Have a paddle flow switch for a wet system that is located on the first story riser. The riser serves the entire 3-story building.
When flowing an inspector's test on the first floor or even the third floor, the flow switch paddle only stays engaged for 10-12 seconds before cycling back and forth. Without keeping the engaged position, the alarm won't activate.
Has anyone come across this before? What remedies could help the flow switch operate properly?
