How do I test the PIR motion sensor and door sensor?

To test the PIR motion sensor: Enter SERVICE MODE, use UP/DOWN arrows to select 'PIr', press MODE, and the unit will beep and count motion pulses detected. To test the door sensor: Enter SERVICE MODE, select 'dor', press MODE, and open/close the door - the unit beeps and counts each door status change. If no beep is heard, the sensor connection may be faulty. Exit tests by pressing °F|°C twice. (Page 18)
