A sprinkler system not in operation for how many days may be inspected by the authority having jurisdiction (AHJ)?

The correct answer, which indicates that a sprinkler system not in operation for 30 days may be inspected by the authority having jurisdiction (AHJ), aligns with standard industry practices and fire code regulations.

Sprinkler systems are vital for fire suppression, and ensuring they are operational is crucial for safety. If a system is out of service for an extended period, like 30 days, an inspection by the AHJ is warranted to evaluate the reasons for its inactivity and confirm that all necessary maintenance and repairs have been conducted. This inspection helps ensure that the system is ready for effective operation when required, thereby maintaining compliance with fire safety codes and protecting property and occupants.

The guidelines generally allow for a 30-day window to trigger an inspection, as longer periods without an operational system can increase risk and may require additional scrutiny to ensure safety measures are being upheld.
