Lifesafety Power FPO75-B100C4D8E1M 75W Power Supply with Relay Control

Overview

The FPO75-B100C4D8E1M is a 75W power distribution module designed for access control, door lock, and auxiliary device management in security installations. It delivers either 6A at 12VDC or 3A at 24VDC from the primary supply, with a secondary 12V output rated at 4A. The adjustable 5-18V output (4A maximum) accommodates variable voltage equipment without requiring separate regulators, reducing wiring complexity in retrofit deployments where legacy devices operate at non-standard voltages.

Output Architecture

The module includes 4 relay-controlled lock outputs (each fused at 3A) selectable per output for failsafe, failsecure, or FAI (fire alarm input) mode—critical for door locking strategy in life-safety scenarios. Eight additional DC auxiliary outputs (also 3A fused each) support Bus1 or Bus2 control, enabling simultaneous management of multiple lock controllers, request-to-exit devices, or auxiliary loads from a single power supply unit.

Physical Specifications

The E1 enclosure measures 14H × 12W × 4.5D inches with a Mercury back plate, designed for wall or DIN-rail mounting in equipment rooms or cabinets. Compact form factor minimizes footprint in existing installations without sacrificing fused output capacity.

Installation Considerations

Each relay and auxiliary output carries independent 3A fusing, protecting against short-circuit damage to downstream devices. Failsafe/failsecure selectability per output allows mixed-mode locking on multi-door access control systems without additional relays or controllers. Battery backup capability should be evaluated against facility power redundancy requirements during system design.
