PROBLEM TO BE SOLVED: To solve such a problem that conventional fire extinguishing equipment detects, as a water level abnormality, a state where a water surface of a water tank swings and a water level is fluctuated due to an occurrence of an earthquake and warns about abnormality of the water level.SOLUTION: The fire extinguishing equipment includes: a water tank for releasing fire-fighting water via a fire extinguisher; a water level detector that outputs a water level abnormality signal when the water level of the water tank reaches abnormality of the water level; and fire extinguishing control board that warns about abnormality of the water level when detecting the water level abnormality signal. The fire extinguishing equipment further includes an earthquake detector that detects an occurrence of an earthquake and, when the earthquake occurs, cuts off an output of the water level abnormality from the water level detection device for a prescribed time. |
