Lifesafety Power FPO250-B1002C8D8E4M1 Dual-Bus Fused Power Supply
Overview
The FPO250-B1002C8D8E4M1 is a 250W power supply designed for access control and security infrastructure requiring isolated DC distribution across multiple circuits. It delivers 20A at 12VDC or 10A at 24VDC, eliminating single-point power failures by segregating loads across two independent buses. Each bus supplies eight fused 3A DC auxiliary outputs—ideal for powering IP cameras, door readers, locks, and sensors without voltage sag. The eight relay lock control outputs add supervised egress switching for failsafe, failsecure, and LABEL-mode door hardware, each independently configurable per bus assignment.
Compatibility
The FPO250-B1002C8D8E4M1 integrates into Lifesafety Power access control ecosystems and mixed security deployments where distributed DC power and relay supervision are required. Dual-bus architecture allows load balancing between two separate circuits—Bus1 and Bus2—each output individually selectable. Relay outputs support C4/C8 jumper configuration for failsafe/failsecure logic. Compatible with standard 12/24VDC door hardware, magnetic locks, and access control readers operating within 3A per-output limits.
Installation Notes
Each of the eight DC auxiliary outputs is fused at 3A—confirm total load per bus does not exceed 20A (12V) or 10A (24V) to avoid nuisance shutdown. Relay control outputs are independently fused at 3A per output and selectable for FAI (Fire Alarm Interface), failsafe, or failsecure operation via C4/C8 jumper configuration. Wiring must follow local electrical code for access control power circuits; consult the FPO75-250 ComboManual and C4/C8 Quick Guide for bus assignment and relay logic diagrams. Aux output distribution reduces voltage drop on long runs compared to single-supply designs—measure drop at the load if wire run exceeds 50 feet.
