Which standard governs the testing and maintenance of sprinkler systems after installation?

• A. NFPA 25
• B. NFPA 13
• C. NFPA 72
• D. NFPA 70

Answer: (A)

Post-installation testing and maintenance of water-based sprinkler systems are governed by NFPA 25. This standard lays out the inspection, testing, and maintenance requirements needed to keep sprinkler systems ready to operate, including how often to perform checks, the procedures to follow, and the documentation to record results. It ensures components like valves, pumps, water supply, and sprinkler heads are functioning correctly and that any deficiencies are addressed before a failure could occur.

NFPA 13, by contrast, focuses on the installation design and construction of sprinkler systems, not their ongoing maintenance. NFPA 72 covers fire alarm and signaling systems, not the sprinkler systems themselves. NFPA 70 is the National Electrical Code, which governs electrical wiring and equipment.
