Which NFPA document addresses sprinkler systems for low-rise residential properties?

• A. NFPA 13R
• B. NFPA 13
• C. NFPA 25
• D. NFPA 70

Answer: (A)

This question tests knowing which NFPA standard is specifically written for sprinkler systems in low-rise residential properties. NFPA 13R is the one designed for this scenario, providing installation criteria tailored to homes and small apartment buildings. It aims to deliver appropriate fire protection for residential occupancies while recognizing typical water supply and construction characteristics of that setting, often with simpler or more practical requirements than those used for larger commercial buildings. In contrast, NFPA 13 covers sprinkler installations for most occupancies including larger and more complex buildings, with stricter design and hydraulics. NFPA 25 is about inspection, testing, and maintenance of water-based systems, not the initial installation. NFPA 70 is the National Electrical Code, unrelated to sprinkler system design. So the option corresponding to low-rise residential sprinkler systems is NFPA 13R.
