Positioning
CAREFUL POSITIONING IS ESSENTIAL TO 
OBTAIN OPTIMUM PERFORMANCE.

Use the detection range to determine a 
suitable location for the sensor. When 
locating the position of the units, ensure 
the sensor is not subjected to bright or 
direct sunlight or in areas with high 
refl ective surfaces. Do not site units on a
vibrating surface, or near forced air

heating and ventilation. They should not 
be placed within 1 metre of the load.

Sensors work when objects move across 
their fi eld of view. Position the sensor 
where people will be detected walking 
across the zones rather than towards the 
zones identifi ed in Diagram 1. Adjust 
sensitivity to suit the area that the sensor 
has been installed in.
