Abstract

An automatic fire extinguishing system wherein at least two fire detecting sensors are provided. The sensors are disposed at a distance from each other and movable in the horizontal and vertical directions to scan the region to be protected for detecting the angles of a fire source in the horizontal and vertical directions. A distance to the fire source is obtained from the angles of the fire source detected by the respective sensors. A discharge nozzle is set based on the fire source position determined by the angles and the distance of the fire source.
