A control system for use with a fire-fighting device includes a remote component having a touch sensitive screen configured to receive a user-requested parameter of fluid and to display a plurality of indicators associated with the fire-fighting device. The control system also includes a base component including a programmable logic controller having predefined logic stored thereon. The base component automatically controls operation of the pump based on the predefined logic and the user-requested parameter of fluid. The remote component receives signals from the base component and presents, via the touch sensitive screen, at least one of a first of the plurality of indicators indicative of a water volume associated with a first water source stored at a fire fighting device, and a second of the plurality of indicators indicative of a water pressure associated with a second water source remote from the fire-fighting device.

A remotely controllable wireless camera system that may be mounted on an emergency worker or on the emergency worker's helmet. The system includes a digital camera and an infrared camera. The system is connected to a network and live-streams video via the network and a server in real-time.

A content-driven and content delivery UAV system. The UAV system includes a content source to provided pressurized content to the UAVs via a content transmission media. The pressurized content is utilized to drive a mechanical propulsion and steering system to keep the UAV aloft and direct it to a particular location. The pressurized content received by the UAVs can be directed back to the content source, to another UAV and or discharged from the UAV to a desired target. Thus, the UAVs may include a nozzle or valve for discharging the content and thus delivering the content to a desire location.

In one implementation, a computer-implemented method includes receiving, at a computer system, information that indicates that a fire has been detected in a building and that a fire suppression system within the building has begun dousing the fire; monitoring sensor information from one or more sensors located within the building; determining, by the computer system and based on the sensor information, whether the fire has been extinguished; activating, in response to determining that the fire has been extinguished, a feature to turn off a water supply to the building, the feature being presented on a computing device for a user who is associated with the building; receiving, after activating the feature and from the computing device, a command to turn off the water supply; and transmitting, by the computer system, a control signal that causes an electromechanical device to close a water valve within the building.

A firefighting monitor that has a first section, a second section joined to the first section by a first pivot connection, and a plurality of ball bearings positioned in the first pivot connection between a pair of bearing seats. Wherein, the bearing seats define an arc of contact with each of the plurality of ball bearings, the center of the arc of contact defining a tangent angled with respect to a flow axis defined by the first pivot connection.

The invention relates to a control system (10) of a fire-extinguishing installation, having at least one control line (11) for controlling a controlling procedure of the fire-extinguishing installation, wherein the control line (11) in a passive operation is unpressurized and the control line (11) in a control operation is impinged with a control pressure, and a safety device (12), fluidically connected to the control line (11), having a pressure equalization chamber (13) in which a holding element (3) and a movable closure element (2) are disposed. It is proposed that the closure element (2) is disposed in the pressure equalization chamber (13) so as to be displaceable between a first terminal position and a second terminal position, and the holding element (3) is configured for exerting on the closure element (2) a restoring force in the direction of the first terminal position, wherein the restoring force on the closure element (2) in the second terminal position of the closure element (2) is higher than the weight force of the closure element (2), and in the first terminal position of the closure element (2) is lower than a pressure force that in the control operation acts as a function of the control pressure on the closure element (2).
