Lifesafety Power FPO250/250-3C85D8PE12M/P24-C Access Control Power Supply

Overview

The FPO250/250-3C85D8PE12M/P24-C is a 250W dual-voltage access control power supply rated for 20A at 12V or 10A at 24V output — built to drive multiple relay-controlled electric strikes, magnetic locks, and auxiliary loads in mid-sized access control systems. This unit is designed for FAI (Failsafe/Failsecure Addressing Interface) environments where selectable lock behavior (failsafe vs. failsecure per door) is a core requirement. It fits wall-mounted or rack-mounted installation in security rooms, electrical closets, or equipment racks serving office buildings, data centers, and facility access networks.

Compatibility

Direct FAI-compatible system integration. The FPO250/250-3C85D8PE12M/P24-C works with access control panels and controllers that support FAI relay control protocols and auxiliary power distribution. Eight selectable relay lock control outputs (3A fused per output) enable independent failsafe/failsecure assignment — meaning you can set one door to fail open on power loss and another to fail locked, all from the same supply. Eight 2.5A DC auxiliary outputs are selectable for Bus1 or Bus2, supporting distributed card readers, request-to-exit sensors, and status indicators across your access control layout.

Installation Notes

Dual voltage output (12V or 24V) reduces site inventory — select output voltage to match your lock and reader hardware before installation. Eight 3A fused relay outputs mean each output is independently protected; a short on one lock circuit won't cascade to others. Requires 120VAC or 240VAC input (verify your unit's input configuration); verify main panel breaker capacity before drawing 250W sustained load. Relay coil voltage and auxiliary load amperage must not exceed specified per-output limits — exceeding 3A on relay outputs or 2.5A on auxiliary outputs will trip fuses.
