I don't know what the fuel load is but 15 minutes is pretty far out there on most fire growth curves.
Many fire sprinkler systems are also acting as detection for fire alarm. A call to AHJ should also ask that question.

From insurance inspector days anything over 3 minutes needs further investigation. I would have called 15 minutes a failure in the 60's and 70's.

How long is too long of a time for a dry valve to trip before it is considered a deficiency? 25 does not specify but 15 min seams too long. Don't have the previous report to compare it to.
