A water mist nozzle (2) for a fire suppression system comprises a nozzle head (4) including a discharge nozzle (6) for supplying a fluid jet (12); a support structure (8); and a stationary deflector element (10). The stationary deflector element (10) is fastened to the support structure (8) and comprises a body with a substantially round outer periphery having a base portion (28) and a substantially conical upper portion (22) with a central peak (24). The substantially conical upper portion (22) provides a plurality of flowpaths (26), the flowpaths (26) extending substantially radially from a radial position close to the central peak (24) in a direction towards the outer periphery, the flowpaths (26) having at least one portion (26a, 26b, 26c) of decreasing slope, in which the slope of the bottom of the flowpaths (26) decreases along the flow direction towards the outer periphery. The stationary deflector element (10) is fastened to the support structure (8) such that the central peak (24) of the substantially conical upper portion (22) of the stationary deflector element (10) faces the discharge nozzle (6) and that the fluid jet (12) exiting the discharge nozzle (6) impinges onto the central peak (24) and is distributed to the environment, substantially in a lateral direction, through the plurality of flowpaths (26).

A spray module for a device for fighting a vegetation fire, the spray module includes: an inlet for a fluid, an outlet for the fluid, a fastening unit for fastening the spray module in a raised position with respect to an underlying surface, a first spray mist nozzle having a first opening area, which is configured to dispense a first spray mist, and a second spray mist nozzle having a second opening area, which is configured to dispense a second spray mist, the first opening area and the second opening area are arranged parallel to one another on the spray module in such a way that the first spray mist and the second spray mist can be dispensed in two opposite directions.

Fire protection systems and methods of fire protection systems for protection of a stored commodity. The systems and methods included a plurality of fluid distribution devices disposed above the stored commodity and configured for selective identification and controlled actuation in response to a fire. The systems have a hydraulic demand defined by at least one of: i) a hydraulic design area having a minimum operational area of less than 768 square feet; or ii) less than twelve hydraulic design devices.

A battery pack frame comprising includes a space configured to accommodate at least one battery pack. The at least one battery pack is used for a predetermined period of time or below a predetermined capacity. A height of the battery pack frame is greater than a height of the at least one battery pack.

A robot for detecting and saving a life, includes: a body part including a plurality of unit joints; a head part which is provided at the front of the body part in the direction in which the body part moves forward, and which has a gripper capable of picking up an object by a plurality of tongs parts that are folded and unfolded; and an extension part capable of extending forward from the head part so as to enter a small space that is difficult for the body part to enter.

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.

A wall-mountable spray head unit (ii) is described. The spray head unit comprises a rotatable spray head assembly (8) which comprises a spray manifold (18) rotatable about a first axis (17), a spray nozzle (19) supported by the spray manifold and orientated to deliver a mist of fire-suppressant material radially in a plane in a plane defined by the first axis and a second axis which is perpendicular to the first axis. The spray head unit includes a sensor (20) and/or an interface (35) for receiving a sensor signal from an external sensor and/or a control signal from an external controller. The rotatable spray head assembly does not support a sensor.
