    NFPA 25

    Understood. Maybe the question should be. "If a contractor was to impair the sprinkler the system for 6 1/2 hours by removing the jockey pump from operation, would it be required to notify the AHJ for his/her requirements for the down time?" Where in code would the "yes or no" answer be found?

If a contractor was to enact a predetermined campus power outage for 6 1/2 hours which would certainly prevent the electrical jockey from operating impairing the sprinkler system, what would a contractor doing this be REQUIRED to do by code?
