For centuries, water has been used as a medium to fight fires by cooling the fire. ... A high pressure water mist system goes further: it attacks two elements of the fire triangle: oxygen and heat. This means that water mist combines the suppression effect of gas and traditional sprinkler systems.

The flexible sprinkler hose is a material of fire fighting equipment for the initial-attack of a fire. In a sprinkler system, this flexible hose links fire protection piping to the sprinkler head. ... Excellent corrosion resistance : The corrugated tube is made of stainless steel.

Fusible link fire sprinklers replace that bulb with metal components secured to the sprinkler by a heat-sensitive alloy. Rising temperatures cause the alloy to melt, allowing the metal elements to fall from the sprinkler head and activate the sprinkler.

Upright sprinklers are installed with deflectors above the sprinkler, while pendent sprinklers have deflectors below the sprinklers. Common industry practice is to use upright sprinklers in areas without finished ceilings and pendent sprinklers in areas with finished ceilings.

Most residential sprinkler systems are primarily designed to suppress a fire in such a way to allow for the safe escape of the building occupants. While these systems will often also protect the structure from major fire damage, this is a secondary consideration.

A residential concealed fire sprinkler head is a ‘fast response’, two stage devise, the size of a down light. The cover plates of these units are normally coloured white. In the event of a fire reaching its operating point, the flat plate will drop from the devise and the deflector plate of the sprinkler head will then drop below the ceiling level. As the temperature at ceiling level increase to 74 degrees Celsius, a bi-metal strip activates and releases the seal which enables the full flow of water to be directed towards the fire.

The sprinkler at the top will be extremely difficult to install/service, and has nothing above it to collect heat. The one at the bottom seems more appropriate in case of trash accumulation, but will need to have an aux. drain since it is served by a dry system. We all know that drum drips in remote locations behind locked doors tend to have a higher likelihood of freeze ups.
