The Model SSM, Synchronous Strobe Module, is an electronic timing mechanism designed to energize select Federal Signal low in-rush 24VDC strobe lights simultaneously, while maintaining the ability to remotely supervise the strobe light circuit. This module is designed to synchronize a special series of Federal Signal strobe lights, which meet the requirement for Private-Mode Fire Alarm use, while maintaining the agency approval and environmental rating of the strobe light. The SSM is only compatible with Federal Signal brand strobe lights.
