Described herein are zonal fire suppression systems and methods of using such systems for suppressing fires in cargo aircraft. A system is configured to individually monitor the temperature in each of multiple cargo zones in the cargo area. The system is also configured to selectively activate one or more of multiple zone distribution components to distribute a fire suppressant material, based at least on the temperature monitoring. The zonal approach to the temperature monitoring and to the fire suppressant material distribution allows reducing the fire suppressant material amount needed on the cargo aircraft, which, in turn, reduces the aircraft load. Furthermore, in some examples, the zonal approach eliminates unnecessary contact between the cargo (e.g., in the zones unaffected by fire) and the fire suppressant material. In some examples, this fire suppression involves depressurizing of the cargo area, in addition to or instead of the fire suppressant material distribution material.

An air maintenance device (AMD) for fire protection system includes a gas inlet configured to couple with a source of compressed gas; a gas outlet configured to couple with a pipe network of the fire protection system; a first sensor configured to sense a system parameter of the pipe network of the fire protection system and to produce a first output corresponding to the system parameter; a first gas flow valve in fluid communication with and between the inlet and the outlet; and a first control circuit in communication with the sensor and with the first gas flow valve. The first gas flow valve is electrically controlled and configured to control a flow of gas from the source of compressed gas into the pipe network. The control circuit is configured to receive the first output from the sensor and output a control signal that is a function of the system parameter to the first gas flow valve. Other example AMDs, systems including AMDs, methods of installing AMDs, and methods of suppling gas to a pipe network using an AMD are also disclosed.

A control system for use with a fire-fighting device includes a remote component having a touch sensitive screen configured to receive a user-requested parameter of fluid and to display a plurality of indicators associated with the fire-fighting device. The control system also includes a base component including a programmable logic controller having predefined logic stored thereon. The base component automatically controls operation of the pump based on the predefined logic and the user-requested parameter of fluid. The remote component receives signals from the base component and presents, via the touch sensitive screen, at least one of a first of the plurality of indicators indicative of a water volume associated with a first water source stored at a fire fighting device, and a second of the plurality of indicators indicative of a water pressure associated with a second water source remote from the fire-fighting device.

The present invention relates to a thermal management system and a thermal management method for cooling a heat-generating electronic device such as a battery and for extinguishing a fire occurring in the heat-generating electronic device. More particularly, the present invention relates to a thermal management system and a thermal management method that are capable of cooling a heat-generating electronic device such as a battery of an energy storage system (ESS) in various ways at multiple stages and of extinguishing a fire in the heat-generating electronic device. The present invention has an effect of preventing fire by cooling a heating-generating element such as a battery of an energy storage device. In addition, the present invention has an effect of stopping a cooling operation and starting a fire extinguishing operation when a fire occurs during the cooling operation.

A firefighting apparatus includes a reaction chamber, a CO.sub.2 tank fluidly connected to the reaction chamber, acid and carbonate tanks, acid and carbonate pumps, and a controller. The acid and carbonate pumps act to correspondingly regulate flow of acid from the acid tank and carbonate from the carbonate tank to the reaction chamber. Acid and carbonate react within the reaction chamber to produce CO.sub.2 gas which flows into the CO.sub.2 tank and liquid byproduct which is releasable through a reaction chamber outlet. A CO.sub.2 gas delivery valve is fluidly connected to a delivery outlet of the CO.sub.2 tank to regulate release of CO.sub.2 therefrom. The CO.sub.2 tank includes a pressure sensor for measuring a CO.sub.2 tank pressure. The controller is configured to control operation of the acid and carbonate pumps, and the CO.sub.2 gas delivery valve according to a user command signal, the CO.sub.2 tank pressure, or both.
