What is the term for an automatic sprinkler system with sprinklers attached to a piping system and a valve opened by a detection system installed in the same area?

• A. Deluge System
• B. Wet System
• C. Dry System
• D. Delayed Auto-Release System

Answer: (A)

Deluge systems deliver water to every sprinkler head at once by using a single valve that is opened by a detection device located in the protected area. Once that detector trips, the valve releases and all heads in the network discharge water simultaneously. This matches the description of sprinklers attached to a piping system with a valve opened by a detection system in the same area, providing rapid, full-area coverage. The other types differ in how they hold or release water: a wet system keeps water in the pipes and only activates the head that reaches its temperature; a dry system uses pressurized air or nitrogen in the pipes and releases water into the network via a remote valve; a delayed auto-release system involves a release mechanism with a delay before water reaches the pipes.
