Information About FCPS-24S6RB
The FCPS-24S6RB is a 6-amp member of Notifier’s FCPS-24S Series of remote power supplies. It can follow or generate synchronization for System Sensor, Wheelock, or Gentex strobes and may operate as a NAC expander tied to any 12/24 V FACP or as a stand-alone 24 V supply. The unit provides four NAC outputs configurable as Class B (Style Y) or Class A (Style Z with ZNAC-4 module), plus an integral charger supporting up to 18 AH batteries. A Form-C trouble relay, earth-fault detection, and flexible resettable/non-resettable output modes support code-compliant installations.
Key Features:
- 6-Amp Output: Delivers up to 6 A total in NAC expander mode; 4 A continuous in stand-alone operation.
- Four NACs, Class A/B: Four Class B outputs or two Class A (or four Class A with ZNAC-4 expander).
- Strobe Synchronization: Built-in sync for System Sensor, Wheelock, and Gentex appliances; sync follower or generator modes.
- Wide Panel Compatibility: Works with virtually any UL 864 FACP using reverse-polarity NACs; 9–32 VDC trigger.
- Integrated Battery Charger: Float-charges up to 18 AH; cabinet fits 7 AH; charger disable switch for larger external batteries.
- Flexible Outputs: Configure all resettable, all non-resettable, or mixed to power peripherals and four-wire detectors.
- Comprehensive Supervision: Power supply, battery, and NACs all supervised; selectable earth-fault detection.
- Compact Cabinet: Locking enclosure with clamp-type terminals up to 12 AWG for simple, robust field wiring.
The FCPS-24S6RB delivers the reliability and precision required for NAC expansion, synchronized notification, and regulated 24 V power distribution in life-safety systems.
