It can operate in coordination with main fire alarm panels or as an independent power supply for additional devices. With field-selectable configuration options, the EBPS6A supports a range of signal rates including continuous, 120 SPM, temporal (3-3-3), or direct following of the main panel NAC. The enclosure accommodates up to two 10Ah batteries internally, with external capacity up to 65Ah for access control applications. Designed for flexibility, the EBPS6A can be cascaded, independently controlled, or configured for auxiliary outputs, making it ideal for fire alarm, MNEC, security, and access control systems. Key Features: 6.5A Output Capacity: Provides supervised 24 VDC power for fire alarm and emergency circuits. Four NAC Outputs: Configurable as four Class B or two Class A supervised circuits. Per-Circuit Rating: Each NAC delivers up to 3.0 A at 24 VDC nominal. Auxiliary Power Options: NAC 3 and 4 can be configured as auxiliary outputs. Battery Charging Support: Charges and supervises internal or external batteries (up to 65Ah external). Configurable Signal Rates: Supports continuous, 120 SPM, 3-3-3 temporal, or following main panel NAC. Overcurrent Protection: Self-restoring circuitry ensures safe and reliable operation. Diagnostic LEDs: Seven onboard indicators for NACs, AC, battery, and ground fault monitoring. Flexible Mounting: Lockable steel cabinet with space for additional interface modules. UL 864 9th Edition Listed: Certified for fire alarm, life safety, and MNEC applications. The EBPS6A delivers the reliability and supervision required for expanding notification and auxiliary power in Edwards fire alarm systems.
