A battery pack includes a plurality of battery modules respectively having at least one battery cell, a rack case configured to accommodate the plurality of battery modules, a fire distinguishing water supply unit disposed at the rear of the rack case and connected to the plurality of battery modules, and a bracket unit configured to cover the fire distinguishing water supply unit and disposed at the rear of the rack case.

A sensor unit for a fire suppression system includes a sensor module, a display module, a controller, and an antenna. The sensor module includes a first housing including a fitting configured to be coupled to a tank containing a fluid, a pressure sensor located within the first housing and configured to sense a pressure of a fluid and provide pressure data related to the pressure of the fluid, and a temperature sensor located within the first housing and configured to sense a temperature and provide temperature data related to the temperature of the fluid. The display module includes a second housing selectively attached to the first housing such that the display module is selectively removable from the display module, and a user interface. The controller is operatively coupled to the pressure and temperature sensors. The antenna is configured to transfer the pressure data and the temperature data to a network.

A fire suppression system having a first triggering mechanism capable of being remotely triggered in response to a fire condition and a second manual triggering mechanism. More particularly, the fire extinguisher includes a valve for a fire extinguisher capable of manual and automatic operation. The system further includes a mechanism to notify of inoperable local status. During automatic operation, the system can be being triggered by a control panel in electrical communication, such as in response to a signal from smoke detectors. This system may also be manually triggered or in response to a temperature threshold sensor or other sensors. The valve includes an actuator that provides a separate area to place a safety pin for storing securely, and which provides feedback to the control system that the safety pin is properly stored and therefore, the fire extinguisher is active.

A fire-fighting system for an aircraft, the fire-fighting system having a reservoir having an exterior envelope which delimits an interior volume of the reservoir and an interior wall which extends inside the exterior envelope and separates the interior volume into a first chamber and a second chamber which are separate from one another and are each filled with an extinguishing fluid. A network of pipes, and a valve system are provided which are arranged so as to allow, in succession, the extinguishing fluid to flow from the first chamber to the network of pipes, and then the extinguishing fluid to flow from the second chamber to the network of pipes. Such a fire-fighting system allows simpler installation in the aircraft, the fitting of a single network of pipes and hence a saving in terms of weight and volume.

A battery module includes a cell stack including a plurality of battery cells stacked in a direction, a module housing having an internal space in which the cell stack is received and an air inlet and an air outlet through which air enters and exits, a valve installation hole formed through a side wall of the module housing, a feed valve nozzle installed at the valve installation hole facing the internal space of the module housing, and a water expandable member provided in the module housing. The water expandable member expands in volume when it absorbs water during operation of the feed valve nozzle to close at least one of the air inlet, the air outlet or the valve installation hole.

A building sheltering structure is configured to facilitate the shielding of domicile or building into an underground foundation before an emergency environmental condition arises. The foundation includes a cover plate and/or a second plate that translate horizontally to occlude the at least one domicile upon retraction into a secure cavity of the foundation by a lift assembly in the foundation cavity. The cover plate and second plate offer optimal protection to the domicile thereunder for various extreme conditions. Mounted atop the lift assembly, the at least one domicile can be fully retracted into the foundation cavity and completely shielded. The operation of the lift assembly is commanded and powered by a supply system, of which a processor facilitates emergency warnings and panic transmissions to signal for help. Further, a plurality of solar panels mounted atop the at least one domicile keeps the system charged for the use in emergency.
