Warning and Traffic Clearing LED Light Built for First Responders
CN SignalMaster™ provides advanced warning and directional lights specifically for police cars, fire trucks, and work trucks. Built with Federal Signal’s exclusive Solaris® LED reflector design for superior light intensity, the CN SignalMaster is available in 4-, 8-, and split 8-head models. All models are suitable for interior and exterior installation.

Split 8-head models are synchronized to operate as one unit. These models are ideal for mounting externally on a Dodge® Sprinter, Chevrolet® G-Van, or Ford® Transit and can also be mounted on popular police vehicles.

Eye-Catching Patterns In a Variety of Colors
The CN SignalMaster can quickly be changed from a warning light to a directional light with Federal Signal’s Spectralux® technology. SpectraLux multicolor LED technology allows for a single LED source to change while in motion. CN SignalMaster is available in color combinations of Amber, Blue, Green, Red, or White.

White LED options can be used as takedowns, work lights, or act as an impressive floodlight. Rear-facing models have a built-in SignalMaster to act as a directional light for oncoming traffic.

CN SignalMaster Options

Simple Installation and Programming
CN SignalMaster models are equipped with the FS Convergence Network for simple ‘plug-and-play’ installation and programming. Utilizing standard RJ45 connections, the CN SignalMaster can easily be programmed with Federal Signal Convergence Network sirens.

A serial interface module with your existing light controller can also be used to program and operate the features and functions of the CN SignalMaster.

CN SignalMasters are programmed with (27) built-in flash patterns and can remain in sync with other light head flash patterns or operate independently.
