Matt,
I don't know about the 2009 version of the IFC, but 2006, 903.4 requires
water-flow switch supervision, which I interpret to include the 1/2 alarm
line valve. I learned my lesson the hard way on this many years ago when I
got called on it by a fire marshal.

Read the exceptions to IFC Section 903.4. You would normally lock or seal the
1/2 trim valves and not provide electronic supervision.

I believe the locking exception in IFC IBC only applies to Dry,
Preaction Deluge systems. Wet systems still require electrical
supervision according to IFC IBC.

Was there no water flow switch on the system riser?

So it wasn't directly on the riser it was on the trim piping.
