Silent Knight 5499 Replacement Board (6 Dip Switch)

The Silent Knight 5499 distributed power module (6 DIP switch version) is a 9A, 24VDC filtered notification power expander with built-in battery charging and supervised NAC expansion for adding notification power capacity to a fire alarm system. This revision uses a 6-position DIP switch bank, where DIP #6 adds built-in sync selections for Faraday, Gentex, System Sensor, and Wheelock; it does not include DIP #7, so AMSECO sync is not available on this version. Key Specifications: Type: Distributed power module / NAC power expander (6-position DIP switch revision) Core Function(s): Provides up to 9A of filtered 24VDC notification power with battery backup/charging, supervision (AC, battery, ground fault, NAC/AUX faults), a Form C trouble relay, and built-in cadence options across four power-limited NAC outputs Power: 120 VAC input; 24 VDC output up to 9A total; 3A max per NAC output circuit; includes continuous auxiliary output; supports batteries up to 35Ah charging capacity Indicators/UI: AC power LED (green); Battery Trouble, Ground Fault, Aux Trouble, and Output Trouble LEDs (yellow); 6-position DIP switches for circuit configuration, Class A/B selection, auxiliary behavior, AC-loss delay options, cadence selection, and built-in sync selections (DIP #6: Faraday, Gentex, System Sensor, Wheelock; no DIP #7 for AMSECO) Equivalent Product: Gamewell FCI GFPS-9RB – Equivalent 9A distributed power replacement board with the same 6 DIP switch System Compatibility: Compatible with fire alarm control panels that provide reverse-polarity supervised NAC outputs (9–32 VDC signaling) for triggering, while the 5499 provides the downstream 24VDC notification power and supervision.
