Lifesafety Power FPO75-B100C4D8E2M Dual-Voltage Access Control Power Supply
Overview
The FPO75-B100C4D8E2M is a 75W enclosure-mounted power supply designed for Mercury access control systems and legacy electronic locking environments. It delivers simultaneous 12V/2A and 24V/2A outputs — a real requirement in mixed-voltage door-control deployments where some readers run 12V logic and lock solenoids demand 24V. The enclosure dimensions (20H × 16W × 4.5D inches) fit standard cabinet rails and wall-mount brackets, keeping wiring runs short and fused distribution local to the lock circuits.
Compatibility
Purpose-built for Lifesafety Power Mercury system installations. The supply's 4 dedicated fused lock outputs and 8 fused auxiliary outputs support multi-door configurations where each door lock circuit needs independent overcurrent protection — a safety requirement in commercial access control. If you're retrofitting or expanding an existing Mercury panel or integrating standalone electronic locks into a cabinet, verify your panel's connector type and voltage rail labeling before ordering to avoid cross-wiring.
Installation Notes
Mount the enclosure to a DIN rail or wall using the pre-drilled holes. Fused outputs prevent downstream damage if a door strike coil shorts or a solenoid fails. Total output capacity is 75W across both voltage rails — do not exceed this limit when calculating lock solenoid draws and reader power together. Ensure all AC mains connections are made by a qualified electrician and properly grounded per local electrical code. No PoE or network connectivity on this unit — it is a standalone DC power distribution device.
