Lifesafety Power E8M2-BOXED 16-Door Wall-Mount Power Distribution
Overview
The Lifesafety Power E8M2-BOXED is a wall-mounted power distribution enclosure designed to centralize and protect 16 access control door circuits in commercial security installations. This Mercury-grade cabinet measures 36 inches high by 30 inches wide and accepts 120VAC input — a standard facility voltage that eliminates the need for specialized step-down transformers in most environments. The boxed form factor and pre-drilled wall-mount design simplify installation in retrofit and new-build scenarios where space or aesthetic constraints rule out floor-standing cabinets.
The E8M2-BOXED (often searched as E8M2 BOXED) is purpose-built for integrators managing multi-door access control systems where power distribution, supervision, and wiring concentration matter. Its 16 dedicated outputs eliminate daisy-chaining and reduce single-point failure risk — each door circuit gets its own protected branch.
Key Features
- 16 Dedicated Door Outputs: One supervised power output per door lock or reader pair. This isolation prevents one faulty circuit from dragging down the entire system, and simplifies troubleshooting when a door controller signals a fault.
- 120VAC Input: Accepts standard building AC power without requiring a separate transformer. Most facilities already have 120VAC circuits available near security equipment closets or panel rooms, shortening rough-in runs and lowering material cost.
- Wall-Mount Enclosure: The 36"H x 30"W footprint mounts directly to drywall or paneling, preserving floor space in closets and utility rooms where NVRs, switches, and other equipment compete for real estate. This is especially valuable in small server rooms or retrofit installations where cabinet depth is limited.
- Mercury Security-Grade Cabinet: The enclosure construction and locking mechanism meet Mercury security cabinet standards, protecting internal terminals and wiring from casual tampering or accidental contact — a regulatory requirement in many commercial access control deployments.
- Supervision Capability: The E8M2-BOXED supports circuit supervision (status reporting on each output), allowing the access control panel to detect open circuits, short conditions, or disconnected devices in real time. This feeds directly into audit logs and alerts.
- Boxed Configuration: Ships complete and ready to mount; no assembly required beyond wall installation and terminal wiring. Reduces pre-deployment labor and the risk of misconfigured modules or missing internal jumpers.
Integration & Compatibility
The E8M2-BOXED connects downstream from any standard 16-output access control panel or power distribution controller that outputs 120VAC supervision signals. It is commonly paired with panels from the major access control platforms — Salto, Honeywell, Genetec, Axis — provided the panel supplies the requisite supervision voltage. Verify your access control architecture requires 16 discrete door circuits before committing; smaller deployments may suit a modular 4- or 8-door variant in the same family.
The wall-mount form factor assumes wiring will drop from above or route through conduit from a nearby panel room. Ensure your facility's cable management policy permits visible or in-wall runs to the enclosure location. Some integrators mount the E8M2-BOXED in a dedicated equipment closet behind the access control server; others install it near a common area entry or stairwell if supervision cabling is already in place.
Frequently Asked Questions
Q: Does the E8M2-BOXED include battery backup?
A: No. The E8M2-BOXED is a power distribution enclosure; it does not house an internal battery or UPS. Backup power must be supplied upstream at the main access control panel or via a separate UPS serving the facility's security circuits. If you require hold-up power for door locks during a mains failure, provision a battery-backed supply at the panel level.
Q: Can I wall-mount the E8M2-BOXED in an outdoor location?
A: The enclosure is not sealed for outdoor exposure. Install it indoors in a climate-controlled closet, utility room, or equipment cabinet. Outdoor installations risk moisture ingress and corrosion of terminals.
Q: What is the maximum current draw per door output on the E8M2-BOXED?
A: Verify with your access control integrator or the panel manufacturer, as output current rating depends on the supervision and supply architecture of the controlling panel. Do not assume all 16 outputs can source maximum current simultaneously; load distribution across doors is typically conservative (e.g., 1–2 A per output) to avoid thermal stress.
Q: Is the E8M2-BOXED compatible with my Milestone or Genetec system?
A: The E8M2-BOXED is a hardware distribution appliance, not a software plugin. It integrates with any access control panel that outputs 120VAC supervision. Genetec and Milestone systems do not directly control door power distribution — your access control panel does. Confirm that your access control panel supports the E8M2-BOXED form factor and supervision protocol.
Q: What are the mounting hardware requirements?
A: The enclosure includes pre-drilled holes for wall mounting. Standard lag bolts or toggle anchors into drywall are typical; for masonry or concrete, use expanding anchors rated for the cabinet weight. Ensure the wall surface can support the fully loaded enclosure without flexing.
The E8M2-BOXED is a straightforward, no-nonsense choice when your access control deployment calls for 16 isolated door circuits and you need to keep the enclosure footprint tight. The 120VAC input is the key specification here — it eliminates the step-down transformer that would otherwise consume cabinet space and add a single point of failure between the main panel and your door power distribution.
Technical Highlights:
- 16 Dedicated Supervised Outputs: Each door lock or reader circuit gets its own branch with supervision reporting back to the access control panel. This architecture catches open circuits and short faults in milliseconds, which means your security audit logs stay clean and your NOC doesn't get flooded with cascading alerts from a single bad wire.
- 120VAC Input Simplifies Infrastructure: Most facilities have 120VAC readily available in equipment rooms or closets. You avoid sourcing a transformer, running additional power runs from the main panel, or negotiating space constraints in an already-packed electrical closet. Shorter wiring runs = lower voltage drop and faster commissioning.
- Mercury Cabinet Standard: The enclosure construction and latching mechanism meet Mercury security specifications. This matters if your facility or customer has compliance audits; it's also insurance against tampering or accidental contact that could short a door circuit.
Deployment Considerations:
- The E8M2-BOXED is strictly indoor, climate-controlled duty. If you're mounting it in a vestibule or any space subject to moisture swings, condensation, or temperature extremes, plan for a sealed enclosure or conditioned room instead.
- Supervision cabling must run from your access control panel to the E8M2-BOXED. This is not a plug-and-play device — rough-in planning and careful termination are mandatory. If your site has no existing supervision cabling, budget labor and conduit for the retrofit.
- Do not overload the outputs. The 16-door architecture assumes typical lock and reader power draw (1–2 A per circuit). If you have high-draw credentials readers, mag locks, or additional accessory circuits, validate against the panel's output specifications or you'll trip the supply limits.
The E8M2-BOXED is the right call for mid-scale access control retrofits where 16 doors is the target count, space is a constraint, and your facility's electrical infrastructure is already 120VAC-rich. It's not the device to force into an 8-door deployment or to shoehorn into an outdoor cabling run — choose the correct door count and environment first, then specify this enclosure with confidence.
