through those 2 inputs. Any motion detected will set the
zone to occupied status. The zone will remain permanently
in occupied mode until the door contact switch opens
momentarily. The Terminal Equipment Controller will then go
in stand-by mode. If more movements are detected, the
occupied mode will resume. While the door is opened, any
movements detected by the remote PIR sensor or the PIR
accessory cover will be ignored. Use a Normally Closed
contact switching device.

setpoints for the amount of time set by parameter
