true but the text is weakly worded. The section that references the Table says "based on the hazard" not the type of sprinkler (as does the Table). I believe the intent was for residential sprinklers (for which a 15 sec requirement exists as part of the listing test standard) but writing what you mean can be a challenge. As pointed out by Ed, the 2010 clarifies it nicely. It was an interesting evolution. It started with the standard dry pipe rule: 60 sec for systems greater than 500 gal and said any size system protecting residential dwellings shall not exceed 60 sec. Then it was pushed down to 15 sec.
