I think Steve and I have discussed this before, but I read it to say that you must provide Class III hose connections on each side of the stage, but if you have a fully sprinklered building you can just provide a single 1 1/2" connection supplied from the sprinkler system. But, it does say in accordance with NFPA 13 or 14 and provide sufficient length of hose. So, I take that to mean if you can't cover the stage with the length of hose provided from a single connection, then you would need on both sides. Is that correct Mr. Leyton?
