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

摘要

The present invention provides an automatic sprinkler of fire detector type with an electrically switchable function similar to a fixed-temperature fire detector, and a sprinkler system that can addressably detect a fire in every freely established area with one or more automatic sprinklers of fire detector type and can have a wide variety in system performance thereby. If trying to make such an addressable fire detection to be possible in the existing sprinkler system, every sprinkler must be joined with a fire detector or a waterflow detecting device, however, such a practical difficulty can be satisfactorily settled by the system in accordance with the present invention. In particular, employment of the automatic sprinkler of fire detector type in accordance with the present invention can offer no necessity of waterflow detecting device to the existing wet pipe sprinkler system and lead the existing preaction sprinkler system to a non-wet pipe sprinkler system with no supplemental fire detection system, and, moreover, replace the existing dry pipe sprinkler system with the above non-wet pipe sprinkler system. Therefore, it is expected that a significant turning point in design of the sprinkler system can be made by the present invention.
