A system and a method for controlling temperature in different zones of a premises. A method includes receiving a measurement of temperature sensed by a first fire detector positioned at a first zone of a premises. The method further includes receiving a measurement of temperature sensed by a second fire detector positioned at a second zone of the premises. The method also includes controlling the temperature by a thermostat in the first zone based on the measurement of the sensed temperature received from the first fire detector and in the second zone based on the measurement of the sensed temperature received from the second fire detector.

The invention comprises a fire extinguisher and method, wherein the fire extinguisher has a sealable high-pressure container that forms a hollow interior connected by a valve to an environment external to the said container. The said container holds at a high pressure at room temperature a composition of liquid carbon dioxide and a non-hydrate, hydrophobic, cyclic organo-siloxane compound, the said compound further having a freezing point of at least −20° C. at one atmosphere. Upon release of the combination to the environment external to the container, the compound further produces a clathrate. In at least one embodiment of the invention, both the clathrate and the non-hydrate, hydrophobic, cyclic organo-siloxane compound have firefighting conductive properties.

An apparatus, operations controller and methods for controlling unmanned aerial vehicles for detection, prevention and suppression of fires in a designated zone are presented. Monitored information is received and analyzed to detect a presence of a fire event or a fire risk in the designated zone. A cargo unmanned aerial vehicle is directed to a vicinity of the fire event or the fire risk and instructed to deploy a fire retardant or a fire suppressant at a location of the fire event or the fire risk, if the presence of the fire event or the fire risk is detected.

A method is described for using cellular glass blocks, cellular glass nodules, hollow glass spheres, or other buoyant glass materials to attenuate oil fire, limit thermal radiation from an oil fire, and reduce the risk of boil-over phenomenon. Cellular glass blocks, cellular glass nodules, hollow glass spheres, or other buoyant glass products may be deployed passively, prior to an ignition event, or actively, as a response to an ignition event to provide control. Cellular glass or other buoyant glass materials may be in any physical shape such as block, sheet, aggregate, or nodule.

A liquid projection bomb includes a shell and is characterized in that functional liquid is filled into the shell, and the shell is made of a soft or hard material easy to crack when bumped. The functional liquid includes water, alcohol, fuel oil, and a solution of water mixed with an extinguishing agent, a fertilizer or a drug.

According to one aspect, a fire extinguisher includes a fire extinguisher reservoir and a fire extinguisher outlet burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent within the fire extinguisher reservoir. The fire extinguisher actuator assembly includes a cutter positioned within the fire extinguisher proximate the fire extinguisher outlet burst disc. The fire extinguisher actuator assembly also includes a motorized activation device having a drive shaft. The motorized activation device is operable to rotate the drive shaft and push the cutter to pierce the fire extinguisher outlet burst disc, thereby releasing the pressurized fire extinguishing agent through the discharge head.

A device for limiting consequences of a fire, in a room, including a reservoir including a vessel containing a liquid, the reservoir including one or more chambers in communication with a storage cell and one or more other chambers. The reservoir also includes at least a first overflow tank and at least a second overflow tank, both integral, placed on either side of the reservoir, each tank configured to receive the liquid when the liquid exceeds a predetermined given height in the vessel.
