In a Deluge System, what happens when the detection system is activated?

• A. Water is released only at the activated head
• B. Water enters all heads through a deluge valve
• C. Water is released slowly
• D. Water is not released

Answer: (B)

Deluge systems are designed so every sprinkler head is open and ready to discharge. When the detection system is activated, the deluge valve opens and water fills the entire piping network, causing water to exit from all heads at once. This simultaneous, full-coverage release is what makes the deluge configuration unique and suitable for areas needing rapid, widespread flooding. The other described behaviors—water released only at a single head, a slow release, or no release—don’t fit how deluge systems operate.
