Zone not being very nice

[bucko]

I am trying to get a zone to work on my M1 panel. It is a valve that was working fine until I moved my M1 about 40 meters away. I have it as a non alarm, n/0
When this zone is open, I now get 2.5K resistance , because the wire run is longer, So the M1 shows it as violated. When the valve is closed, the zone is a direct short, so the M1 reports it correctly.

I've tried to set it up as supervised, but it is not 2.9k, so that won't work either.

Anybody know how I can get this zone working?

Thanks

A valve connected to a zone does not make much sense, but 2.5k ohms is definitely NOT the result of longer wire - open is infinite ohms whether it's a foot or a mile.  Any possibility you have a 2.2k EOLR somewhere in the circuit?

If you added additional resistance with a longer wire run, I would think a lower value EOL should offset that increase back to an acceptable value.
 
Since most resistors are 20% tolerance, I would hope the ELK value window takes that into account.

Something isn't right if you're reading that sort of resistance.
 
Grab a meter and start checking the media....sounds like installation issues with the cabling.

The deal is that I am getting the resistance at the valve switch itself, not from the wire. This motorized valve has a switch inside that monitors the valve state. I think that this valve comes with "Zone" reporting for more $$. The cheaper version (mine) is really the exact same valve without the zone wires present.
 
Strange that this all worked fine while my M1 was being benchtested for 1 year. Now that I installed it, this problem started.

Link to valve's manual?

Investigate the switch then...something is amiss with it, assuming the media is fine feeding it.

Thanks for all your help. I got it worked out. It is all working. 
 
I had a bad beannie connection at the valve end.
