摘要： PROBLEM TO BE SOLVED: To provide an automatic fire extinguishing system which is suitable for extinguishing a fire of cable connecting sections or the like installed in utility tunnels.
SOLUTION: The automatic fire extinguishing system for extinguishing the fire of the cable connecting section 11 or the like in the utility tunnel with use of suitable fire extinguishing agents, is provided with a fire detection sensor which is composed of smoke detecting sensors 13 and infrared flame detecting sensors 14 thereby detecting the fire when detecting both the smoke and the flame, spray nozzles 15 for spraying extinguishing agent which are predisposed toward fire breakout supposed positions such as cable connecting section 11 laid in the utility tunnels to spray the extinguishing agents to the fire breakout supposed positions, and extinguishing agent spray devices 18 for feeding the extinguishing agents to injecting nozzles 15 through actuations of the fire detecting sensor. According to the present invention, owing to pre-specification of extinguishing objects, the fire in the utility tunnels can securely and immediately be extinguished even with a little amount of extinguishing agents.
