Which type of sprinkler can be mounted to the side of the wall?

The sidewall mount sprinkler is specifically designed to be installed on the side of a wall, making it an ideal choice for situations where ceiling space may be limited or where aesthetic considerations dictate a different sprinkler placement. These sprinklers spray water in a pattern that effectively covers the area below and to the sides, providing optimal protection against fire in spaces like hallways or rooms with low ceilings.

This design is advantageous in various settings, as it allows for better coverage in narrow zones while conforming to building codes that may require sprinklers in these positions. Other sprinkler types, such as the ceiling mount and corner mount, are intended for different orientations and spaces. The ceiling mount is fixed on the ceiling, while the corner mount typically serves two walls at the intersection, but isn't designated solely for side mounting like the sidewall type. The wall unit is a more general term and does not specify the same characteristics as the sidewall mount does. This specificity is what makes the sidewall mount the clear choice.
