Which sprinkler head is designed to hang from the piping and face into the room?

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

Answer: (A)

Sprinkler heads come in different orientations to suit how the piping runs and how the spray covers the room. A pendant sprinkler head is mounted by hanging from the piping, with the deflector below and the spray directed into the room. This hanging arrangement is exactly what makes it the design that faces into the room after being installed on a piping run.

An upright head is mounted on top of the pipe and projects into the space, but it isn’t hanging down from the piping. Concealed heads sit flush with the ceiling behind a cover plate, hiding the head from view. Deluge heads refer to the system type where all heads are open, not to how a head is oriented.
