If you look at Tyco's new pre-action valves they show a butterfly valve installed at the top of the riser to do full trip tests without filling the system.

The system is double interlock. The purpose of the valve would be to permit a full flow trip test, per 25, without flooding the system piping. The system protects a Tier III data center and they are not going to allow flooding of the piping if there are other options available. How common is this arrangement? Any pitfalls?
