note this section was deleted form the 07 edition so thereafter all
preaction systems in STORAGE has an area increase.
The question for the 02 is providing an acceptable level of proof.
Simply saying that a lower temperature rating for the detection/
release circuit is no longer adequate.

Again, even 12.1.6.3 says "The requirements of 12.1.6 shall not

it can be demonstrated that the detection system that activates the
preaction system causes water to be discharged from sprinklers as
quickly as
the discharge from a wet pipe system" Isn't this the basic
assumption with
a single-interlock preaction system?
