Water curtains are commonly created using which type of sprinklers?

• A. Pendant sprinklers
• B. Upright sprinklers
• C. Sidewall sprinklers
• D. Deluge sprinklers

Answer: (A)

Water curtains rely on the sprinkler’s discharge pattern to form a continuous sheet of water across an opening. Pendant sprinklers project water downward from the ceiling, so when several are lined up above an opening, their downward spray creates a steady curtain that can block heat and flame from passing through. Upright sprinklers push water upward or outward and aren’t arranged to produce that vertical curtain. Sidewall sprinklers spray along a wall, not across an opening, and deluge sprinklers flood all heads at once rather than creating a controlled curtain.
