What defines “system maintenance” in the context of NFPA 13?

Defining "system maintenance" within the context of NFPA 13 encompasses the range of activities aimed at ensuring that sprinkler systems operate effectively and comply with relevant codes. This involves not only conducting periodic inspections but also performing routine testing, system assessments, and making necessary adjustments or repairs to maintain the system's overall functionality. By ensuring that systems are up to code, maintenance supports the reliability and safety of fire protection systems, which is essential for minimizing risks in the event of a fire.

The approach to maintenance outlined in option B aligns with the principles of NFPA 13, which emphasize proactive measures to prevent failures and guarantee that the system can perform as intended during an emergency. This broad definition includes regular inspections, preventive maintenance tasks, training personnel on system operation, and making repairs as needed—not just in response to failures, but as part of a comprehensive maintenance strategy.
