ZKTeco EML280-2 Magnetic Lock 280 kg / 600 lbs, 2-Wire (EM Lock)

Overview

The ZKTeco EML280-2 is an electromagnetic lock, often called an EM lock or maglock, that holds a single door shut until the access system releases it. It is rated at 280 kg (600 lbs) and fits glass, wooden, fireproof, sliding and metal doors. The “-2” means two wires, power only, which makes it the simpler and cheaper of the two EML280 versions to install.

Is it right for you?

• It suits an office, flat or shop door where the controller does not need to know whether the lock is engaged.
• If you want the access controller to confirm the door is locked, choose the EML280-5, which adds a lock signal output.
• For a pair of doors, the EML280D-2 holds both leaves from one body.
• A frameless glass door or a narrow door needs a bracket to carry the lock and armature plate.

Key features

• 280 kg (600 lbs) holding force.
• Two-wire connection, power only, with no signal wiring to terminate.
• Selectable 12 V DC or 24 V DC, so it matches whichever supply the access panel provides.
• Draws 0.43 A at 12 V or 0.29 A at 24 V, which matters when sizing a battery-backed supply.
• Aluminium body, 250 × 48 × 27 mm, 1.66 kg, with a 180 × 38 × 11 mm armature plate.
• Surface mounted on glass, wooden, fireproof, sliding and metal doors.

What else you need

• A 12 V or 24 V DC supply with enough current, battery backed if the door must stay locked through a power cut.
• An access controller or terminal to release it, and an exit button or sensor on the inside.
• A bracket, only on a frameless glass door (MLB-280L or MLB-280U) or a narrow door (MLB-280LZ).

Installation

An access control installer should fit it. The lock body mounts on the frame and the armature plate on the door leaf, aligned so the two meet squarely when the door closes. Wiring is two cores to the power supply, switched by the controller.

Before you buy

• Being an electromagnet, it releases the moment power is removed. That suits an escape route, but it means the door is open during a power cut unless the supply is battery backed.
• No lock signal output: order the EML280-5 if you need door status at the controller.
• Glass and narrow doors need a bracket.
