AUTOMATIC FIRE EXTINGUISHING DEVICE

PURPOSE:To perform a fire extinguishing efficiently, and at the same time, make the installation work or maintenance of the conduit extremely easy by providing a nozzle which is closed at the time of non-fire and opened at the time of fire and a sensor nozzle which detects the generation of a fire, at the tip of a conduit from a fire extinguishing agent storage container. CONSTITUTION:A conduit 5 is connected to a fire extinguishing agent storage container 1, and the conduit 5 is branched and extended to a plurality of fire extinguishing objective locations. However, at the upper end of the storage container 1, an actuating part 2 which does not release the fire extinguishing agent in the conduit 5 under a monitoring condition and releases the fire extinguishing agent in the conduit 5 by opening the storage container 1 by an electric signal at the time of fire, is provided. Also, at each tip of the conduit 5, a sensor nozzle 10, for which a sensor to emit a signal of the generation of a fire electrically and a fire extinguishing nozzle are integrated, is attached. In addition, if a pressure switch is attached to the storage container 1, a storage pressure reduction alarm for the storage container 1 can be obtained by the reduction of the output of the fire extinguishing agent releasing.
