BioMax EL-280GD — 280 kg Electromagnetic Door Lock (Single-Door)
10 in stock (can be backordered)
Description
A Faridabad automotive plant’s maintenance head has 4 workshop doors needing industrial-grade maglocks — high holding force, dust-resistant, surviving the daily slam of shift-change traffic. The site’s existing electric strikes have failed three times this year on the same doors. The BioMax EL-280GD is built for exactly this. 280 kg of holding force, single-door flush-mount configuration, 12V DC operation, fail-safe by design — releases the instant power is cut so the door never traps anyone behind it.
Why integrators specify the BioMax EL-280GD
The BioMax EL-280GD is the electromagnetic lock integrators reach for when an Indian factory, workshop or commercial site needs a single-door door lock with documented holding force and clean access control integration. 280 kg is the brief, and the BioMax EL-280GD delivers it on a surface-mount housing that fits standard door-and-frame geometry across wood, aluminium and metal-clad doors. The BioMax EL-280GD pairs cleanly with the access controller already on site — the relay-driven lock output drops the magnet, the door opens, the magnet re-engages on close. Compatible with all BioMax controllers and standard third-party access panels — no protocol conversion, no firmware hack, no late-night call to the integrator over wiring drift.
For specifiers, the BioMax EL-280GD is a known-quantity maglock — the kind of EM lock that ships with the access control bill of materials and never becomes the line item the project manager has to apologise for. Holding force is rated at 280 kg, and the fail-safe behaviour is the standard Indian fire-safety expectation: power cut, door released, no ambiguity. That is the line every facilities lead, every fire officer and every insurance auditor asks about first.
Holding force & mechanical build
Holding force on the BioMax EL-280GD is rated at 280 kg, which is the number that goes on the access control submittal sheet and the number the insurance auditor cross-checks. The BioMax EL-280GD runs on 12V DC, drawing typical surface-mount EM lock current — comfortably inside the budget of a standard 12V DC access control power supply with battery backup. Durable construction rated for heavy commercial daily use, and the housing finish integrators specify for Indian commercial and industrial deployments where humidity, dust and the occasional monsoon damp matter.
The BioMax EL-280GD is a surface-mount electromagnetic lock — the armature plate fixes to the door leaf, the magnet body fixes to the frame, and the door pulls into the magnet face on close. No mortising, no door cut-outs, no irreversible damage to the door slab. For a single-door installation, the geometry is simple: one armature on the leaf, one magnet body on the frame, and a single relay drive from the access controller drops the magnet on a valid release signal — simple 2-wire or 4-wire installation, no specialist tools needed.
Door compatibility
The BioMax EL-280GD is a single-door electromagnetic lock — designed for single-leaf door installations across reception, office cabin, server room, workshop and corridor doors. The BioMax EL-280GD mounts to wood doors, aluminium-framed glass doors and metal-clad doors with the standard surface-mount bracket geometry. For glass doors and frameless glass installations, a U-bracket or L-bracket accessory (sold separately) gives the armature a clean fixing surface without through-bolting the glass.
Frame compatibility is the usual story for an EM lock: the magnet body wants a flat fixing surface on the frame head, with the armature falling directly under it on the door leaf. The BioMax EL-280GD is forgiving of small misalignments — a few millimetres either way and the door still pulls in cleanly to the magnet face. For Indian door frames that are not always machine-perfect, that tolerance matters. Mounting hardware ships with the maglock; brackets for glass and inward-opening doors are the add-on most integrators pre-order alongside the BioMax EL-280GD.
Access control integration
The BioMax EL-280GD wires into any standard access controller’s lock output relay — the kind of relay every Wiegand and IP access controller in the BioMax, eSSL, ZKTeco, Matrix, Honeywell and TimeWatch range carries on its lock output. The integration is dry-contact simple: the controller pulls the relay, the relay drops 12V DC to the BioMax EL-280GD, the magnet releases, the door opens. On close, the controller re-energises the line and the magnet re-engages. NO/NC configuration is the standard fail-safe wiring — Normally Open contact, energised to lock, de-energised to release — which is the configuration every Indian fire-safety code expects on an electromagnetic door lock.
Fail-safe is the non-negotiable behaviour. The BioMax EL-280GD releases on power loss, every time. That is fire-safety code compliant — the access control system can fail, the controller can crash, the building’s power can drop, and the door is open. No code violation, no trapped occupant. Door status feedback is not wired on this variant — if the access control system needs door-open/closed monitoring, a separate door contact (a magnetic reed sensor) wires into the controller alongside the BioMax EL-280GD.

What buyers usually ask before ordering
What holding force do I need for my door?
For interior office doors and meeting room doors, 280 kg (600 lbs equivalent) is the standard specification. For main entry doors, server rooms, strongrooms and high-security doors, 545 kg (1200 lbs equivalent) is the brief. The BioMax EL-280GD is rated at 280 kg, which puts it at the standard commercial end of the EM lock range — match the holding force to the door’s threat model, and add a 25 percent margin for the daily lean of high-traffic users.
Is the lock fail-safe — does it release on power loss?
Yes. The BioMax EL-280GD is fail-safe by design — power cut, magnet released, door open. That is the standard Indian fire-safety expectation for an electromagnetic door lock, and it is the wiring configuration the BioMax EL-280GD ships ready for. If the access controller crashes, the building loses power, or the access control PSU fails, the door is open. No trapped occupants, no fire code violation.
Will it work with our existing access controller (Wiegand / dry contact)?
Yes — the BioMax EL-280GD is driven by a dry-contact relay output on the access controller, which is what every standard Wiegand-and-IP access controller in the BioMax, eSSL, ZKTeco, Matrix and TimeWatch range provides on the lock output. No protocol conversion, no interface board. Wire the controller’s lock relay to the BioMax EL-280GD’s 12V DC input, and the maglock responds to every valid access decision.
What’s in the box — bracket included?
The BioMax EL-280GD ships with the magnet body, the armature plate and the standard surface-mount hardware. For glass doors, frameless glass installations and inward-opening doors, specialist U-brackets, L-brackets and Z-brackets are sold separately — tell us your door type when ordering and we ship the right bracket alongside the BioMax EL-280GD.
Can it be used on glass / wood / metal doors?
Yes to all three. The BioMax EL-280GD mounts to wood doors and metal-clad doors directly with the standard armature bracket. For glass doors (framed and frameless), a U-bracket or L-bracket accessory gives the armature a clean fixing point without through-bolting the glass — and that is the standard Indian commercial fit-out for the BioMax EL-280GD on glass office doors and reception doors.
