What is described as an integrated system of underground and overhead piping designed to supply a suitable water supply?

The correct choice describes an automatic sprinkler system, which is specifically designed to provide a continuous and adequate supply of water for fire protection. An automatic sprinkler system consists of a series of components, including pipes, valves, and sprinkler heads, that work together to deliver water to designated areas in a building in the event of a fire. This system is crucial for controlling or extinguishing fires quickly, thereby enhancing the safety of the occupants and protecting the property.

An automatic sprinkler system is integrated, meaning that it can include both underground piping, which typically carries water from the main source to the building, and overhead piping that distributes water to various sprinkler heads strategically placed throughout the structure. This design ensures that water is readily available where it is needed most during a fire event, supporting effective fire suppression.

In contrast, the other choices refer to different fire protection systems. The automatic fire extinguishing system may include various methods, not limited solely to water but also using chemicals or agents. An automatic water mist system uses fine water droplets to suppress fires but is not primarily focused on the traditional water supply approach like the sprinkler system. Lastly, the automatic smoke detection system focuses on identifying smoke to alert occupants or systems but does not involve water supply for fire suppression. Thus, the detailed
