Thanks for the clarifications from everyone. I will pass it along to the building owner.

After the test the plugs are removed and the spray nozzles are installed, or they can be pneumatically tested at 40 psi as stated on the Contractor's Material and Test Certificate for Aboveground Systems which appears in NFPA 13. If he has a dry pilot actuation system, he may be referring to that for a pneumatic test as well, or for both systems. Foam systems have their own set of tests as do deluge systems when it comes to verifying coverage and impingement on vessels. See NFPA 16 for foam-water systems. I would not blow air through the system to check for "bugs". It should be flushed per NPFA procedures. These kinds of statements don't exude a lot of confidence. Craig L.

I have never heard of this and was wondering what the test entails. Any takers?
