Notification to the Fire Department is not required if the system is returned to service within how many hours?

Notification to the Fire Department is not required if the sprinkler system is returned to service within 8 hours because this timeframe is established to ensure that any potential risks associated with an inoperative sprinkler system are minimized. The 8-hour threshold allows for a reasonable period during which repairs or maintenance can be completed without necessitating immediate notification, assuming that the system is still addressed in a timely manner. If the system is restored to normal operations within this period, the Fire Department does not need to be alerted, as the risks associated with the downtime will be mitigated effectively.
