AUTOMATIC SPRINKLER OF FIRE DETECTOR TYPE AND SPRINKLER SYSTEM INCLUDING THE SPRINKLER

摘要

An automatic sprinkler of fire detector type being electrically switchable when the sprinkler is opened due to detachment of heat actuatable element from the sprinkler is provided, and, thus, fire-protective signaling and controlling system associated with a sprinkler system including the automatic sprinkler of fire detector type can be activated by electrical switching of the automatic sprinkler of fire detector type when fire occurs. And, in a sprinkler system having non-wet piping network and normally closed deluge valve, it is possible that opening of the deluge valve can be made by electrical switching of the automatic sprinkler of fire detector type.
