For best results:
•  Place the sensor out of direct sunlight and moisture.
•  Position  the  sensor  so  that  it  faces  the  main  unit, 
minimizing  obstructions  such  as  doors,  walls  and 
furniture.
•  Place the sensor in a location with a clear view to the 
sky, away from metallic / electronic objects.
•  Position the sensor close to the main unit during cold 
winter  months  as  below-freezing  temperatures  may 
affect battery performance and signal transmission.
 TIP   Ideal  placements  for  the  sensor  would  be  in  any 
location on the exterior of the home at a height of not more 
than 1.5m (5 ft) and which can shield it from direct sunlight
