Where are pendant sprinkler heads typically installed?

Pendant sprinkler heads are designed for installation on the underside of the sprinkler piping, which hangs down toward the room, allowing water to be effectively dispersed in a downward direction when activated. This design maximizes coverage and ensures that water reaches the intended areas below, providing optimal firefighting capabilities in a fire incident. The downward orientation helps to create a more effective spray pattern, which can cover a larger area and reach the sources of fire more effectively.

Other locations, such as the walls or the ceiling surface, may not provide the same level of coverage or efficiency. For instance, wall-mounted sprinklers can create dead zones where water may not reach, and directly mounting on the ceiling surface might not take advantage of gravity to distribute water efficiently. Similarly, top corners may limit the effectiveness of the spray. Thus, the design specificity of pendant sprinklers makes their installation on the underside of piping the appropriate choice for effective fire suppression.
