摘要： Provided is an air suction-type fire detection system and a detection method thereof, which are capable of early detection of a fire location through smoke concentration monitoring. Particularly, in the system, an air suction-type fire detection system capable for early detection of a fire location through smoke concentration monitoring, the air suction-type fire detection system are provided, which includes: an air suction-type fire detector that is fitted to the outside of a chamber needing fire detection and detects fire through an inflow of air inside a warehouse; a suction line that is fitted to the inside of the warehouse and sucks air inside the warehouse in real time; a connection line that links the suction line and the fire detector; and a pump that is furnished in one side of the connection line and supplies power to draw air from inside the warehouse into the suction line.

摘要： A fire extinguishing system for a tire of a vehicle is capable of effectively responding to a fire in all tire areas of the vehicle, and of spraying fire extinguishing agent selectively only for the tire having the fire, thereby performing effective fire extinguishing. The fire extinguishing system includes: a fire detection sensor configured to detect the fire in the tire of the vehicle; a fire control unit configured to receive a signal output from the fire detection sensor and to output a control signal for spraying fire extinguishing agent when the fire control unit determines a fire occurrence; and a plurality of fire extinguishing agent sprayers configured to spray the fire extinguishing agent toward the tire having the fire according to the control signal output by the fire control unit, in a state of being filled with the fire extinguishing agent therein.

摘要： The current invention is a remotely controlled fire suppression system that pipes water directly from a water main to a water cannon. The water can be sprayed hundreds of feet from the cannon, which can change direction and angle of spray. The suppression system is attached to a water main, with an electric valve that allows control of pressure and flow rate. The water cannon is attached at the top of the water pipe, which can rise 3′-30′ or more above the ground. The water cannon can be fixed or change direction and angle. The water valve and water cannon are remotely controlled, by wired or wireless communication. Units are identified by GPS and address, allowing individual or government units to use devices at fire sites.

摘要： A fire retardant delivery system for use with a source of carrier for protection from wildfire is provided. The system includes a retardant tank for storing a fire retardant. The retardant tank is in fluid communication with the source of carrier. A metering valve is constructed and arranged to meter a flow of fire retardant injected into the carrier discharged from the source of carrier to maintain a predetermined proportion of fire retardant to carrier, thereby creating a fire retardant and carrier mixture. At least one distribution nozzle is configured to deliver the fire retardant and carrier mixture to a desired area.

摘要： The present invention discloses a fire extinguishing system for a battery pack, including a detection control apparatus, a fire suppression apparatus, and a hydrant water extinguishing apparatus. The detection control apparatus is disposed inside or outside a battery pack. The fire suppression apparatus and the hydrant water extinguishing apparatus are disposed outside the battery pack. The detection control apparatus is connected to the fire suppression apparatus. The hydrant water extinguishing apparatus is connected to the fire suppression apparatus. Beneficial effects: It is ensured that initial fire can be suppressed and later reignition can be resolved, so that fire extinguishing is adequate. Fire is directly extinguished at a core position inside the battery pack. An exhaust filter device gains valuable time after initial fire extinguishing.

摘要： A fire detection device and method therefor are able to provide automatic activation so as to extinguish a fire. The fire detection can be rapid and temperature-based. In one embodiment, a heat collector can be provided to enhance thermal responsiveness. Activation of the fire detection device can be electrically induced to release an extinguishing agent at the fire. The activation can be protected such that it is durable and unaffected by vibrations.
