The Electromagnetic overhead door closers are suitable for fire doors as CE marked and tested correctly to BS EN 1155. Often in normal daily use the closer is set to the swing free function, so that it is not self closing. When set to the hold open function these closers will hold the door at around 90 degrees. After fire alarm has been triggered, both hold open & swing free door closers will resume operation and close the door like a conventional door closer.
We stock power supply units ideal for installations with electronic door closers.
