Federal Signal Serial Interface Module FSJoin® Programmable

The Serial Interface Module provides seamless communication with Federal Signal Convergence Network (serial)-compatible light bars, ILS systems, and CN SignalMaster™. It allows first responders to efficiently control multiple in-vehicle systems—such as lighting, sirens, radios, and more—from a single interface. This centralized control enhances operational efficiency, simplifies system management, and reduces the need for manual operation of individual devices, enabling responders to stay focused on mission-critical tasks.
