The extinguisher detects a fire to extinguish automatically. A fire detector(100) includes a sensing device(31) consisting of a critical temperature resistor a bimetal, and a converter(30) generating electric signals. A nozzel control circuit(32), which receives a electric signals and alarms a fire, commands the nozzel to point the place where a fire is detected by using virtical angular pulse motor(21) and horizonital angular pulse motor(10).
