What term describes a sprinkler system that connects to the building’s water supply?

A conventional system refers to a sprinkler system that is directly connected to a building's water supply, enabling it to efficiently deliver water to control or extinguish fires. This type of system is designed to work with the existing plumbing infrastructure of a building, drawing water from the municipal supply or an on-site water source. It typically includes networked piping, valves, and sprinkler heads positioned strategically throughout the building to provide comprehensive coverage.

While the other terms may refer to various types of sprinkler systems, they do not specifically indicate a direct connection to the building’s water supply in the same way that a conventional system does. A stand-alone system typically operates independently and usually relies on its own water storage, making it less common in permanent installations. A residential system may imply a more specific application for homes, while a mobile system usually refers to portable apparatuses that can be moved to different locations, rather than being integrated into a building's infrastructure. Thus, the designation of a conventional system accurately encompasses the characteristic of being linked to a building's water supply.
