What standard covers low-rise residential sprinkler systems?

• A. System Types
• B. NFPA 13R
• C. Care and Maintenance
• D. Inspection, Testing, and Maintenance

Answer: (B)

NFPA 13R is the standard that covers low-rise residential sprinkler systems. It sets the design, installation, and acceptance criteria specifically for automatic sprinkler systems in residential occupancies that are typically up to four stories high, such as single-family homes and small apartment buildings. This standard focuses on providing reliable protection for dwellings while balancing cost and practicality for low-rise settings. Other options don’t fit this particular scope. NFPA 13 covers broader commercial and industrial sprinkler installations, which have different requirements. NFPA 13D is for one- and two-family dwellings, but not for low-rise buildings that include more than two stories. The remaining choices relate to types of system classifications or to maintenance activities, not to the standard governing low-rise residential sprinklers.
