Sprinkling System

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 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 1100th of the water used by the Fire and Rescue Service.
