An automatic fire containment system is disclosed, together with certain components which may be used therewith. An embodiment of the system attempts to provide fire suppressant to regions surrounding a fire zone, thus containing the fire within limited area, but not flooding a larger area than necessary to contain the fire. Sprinklers which may be selectively automatically activated electrically, optionally in addition to common heat triggering, are also provided. Sensors may be embedded in the sprinklers. Further provided are sprinkler capable of reporting activation thereof via electrical state change. Further provided are devices to reduce installation costs and increase the resolution of firefighting and/or fire containment systems by providing wireless communications between network nodes such as flow switches, valve status switch, and individual sensors, sprinkler, and other ports, and a control panel/controller.

A fire extinguishing apparatus having a fire prediction function. The fire extinguishing apparatus includes: a fire extinguishing tube container having a fire extinguishing material therein, and automatically emitting the fire extinguishing material when being exposed to surrounding fire or heat; a fire pre-sensor coupled to one side of the fire extinguishing tube container and sensing surrounding presymptoms of a fire by measuring internal pressure of the fire extinguishing tube container; and a fire monitor connected to the fire pre-sensor and generating monitoring information while collecting internal state information and external environmental information of the fire extinguishing tube container. Therefore, the fire extinguishing apparatus can measure the internal pressure of the tube container for fire extinguishing, so as to predict and detect the occurrence of a nearby fire, and provide a notification to the outside through a network, so as to perform fire-related predictive maintenance and initial response.

An advance pneumatic detector to indicate pressure changes in an environment includes a switch, a pressure tube, an endcap, a piston, and a magnet. The pressure tube is connected to the switch. The endcap is disposed on an end of the pressure tube opposite from the switch. The piston is disposed within and forms a seal against the pressure tube. The piston is slidably engaged with the pressure tube. The magnet is slidably attached to and surrounds a portion of the pressure tube. The magnet is configured to control the positioning of the piston within the pressure tube.

A pneumatic sensing apparatus for use in an overheat or fire alarm system includes a sensor tube containing a pressurized gas in communication with a pressure sensor configured to sense a temperature variation based on changes of the pressurized gas. A pressure switch is coupled to the pressure sensor. The pressure switch includes a signal transducer configured to provide an output indicative of an overheat or fire alarm condition.

Devices and methods are disclosed for monitoring at fishing vessels to detect blast fishing activity. A blast sensor is mountable to a vessel such that it produces a signal in response to pressure waves in water. A controller receives the signal and is operable to analyze the signal to detect blast events based on signal characteristics. A position measurement device measures a position of the vessel. A transmitter is provided to wirelessly transmit status information including a unique identifier of the monitoring unit and indicative of the position of the monitoring unit and to send a wireless alarm signal in response to a detected blast event.

The conceived invention simplifies current art methods of incorporating fire notification appliances with fire sprinkler systems by replacing vane and pressure type of waterflow switches with a single water driven generator having dual functionality. It includes power generation and activation when water moves through a sprinkler system. A notification appliance may use audible, visible, or other stimuli to alert the occupants of a fire. The system also includes a waterflow switch output to trigger an external fire/security alarm system when required and a digital controller with a delay timer to prevent false alarms due to water pressure fluctuations. Another embodiment includes both alarm monitoring and circuit supervision to enhance operation and system maintenance.
