Why does the zone light on the D360 Command Center light when the D279A is disarmed?
The D8112 panel is programmed with a zone code of 3271 on a particular zone. The purple jumper on the D279A is cut. As a result, the D360 zone light illuminates when the D279A is disarmed.
This is normal and will not impact the D8112 arming process. If the D1252A is used, the disarm state of the D279A is not indicated.
