Selecting mounting location  
The installation of the LC-171 requires a solid, level base for the mounting bracket and must be 
located in a manner that when the detector is mounted, it is facing the center of the desired 
detection zone. 
The protected area must be free from obstacles like walls, fences, trees, ditches and other 
microwave detectors. 
Choose a location most likely to intercept an intruder according to detection pattern on page 5.  
 
Avoid the Following Installation Locations: 
•  Facing direct sunlight. 
•  Facing areas subject to rapid temperature changes. 
•  Mounted at more than 10º from the vertical or horizontal plane.  
•  Facing metal doors. 
•  Near direct sources of heat or airflow. 
•  Clear all physical obstacles from the detection area  
(e.g. Plants, laundry, etc.) 
•  Clear all light reflecting surfaces from the detection area, 
including puddles or other standing water.

Thick vegetation, Grass (un-mown), Water, Sand and Metal.
