Which type of sprinkler head is designed to hang down from its supply pipe?

A pendant sprinkler head is specifically designed to hang down from its supply pipe, making it suitable for a variety of ceiling heights and configurations. This design allows the water to be effectively distributed in a downward direction, which is optimal for cooling and suppressing fires that may ignite underneath.

Pendant sprinkler heads are typically used in areas where they can provide unobstructed coverage and where the aesthetics of the ceiling can accommodate their hanging design. They are commonly employed in commercial settings, warehouses, and even residential spaces, ensuring that water is released directly into the fire zone from below, maximizing effectiveness.

In contrast, upright sprinkler heads point upwards and are mounted directly on top of the pipe, projecting water downwards. Sidewall sprinklers are fitted along the side walls, dispersing water in a direction parallel to the wall. Concealed sprinkler heads are designed to be seamlessly integrated into the ceiling, remaining hidden until activated. Each of these designs serves specific applications, but the pendant sprinkler is uniquely suited for a hanging installation, which enhances its functionality in fire suppression efforts.
