Access control door magnets can be used across various domestic and commercial applications and offer solutions where a high security level is required. In some environments doors are required to be held open under normal conditions and them automatically released in the event of fire alarms and evacuation. Door magnets ensure that doors close automatically and are securely closed. Magnetic door holders are suitable for a range of applications, such as schools, nursing homes, and hospitals, to form part of a high-quality security system.

How to install a door magnet?
Generally the electromagnet is attached to the door frame, whilst an armature plate is attached to the door itself. Occasionally brackets may be needed to ensure the magnet is in the correct position for contact with the plate. To achieve the optimal pull force of 100%, a contact area must be achieved using the recommended armature plates.

Where would an access control door magnet be useful?

• Professionals and individuals intending to increase the safety of their property


• Essential for where a door must close automatically in the event of an emergency, for example in nursing homes, hospitals, schools, and industrial premises


• Industrial automation and fire safety, for example locking doors in the event of fire alarms
