A relatively small fire apparatus vehicle, which may have a single rear axle, is provided that includes a high-flow articulated water tower that delivers water at a rate of up to 1500 GPM (gallons per minute). The fire apparatus vehicle may include a turret support arrangement with a torque box that is supported from the vehicle chassis and that supports a turret at its turret base. A pair of outriggers is connected to at least two of the vehicle chassis, the torque box, and the turret base through a pair of outrigger mounts on opposite sides of the vehicle chassis.

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.

The present invention relates to a method for producing compressed-air foam and to a corresponding device. The method comprises providing fire-fighting water admixed with foaming agent, and foaming the fire-fighting water admixed with foaming agent, with addition of compressed gas, wherein the compressed gas comprises a chemical extinguishing agent. The method according to the invention and the device according to the invention allow the production of an effective extinguishing foam due to the inhibitory effect of the chemical extinguishing agent.

A low pressure water mist nozzle for active fire protection from water supplied with supply water pressures of 0.5 bar to 20 bars, characterized by having a separation wall (3) with multiple openings (4) of sizes 01 mm to 02, 5 mm in angles of 10 to 50 to the wall surfaces, which are followed by a cavity (8) having a centrally located outlet opening (6) in its end wall, which are located opposite the separation wall (3) containing multiple openings (4).

An aircraft that can fly stably when water is discharged from a hose installed on the airframe, and an aircraft system, are provided. The aircraft system can include a master aircraft, slave aircrafts and a remote control device. The aircraft preferably fly as a unit. Each slave aircraft can include four rotary blade portions having propellers, and a suspending means for suspending a part of a hose. The master aircraft may include four first rotary blade portions having first propellers arranged to rotate in a horizontal plane, four second rotary blade portions having second propellers arranged to rotate in a vertical plane, and a nozzle on which a tip end part of the hose is installed. The direction of the center axis of the nozzle is parallel to the direction of the rotational axes of the second propellers.

A high pressure monitor includes an outlet body with a transverse passage, which extends through the body to form two inlets of the outlet body, and a second passage, which is in communication with the transverse passage and extends through the outlet body to form an outlet. The monitor further includes first and second bodies, with the outlet body mounted between the first and second bodies. Each of the first and second bodies has a transverse passage, which are in fluid communication with the inlets of the outlet body. A first swivel joint is provided between the outlet body and the first body. A second swivel joint is provided between the outlet body and the second body. Further, each of the swivel joints comprises a pressure balanced hydraulic fitting with seals and bearings, wherein the seals and bearings are oriented to reduce the axial pressure on the bearings from fluid flowing through the monitor.

A system for monitoring smoke and/or temperature of an electronic device includes a fiber harness having at least one fiber optic cable terminating at a node. The node is located to measure one or more conditions at the electronic device, and a control system operably connected to the fiber harness. The control system includes a light source configured to transmit light through the fiber harness, a light sensitive device configured to receive scattered light associated with the node, and a control unit configured to analyze the scattered light to determine at least one of a presence and magnitude of the one or more conditions at the node of one or more conditions at the electronic device, wherein the control unit is further configured to transmit a signal in response to the one or more conditions, wherein the one or more conditions are one or more of smoke, fire, and temperature.
