SOLUTION: In the case of application to a ballpark 21, a space under surveillance 22 is divided into a plurality of blocks 23, and discharge guns 3E to 3H, each taking charge of each of first to fourth divided spaces 22A to 22D, are arranged outside the divided spaces 22A to 22D. For example, if a fire is detected by a fire detector 1D, the origin of fire is calculated on the basis of information on the origin of fire, a predetermined block corresponding to the origin of fire, for example 23D, is distinguished, and a discharge gun 3H to take charge of a relevant divided space 22D is selected. Further, in case the space under surveillance 22 is divided with mounting a partition comprising a partition curtain 24, discharge guns at the both sides of the partition curtain 24 are selected at the same time or successively, if the origin of fire is judged to be inside an area of partitions at the both sides of the partition curtain 24.
