An Overview of the CN SignalMaster
™
The CN SignalMaster FSJoin™ 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 CN SignalMaster is available in eight-head and four-
head models, for both front and rear. It is also available in a rear only, split eight-head
model, with a 12 ft cable joining two four-head units (CNSMJ2X4R).
LED Lights, Colors, and Flash Patterns
The light bar’s internal microprocessor 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 dimming and intersection warning. Multi-color
heads are available with up to three different colored LEDs, eliminating the loss of
primary warning colors in takedown and directional warning positions. Individual
CN SignalMaster light heads can flash between red, blue, amber, or white. The
light bar operates at a nominal input of 13.6 Vdc (11 Vdc minimum) and an operating
temperature range of –30°C to +65°C (–22°C to +149°C).
The functions of the SignalMaster are controlled through the CAT5 serial
communication cable. The cable connects to Federal Signal Convergence network
controllers, or the Convergence Serial Interface Module (Part Number 858303641).
With the Serial Interface Module, the light bar can be activated by Federal Signal light
bar controllers, SignalMaster controllers, and/or individual low-current switches.
The housing is an anodized aluminum extrusion. The light bar has 15-foot power and
ground cables and a 25-foot serial cable. Universal mounting hardware is supplied;
vehicle-specific mounting hardware is also available separately.
FSJoin
™
FSJoin light bars allow flash patterns to synchronize with other FSJoin-compatible
devices. You can program light bar patterns and features on an individual light head
basis with the Convergence Network Configuration Software. Outputs or light heads
set to the same flash rate automatically synchronize. You can program a variety of
system features with the Convergence Network Configuration Software (available
on the Federal Signal website at www.fedsig.com). Programming requires an FSJoin-
compatible controller such as a Pathfinde
r
®
Siren/Light Controller. Programming does
not require disassembling or removing any hardware from the vehicle.
