Disclosed is a system for controlling fire in a first area, the system having: a plurality of implements including a source of pressurized fluid and a smoke detector which is an aspirating smoke detector, the fluid source being in a second area and a conduit fluidly connecting the fluid source to the first area, and the smoke detector in a third area, the smoke detector fluidly connected to the conduit for detecting smoke in the first area.

Provided is a fire-fighting system that has a very simple structure with only a hose and a water discharge nozzle mounted on a vehicle, can bring the vehicle close to the fire site by automatic operation or remote control, and minimizes the occurrence of a water hammer when water is supplied. A hose reel is installed on a base which is installed on a vehicle, so as to be rotatable around a rotary shaft extending vertically, a hose having shape retaining property is spirally wound around the hose reel and around the rotary shaft, the lower end of the hose is connectable to a water discharge pump installed behind the vehicle, and the upper end of the hose passes through the rotary shaft of the hose reel and is connected to a water discharge nozzle installed at the upper position of the vehicle.

Provided herein are a fire suppression device or control device for putting out a fire using a high pressure water and air-line to propel and diffuse the water as a mist towards the flames. The device has a cylindrical pipe with a diffuser nozzle on one end, a Y-connector on the other end, shutoff valves that regulate the flow of water and air to the nozzle, and at least one hook disposed on the device to brace or anchor the device to a wall. Also provided is a barrier-penetrating fire suppression system with a penetrator assembly mounted on a vehicle platform boom. The penetrator assembly is perpendicularly aligned with a barrier whereupon a striker shaft propels a piercing nozzle through a barrier before water is sprayed from the nozzle.

Fire protection systems and methods for ceiling-only high-piled storage protection. The systems include a plurality of fluid distribution devices disposed beneath a ceiling and above a high-piled storage commodity having a nominal storage height ranging from a nominal 20 ft. to a maximum nominal storage height of 55 ft. and means for quenching a fire in the storage commodity. The stored commodity to be protected may include exposed expanded plastics. The fluid distribution devices include a frame body having an inlet, an outlet, a sealing assembly, and an electronically operated releasing mechanism supporting the sealing assembly in the outlet.

A firefighting system is delivered from a helicopter and capable of dispersing foam, water, or a chemical flame retardant at a given distance upon a conflagration. The system has a plurality of wheels secured to an underside surface which permits the system to be easily moved from beneath a helicopter to be recharged. The system is configured to operate in conjunction in low light or low visibility conditions.

There is described a fire-fighting apparatus comprising a housing comprising an upstream air inlet and a downstream fire-extinguishing stream outlet and a hollow body therebetween, wherein the housing houses an air stream traveling at high velocity; and a spray assembly concentrically mounted to the housing. The spray assembly comprises a fluid inlet connected to a source of fluid outside the housing; and a plurality of injecting assemblies fluidly connected to the fluid inlet and designed for breaking down an inflow of the fluid into droplets and projecting the droplets of the fluid within the air stream in a multiphase fire-extinguishing stream. The injecting assemblies each comprises a fluid outlet; a base plate through which extends the fluid outlet; a holding structure mounted to the base plate and extending downstream therefrom, and a unibody jet-fragmenting device mounted to the holding structure facing the stream of fluid exiting the fluid outlet.

The present invention relates to an in-building access path installation type smoke control system. An in-building access path installation type smoke control system is openably and closably installed in an in-building access path and includes a door casing having an intake port and a discharge port, a door nozzle installed in the door casing and configured to spray water supplied from the outside, and a main door body including a negative pressure inducer configured to allow water sprayed from the door nozzle to pass therethrough, generate negative pressure on the basis of the Venturi effect while the water passes therethrough, suck gas at the periphery of the door casing through the intake port, mix the sucked gas with water, and move the gas mixed with the water downward toward the discharge port.

Disclosed herein is an Ambient Mist Sprinkler head for extinguishing fires that comprises a plurality of mist nozzles attached to a head. The Ambient Mist nozzles are arranged spatially on the head at various angles. The number of mist nozzles, the spatial arrangement and the angular placement of the mist nozzles can vary, depending on the area of coverage required. The angular placement of the mist nozzles on the head is effected so that the mist nozzles stream emerging from one mist nozzle does not impinge on a mist stream emerging from another mist nozzle while providing a maximal amount of mist production, and minimizes the occurrence of streams of water droplets. The present invention relates to Ambient Mist Technology and relates to tools that employ Ambient Technology in combating fire, smoke and airborne pollutants. They do not require gravity to work and can be used at any angle required.

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.

Fire protection systems and methods for ceiling-only high-piled storage protection. The systems include a plurality of fluid distribution devices disposed beneath a ceiling and above a high-piled storage commodity having a nominal storage height ranging from a nominal 20 ft. to a maximum nominal storage height of 55 ft. and means for quenching a fire in the storage commodity. The stored commodity to be protected may include exposed expanded plastics. The fluid distribution devices include a frame body having an inlet, an outlet, a sealing assembly, and an electronically operated releasing mechanism supporting the sealing assembly in the outlet.
