Lifesafety Power FPO75-C4E2M 75W Power Supply Board

Overview

The Lifesafety Power FPO75-C4E2M is a 75W power supply board designed for access control and lock management in small-to-medium commercial installations. It delivers either 6A at 12V or 3A at 24V depending on your system voltage, eliminating the need to source separate power conditioning for door locks, readers, and control relays. The four relay outputs are individually fused at 3A each—meaning you can independently control up to four separate lock or electromagnetic device circuits without a single failure cascading across your access points.

Compatibility

The FPO75-C4E2M integrates with standard access control panels and legacy door lock systems that require 12V or 24V auxiliary power. It pairs with conventional electric strike locks, magnetic locks (maglocks), and relay-driven door operators common in commercial and institutional deployments. Verify your panel's power requirements before specifying—this board is a power distribution point, not a standalone access controller.

Installation Notes

Mount the board in a climate-controlled cabinet or electrical enclosure—no outdoor exposure. Wire 12V or 24V input from your main power source to the board's input terminals, then run individual 18 AWG or heavier conductors from each relay output to your locks and readers. The 3A per-output fuse protection prevents a shorted lock or reader from taking down the entire system. Observe proper terminal torque during installation to avoid intermittent connections under load.
