CN SignalMaster Replacement Parts & Accessories

Federal Signal CN SignalMaster replacement parts and accessories, including ROC LED circuit boards, FSJoin control modules, universal mounting brackets, and vehicle-specific mounting kits. Designed for servicing, repairing, and installing compatible CN SignalMaster LED directional warning lights.

Product Description

The Federal Signal CN SignalMaster Replacement Parts & Accessories collection provides a range of replacement components, control modules, and mounting hardware for compatible CN SignalMaster LED directional warning lights. Designed for law enforcement, fire, EMS, and other public safety applications, these products support the maintenance, repair, and installation of Federal Signal emergency vehicle warning systems.

Available components include Reliable Onboard Circuitry (ROC) LED replacement boards, FSJoin control boards, universal mounting brackets, and vehicle-specific installation kits. These accessories allow installers and service technicians to replace individual components, restore existing equipment, or modify mounting configurations without necessarily replacing the complete warning light assembly.

ROC LED Replacement Boards

Federal Signal's Reliable Onboard Circuitry (ROC) technology integrates LED warning modules and electrical connections into printed circuit board assemblies, reducing traditional wiring connections and potential failure points. Replacement ROC LED boards are available for compatible front-facing and rear-facing CN SignalMaster configurations.

Depending on the model, replacement boards support different LED color configurations, including single-, dual-, and tri-color warning combinations. Configurable replacement boards allow customers to select supported LED arrangements to match existing equipment or accommodate specific operational requirements.

FSJoin Control Board Replacements

Replacement FSJoin master and follower control boards are available for compatible CN SignalMaster systems. These electronic components support communication and coordinated operation with compatible Federal Signal Convergence Network sirens and lighting controllers.

The appropriate replacement control board depends on the existing CN SignalMaster configuration and the specific component being serviced. Customers should verify the installed control board type and compatibility before ordering.

Mounting Brackets and Installation Accessories

Federal Signal offers a variety of mounting solutions designed to accommodate different CN SignalMaster configurations and emergency vehicle installation requirements. Available accessories include universal mounting brackets, internal mounting kits, and vehicle-specific mounting hardware.

Universal mounting brackets provide installation flexibility for compatible light assemblies, while vehicle-specific mounting kits are designed to accommodate designated vehicle platforms and mounting locations. These options help installers achieve secure, professional installations while minimizing unnecessary vehicle modifications where applicable.

Compatibility and Replacement Considerations

CN SignalMaster replacement parts and accessories are application-specific. Compatibility may vary depending on the warning light model, front or rear configuration, LED color arrangement, control board type, and vehicle mounting requirements.

Before ordering, customers should verify their existing CN SignalMaster configuration and select the appropriate replacement component or mounting accessory.

Whether maintaining an existing emergency warning system, replacing damaged components, or modifying a vehicle installation, Federal Signal CN SignalMaster replacement parts and accessories provide practical solutions for keeping compatible warning equipment operational.

Individual replacement components and mounting accessories are sold separately. Complete CN SignalMaster light assemblies are not included unless specifically stated otherwise.
