I would be interested to see if there is something available for this scenario but I have my doubts, I would think in the case where you have the municipality demanding flow alarms for the sprinkler system the sprinkler and domestic when then need to be separated and could no longer be a combined system. No matter what you have a flow switch set at, there are going to be moments where domestic demand could set it off.
