The table is used if you have the dry system trip time calculated with a listed program like the one Tyco has, otherwise you have to meet the 60 sec.

Prior to NFPA13 2007, it was clear about the trip time requirement for dry systems. You had the 500 gal size thing, the 750 gal size with accel. thing and the larger systems with the 60 seconds. Now a table for trip times compared to the hazard has been included as well as a test manifold configuration. With a 1300 gal system do I meet the 60 seconds with or without the manifold or do I meet the 50 seconds with or without the manifold? Help, Ron Internal Virus Database is out-of-date.
