Which type of sprinkler head is designed to be hidden from view in finished spaces?

• A. Pendant
• B. Upright
• C. Sidewall
• D. Concealed

Answer: (D)

Concealed sprinkler heads are built to disappear behind a finish. They sit under a decorative cover plate that keeps the head hidden in ceilings or walls, so the room looks uninterrupted. When heat reaches the sprinkler, the plate is released and the head is exposed to spray, allowing water to discharge. The other types are designed to be visible: pendant heads hang down from the ceiling, upright heads rise from the ceiling, and sidewall heads mount on the wall. This makes concealed heads the choice when finished spaces require an unobtrusive appearance.
