Lifesafety Power FPO250/250/250-3D8P5M8PNLCE12M/P24-B Mercury Pro Power Supply
Overview
The Lifesafety Power FPO250/250/250-3D8P5M8PNLCE12M/P24-B Mercury Pro is a 750W dual voltage access control power supply designed to support mid-to-large security installations requiring distributed power to door locks, access readers, and auxiliary devices. Operating at 120 VAC input, this unit distributes power across 40 managed lock outputs and 24 auxiliary outputs—the configuration needed when a single centralized power shelf must feed access control panels, electric locks, and remote readers across multiple zones without requiring separate power runs to each location. This topology cuts installation labor and simplifies monitoring of lock circuit health.
Compatibility
The FPO250 Mercury Pro integrates with access control systems using standard 24 VDC lock circuits and auxiliary power busses. Verify compatibility with your access control panel's power distribution architecture—specifically the connector types and current-per-circuit specifications for managed outputs. The unit's 40 dedicated lock outputs and 24 auxiliary channels support typical enterprise door control installations where locks and readers are distributed across building floors or zones. Consult your panel documentation to confirm the unit's output configuration matches your system's power pin layout and voltage isolation requirements.
Installation Notes
Input: 120 VAC single-phase. Verify local mains capacity before installation—750W demand requires a dedicated 15A circuit minimum. Outputs are managed and individually monitored, allowing the control panel to sense lock circuit shorts or disconnects per output. Wire all AC input connections to code and include appropriate over-current protection upstream of this unit. Ensure adequate ventilation space around the enclosure to prevent thermal stress during sustained multi-lock operation (e.g., badge-reader traffic during shift changes or emergency unlock events).
