I sometimes get zone trouble at any zone that has motion during the arming process. This does not happen every single time, but when it does, all motions thereafter trigger zone trouble. The only way to resolve this is sometimes a reset or disarming the alarm.
Initial I thought it was a faulty PIR, as it was at some point the PIR next to the keypad upstairs, but I have seen over some time that other PIRs that have occupancy at arming do the same.
I have an ULTRA panel. Was about to get version info and just realized that the firewall is now blocking Comfigurator on my old PC and I cannot load it on my MAC.
Did you upgrade firmware recently?
Zone trouble should only occur when there is unknown voltage on the zone terminals. Check the resistance across the zone wires when disconnected from comfort, ie remove the terminal blocks and merasure the resistance on the zone wires with the door or window or PIR closed. the reistanmce should be less than 20 ohms, but If the resistance fluctuates, there is a problem with the wires.

This is a signed vertsion which should be allowed to install
I tried downloading 4.0.4, am getting the same issue.

The problemn should be due to one of the following
wiring problems, either shorted to other wires or voltages or high resistance
intermittent sensor problems
3 damaged zone inputs
The 1st 2 are more likely
To test the 3rd possibility, remove the wires from the affected zone and short the zones with a wire so they are permanently closed. Open and close the wirest and check iof the zone troublks still occur. Leave themin place for a few days as the problem is intermittenm
You can also move the zones to an unused zone, like on a LEM
I would like to add that these zones do not report trouble at all in any other case. The only time that they actually report zone trouble is during arming, and if you arm and then you move away from the keypad, sometimes it then reports zone trouble. Other than that, it never reports zone trouble if the alarm is either off or in a state. They only do that when there's arming, and it's sometimes not always.
tHAT IS strange. I suspect that the voltage at the zone terminlas is close to the threshold of being detected as Trouble. Are you able to measure the resistance at the zone terminal when the terminals are unplugged from the Comfort PCB, and the door or winodow is closed. Measure the resistance for about a minute and check if the value is stable or if it changes. Also do you have End of line resistors at the zones? That will determine what reading you should get

I have downloaded and installed the Analog Input Grapher and we had the same issue again and I was able to capture images and the log.
It looks like I cannot attach the logs or the images, will have to email them.
The permissions to upload fdiles and im,aghes are enmabled. How did you try to do it. ? You can juyst drag the images to the atrtcahment box below, as I have done with the images you sent. the images show that the voltages are within range and do not cause the troiuble.
Are you using No EOL or EOL Resistors. The voltages seem to be not near the open or closed limits
Presumablky you did not get the zone trouible. Leave the software runn8ing and arm and disarm the system until you see zone trouble, then save the image
The was no Attachment block to click or drag to when I posted then.
The alarm was zone trouble on the same zone when those images were captured.
For this PIR, we are using No EOL resistors.
the attached image shows there the attachemnet drag area is, right below the reply window
ig you are not using EOL resistors thaen the voltage rage for on and off is not right. The of volatge shouldbe around 0.1 but yours is 1/2 way to trouble. It looks like your wire resistance wis bery high about 500 ohms. This means the margin to getting trouble is very small
