The Gentex GSSR (Synchronization Splitter Relay) lets a single master sync source or compatible fire alarm control panel drive Gentex strobes, horns, and horn/strobes across multiple notification appliance circuits at once. It's built for large installations where a NAC needs to be expanded or split into additional circuit runs while every appliance still holds the strict 1 Hz flash synchronization that ADA and NFPA 72 require.
