Lifesafety Power FPO75/75-3D8PE4M1 Mercury Unified Power System
Overview
The FPO75/75-3D8PE4M1 is a 150W unified power supply designed to centralize and distribute power to access control panels, card readers, electronic locks, and ancillary security devices across distributed installations. Dual voltage input (24 VDC / 12 VDC switchable output) means a single unit can support mixed-voltage device ecosystems — common in retrofit or multi-vendor integrations where replacing legacy hardware isn't practical. The 24 auxiliary outputs provide daisy-chain or radial distribution to field devices, reducing the number of separate power supplies you need to manage and mount in cabinets or weatherized enclosures.
Compatibility
Verify compatibility with your specific Mercury system controller or access control panel before integration. The FPO75/75-3D8PE4M1 works within Lifesafety Power's Mercury ecosystem and is designed to power auxiliary devices (lock solenoids, request-to-exit buttons, door sensors, alarm outputs) that draw under 150W combined. Check your panel's power requirements and auxiliary load budget in your system design documents — exceeding the 150W rating or connecting incompatible voltage loads will damage the supply and potentially the connected devices.
Installation Notes
Mount in a secure, climate-controlled location (cabinet, closet, utility room) away from moisture and direct sunlight. Ensure adequate ventilation around the unit to prevent thermal stress. Use appropriately rated circuit breaker protection and backup battery provision if your system requires power continuity during mains failure. Verify mains voltage matches the supply's input specification, and confirm all auxiliary wiring is properly labeled and secured to avoid accidental miswiring during maintenance or troubleshooting.
