When should sprinklers be tested for proper operation?

Sprinklers should be tested for proper operation annually to ensure they remain effective in the event of a fire. This annual testing aligns with the maintenance requirements outlined in the NFPA 13 standard, which emphasizes the need for regular inspections and testing of sprinkler systems. The rationale behind this frequency is to verify that all components are functioning correctly, that the system is in good condition, and that any obstructions or damage are identified and rectified promptly.

Testing only during a fire event would not provide any preventative maintenance and could lead to systems failing when they are most needed. Monthly tests, while they may seem like a proactive approach, are typically not feasible for the comprehensive evaluation required and could lead to unnecessary wear on components. Testing every five years would not be sufficient to maintain operational readiness and could result in undetected issues that may compromise safety in the interim period. Therefore, the annual testing requirement helps ensure that the sprinkler systems remain reliable and effective in providing fire protection.
