Multiple Choice

The _ system is equipped with sprinkler heads of the open type.

Explanation:
Open-type sprinkler heads are used in a deluge system because every head is open, so when the system is activated water flows from all sprinklers at once. This setup provides immediate, full-coverage sprinkler protection across the entire area that’s protected. Other systems keep heads closed or require a triggering step before water reaches the pipes, so they don’t distribute water from every head simultaneously.
