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.
