4.4.1 Motion sensor placement
For optimal coverage, the motion sensor should be installed on the ceiling as close to the middle of the room as
possible. When ceiling mounting is not feasible, either due to the construction or for the aesthetics of the room,
the sensor may be placed on the wall. The location should be as high as possible and give as much coverage to
the room as possible. Figure 18 shows the range of the motion sensor when placed on the ceiling. This range is
somewhat reduced when installed on the wall. The range shown is a general guideline, and the sensor is designed
to cover an area of about 8m (26 feet)
possible. When ceiling mounting is not feasible, either due to the construction or for the aesthetics of the room,
the sensor may be placed on the wall. The location should be as high as possible and give as much coverage to

to cover an area of about 8m (26 feet)
in diameter.
To check the placement, it is advisable to activate the motion LED using the service device and test the range of
the motion sensor. This process will help to determine the best location of the sensor. See section 4.6 Testing the
In-Room Devices for instructions on this process.
