[QUOTE="HB, post: 1136065, member: 17429"] Normally closed and normally open dictates the state of the relay in the PIR. That zone should be normally closed at rest. Meaning the zone must see the resistor. When the PIR is triggered, the relay opens on the panel then can't see the resistor and will trigger an alarm when armed. [/QUOTE]
