Disclosed is a method of fire suppression, comprising: detecting with a sensor a fire stimulus in an environment surrounding the sensor; initiating a first discharge into the surrounding environment, wherein the first discharge comprises an inert gas, carbon dioxide, or any combination(s) thereof; and subsequent to initiating of the first discharge, initiating a second discharge into the surrounding environment, wherein the second discharge comprises a halocarbon.

An electric outlet fire detection and prevention system may comprise a temperature sensor and an electromagnetic interference (EMI) sensor. A processor within the system may monitor the measurements of the temperature and EMI sensors to determine that a fire has developed in an electric outlet box. The processor may then actuate a triggering mechanism in a cartridge containing fire extinguishing material such that the fire extinguishing material is dispersed in the outlet box. The fire extinguishing material may extinguish a developing fire and prevent the fire from spreading further. The processor may also be coupled with a server, which is configured to analyze measurements of the temperature and the EMI sensors and generate a building profile. When the server determines that any measurements deviate from the building profile, the server may instruct the processor to actuate the triggering mechanism and/or notify an electronic device associated with the building.

A system and method for providing inert gas to a protected space is disclosed. The system is onboard an aircraft that includes a pressurized cabin or cockpit space. The system includes an airflow path including an inlet and an outlet, and the inlet is in operative fluid communication with the pressurized cabin or cockpit space. A carbon dioxide separator is configured for separating carbon dioxide from air, and includes an inlet in operative fluid communication with the airflow path outlet, and a carbon dioxide outlet. The system also includes an inert gas flow path from the carbon dioxide outlet to the protected space.

The present invention is directed to a fire extinguisher having a built-in module for providing auditory instructions on how to use the fire extinguisher properly in an emergency situation. The present invention features a fire extinguisher comprising a chamber for holding extinguishing chemicals and a cap screwably attached to the chamber. The cap may comprise a release valve, a handle for activating the release valve, a safety pin for preventing activation of the handle before safety pin removal, a nozzle for directing extinguishing chemicals, and a pressure gauge. The fire extinguisher may further comprise an instructional module disposed in the cap for relaying audio instructions through a speaker. The speaker may be actuated by an activation mechanism disposed on the cap.

The invention relates to a multi-area fire extinguishing system, having a control system, a number of fluid control lines that are configured to transmit a control pressure as a function of control commands of the control system, and a number of fluid-actuated area valves that are each in fluid communication with the control lines, wherein the area valves are configured to be actuated as a function of the received control commands. The invention proposes, in particular, a fluid-actuated area blocking apparatus which is operatively coupled to the fluid control lines and to the area valves and which is configured such that, when one or more area valves are actuated, said area blocking apparatus opens up those area valves and blocks all other area valves. The invention furthermore relates to a controller for a multi-area fire extinguishing system, to an area blocking apparatus for a fire extinguishing system, and to the use of same.

An aircraft including a fuselage defining a cabin and baggage bay, engine compartments for receiving engines, an auxiliary power unit compartment for receiving an auxiliary power unit, and a fire suppression system including first and second reservoirs containing a fire suppressant. The reservoirs are each connected to all of the engine compartments for distribution of the fire suppressant thereto. The first reservoir is connected to only one of the auxiliary power unit compartment and baggage bay, and the second reservoir is connected to only the other of the auxiliary power unit compartment and baggage bay. A fire suppression system for an aircraft and a method of connecting a fire suppression system of an aircraft are also discussed.
