Which type of sprinkler head is designed to be mounted on the underside of the sprinkler piping, hanging down toward the room?

• A. Upright sprinkler head
• B. Pendant sprinkler head
• C. Sidewall sprinkler head
• D. Deluge head

Answer: (B)

Sprinkler heads are designed with how water is released in mind, so their mounting position matters for how the spray pattern fills the space. a pendant head hangs from the bottom of the sprinkler piping and extends downward into the room. This orientation places the deflector below the pipe, directing water downward into the space and then outward to cover the area beneath the pipe.

Upright heads sit on top of the pipe and point upward toward the ceiling; sidewall heads are mounted on a wall and spray outward from the wall; deluge heads are used in all-head-open systems and have open nozzles with water flowing freely to all heads. The description given matches the pendant type.
