Lifesafety Power E4H1-BOXED Honeywell Boxed Power System

Overview

The E4H1-BOXED is a UL-listed power distribution enclosure that pairs Lifesafety Power FlexPower modules with Honeywell access control hardware in a single compact chassis. Deploy this when you need to combine door control power, camera distribution, and credential readers in one location—typically access control rooms, server closets, or consolidation points where wiring runs converge. The boxed system approach eliminates the need for separate power shelves and control panels, reducing overall footprint and simplifying single-point installation.

Compatibility

The E4H1-BOXED integrates with Honeywell access control systems and legacy card readers. It accepts standard 24VDC inputs and provides outputs suitable for electromagnetic locks, request-to-exit sensors, and door strike hardware. Verify your specific Honeywell controller model and reader series against the system's output amperage and relay specifications before ordering—different reader types and strike mechanisms draw different currents, and undersizing at the power stage is a common integration mistake.

Installation Notes

Mount the E4H1-BOXED in a secure, climate-controlled enclosure or rack. Input supply must be 24VDC from a reliable UPS-backed source; do not feed it from an unreliable or shared building circuit. Ensure main breaker and branch protection are sized to the total load of all connected readers, locks, and auxiliary devices. Bond all grounds to the building grounding system per NEC and local code. Verify environmental temperature range matches your location before deployment—thermal stress on power modules is cumulative and reduces relay lifespan.
