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.
