Lifesafety Power FPO150/250-2C83D8PE8M1/P16-B 150W/250W Dual-Output Power Supply with 16 Relay Lock Outputs
Overview
The FPO150/250-2C83D8PE8M1/P16-B is a dual-output power supply designed for access control and security infrastructure deployments where multiple door locks, magnetic locks, and auxiliary devices require independent, supervised power distribution. The unit supports either 150W at 12A/12V or 6A/24V, or 250W at 20A/12V or 10A/24V operation — selectable to match your control panel voltage requirements. Sixteen relay-controlled outputs (3A fused per output) provide failsafe, failsecure, or FAI (Fire Alarm Interface) switching modes per output, eliminating the need for external relay modules in medium-density access control cabinets.
Compatibility
This unit integrates with Lifesafety Power control panels and third-party access control systems that require supervised, relay-switched 12VDC or 24VDC auxiliary power. The Mercury MR52 / EP2500 board compatibility and E8 enclosure form factor (36H × 30W × 4.5D inches) align with standard 19-inch rack and cabinet mounting. Two independent 24VDC class 2 auxiliary outputs (2.5A per output, Bus1/Bus2 selectable) support sensor networks and auxiliary signaling without consuming relay capacity.
Installation Notes
Each relay output is independently fused at 3A, protecting individual circuits from overcurrent without affecting remaining outputs — critical for isolating lock failures in multi-door deployments. Failsafe/failsecure selection per output allows mixed lock behavior in the same cabinet (e.g., entry doors failsecure, emergency exits failsafe) without additional hardware. Mount in a climate-controlled equipment enclosure to maintain relay contact reliability; operating temperature and humidity specifications should be confirmed with your installer if the cabinet lacks thermal management.
