Is the valve UL Listed for Fire Protection? Does the valve have an FM Diamond on it?
If it does then you are good to go... if it is simply a level handle, if I understand correctly, it probably isn't.

The problem with the lever-type valves is that they don't meet the 5 second 'slow close' requirement of 13-13 6.7.1.2 that the hand wheel valves do, and therefore aren't permitted to be used as indicating control valves in sprinkler or standpipe systems.
