Electromagnetic Gate Lock, 300kg Holding Force, Fail Open, 12/24V DC, Bolt-On, Black

This is a bolt-on electromagnetic gate lock with 300kg of holding force: a powerful magnet in one black aluminium housing on the post holds an armature plate in a matching housing on the gate, so the gate stays shut until the access control cuts the power. The two housings close together at the gate's edge and their rounded ends form the pull handles, so there is nothing else to fit. It is fail open, releasing the instant power is removed, which suits escape gates and fire alarm release. It runs on 12 or 24V DC and bolts on with Quick-Fix fixings, with no welding. The price shown is for one complete lock in black.

Why use a magnetic lock

No moving parts to wear. A magnetic lock has no latch or bolt to bend, stick or go out of line as the gate settles, so it suits busy gates that open hundreds of times a day.

Holds 300kg. The holding force is tested on every lock before it leaves the factory, and a raised edge on the magnet housing stops a crowbar being forced between the magnet and the plate.

Releases cleanly. An anti-residual magnetism kick-off pushes the plate away the moment the power is cut, so the gate opens straight away instead of sticking.

Fail open for safety. With no power the lock releases, so an escape gate always opens in a power cut or when the fire alarm drops the supply.

Built for outdoors. Powder-coated aluminium housings with a two-layer protective coating, salt spray tested for 500 hours to ISO 9227 and certified by SGS.

Bolt-on fitting. Quick-Fix bolts fix the housings through a few drilled holes, so there is no welding of lock boxes onto the gate.

Where it is used

Pedestrian gates with card, fob, keypad or intercom entry at offices, schools, hospitals, blocks of flats, industrial yards, car parks and sports grounds, and escape gates in perimeter fences that must release on a fire alarm.

What else you need

Choosing the right option

Choose a magnetic lock for powered access control on a busy gate, where you want no latch to wear and a gate that releases cleanly from a card reader, keypad or intercom. Because it is fail open, the gate is unlocked whenever the power is off, so use a battery-backed power supply where the gate must stay secure in a power cut, or choose a mechanical lock with a fail-close electric keep instead. Fit self-closing hinges or a gate closer so the gate swings back to the magnet every time.

Fitting and care

Hang the gate and fit its closer first. Mark the housings on the gate stile and post at the closing edge, drill the holes and fix them with the Quick-Fix bolts, lining the armature up flat against the magnet. Run the cable through a cable loop if it crosses to the gate and connect it to a 12 or 24V DC supply through your access control. Mains and fire alarm connections must be made by a qualified electrician. Keep the magnet and plate faces clean, and test the holding and release regularly.
