A pendant-type sprinkler head is designed to be installed in which orientation?

• A. Upward from a pipe
• B. On a vertical sidewall
• C. Open, fused
• D. Downward from a pipe

Answer: (D)

Pendant-type sprinkler heads are designed to hang downward from a ceiling pipe, with the deflector facing down into the protected space. This downward orientation ensures the water pattern spreads across the area below, providing effective coverage for typical ceiling-mounted installations and avoiding spray directed upward or along walls. The shape and placement are chosen so heat exposure and water distribution work together to control a blaze in rooms with standard ceiling heights. Other head styles use different orientations—upright heads project into the space above the ceiling, and sidewall heads extend along walls—so they aren’t suitable when a pendant design is required.
