Concord 4: What happens if 12V output shorted?

I understand the EOL resistor monitoring to protect tampering. What if the 12V output connected to a motion sensor is shorted, does the panel still work and will this short circuit trigger an alarm?

A dead short on the aux power output should trip the PTC protecting aux power. When a powered device like a motion looses power, it opens the loop, thus tripping the alarm.

Thank you MrRonFL, I feel much better. The install manual should have include this explanation next to the EOLR.

As I often point out: Alarm manuals are written with the assumption that the installer already knows the fundamentals of basic alarm wiring and devices. There is really no consideration taken for the DIY non-professional.
