With the detection should pick up things in the non-PA space near the boundary so it's just a dry system as it spreads to the PA side of things. The whole non-PA side maybe not. Thinking out loud couldn't the non-PA flow switch be tied into the PA system along with the detection to trip the electrical side of the PA valve? Chris Cahill, P.E.

There is no separation between the two system types.
