• Select a suitable mounting location on the ceiling.
To be able to use the entire scope of functions of
the presence sensor, the ceiling should not be
higher than 3 m.
Make sure that no electricity or similar lines run in
the ceiling at this location!
Remove the mounting plate (D) by rotating the
•
device and the mounting plate into opposite di-
rections (see figure 3+4).
• Position the mounting plate on the desired site
on the ceiling and mark two bore holes (E) with a
pen to the ceiling (see figure 5).
• Use an appropriate drill to make the holes as il-
lustrated.
If you are working with a stone ground, drill the
marked two 5 mm holes and insert the plugs sup-
plied. If you are working with a wooden ground,
you can pre-drill 1.5 mm holes to make screws
easier to insert.
• Use the screws and plugs supplied to fasten the
mounting plate.
• Do not yet place the presence sensor!
