Door holders are idle for fire and smoke break doors. Typically these doors are equipped with fire rated door closers and fire-rated panic bars. Fire-rated panic bars are not allowed to be outfitted with dogging devices. However, many times the doors are typically left open unless there is a fire, then they should automatically go shut. The Sentry E. Labs electromagnetic door holder can be closed through a Normally Open or Normally Closed signal from an alarm system. It also comes equipped with a manual override button on the magnet that will manually disrupt power to the lock and allow the door to close.
