What is one area that a 13R sprinkler system does not protect?

A 13R sprinkler system is specifically designed for residential settings, primarily focusing on areas that are typically occupied and used for living purposes. This system is effective in providing fire protection in spaces like lounges, kitchens, and hallways, which usually contain furnishings and building materials that can support a fire.

However, the attic area is not commonly protected by a 13R system. This is primarily because attics are often used for storage and may not have the same occupancy risks as living spaces. Moreover, the design and layout of a 13R system may not extend to these less-frequented spaces, which can present challenges related to the ceiling height and accessibility for effective water distribution.

Therefore, understanding the intended use and coverage limitations of a 13R sprinkler system helps clarify why the attic area is typically excluded from its protection scope.
