The present invention provides a fire suppressant system for vehicles and method for preventing fire outbreak within a vehicle's fuel tank or expulsion thereof.

A heat-activated fire-suppression system is provided. The system can include one or modules installed in an exterior panel of a building. The one or more modules can include a shape memory alloy wire that deforms upon heating to cause the module to release a pressurized substance. The system can include an alarm module that emits an auditory alarm. The system can include a fire-suppression module that releases a fire-suppressing substance upon the shape memory wire deforming in response to heating.

An extinguishing device for an electrical unit on an aircraft cabin monument or in an aircraft structure cavity, a combination of a holder and an extinguishing device and systems formed by extinguishing devices and a control unit and by combinations of an extinguishing device and a holder and a control unit. The extinguishing device has a base element for a holder. An extinguishing agent container has a casing and holds an extinguishing agent. A triggering device is connected to the extinguishing agent container to act in response to receiving a triggering signal wherein an extinguishing agent is released into the extinguishing device surrounding area. A data transmission device has a data store with an identifier unique to the extinguishing device and connected to the triggering device, the data transmission device for sending a warning signal via a network to a control unit in response to the triggering device receiving the triggering signal.

A fire suppression system has a tank unit (40, 42, 44, 46). A tank body has a first port and an interior for storing at least one of fire suppressant and driver gas. A discharge assembly is mounted to the first port and has a discharge valve (50, 52) and a first monitoring switch or sensor (230 240) having a normally closed output (532) and a normally open output (534). A first monitoring system (100) is coupled to one of the normally closed output and the normally open output. A second monitoring system (340) is coupled to the other of the normally closed output and the normally open output.

According to an aspect, a fire suppressant system includes a first fire bottle in operable communication with a first cockpit control switch via a first channel, and a first sensor-based switch via a second channel. Additionally, the fire suppressant system includes a second fire bottle in operable communication with a second cockpit control switch via a third channel, and a second sensor-based switch via a fourth channel.

The present invention provides a fire extinguishing system capable of reliably carrying out initial fire fighting using a limited fire extinguisher even if a protected area is wide for example. A control unit 20 of the fire extinguishing system of the invention includes an ignition point judging unit 21 for judging an ignition point from heat source information, a fire determining unit 22 for determining whether a fire breaks out from the heat source information, an ejecting unit selecting unit 23 for selecting one or some of fire extinguisher ejecting units 2 which eject the fire extinguisher by the ignition point judged by the ignition point judging unit 21 when the fire determining unit 22 determines that the fire breaks out, an operation direction calculating unit 24 for calculating an operation direction of an ejecting unit driving unit 3 corresponding to the fire extinguisher ejecting unit 2 selected by the ejecting unit selecting unit 23, and an output unit 25 for outputting, to the ejecting unit driving unit 3, driving instructions of the operation direction calculated by the operation direction calculating unit 24 and outputting ejection instructions to the fire extinguisher ejecting unit 2 selected by the ejecting unit selecting unit 23.

An example apparatus includes a cabinet body and a first storage receptacle at the cabinet body. The first storage receptacle is to temporarily store an electronic device. The apparatus further includes a second storage receptacle at the cabinet body. The second storage receptacle is to temporarily store another electronic device. The second storage receptacle is separate from the first storage receptacle to prevent physical access to the first storage receptacle through the second storage receptacle. The apparatus further includes a fire suppression mechanism to independently suppress a fire in the first storage receptacle or a fire in the second storage receptacle.
