What is electromagnetic door stopper?

Electromagnetic door holders and releasers keep doors open until they are released by fire-alarm systems, 

remote smoke detectors, or other switching devices. They provide a high holding force. In the event of a power 

failure, they release the door to a closed position to keep the facility secure.

Removing the Old Magnetic Door Stop

Use a screwdriver to loosen the screws until they come off. Remove the entire catch assembly and put them aside.
