Lifesafety Power FPO150/250-2C82D8PE4M1 Dual-Output Power Supply Enclosure
The FPO150/250-2C82D8PE4M1 is a 400W dual-output power supply housed in a compact E4M1 enclosure (24"H × 20"W × 4.5"D) designed for access control systems, door strike frames, and distributed surveillance infrastructure requiring simultaneous 12V and 24V power rails. The integrated 16-channel Mercury relay provides low-voltage switching for electric locks, alarm devices, and auxiliary control circuits — a common requirement in multi-door security installations where a single power supply must feed both logic circuits and load devices at different voltage requirements.
Overview
Deploy this supply in security cabinets, alarm panels, or network equipment closets where you need reliable dual-rail output without stacking separate supplies. The 400W capacity supports multiple door strikes, wireless access points, sensors, and relay-controlled loads simultaneously. Mercury relay technology ensures low contact resistance and long cycle life for frequent on/off switching typical in badge-reader and buzzer circuits. The E4M1 enclosure is designed for flush or surface mounting in equipment racks and cabinets — standard footprint for legacy Lifesafety Power installations.
Compatibility
Integrates with most access control panels and alarm systems that support external 12V/24V dual-rail power input, including legacy installations using Mercury relay modules. The 16-channel relay bank supports standard door strike wiring patterns (typically 2–4 channels per door). Confirm your panel's input voltage requirements and current draw per channel before integration — total load cannot exceed 400W across both rails.
Installation Notes
Mount the enclosure in a secured equipment cabinet or wall-mounted lockable box to protect the power distribution and relay circuits. Verify AC mains supply is adequate for 400W continuous draw. Use appropriately rated circuit protection on the input side. Relay wiring should follow the panel manufacturer's terminal diagram — Mercury relays are polarity-sensitive and relay contacts are rated for low-voltage DC switching only. Ensure adequate ventilation around the enclosure if mounted in a sealed cabinet; passive convection cooling is typical for this class of supply.
