Lifesafety Power FPO150-E4M1 Mercury Backplate Door Mount Kit
Overview
The FPO150-E4M1 is a 150W power supply enclosure assembly combining the E4M1 cabinet with a Mercury backplate and complete door-mount hardware. This is the mechanical and electrical backbone for distributed surveillance and access control installations where field-mounted 12V or 24V power distribution is required. The 150W capacity handles multi-camera or multi-door control circuits in retail, commercial, or industrial settings without needing a centralized UPS room.
Compatibility
The FPO150-E4M1 integrates with Mercury-series control systems and Lifesafety Power cabinet ecosystems. The E4M1 enclosure frame and backplate architecture is designed for din-rail mounted modules and 12A/12V or 6A/24V auxiliary outputs. Verify your existing Mercury control board revision and backplate specification before ordering — backplate variants drive compatibility with specific breaker configurations and relay modules. The door mount kit supports standard wall and electrical box installations in non-hazardous environments.
Installation Notes
The door mount hardware requires standard electrical box preparation and wall studs or concrete anchors rated for the enclosure weight (verify net weight from Lifesafety Power documentation). Mounting bolts should be torqued to manufacturer specifications — loose enclosure fasteners compromise earth ground integrity and introduce vibration noise in low-voltage circuits. Ensure adequate airflow around the enclosure; passive convection cooling assumes 2–3 inches of clearance on top and sides. All wiring (AC input, 12V/24V outputs, and control circuits) must comply with local electrical code and NEC Article 725 (Class 2/Class 3 remote-control circuits). Use appropriate gauge copper conductors for the 12A or 6A load — undersized wire will create voltage drop and nuisance relay dropout, especially on long runs to remote cameras or door strikes.
