There are clear exceptions for freezer in NFPA 25 '02 12.4.3.2 and 12.4.4.2 for freezers. If this is not a freezer there is some gray in 12.4.3.2 for pre-action and deluge that could get you to the same place. I think because if something could go wrong during a fire and a crafty lawyer could use what I see is gray against you I think you should get things in writing from the owner and AHJ if you are not doing a full trip tests.

We don't inspect a lot of preaction systems, but all of the owners have not let us do a full trip, they are afraid of water leaking out of the system on to their equipment.
