Electromagnetic door holders will allow a fire door to be held open electro-magnetically allowing a free flow of traffic. In the event of a fire (or power failure), the magnet is released and the door closer will close the fire door securely to help limit the spread of fire throughout a building. This type of door control is ideal for busy corridor doors as found in hospitals or schools.
