A system and a controlling method for extinguishing a fire in a battery of a vehicle is provided for preventing the vehicle from being completely burned out and protecting consumer's physical assets by injecting cooling water of a water cooling system when a fire occurs in a battery to extinguish the fire of the battery at an early stage and by supplying an external cooling material from outside of the vehicle to extinguish the fire of the battery when the fire of the battery is not extinguished at the early stage.

There are a large number of different sprinklers which are used in firefighting installations, in particular a water extinguishing installation having a blocking and an enabled state, wherein the extinguishing fluid-conducting element has a fusible link opening element having a predetermined electrical resistance, wherein the fusible link opening element is integrated in an electrical circuit which has a switch (S) and through which when the switch (S) is closed there flows a current by which the fusible link opening element is opened.

A process for the elimination of thermal interferences in the infrared and video fire detection at an early stage in waste incineration plants, recycling facilities, warehouses and the like. The process is characterized by an additional noise and vibration analysis, by measuring the noise level of vehicles situated in the area to be detected or other thermal interference sources, with a distinction in measuring the noise level between day mode and night mode. The volume thresholds can thus be determined and be used as a threshold for determining whether a fire extinguishing sequence should be triggered.

The invention relates to a fire extinguishing system comprising an extinguishing agent supply, a distribution system at least one spray head and at least one valve mounted between the distribution system and the at least one spray head, characterized in that the at least one valve comprises an automated actuator. The invention further relates to a method of fighting a fire using this system, comprising the following steps: a) Detecting a temperature image or a smoke image by means of the sensor or a set of sensors, b) deciding if a fire is present or a normal situation occurs, c) if in the decision in b) a fire is registered, that the extinguishing agent supply is turned on, and d) on the basis of the location and the severity of that fire, one or more spray heads are actuated by means of the automated actuators connected to the valves of the spray heads.

A supervised fire suppression system (10, 100) is disclosed that includes a discharge valve (14, 114) for controlling release of a fire extinguishing agent from a container (12), a control head (16, 116) operatively associated with the discharge valve for actuating the discharge valve in the event of a fire, wherein the control head may be removed from the discharge valve to facilitate inspection of the control head, and an internal supervisory switching device (130) mounted within the control head and configured to interact with the discharge valve to provide an indication that the control head has been removed from the discharge valve.

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.

The invention relates to fire-fighting ground vehicles. A mobile fire extinguishing apparatus with pressurized foam generation comprises: a mixing chamber for supplying foam to a fire; and, a water supply system comprising a water supply pump with a drive, a foam-forming concentrate supply system comprising a foam pump with a drive, and also an air supply system comprising an air compressor with a drive. The drives of the compressor and of the foam pump are in the form of an adjustable hydraulic transmission of the air compressor drive and an adjustable hydraulic transmission of the foam pump drive, which are connected to a driving motor. The apparatus comprises a water meter, a gate valve having an electric drive, and a non-return valve, which are mounted on a water supply pipe between the water supply pump and the mixing chamber, and an electronic control unit for the gate valve.

A system for storing a hazardous product including a housing unit defining a product opening and a product door coupled to the housing unit adjacent to the product opening, wherein the product door is configured to form a seal with the housing unit about the product opening in response to a thermal event.

A containment system for a hazardous product includes a housing unit for storing the hazardous product. The housing unit includes sensors disposed throughout for detecting a thermal event. The system further includes an active fire suppression system configured to suppress the thermal event based on thermal event information received from the sensors. The system also includes a controller for processing signals from the sensors and activating the active fire suppression system, such as providing fire suppressants locally and/or globally or active venting. The system further includes a passive fire suppression system configured to suppress the thermal event using passive suppression without requiring activation from the controller, such as by coating surfaces of the system or using temperature sensitive venting or suppressant provision. The system may further include a training system to mimic the thermal event.

A system for storing a hazardous product including a housing unit having an interior volume and a door coupled to the housing unit configured to provide access to the interior volume. The system includes an electrical connection configured to transmit electricity into or out of the interior volume. The system further includes a ventilation system for directing gasses and heat produced during a thermal event out of the interior volume.
