SMOKE FIRE EXTINGUISHING DEVICE

摘要

PROBLEM TO BE SOLVED: To easily set a sensor part at a location in a monitored area to detect a fire, and to appropriately extinguish a fire by reducing the sensing time.

SOLUTION: A solid fire extinguishing agent to generate aerosol for fire extinction by burning is stored in a casing 12 with a spout 14. A thermo-sensitive cable 20 is connected with a connector to the casing 12, and a pair of signal lines are brought into contact in a short-circuit state by melting of an insulating coating of the cable when receives the heat of the fire. An ignition circuit part in the casing 12 ignites and burns the solid fire extinguishing agent by the energization and overheating of a heater when the short-circuiting of the thermo-sensitive cable 20 laid in the monitoring area is detected, and ejects the aerosol for fire extinction from the spout 14 to the monitored area to extinguish the fire.
