TimeWatch EML-1200-DL-F — 1200 lbs Electromagnetic Door Lock (Double-Door)

Description

A Bengaluru biotech lab’s facilities lead is locking down ISO-cleanroom doors that need to stay shut for biosafety, but must release the instant a fire alarm trips. The cleanroom anteroom door has to hold securely against staff leaning into it during gowning, yet drop to fail-safe the moment power is cut. The TimeWatch EML-1200-DL-F is built for exactly this. 1200 lbs / 545 kg of holding force, double-door (dual-leaf) configuration, 12V / 24V DC operation, fail-safe by design — releases the instant power is cut so the door never traps anyone behind it.

Why integrators specify the TimeWatch EML-1200-DL-F

The TimeWatch EML-1200-DL-F is the electromagnetic lock integrators reach for when an Indian site needs a double-door (dual-leaf) door lock with documented holding force and clean access control integration. 1200 lbs / 545 kg is the brief, and the TimeWatch EML-1200-DL-F delivers it on a surface-mount housing that fits standard door-and-frame geometry across wood, aluminium and metal-clad doors. The TimeWatch EML-1200-DL-F 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. No protocol conversion, no firmware hack, no late-night call to the integrator over wiring drift.

For specifiers, the TimeWatch EML-1200-DL-F 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 1200 lbs / 545 kg per leaf, 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 TimeWatch EML-1200-DL-F is rated at 1200 lbs / 545 kg per leaf, which is the number that goes on the access control submittal sheet and the number the insurance auditor cross-checks. The TimeWatch EML-1200-DL-F runs on 12V / 24V DC, drawing typical surface-mount EM lock current — comfortably inside the budget of a standard 12V DC access control power supply with battery backup. Anodised aluminium alloy housing resists the daily knocks of a high-traffic door and is the housing finish integrators specify for Indian commercial deployments where humidity, dust and the occasional monsoon damp matter.

The TimeWatch EML-1200-DL-F 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 double-door (dual-leaf) installation, the geometry is simple: one armature per leaf, one magnet body per leaf, and a single relay drive from the access controller drops both magnets in unison on a valid release signal.

Door compatibility

The TimeWatch EML-1200-DL-F is a double-door (dual-leaf) electromagnetic lock — designed for double-leaf (dual-leaf) door installations where both leaves of the door need to hold together as one. The TimeWatch EML-1200-DL-F 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 TimeWatch EML-1200-DL-F 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 TimeWatch EML-1200-DL-F.

Access control integration

The TimeWatch EML-1200-DL-F wires into any standard access controller’s lock output relay — the kind of relay every Wiegand and IP access controller in the eSSL, ZKTeco, BioMax, 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 (or 24V DC) to the TimeWatch EML-1200-DL-F, 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 TimeWatch EML-1200-DL-F 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. The integrated door status feedback signal on the TimeWatch EML-1200-DL-F wires back to the access controller as a door-open / door-closed input — the controller logs the state, alarms on door-held-open, and writes a clean audit trail entry for every door cycle.

What buyers usually ask before ordering

What holding force do I need for my door?
For interior office doors and meeting room doors, 600 lbs (270 kg) is the standard specification. For main entry doors, server rooms, strongrooms and high-security doors, 1200 lbs (545 kg) is the brief. The TimeWatch EML-1200-DL-F is rated at 1200 lbs / 545 kg, which puts it at the high-security 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 TimeWatch EML-1200-DL-F 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 TimeWatch EML-1200-DL-F 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 TimeWatch EML-1200-DL-F is driven by a dry-contact relay output on the access controller, which is what every standard Wiegand-and-IP access controller in the eSSL, ZKTeco, BioMax, Matrix and TimeWatch range provides on the lock output. No protocol conversion, no interface board. Wire the controller’s lock relay to the TimeWatch EML-1200-DL-F’s 12V DC input, and the TimeWatch EML-1200-DL-F responds to every valid access decision.

What’s in the box — bracket included?
The TimeWatch EML-1200-DL-F 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 TimeWatch EML-1200-DL-F.

Can it be used on glass / wood / metal doors?
Yes to all three. The TimeWatch EML-1200-DL-F 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 TimeWatch EML-1200-DL-F on glass office doors and reception doors.
