Lifesafety Power FPO75-B100C8D8PE4M 75W Power Supply with Relay & Auxiliary Outputs
Overview
The FPO75-B100C8D8PE4M is a 75W dual-output power supply engineered for access control and perimeter security integration where relay-driven lock control and auxiliary equipment supervision are required. The unit delivers 6A at 12VDC or 3A at 24VDC primary output, plus a secondary adjustable rail (5–18V, 4A max) for powering low-current ancillary loads. This architecture eliminates the need for separate power modules in mixed-voltage deployments—a practical cost and space advantage in retrofit or modular installations.
Compatibility
The FPO75-B100C8D8PE4M integrates with legacy and modern access control systems, electronic lock arrays, and door position sensors. The 8 relay lock control outputs are individually programmable for failsafe, failsecure, or FAI (fire alarm interface) operation, enabling safe fallback behavior during power loss or system fault. The 8 separate class 2 auxiliary DC outputs (2.5A per output, bus-selectable) power auxiliary devices such as request-to-exit buttons, exit delay sirens, or integration with power delivery infrastructure in larger multi-door systems. Each relay output is independently fused at 3A for fault isolation.
Installation Notes
The E4 enclosure (24H × 20W × 4.5D inches) ships with a Mercury back plate, supporting DIN-rail mounting in standard electrical cabinets or wall-mount installations. Dual output voltage selectability (12V/24V primary) requires jumper or terminal configuration at commissioning—verify the datasheet before field wiring. Relay and auxiliary output assignments must be mapped during system programming to ensure failsafe defaults match site safety requirements (life safety code compliance recommended for door control applications).
