Lifesafety Power FPO75-B100C4PD8PE4M Access Control Power Supply Enclosure
Overview
The FPO75-B100C4PD8PE4M is a 75W access control power supply designed for Mercury-based lock and door control systems. It provides dual regulated outputs—2A at 12V and 2A at 24V—to support four Class 2 lock outputs plus eight auxiliary Class 2 outputs. The E4M enclosure measures 14 inches (H) × 12 inches (W) × 4.5 inches (D), fitting standard wall-mount or rack installations in electrical closets, server rooms, or entry control rooms where you need compact, code-compliant power distribution for access control devices.
Compatibility
This supply is engineered for Lifesafety Power Mercury system lock control architectures. Verify compatibility with your specific Mercury door controller model and lock configuration before ordering. The dual-voltage design (12V and 24V simultaneous) accommodates mixed lock and solenoid voltages in a single enclosure, reducing installation complexity on multi-voltage access control floors. The four dedicated lock-class outputs and eight auxiliary outputs provide flexibility for smaller multi-door systems without over-provisioning.
Installation Notes
The E4M enclosure is designed for wall or panel mounting. Confirm that your electrical panel can support the 75W draw during worst-case lock-activation scenarios (all four locks energized simultaneously plus auxiliary loads). Class 2 wiring (24V max, low-energy) does not require conduit in most jurisdictions, but verify local electrical code. Ensure adequate ventilation around the enclosure—do not block vents or stack equipment directly above or below. Use appropriate gauge wire for 12V and 24V distribution runs based on distance to locks; longer runs may require oversizing to minimize voltage drop at lock coils.
