Sprinklers are simple devices that are individually operated by the heat from a fire. When a fire starts, hot gases rise to the ceiling. If a sprinkler is present, a glass bulb or solder link gets hot and at a specific temperature (typically 68°C), it breaks, releasing a cap and allowing water to flow onto a diffuser.

The diffuser breaks up the water flow into carefully controlled droplets which penetrate the fire plume and cool the burning material to below its ignition point, thus controlling the fire. Only the sprinkler(s) directly over the fire are operated.

The sprinklers are connected to pipework, usually filled with water, which is supplied either from the water mains or from a storage tank via a pump. When a sprinkler operates, the flow of water in the pipework operates a flow switch, which, in turn operates an alarm system. The flow of water is small, usually less than 1/100th of the water used by the Fire and Rescue Service.

Reliable and dependable

Sprinklers do not go off accidentally and are only triggered by real fires. They are also very reliable and only 1 sprinkler in 16,000,000 exhibits any form of manufacturing defect.

Sprinkler is thermo-sensitive quarzoid liquid glassbulb burst actuated type and be standard products from an established firm of repute and standing and approved by an appropriate authority for fire fighting duty.   It should be imported only.

All sprinklers is brass castings polished / chrome OR white (polyester) unless stated otherwise and rated for 12.0 KG/CM2 WG and factory tested for 34.0 KG/CM2.  Sprinklers is pendant OR side wall type as specified and shown on drawings.  All sprinklers shall be provided with an adjustable OR Rosettes escutcheons finished same as the sprinkler head.

Temp. classification of sprinklers in each space shall be as shown on the drawings.  Sprinklers shall be selected for the coverage shown on the drawings and ordinarily be 15 MM.  Wherever the specified sprinkler is not adequate.  The tenderer may offer appropriate size required.  Tenderer are free to suggest alternatively other suitable sprinklers with its justification.
