One or more systems and/or methods are disclosed for a nozzle with wire connection to a hose, which may allow wired communication between the nozzle and a distant control center. A hose connector with one or more locating pins may be used for easy alignment and quick establishment of electrical connection between the nozzle and the hose. The nozzle may comprise a swiveling joint configured to fully swivel while maintaining electrical connection between the hose connector and an electronic housing. A slip ring assembly may be used in the swiveling joint to maintain the electrical connection.

A method of suppressing a kitchen fire includes detecting a fire and identifying a location of the fire with a tracking system, aiming a nozzle at the location, and releasing an agent through the nozzle at the location.

An improved nozzle for use with a fire hose having an infra-red temperature sensor that is aligned with an output of the nozzle. The sensor will detect the infrared energy produced by a fire hot spot and provide a visual indication of the energy on a display. The temperature sensor operates a thermometer and is placed in the center of the discharge nozzle allowing water to pass around the sensor. A laser is positioned next to the sensor on the outlet of the nozzle to project a high intensity visible light toward the area that the IR sensor is directed.

An extinguishing-agent discharge device includes a casing having a guide channel for an extinguishing agent, a metallic handle, a hose connection, an adjustment means for regulating an extinguishing-agent supply using a manual control unit and a discharge nozzle. A measuring-current transformer generates a current signal proportional to the electric current flowing in the extinguishing agent; an insulator section divides the casing into a discharge area having the discharge nozzle and an inlet area having the manual control unit, the measuring-current transformer disposed in the insulator section; a first electrode disposed in the discharge area in the extinguishing-agent flow and serves for detecting an extinguishing-agent potential; a second electrode disposed at the handle for detecting a ground potential in the inlet area; and a controller for evaluating the current signal for a potential difference occurring between the extinguishing-agent and ground and having a drive element acting on the adjustment means.

The present invention relates to a discharge pressure adjustment cartridge that is combined with a fire hose pressure relief valve and, more particularly, to a discharge pressure adjustment cartridge that is combined with a fire hose pressure relief valve, the discharge pressure adjustment cartridge enabling a firefighter to easily control the discharge direction of firefighting water by removing upward force that is generated in the firefighting water in the opposite direction to gravity by discharge pressure.

An extension assembly for a fire suppression spray nozzle is provided. A tube having a first end and a second end is welded to a female hose coupler at the tube's first end. A male hose coupler is welded to the second end of the tube. A support sleeve connected to the female hose coupler inserts into a fire suppression spray nozzle or another instance of the extension assembly to provide for easy alignment of the threaded connectors and for adding strength to the connection.

In embodiments, an adjustable nozzle includes a nozzle body having an inlet section with an inlet opening, an outlet section with an outlet opening, and a fluid flow path extending from the inlet opening to the outlet opening; an adjustable spray restrictor segment located in the outlet section; and an actuator that displaces the adjustable spray restrictor segment toward and away from a center of the fluid flow path, thereby varying an effective width of the outlet opening to vary a pattern of fluid flowing from the fluid flow path through the outlet opening.
