configuration is only functional if binary input #1 is set to
Motion NO or Motion NC or a PIR accessory cover is

With this sequence enabled, the occupancy is now
dictated 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.
