60 second dry pipe trip test

[cda]

When the 60 second trip test is required is it

A. Time it from when you open the inspector test till you get water there

Or

B. from the inspector test is opened , and time it from the dry pipe valve actually trips till you get water at the inspector test

Any Nfpa 13 section to support???
