I am completely confused. 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
