Secondly the doubling of resistor value may or may not work as you are effectively halving the change seen by the panel, in your example one leg going open circuit will not then show infinite resistance, but 2K instead of 1K. Depending on the panels sensitivity to resistance (voltage) change on the zone
This is totally the crux of the multiple resistor scenario. We don't know what the range of EOL resistance is that won't trip the alarm. That info is needed to know if two resistors could be used.
