Fire Alarm Power Supplies and Communicators


The HPF24S8C is a compact, cost-effective, 8-amp remote power supply with a battery charger built in. It may be connected to any 12- or 24-volt Fire Alarm Control Panel (FACP) or may stand alone. Primary applications include Notification Appliance (bell) Circuit (NAC) expansion (to support ADA requirements and NAC synchronization) or auxiliary power to support 24-volt system accessories.

The supply provides regulated and filtered 24 VDC power to four Notification Appliance Circuits configured as either four Class B (Style Y) or Class A (Style A, with ZNAC-4 option module). Alternately, the four outputs may be configured as all non-resettable or all resettable or two non-resettable and two resettable. It also contains a battery charger capable of charging up to 18 Amp Hour batteries.
