Which NFPA standard is commonly referenced for sprinkler system installation?

• A. NFPA 25
• B. NFPA 13
• C. NFPA 72
• D. NFPA 101

Answer: (B)

The main concept is knowing which NFPA standard governs how sprinkler systems are installed. NFPA 13 is the standard for Automatic Fire Sprinkler Systems, and it provides the design, layout, installation, hydraulic calculation, piping, valve, and testing requirements used during the installation process. This is the baseline reference designers and installers rely on to ensure the system is properly installed and ready for service.

NFPA 25, in contrast, covers inspection, testing, and maintenance after installation. NFPA 72 relates to fire alarm and signaling systems, not sprinkler installation. NFPA 101 is the Life Safety Code that addresses overall safety and egress requirements, not the specific installation details for sprinklers. So, for installation specifics, NFPA 13 is the standard you reference.
