That makes sense, but I still want an alarm or trouble response from the panel if the sensor detects water. That way it will report to central monitoring even if I am out of the house. I guess I could just have C4 send a push notification etc instead but that gives a bit of ambiguity whereas the alarm/trouble will be acknowledged by the central monitoring company and they would call me immediately.

I know this is a super old post, but did you ever figure this out? I have a water sensor that I assigned to Zone Type 90 so that it would go into alarm but would not trigger the siren, just the keypad beeper when the system is armed, and trouble when the system is disarmed, as well as send the correct codes for water detection when in alarm/trouble and it won't show up in C4. It shows up if I set it to a standard type though.
