As part of an electronic access control system, the selection of the most appropriate means of holding the door in the locked position is essential if the system is to operate to its optimum level.  Wherever possible, components of a system should be selected carefully. 

Ingersoll Rand Security Technologies’ face to face electromagnetic locks utilise magnetic forces to maintain a powerful bond between a frame-mounted magnet and door-mounted armature.   They are intrinsically fail safe making them ideal for emergency escape doors; as soon as a magnet is de-energised, the door automatically allows free egress.
