Zone Trouble

[aabento]

I have an Omnipro II with firmware fully updated to latest version. One zone (zone 25 or physical zone 9 on the expansion card) keeps reporting trouble and trouble clears in the event log. Nothing is connected to the terminals, only a resistor.

How can I fix this?

So in PC Access go to the Status/Control tab and select Zones.  What is the Loop value for that zone?  Should be 147 or 148 plus or minus 2. If not the resistor is wrong or loose.
