Lifesafety Power FPO75-B100C8D8E4M1 75W Power Supply with Multi-Output Control Module

Overview

The FPO75-B100C8D8E4M1 is a 75W industrial power supply engineered for access control and security integration environments where dual-voltage output, relay switching, and supervised auxiliary circuits are mandatory. This module delivers 6A at 12VDC or 3A at 24VDC primary output, with adjustable 5–18V secondary @ 4A max — enabling heterogeneous powered endpoint architectures on a single supply rail. The 8 Class 2 power-limited relay lock control outputs (fused independently at 3A per output) support per-output failsafe/failsecure/FAI (Fail as Is) selection, critical for networked door and gate controllers. Eight additional DC auxiliary outputs (also 3A fused, selectable per Bus1/Bus2) provide supervised monitoring and distribution to subordinate access devices, reducing point-of-failure risk in larger integration schemes.

Compatibility & Integration

The module fits E4 enclosure geometry (24H × 20W × 4.5D inches) with Mercury back plate and door-mount kit included, integrating into standard electrical cabinet and wall-mount scenarios. Output voltage selection and per-output control mode configuration support mixed-voltage installations where power infrastructure must serve both legacy 12VDC and modern 24VDC access readers, magnetic locks, and request-to-exit devices. Relay and auxiliary output selectability (failsafe vs. failsecure per output) accommodates varying security postures across multiple access points on a single supply — typical in warehouse automation, facility perimeter control, and multi-zone entry environments.

Installation Considerations

Each relay and auxiliary output carries independent 3A fusing, limiting fault propagation if a downstream load shorts or draws excess current. Secondary adjustable output (5–18V @ 4A) supports auxiliary sensors, status indicators, and low-power control circuits without requiring a separate power tap. Configurable output destination (Bus1/Bus2) enables logical segmentation of loads, reducing interdependency when integrated with networked access control panels or supervisory switching systems.
