Lifesafety Power E4M1-BOXED Access Control Enclosure

Overview

The E4M1-BOXED is a painted steel enclosure built to mount Lifesafety Power Mercury and LNL access control boards in compact door control installations. It houses up to 5 Mercury or LNL boards when paired with an FPO power supply, or up to 6 boards if you're supplying power externally. The 20W rating refers to the power delivery capacity — enough for small-to-medium door control clusters without requiring a separate cabinet.

The enclosure measures 20 inches wide × 24 inches high × 4.5 inches deep (compact mounting footprint for wall or panel installation). It ships with a keyed lock, tamper switch, and pre-drilled backplate that accepts Mercury/LNL boards. Door studs allow mounting of up to 6 additional boards if your panel layout requires it.

Compatibility

Designed for Lifesafety Power Mercury and LNL board families. The backplate mounting accepts boards via the standard FPO power supply connector. If you're integrating a single-door or two-door control point into a larger access system, verify your board models are Mercury or LNL revision — older Gemini or custom boards may require adapter hardware. Check your board's connector pinout against Lifesafety Power documentation before ordering.

Installation Notes

Mount the enclosure to a wall or DIN rail using the included hardware. Position it away from direct sunlight and moisture; it is not rated for outdoor or wet environments. The tamper switch reports to your access control system when the door is opened — wire it into your panel's alarm input. Ensure adequate ventilation around the unit if ambient temperature exceeds 60°C; the 20W rating assumes passive cooling in standard commercial spaces (typically 15–25°C).
