A system extinguishing agent (for example, nitrogen gas) is pressurized and filled at a monitoring pressure (for example, 0.7 MPa) greater than 0.5 MPa, and the operating pressure of the secondary pressure drop monitoring pressure switch 6 is 0.5 MPa or more, and the monitoring pressure. Less than .
From the above configuration, the operation of the sprinkler head 3 causes the pre-actuated alarm valve 1 to open and release the water, so that nitrogen gas suppresses the spread of the fire. Therefore, a fire extinguishing effect equivalent to that of a general sprinkler fire extinguishing equipment can be obtained, so that the alarm valve, the pipe diameter, the size of the pump, and the number of sprinkler heads simultaneously opened can be made the same as the general sprinkler fire extinguishing equipment. In addition, this makes it easier than ever to change the pipe diameter or the like when changing a property in which a general sprinkler fire extinguishing facility is constructed to a pre-operated sprinkler fire extinguishing facility at the time of renewal.
Moreover, since the secondary side pipe is pressure-filled with the fire extinguishing agent, the oxygen concentration in the secondary side pipe can be lowered, and the inner surface of the secondary side pipe is hardly corroded.

The operating pressure of the secondary pressure drop monitoring pressure switch 6 is 0.5 MPa or more and less than the monitoring pressure.
With the above configuration, when the sprinkler head 3 is activated, the fire extinguishing agent suppresses the expansion of the fire until the pre-actuated alarm valve 1 opens and discharges water. Therefore, a fire extinguishing effect equivalent to that of a general sprinkler fire extinguishing equipment can be obtained, so that the alarm valve, the pipe diameter, the size of the pump, and the number of sprinkler heads simultaneously opened can be made the same as the general sprinkler fire extinguishing equipment. In addition, this makes it easier than ever to change the pipe diameter and the like when changing a property with a general sprinkler fire extinguishing facility to a dry sprinkler fire extinguishing facility at the time of renewal.
Moreover, since the secondary side pipe is pressure-filled with the fire extinguishing agent, the oxygen concentration in the secondary side pipe can be lowered, and the inner surface of the secondary side pipe is hardly corroded.
