The invention concerns a fire extinguishing system valve (1) comprising a housing (2), a fluid inlet chamber (11) in the housing (2), a fluid outlet chamber (13) in the housing (2), and a closing body (9) reciprocable between a blocking state and a release state and which in the blocking state prevents a direct flow of fluid between the fluid inlet chamber (11) and the fluid outlet chamber (13) and in the release state connects the fluid inlet chamber (11) directly in fluid-conducting relationship to the fluid outlet chamber (13). According to the invention the fire extinguishing system valve (1) has at least one manometer (15, 17) which is operatively connected to the fluid inlet chamber (11) or the fluid outlet chamber (13) and which is mounted to the housing (2), and a venting device (21) integrated into the housing (2) for the at least one manometer (15, 17).

The invention concerns a dry alarm valve station of a fire extinguishing installation. According to the invention it is proposed that the dry alarm valve station includes an alarm valve, an alarm line connected to the alarm valve, an alarm alert device, preferably with an alarm pressure switch, which is connected to the alarm line and is configured to trigger an alarm signal when there is a predetermined fluid pressure in the alarm line, and a pressure-operated valve which is interposed between the alarm alert device and the alarm valve, is controlled by a control chamber, and is configured to block the alarm line as long as there is the predetermined control pressure in the control chamber and to open it when the pressure falls below the predetermined control pressure in the control chamber.

A monitoring and testing system which is designed to automatically seal off the system from its gas supply and monitor internal pressure during that time to perform regulatory testing. The scheduling can be automated and can be done without maintenance personnel having to monitor the time passage and pressure manually. The system may also be designed to monitor operation of the air compressor, or related gas supply device, and evaluate if the operation of the gas supply is operating in a fashion indicative of a larger than desired leak. This effectively allows the system to monitor pressure changes during regular operation and on a somewhat continuous basis.

An example system for suppressing a fire condition in an aircraft includes a supply of fire suppressant agent on-board the aircraft, a conduit coupled to the supply of fire suppressant agent and configured to carry fire suppression agent, an inlet located downstream of the conduit that is coupled to the conduit and is configured to be attached to a cargo container in the aircraft to deliver the fire suppression agent directly into the cargo container, a valve connected to the conduit between the supply of fire suppressant agent and the inlet, a detector located inside the cargo container, and a computer controller in communication with the valve and in communication with the detector, and controlling operation of the valve for delivery of the fire suppression agent into the cargo container based on an output received from the detector.

A wide-area wildfire suppression system uses a network of geographically distributed water sprayers, and includes at least one wind sensor and a fire-suppression controller communicatively coupled to the water sprayers and the at least one wind sensor. The at least one wind sensor detects wind direction and communicates wind-direction information to the fire-suppression controller, which uses the wind-direction information to activate at least one of the water sprayers upwind of an asset or area to be protected. Parameters of the water spray, such as flow rate, droplet size, spray pattern, spray direction, spray elevation, or aeration, can be adapted based on wind direction or wind speed,

Methods and systems for sprinkler system (100) diagnostics are provided. Aspects include increasing, by a controller (115), a fluid pressure in a pipe (14) to a first pressure, wherein the pipe (14) is coupled to at least one sprinkler (40), receiving, from a sensor (50), first sensor data associated with a moving portion (210) of the least one sprinkler (40), wherein the first sensor data includes a first movement distance (250) of the moving portion (210) of the at least one sprinkler (40), and enacting a first action based at least in part on the first movement distance (250) being less than a threshold.
