When the motor-driven valve 17 is closed and the fire hydrant 12 is used, the water discharge from the water discharge type head 11 is stopped.

  Since the water discharge type head 11 discharges water from the vicinity of the left and right wall surfaces of the sales floor 1 or from the vicinity of the ceiling toward the inside of the sales floor 1, products are piled up on the sales floor 1, or are high. Even if it is displayed on display shelves 4 and 7 or panels for advertisements and information are suspended from the ceiling, these are less likely to cause watering and effectively extinguish the fire that occurred at sales floor 1. Can do. In addition, when water discharge from the water discharge type head 11 does not lead to complete fire extinguishing, the fire can be completely extinguished by water discharge by the fire hydrant 12. Even in such a store fire extinguisher 10 that combines the water discharge head 11 and the fire hydrant 12, when the fire hydrant 12 is used, the water discharge from the water discharge head 11 is stopped, so that the water discharge head 11 and the fire hydrant are stopped. Compared to the facility that simultaneously discharges water from the pump 12, the pump 16 having a low discharge pressure can be used, the diameter of the pipe can be reduced, and the equipment cost can be reduced.

  The water discharge type head 11 is installed facing the innermost wall passage 5 of the sales floor 1 and each sub-passage 8 parallel thereto, and each of the passages 5 from the left and right wall surfaces of the sales floor 1 or the ceiling near the wall, By discharging water sideways toward the inside of the sales floor 1 aiming at 8, water can easily reach the fire source by water discharge by the water discharge type head 11, so that effective fire extinguishing can be performed and water discharge Since water can reach the fire source far from the mold head 11, the number of water discharge type heads 11 can be reduced, and the equipment cost can be reduced.

  As for the fire detector 18, the space on the left side of the sales floor 1 and the space on the right side of the sales floor 1 are monitored so as to monitor the innermost side wall 5 of the sales floor 1 and each of the sub-passages 8 parallel thereto. By installing on the ceiling surface above the main passage 6, the view from the fire detector 18 becomes good, so that effective fire detection can be performed and the detection performance of the fire detector 18 can be used effectively. Therefore, the number of fire detectors 18 installed can be reduced and the equipment cost can be reduced.
