please refer to the illustration.
The different grey zones in the illustration identify the three
observation levels.

The three observation levels are defined as follows:
Near range from 0 m to approx. 3 m.
Medium range from approx. 3 m to approx. 9 m.
Far range from approx. 9 m to approx. 16 m.
The working range specified is referred to an installation height of
2.4 m, with the sensor head not tilted, the movement direction
lateral to the observer, and with a sufficient temperature difference
between the moving body and the environment.
Choosing the Location
To obtain an optimum working range, install the observer at a
height of 2.4 m, laterally to the moving direction, as, otherwise,
losses in the working range will have to be encountered.
Mind sources of interference such as animals, shrubs moved by
the wind, automotive vehicles or lamps within the range of
detection.
If necessary, restrict the sensor range of detection with the
attached slip-fit aperture.
Warning
Caution: The installation and assembly of electrical equipment
may only be performed by a skilled electrician.
Installation
All required screws and dowels are supplied with the unit.
Do not install directly above a lamp. A lamp cooling down may be
detected as a different heat rate and can lead to reclosing.
Choose a suitable place of installation. The detection field should
not be restricted by walls, fences, shrubs etc.
