6 SENSOR POSITION
If the sensor is facing downwards, the detection distance and the inclination of the
sensor needs to be adjusted so that the floor is excluded from the protective field.
Moreover, it is suggested that 30 cm (11.8 in) be left between the end of the protective
field and the floor, to avoid false alarms due to the tolerance area.

Outdoor installations
6.7.1
Position exposed to precipitation
If the sensor installation position might be exposed to precipitation that can cause
undesired alarms, it is recommended to take the following precautions:
l
make a cover to protect the sensor from rain, hail or snow
l
position the sensor so that it does not frame the ground where puddles might form
6.7.2
Recommendations for covering the sensor
Below are some recommendations for creating and installing a sensor cover:
l
height from sensor: 15 cm (6 in)
l
width: minimum 30 cm (11.8 in), maximum 40 cm (15.7 in)
l
protrusion from the sensor: minimum 15 cm (6 in), maximum 20 cm (7.9 in)
l
water outflow: at the sides or behind but not in front of the sensor (the cover should
be arched and/or tilted backwards)
6.7.3
Recommendations for positioning the sensor
Below are some recommendations for defining the sensor position:
l
height above the ground: minimum 10 cm (3.9 in)
l
suggested inclination: minimum 15°
Before installing a sensor facing downwards, make sure there are neither liquids nor
radar reflective materials on the floor.
