eSSL MRC-80 — Magnetic Door Contact Sensor for EM Lock Access Control (Single-Door)
10 in stock (can be backordered)
Description
A Kolkata hotel chain’s IT lead is rolling out maglocks on the back-of-house corridor doors at three properties, and the existing access controller is an eSSL panel the chain standardised on five years ago. The new door locks have to drop in on the same wiring, the same power supply and the same controller logic — and the access control system needs reliable door-open / door-closed status from the door side, not just the lock side. The eSSL MRC-80 is built for exactly this. Magnetic door contact sensor for any single-door electromagnetic lock installation, 12V / 24V DC operation, fail-safe wiring — feeds clean status into the access control panel so the door’s state is logged on every cycle.
Why integrators specify the eSSL MRC-80
The eSSL MRC-80 is the magnetic door contact sensor integrators reach for when an Indian site needs reliable door-status monitoring alongside an electromagnetic door lock — the kind of sensor that completes a maglock access control installation and gives the controller real-world visibility into whether the door actually closed after every release. The eSSL MRC-80 pairs cleanly with the access controller already on site — wires straight into the door contact input on any eSSL controller and on standard third-party access panels. No protocol conversion, no firmware hack, no late-night call to the integrator over wiring drift.
For specifiers, the eSSL MRC-80 is the standard companion to a non-feedback EM lock — when the maglock itself does not provide door status feedback, the eSSL MRC-80 gives the access control system the door-open / door-closed signal it needs for held-open alarms and forced-entry alerts. That is the line every facilities lead and every integrator asks about first when specifying the EM lock access control bill of materials.
Holding force & mechanical build
The eSSL MRC-80 is a magnetic door contact sensor — not itself the locking element, but the partner sensor that the access controller reads to confirm the door is closed after the EM lock re-engages. Holding force on the paired electromagnetic lock is whatever the maglock itself provides (typically 270 kg / 600 lbs for office doors and 545 kg / 1200 lbs for high-security doors); the eSSL MRC-80 simply monitors the door’s open/close state. The eSSL MRC-80 runs on 12V / 24V DC, drawing negligible current — comfortably inside the budget of a standard 12V DC access control power supply with battery backup. Durable anodised housing resists the daily knocks of a high-traffic door.
The eSSL MRC-80 is a surface-mount magnetic contact — the magnet half fixes to the door leaf, the reed half fixes to the frame, and the two close to within a few millimetres on door close. No mortising, no door cut-outs, no irreversible damage to the door slab. For a single-door EM lock installation, the geometry is simple: pair the eSSL MRC-80 with the maglock at the top of the door, and the access controller reads both the lock state and the door state together.
Door compatibility
The eSSL MRC-80 mounts on single-door and double-door installations alongside any electromagnetic door lock — surface-mount on wood doors, aluminium-framed glass doors and metal-clad doors with the standard bracket geometry. For glass doors, fix the magnet half to the glass with the adhesive-backed bracket; for wood and metal doors, screw-fix in the standard way.
Frame compatibility is forgiving: the eSSL MRC-80 reed switch closes reliably across a small gap, so small misalignments between door and frame do not affect the contact signal. For Indian door frames that are not always machine-perfect, that tolerance matters. Mounting hardware ships with the door contact sensor; for unusual door types, alternative brackets are available alongside the eSSL MRC-80.
Access control integration
The eSSL MRC-80 wires into any standard access controller’s door-contact input — the kind of input every Wiegand and IP access controller in the eSSL, ZKTeco, BioMax, Matrix, Honeywell and TimeWatch range carries on its door-monitor terminal. The integration is dry-contact simple: door closed, contact closed; door open, contact open. The access controller reads the state and combines it with the lock-state to generate alarms — door-held-open, door-forced-open, door-closed-confirmed.
Fail-safe is built into the broader access control system, not the door contact itself — the EM lock alongside the eSSL MRC-80 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. The eSSL MRC-80 simply reports the resulting door state to the controller, so the audit trail is complete. No code violation, no trapped occupant.

What buyers usually ask before ordering
What holding force do I need for my door?
The eSSL MRC-80 itself is a door contact sensor — the holding force comes from the EM lock it pairs with. For interior office doors, pair the eSSL MRC-80 with a 270 kg (600 lbs) maglock; for main entry doors, server rooms, strongrooms and high-security doors, pair it with a 545 kg (1200 lbs) maglock. 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?
The paired electromagnetic lock is fail-safe by design — power cut, magnet released, door open. That is the standard Indian fire-safety expectation for an electromagnetic door lock. The eSSL MRC-80 simply reports the door state. If the access controller crashes, the building loses power, or the access control PSU fails, the EM lock releases and the eSSL MRC-80 records the resulting door-open state. No trapped occupants, no fire code violation.
Will it work with our existing access controller (Wiegand / dry contact)?
Yes — the eSSL MRC-80 is a passive dry-contact reed sensor that wires into the door-contact input on any access controller, which is what every standard Wiegand-and-IP access controller in the eSSL, ZKTeco, BioMax, Matrix and TimeWatch range provides. No protocol conversion, no interface board. Wire the eSSL MRC-80 contacts to the controller’s door-monitor terminal, and the access control system reads the door state on every cycle.
What’s in the box — bracket included?
The eSSL MRC-80 ships with the magnet half, the reed half and the standard surface-mount brackets and fixings. For glass doors, frameless glass installations and unusual door types, alternative brackets are sold separately — tell us your door type when ordering and we ship the right bracket alongside the eSSL MRC-80.
Can it be used on glass / wood / metal doors?
Yes to all three. The eSSL MRC-80 mounts to wood doors and metal-clad doors directly with the standard bracket. For glass doors (framed and frameless), the adhesive-backed mounting option fixes the magnet half cleanly to the glass — and that is the standard Indian commercial fit-out for the eSSL MRC-80 alongside an EM lock on glass office doors and reception doors.
