Lifesafety Power FPV4-R8E1 4A 8-Output Access Control Power Supply
Overview
The FPV4-R8E1 is a dedicated access control power supply rated for 4A total output distributed across 8 independent relay outputs. This configuration allows you to power and supervise up to eight 12VDC magnetic locks, electric strikes, or similar solenoid loads from a single enclosure—reducing wiring complexity and centralizing power management in door control and multi-lock access installations.
Specifications & Deployment Benefit
The 4A rating at 12VDC provides sufficient capacity for typical electromagnetic locks drawing 400–600mA each, with headroom for supervised wiring and fault detection. Eight independent outputs mean each lock can be controlled, monitored, and fused individually—critical for systems requiring granular door-level diagnostics and failsafe operation. This architecture scales efficiently across warehouse access points, data center secure rooms, and commercial entry control systems where multiple doors must be powered and status-reported independently.
Compatibility
The FPV4-R8E1 integrates with Lifesafety Power access control panel lines and works with any third-party 12VDC access control system that accepts relay supervision outputs. Verify your panel's power and supervision input specifications against the unit's datasheet before deployment.
Installation Notes
Confirm input voltage requirements and battery backup availability from the product documentation. Validate each output load does not exceed the 4A total budget when all locks operate simultaneously. Size conduit and wire gauge per NEC/local electrical code for the installed amperage.
