GST DC-M9410 Signal Synchronization Module

The GST DC-M9410 is a compact signal synchronization module designed to deliver precision timing for connected sounders and strobes across a Notification Appliance Circuit (NAC). Engineered to ensure fire alarm system compliance with UL 1971 signaling requirements for the hearing impaired, this module unifies the activation of downstream notification appliances so that visual strobes flash in unison (1 flash per second) and audible appliances sound synchronized temporal patterns. It handles up to a 3.0A output rating on standard 24VDC or 24VFWR NAC lines, ensuring that all downstream devices maintain strict lockstep operation without additional complex system programming. Built with a compact form factor that fits directly inside a standard single-gang electrical box, the DC-M9410 provides a reliable and space-saving synchronization solution for GST notification appliance networks.
