Claims

[Scope of Claim for Utility Model Registration] (1) A fire detector and a water injection nozzle are installed in each room to be monitored for fire occurrence in the building, and connected to a water supply source based on the output signal from the fire detector. In the automatic fire extinguishing system that supplies pressurized water from the pump to each of the water injection nozzles, a first manifold that distributes pressurized water from the pump to a plurality of main pipes is provided between the pump and the water injection nozzles; A second manifold is provided which distributes the pressurized water in the main pipe coming out from the manfold to a plurality of sub pipes connected to each water injection nozzle, and the second manifold operates independently for each main pipe and each sub pipe. An automatic fire extinguishing system characterized by being equipped with an electromagnetic on-off valve. (2) An operation indicator is provided on the control panel of the fire extinguishing system to display the operating status of each electromagnetic on-off valve, and each terminal of each electromagnetic on-off valve is connected to the control unit that controls the operation of each electromagnetic on-off valve. 2. The automatic fire extinguishing system according to claim 1, wherein a test circuit for selectively connecting an operating power source is provided, and a changeover switch for switching the connection of the test circuit is provided on the control operation panel.
