PURPOSE:To shorten the fire extinguishing time by supplying a current to a blower motor through a normally open contact of a changeover contact of a seismic automatic fire extinguisher and a first temperature switch thereof when the combustion device is overthrown and fire is extinguished. CONSTITUTION:A seismic automatic fire extinguisher 28 operates, a changeover contact 28a is switched from point (i) to (j), supply of current to a solenoid 6 is stopped, and holding of a lever 4 is released and fire is extinguished. Upon this occasion, different from the time of ordinary fire extinguishment, supply of current to an ignition heater 25 is not carried out. Furthermore, a current is supplied to a blower motor 17a through contact (j) of the seismic automatic fire extinguisher 28, a temperature switch 27 and the contact (o) of a relay 39 (as the relay 39 is not supplied with a current, the contacts are switched from (p) to (o). Thus, the blower motor 17 acts to blow out the small flames remaining in the combustion part at the time of the fire extinguishment. When the temperature of the combustion part falls and the temperature switch 27 is opened, supply of current to the blower motor 17a is stopped. |
