Sprinkler system type where all heads are open and discharge through a common outlet?

• A. Deluge
• B. Wet
• C. Dry
• D. Foam System

Answer: (A)

Deluge systems are built so every sprinkler head is open. When the system is activated, water is released through the entire network and flows out of all heads at once via a single, common outlet. This makes deluge ideal for areas where rapid, wide-area coverage is needed, since there are no individual heads that close off water flow. In contrast, a wet system keeps water-filled piping with heads that operate individually, a dry system keeps the pipes charged with air until activation, and foam systems use foam concentrate for specific hazards.
