Electro magnetic locksElectro-magnetic locks are secure, simple, reliable and require only minimal power.When the lock is energised, it creates a strong magnetic field, which holds a door shut with a force of 750lbs. When the power is cut, the field collapses and the door opens. There are no moving parts. Magnetic shearlocksIn this type of lock, the plate is fitted into the top edge of the door and the magnet fits in the door frame immediately above it. When the lock is energised, the magnet pulls the plate up out of the door and holds it securely. Shearlocks can be used for swinging doors and for doors with no overhead clearance. And when the door is closed, the lock is completely invisible.Solenoid locksA solenoid lock works like a conventional morticed latch lock – except the tongue of the lock is activated by a magnetic field, rather than a key. They can be used in a wide range of situations – including double-action doors.DropboltsDropbolts are fitted into a door or gate and drop down into a hole to secure it. They can fail in either the safe or secure position.Door contactsNowadays, most door contacts are integrated with the locking mechanism. They report to the access control system on the condition of the door, revealing when it has been wedged open, forced open or left open too long.Standalone door contacts would be fitted on doors which do not need full access control e.g. the doors to the roof of a building. | ||||||||||||||||
