Lifesafety Power FPO75-2D8E4M 250W Power Supply
Overview
The FPO75-2D8E4M is a 250W auxiliary power supply designed for access control and door integration in commercial security systems. It provides dual output options—20A at 12V or 10A at 24V—with class 2 power-limited outputs capped at 2.5A per channel. Each of the four outputs is independently selectable for Bus1 or Bus2 operation, allowing flexible configuration across multiple control loops without cross-chaining. The E12 enclosure (48H × 36W × 8D inches) with Mercury backplate accommodates standard 24-door configurations and mounts into standard electrical cabinetry.
Compatibility
The FPO75-2D8E4M integrates with Lifesafety Power access control systems and third-party controllers that require dual-bus auxiliary power delivery. Bus1/Bus2 selection per output supports redundant or multi-zone door control architectures. Confirm your controller's voltage and current requirements (12V or 24V, under 2.5A per output channel) before deployment.
Installation Notes
Class 2 power-limited design simplifies low-voltage wiring in occupied spaces and reduces conduit sizing versus line-voltage installations. Each output is independently selectable via internal configuration; plan your Bus1/Bus2 topology before commissioning to avoid reconfiguration during live operation. The E12 form factor requires standard electrical cabinet space and AC mains input; verify available breaker capacity on your site panel before ordering. Mercury backplate mounting is standard; no additional hardware needed for typical 24-door cabinet installation.
