It supports both standalone and NAC-expander operation modes, and is fully compatible with virtually any UL 864 fire alarm control panel. The unit features a selectable battery charging circuit, synchronization support for appliances from System Sensor, Gentex, and Wheelock, and two fully-isolated trigger inputs. It is commonly used to extend NAC circuits or provide auxiliary 24V power for door holders, smoke detectors, and annunciators. The HPF24S8 also includes built-in supervision and LED diagnostics, enhancing system reliability and serviceability. Key Features: High Output Capacity: Provides 6A (continuous) or up to 8A (NAC expander mode) at 24VDC. Battery Backup: Includes integrated charger for up to 18 AH lead-acid batteries. Flexible Output Configuration: Supports four Class B or four Class A NACs (with ZNAC-4). UL-Compliant Synchronization: Compatible with System Sensor, Wheelock, and Gentex strobes. Standalone or NAC Expander: Works independently or with FACP notification circuits. Resettable/Non-resettable Options: Configurable per output circuit with full supervision. Selectable AC Trouble Delay: Settable to immediate or 8-hour reporting. Isolated Input Control: Two fully-isolated circuits allow separate triggers or permanent enable. Trouble Contact Output: Form-C relay rated at 5A @ 24VDC for remote fault monitoring. Compact Enclosure: Lockable cabinet houses internal charger and supports 7.0 AH battery. The HPF24S8 delivers robust power and flexibility for expanding fire alarm and auxiliary 24VDC power systems while maintaining full supervision and safety compliance.
