This UL 864 9th Edition listed unit can be cascaded or operated independently, making it suitable for large-scale installations. It includes onboard diagnostics with LED indicators for wiring and internal faults, as well as self-restoring overcurrent protection for dependable performance. The enclosure accommodates two 10Ah batteries internally, while larger capacities up to 65Ah are supported in external enclosures for access-control-only applications. Key Features: High-Capacity Output: Provides 10 A total current across four Class B or two Class A NACs. Per-Circuit Rating: Delivers up to 3.0 A per NAC output at 24 VDC nominal. Filtered & Regulated Power: Ensures stable 24 VDC output for life safety and auxiliary devices. Battery Charging: Charges and supervises internal or external batteries up to 65 Ah (external enclosure required). Diagnostic LEDs: Onboard indicators for fault detection and troubleshooting. Overcurrent Protection: Self-restoring circuitry safeguards connected devices. Synchronization Support: Compatible with Genesis and Enhanced Integrity appliance synchronization. Flexible Operation: NACs can be cascaded or controlled independently for system expansion. Dual Input Circuits: Allows grouping of NAC outputs into one or two activation zones. Durable Enclosure: Lockable red steel cabinet with space for two 10Ah batteries. Field Configurable: Simple jumper and wiring options for Class A/B NAC setup. The EBPS10A delivers the reliability and performance required for expanding NAC and auxiliary power in Edwards fire alarm and emergency communication systems.
