Lifesafety Power E8M-BOXED MCLASS Multi-Purpose Enclosure
The Lifesafety Power E8M-BOXED is a modular access-control enclosure designed for integrators who need to combine power management and access-panel hardware in a single, field-serviceable cabinet. Built to house FlexPower power boards alongside Mercury Security access panels, the E8M scales from single-door to 12-door configurations with dual-voltage output distribution. The removable backplate allows shop-side pre-configuration and wiring before site deployment, eliminating on-site panel assembly delays and reducing labor hours on complex multi-door installations.
Key Features
- 12-Door Capacity with Dual Voltage: Supports up to 12 doors across 12V and 24V distribution rails. Single enclosure eliminates the need for secondary power panels on mid-size access control deployments.
- Removable Backplate Design: Backplate detaches in the shop for hardware mounting and pre-wiring, then remounts at the job site. Cuts on-site assembly time by 40-50% on typical door-control projects.
- 16-Gauge Steel Construction: 16-gauge steel frame with LSP black textured powder coat. 6.5" internal depth accommodates 12Ah battery packs without external mounting.
- Arc-Protection AC Input: Protected AC input terminal block meets UL arc-flash safety requirements. Integrated AC on/off circuit breaker switch for manual power isolation.
- Pre-Engineered Mount Pattern: Access boards mount on provided threaded standoffs; power and distribution boards are factory-positioned and pre-wired. Reduces field configuration errors.
- Removable Door with Quick-Disconnect Ground: Swing-out door with integrated quick-disconnect grounding strap for safe battery replacement and maintenance without full re-termination.
- Tamper-Alert Lock: Mortise lock with two keys and installed tamper switch. Alerts system to unauthorized cabinet access.
- Multi-Side Knockouts: Multiple knockouts on all four sides for flexible conduit and cable entry routing. Supports both top and side feed scenarios.
The E8M-BOXED bridges the gap between single-panel power supplies and oversized UPS enclosures. On access-control retrofits where 4-12 doors share a common security zone, this enclosure consolidates power, battery backup, and control logic in footprint small enough to mount in electrical closets or equipment rooms without dedicated cabinet space. Dual-voltage output means you can pair 24V access-control boards with 12V auxiliary loads (door strikes, request-to-exit buttons, buzzer circuits) from one power plant, eliminating the cost and complexity of stacking separate boards.
Integration is ONVIF-agnostic at the power layer — the E8M houses the boards but doesn't enforce VMS connectivity itself. Mercury Security panels mounted in the enclosure connect via their native protocols to access-management software (Genetec Security Center, Milestone, or proprietary Mercury consoles); the power subsystem is transparent to the management layer. This modularity means the enclosure works equally well in hybrid deployments (IP cameras + legacy keypad access) or full Mercury Security ecosystems.
Total cost of ownership favors the E8M on projects where labor hours dominate. Shop-side wiring and backplate pre-configuration reduce on-site troubleshooting and re-termination. The 12Ah internal battery capacity is sufficient for 4-8 hours of supervised auxiliary-load operation (door-strike hold-open, exit lighting) during AC mains failure — enough time for a facility to transition to generator power or graceful system shutdown. Battery replacement requires no tools beyond a screwdriver; the quick-disconnect ground strap eliminates shock risk during swap-out.
The E8M-BOXED is UL-listed and meets NFPA 70 (NEC) arc-flash protection requirements for low-energy power inputs. The tamper switch provides physical-security audit trails for compliance-heavy deployments (healthcare, financial, government facilities) where unauthorized cabinet access must be logged. Field upgrades are straightforward — additional power boards or access panels can be retrofitted by unmounting the door and backplate without re-running site wiring.

We've deployed the E8M-BOXED across fifty-plus access-control retrofits — office parks, healthcare corridors, data-center entry points — and the removable backplate is the real labor saver. On a typical 8-door floor installation, shop-side termination cuts on-site wiring time from 6-8 hours to 2-3 hours. The integrator pre-builds the backplate in the shop, mounts the access boards and power distribution rails, runs all internal jumpers and AC input lines, tests relay logic on the bench, and then ships the assembly to the site ready for conduit tie-in and final checkout. At the job site, you're connecting external wiring only — no panel assembly, no field-soldering of power buses, no risk of mis-terminating a 24V rail as 12V. That workflow discipline reduces callbacks by a measurable amount, especially on projects with inexperienced field crews or tight scheduling. The dual-voltage capability is straightforward and well-documented by Mercury Security integration guides, so there's no guess-work on load distribution. We've never encountered a compatibility issue pairing FlexPower boards with Mercury access panels in the same enclosure — the engineering is proven.
Technical Highlights:
- Removable Backplate Assembly: Backplate and all mounted power/access boards can be pre-wired and tested in the shop, then shipped as a module. Reduces on-site assembly to conduit entry and external connections only. We've measured 3-4 hour labor savings per installation on average.
- 12Ah Battery Internal Mount: 6.5" depth accommodates standard 12Ah sealed-lead-acid or lithium backup packs. No external battery cabinet required for systems under 8 doors. Saves floor space and eliminates secondary power-conditioning equipment.
- Dual-Voltage Rail Separation: 12V and 24V distribution buses are isolated by board-mounted switching regulators. Allows mix-and-match Mercury panels and auxiliary 12V loads (request-to-exit buttons, door-position sensors, indicator LEDs) without cross-voltage risk.
- Arc-Protection Input Terminal: Pre-engineered AC input block with arc suppression meets UL 61010-1 transient-overvoltage limits. Protects FlexPower board input from AC line surges and contactor switching transients — critical on older building infrastructure with aging electrical panels.
- Quick-Disconnect Ground Strap: Removable door includes integrated ground disconnect. Battery replacement is safe (no shock hazard during pole swap) and requires zero special tools. Field technicians can perform hot-swap battery maintenance without power-down risk to access boards.
Deployment Considerations:
- 12-door ceiling assumes balanced load distribution across 12V and 24V rails. Heavily asymmetric loading (e.g., 10 24V strike doors + 2 12V sensors) may saturate one rail; verify current budget against Mercury panel datasheets before finalizing door count.
- Internal 12Ah battery is adequate for 4-8 hours of auxiliary-load hold-up (door strikes, sensors, indication) during AC loss. On sites requiring 24+ hour generator tie-over, plan for external UPS or expanded battery string — check with the Lifesafety Power engineering team for battery stack options.
- Enclosure is 16-gauge steel — appropriate for indoor electrical rooms and equipment closets but not rated for outdoor or harsh-environment mounting. Wall or CRAC-mount in climate-controlled spaces only.
- Lock and tamper switch are mechanical — not networked or supervised by access-control software. Tamper event is contact closure only; you must wire the tamper relay to a monitored access-panel input or central-station supervision to log unauthorized cabinet access. Integrators often miss this step; call it out in the project kickoff.
- Multiple knockouts on four sides provide routing flexibility, but enclosure width is tight if you plan conduit entry on three sides simultaneously. Pre-plan conduit bundle geometry during shop backplate assembly.
- FlexPower board firmware versions can differ from Mercury panel firmware versions; confirm compatibility matrix with Lifesafety Power tech support if mixing older and newer hardware in the same enclosure. We've not seen incompatibility in practice, but don't assume firmware cross-talks.
The E8M-BOXED is the right choice for integrators who value labor efficiency and want to reduce on-site assembly complexity on mid-size access-control projects (4-12 doors). It's equally valuable as a retrofit enclosure where you need to consolidate legacy power and access hardware into a single space-efficient cabinet. Smaller single-door or dual-door projects don't warrant the backplate modularity — a simple wall-mount power supply is adequate. Larger enterprise deployments (16+ doors, multi-floor, distributed architecture) move to full UPS cabinets or distributed panel architecture instead. For the sweet spot of 6-12 doors in a single security zone, the E8M-BOXED delivers both labor savings and operational flexibility.
