True or False: 13R sprinkler systems provide equal protection in all areas of the building.

The statement regarding 13R sprinkler systems providing equal protection in all areas of the building is false. This is because 13R systems are specifically designed to provide a certain level of fire protection primarily in residential occupancies and are often limited in application compared to more comprehensive systems like those classified under NFPA 13, which are intended for all types of buildings.

In a 13R system, water distribution and sprinkler coverage are optimized for places like apartment buildings, where the risk profile may vary significantly from one area to another, such as common areas versus private living spaces. The code allows for different protection criteria based on expected risks, layout, and occupancy characteristics. Thus, not all areas receive equal protection, as the system may provide more robust coverage in certain strategic locations while being less comprehensive elsewhere.

This variability in design and application leads to scenarios where protections are tailored to specific risks rather than uniformly distributed throughout a structure.
