Gamewell FCI GFPS-9RB Replacement Board (7 Dip Switch)

The Gamewell-FCI GFPS-9RB distributed power supply replacement board (7 DIP switch version) is a 9A, 24VDC filtered notification power expander PCB with built-in battery charging, supervised NAC expansion, and onboard appliance synchronization. This newest revision uses a 7-position DIP switch bank, where DIP #6 provides built-in sync selections for Faraday, Gentex, System Sensor, and Cooper-Wheelock, and DIP #7 adds AMSECO synchronization for broader appliance matching. Key Specifications: Type: Distributed power supply replacement board / NAC power expander PCB (7-position DIP switch revision) Core Function(s): Provides up to 9A of filtered 24VDC for notification appliances, with battery backup/charging, supervision (AC, battery, ground fault, NAC/AUX faults), Form C trouble contacts, and onboard temporal and synchronization options Power: 120 VAC input; 24 VDC output up to 9A total (nominal) Circuits: Two Class A (Style Z) or four Class B (Style Y) NACs; 3A per NAC, 9A total capacity Indicators/UI: Status LEDs for AC and trouble conditions; 7-position DIP switches for circuit configuration, coded/non-coded behavior, temporal pattern option, auxiliary output behavior, AC-fail reporting delay, and synchronization selections (DIP #6: Faraday, Gentex, System Sensor, Cooper-Wheelock; DIP #7: AMSECO) Trouble Contacts: Dry Form C trouble contacts; AC power failure reporting delay programmable up to 6 hours (disable-capable) Aux Power Output: Power-limited, non-resettable auxiliary output up to 3A; DIP-selectable battery disconnect of AUX output 30 seconds after AC loss to reduce battery drain from high-current loads Battery Charging: Maintains batteries up to 35Ah (larger batteries require an external battery box) Equivalent Product: Silent Knight 5499 – Equivalent 9A distributed power module with the same 7 DIP switch System Compatibility: Used as a fire alarm accessory power expander to add supervised 24VDC NAC power and battery-backed notification capacity to compatible fire alarm control panels.
