reversed polarity damage. The Reliant Light
Bar can be installed in any vehicle with a 12-volt negative-ground electrical system.
Controller Options
Flash patterns are controlled through the light bar CAT5 communication cable. The
cable connects to Federal Signal Convergence network controllers or the Serial
Interface Module (Part Number 858303641).
With the Serial Interface Module, the Reliant Light Bar can be activated by Federal
Signal light bar controllers or by individual low-current switch boxes.
Other advanced features of the Reliant light bar include:
• A high degree of reliability through the use of advanced microprocessors and other
integrated circuits.
• High output, long-life LEDs with no bulbs to change.
