A fire extinguishing or fire prevention device comprises an extinguishing agent conduit arrangement. The extinguishing agent conduit arrangement comprises a plurality of longitudinal conduit elements each adapted to conduct a fire extinguishing agent therethrough, and a plurality of transverse conduit elements each adapted to conduct a fire extinguishing agent therethrough. Each of the longitudinal conduit elements is connected to one of the transverse conduit elements by at least one connecting element, the connecting elements each being suitable for further conducting the fire extinguishing agent from a longitudinal conduit element into a transverse conduit element or from a transverse conduit element into a longitudinal conduit element. Further, the fire extinguishing or fire prevention device comprises at least one extinguishing agent supply line; which is arranged at the extinguishing agent conduit arrangement and adapted to provide the fire extinguishing agent into at least one of the longitudinal conduit elements or the transverse conduit elements. Further, the fire extinguishing or fire prevention device comprises a plurality of outlets disposed on the extinguishing agent conduit arrangement and adapted to discharge the fire extinguishing agent from the extinguishing agent conduit arrangement. At least one flight-capable carrier device is disposed on the extinguishing agent conduit arrangement and adapted to lift and at least temporarily keep the extinguishing agent conduit arrangement with the outlets and at least a part of the fire extinguishing agent supply line in a distance from the ground surface. The extinguishing agent supply line of the fire extinguishing or fire prevention device is connected to an extinguishing agent reservoir adapted to provide the fire extinguishing agent to the extinguishing agent conduit arrangement while the extinguishing agent conduit arrangement is lifted or kept by the at least one flight-capable carrier device.

A fire suppression system includes an inert gas source to supply inert gas to an enclosure via distribution piping. The system includes a fire suppression nozzle that is installed in the enclosure. The nozzle includes an inlet that connects to the distribution piping and includes a plurality of outlet holes. During discharge of the inert gas, the sound power level from, the nozzle is no greater than 125 dB for a frequency range from 500 to 10,000 Hz for a coverage area up to 32 ft.×32 ft. in compliance with UL 2127. The nozzles disclosed herein are configured such that gas exiting a plurality of outlet holes is balanced.

A fire suppression system including an extinguisher assembly, a trigger assembly and a communication assembly is disclosed. The extinguisher assembly including a fire extinguisher having a fire retardant within. The fire extinguisher including a plurality of nozzles aimed in various direction for dispersing the fire retardant in multiple directions. The trigger assembly being atop of the fire extinguisher. A lever included within the trigger assembly to actuate the trigger when needed. The lever suspended above of the trigger by a melting pillar. The melting pillar melting when temperatures from a fire within the appliance reach a predetermined threshold to allow said lever to engage the trigger from above. Thereby causing the fire retardant to be dispersed in multiple directions by the plurality of nozzles to extinguish the fire. This helps to protect users from costly repairs and potentially dying within the fire.

A nozzle for a fire suppression system includes a smooth dome having an exterior surface approximating a partial sphere, a cavity within the dome, and a plurality of orifices through the dome providing fluid communication between the cavity and the exterior of the dome. A fire suppression system is also disclosed.

A modular fluid spray nozzle is constructed from an inner conduit, having a sidewall with a center hole, housed inside a center conduit that includes a window defined by a sidewall, and a flexible or rigid outer conduit wrapped around the center conduit and forming a chamber with the rectangular window. The chamber is in fluid communication with the center hole and with at least two apertures defined by the outer conduit. The inner conduit is configured to be coupled to any type of conduit material, such as PVC pipe or another modular fluid hose segment.

A floor nozzle assembly and systems and methods thereof for delivering a fire suppressant foam to a protected area. The nozzle assembly has a body and deflector in contact with one another to form a plurality of passageways through which a fire suppressant flows. The deflector has a deflector flange and a plurality of projecting members in contact with the body to form the passageways. The nozzle assembly has one or more of the following: i) a radial outer portion at each projecting member having a plurality of curved edges with at least two different curvatures; ii) each passageway is formed by parallel planar sidewalls; iii) the projecting members extend radially over a majority radial length of the deflector flange; and/or iv) the deflector flange has, with respect to a horizontal, a surface at an angle that is less than a support surface of the nozzle body.
