Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. This hot air rises and spreads along the ceiling. When the air is hot enough and reaches a sprinkler head, it triggers a chain reaction.

All fire sprinklers are one of four types: pendent, upright, sidewall, or concealed

A fire sprinkler system is a simple, but key, active component of a domestic or commercial building’s fire protection system. Installed in ceilings or side walls, the system consists of a water supply, a water distribution piping system and sprinkler heads.

A dry pipe sprinkler system is one in which pipes are filled with pressurized air or nitrogen, rather than water. … Located in a heated space, the dry-pipe valve prevents water from entering the pipe until a fire causes one or more sprinklers to operate. Once this happens, the air escapes and the dry pipe valve releases.
