ABSTRACT:
A fire detecting/extinguishing apparatus according to the present invention is comprised of a fire detecting unit which monitors to detect a fire within a monitoring area, the fire detecting unit stepwise scanning in a vertical direction while scanning the fire monitoring area in the vertical direction at each step of the horizontal scanning; a water discharging unit having a water discharging nozzle for discharging water to the monitoring area, the water discharging unit being rotatable in the horizontal direction, the water discharging unit being directed toward a position of the fire based on the fire detection by the fire detecting unit; a swinging unit which swings the water discharging unit in the horizontal direction; and a casing in which the fire detecting unit and the water discharging unit are housed as a single unit. Further, the apparatus of the present invention includes a cover fixed to a side of the water discharging nozzle which is opposite to the side of the water discharging nozzle. The cover is capable of rotating together with the water discharging unit, and the cover is flush with a front wall of the casing when the water discharging nozzle is housed in the casing.
