Lifesafety Power FPO75-B100C4D8PE4M/T4-C 75W Dual-Output Access Control Power Supply

Overview

The FPO75-B100C4D8PE4M/T4-C is a 75W regulated power supply designed to feed 4-door access control systems with independent 12VDC and 24VDC outputs. The unit delivers 2A at 12V and 2A at 24V simultaneously, allowing mixed-voltage field equipment (mag locks, request-to-exit buttons, door sensors, auxiliary devices) to operate from a single enclosure. This topology eliminates the need for separate power conditioning per voltage rail — critical in warehouse automation, building access, and multi-tenant security deployments where space and thermal load are constraints.

Compatibility

The FPO75-B100C4D8PE4M/T4-C integrates with access control systems requiring dual regulated outputs and supervision circuits. The unit includes 4 relay outputs (typically wired to door-strike or badge-reader supervisory circuits) and 8 auxiliary outputs for alarm signaling or status indication. Verify your access control panel's input voltage and current requirements before specifying — most 4-door systems expect 2A minimum per rail under full load.

Installation Notes

Wire all MR52 tie wraps as noted in the wiring diagram. Route 12V and 24V return lines separately to prevent ground-loop noise that degrades door sensor reliability. Mount in a UPS-backed or conditioned rack to ensure access control continuity during power transients. Verify circuit breaker sizing upstream: at 75W full load and dual-output topology, a 10A breaker is typical, but confirm with your site electrical plan.
