Apologies if this has been discussed previously. Is anyone aware of a code requirement for a "main" flow switch? This would only occur in a building with multiple systems (such as 1 wet and 1 dry, or 3 wet, etc). The "main" flow switch would be located upstream of the individual system risers and would be in addition to the flow switches/pressure switches on the wet/dry systems. I've seen a number of projects where they are called for, but am curious if it's a code requirement or not.
