ABSTRACT:
An improved fire extinguishing system is proposed which uses both water and a fire extinguisher chemical. When a fire alarm senses an abnormally high temperature, a fire extinguisher will be sprinkled first. Only if this fails to extinguish the fire, water will be sprinkled from the water nozzle. This prevents damage of overdischarge of water. There is no fear of water spreading a fire caused by a flammable liquid.
