Lifesafety Power FPO250/250-5D8P3M8NLCE12M/P24-A Mercury ProWire Power Supply
Overview
The FPO250/250-5D8P3M8NLCE12M/P24-A is a 500W dual-voltage power distribution system designed for access control and security infrastructure. It delivers 24 managed lock outputs and 40 auxiliary power outputs, making it the right choice for multi-door access control deployments where you need centralized, managed power to locks, readers, and ancillary devices without individual UPS modules at each door. Input is 120 VAC. The managed outputs let you control power sequencing and load-shedding across the system — essential in brownout conditions or when you need to prioritize critical doors while deprioritizing less critical zones.
Compatibility
The Mercury ProWire platform integrates with access control systems using standard supervised power distribution architectures. It is compatible with systems that require managed 24 VDC outputs for electric strikes, magnetic locks, and badge readers. Verify compatibility with your specific VMS or access control panel by cross-referencing your panel's power-input specification and the number of door/auxiliary circuits required. The managed lock outputs are designed to work with standard access control wiring schemes where power sequencing or load management is handled by the control panel or a separate management module.
Installation Notes
Input voltage is 120 VAC — confirm your facility power supply matches before installation. The 24 managed lock outputs and 40 auxiliary outputs distribute the 500W load across multiple circuits; do not exceed the rated output current per circuit, typically 1–2A per managed lock line depending on configuration. Install in a dry, temperature-controlled enclosure; verify local electrical codes and bonding requirements before commissioning. Wire management and labeling of output circuits is critical for maintenance access — use cable ties and label the terminal block clearly for each door or zone.
