Lifesafety Power FPO75-B100C8D8E4M 75W Power Supply Module
Overview
The FPO75-B100C8D8E4M is a 75W Class 2 power-limited supply designed to feed access control and life safety systems that require discrete relay and DC auxiliary outputs. It delivers 12V at 6A or 24V at 3A from the primary winding, with an adjustable secondary output (5–18V @ 4A max) for flexible endpoint power needs. The eight fused relay lock control outputs (3A per output, selectable FAI/failsafe/failsecure) simplify door strike and electromechanical lock wiring by eliminating external relay banks. Eight additional DC auxiliary outputs (3A per output, selectable Bus1/Bus2) support distributed control logic without secondary power distribution. This topology reduces installation complexity on warehouse automation, building access, and emergency egress systems where multiple locks or solenoids must coordinate under power-loss conditions.
Compatibility
The FPO75-B100C8D8E4M integrates into Lifesafety Power panel ecosystems and third-party access control platforms that accept 12VDC or 24VDC distributed power with relay supervision. It supports systems requiring independent Bus1/Bus2 auxiliary circuits for zone isolation or redundant control paths. Verify your panel's input voltage (typically 24VAC or 12VDC) and relay voltage rating before ordering; output voltage selectability does not change primary winding compatibility.
Installation Notes
The E4 enclosure (24H × 20W × 4.5D inches) mounts vertically on a DIN rail or wall. Each relay and auxiliary output is fused at 3A; confirm load current per device (door strike, magnetic lock, solenoid) does not exceed output capacity. The Mercury back plate provides mechanical strain relief and grounding. Relay output contacts support dry-contact loads only; do not apply voltage directly to relay terminals. Configure failsafe/failsecure and Bus assignment in the field using the selectable terminal strips—no firmware programming required.
