5.3 Screw mounting
For mounting the passage sensor using screws and plugs,
please proceed as follows:
• Choose a desired site for installation.
Make sure that no electricity or similar lines run in
the wall at this location!
• Slightly press the catch of the device and remove
the electronic unit (A) from the cover (E) (see fig.
3).
• Remove the batteries from the battery compart-
ment (C).
• Use a pen to mark the positions of the four bore
holes of the passage sensor to the wall (see fig. 4).
• Use an appropriate drill to make the holes as
illustrated.
If you are working with a stone wall, drill 5 mm
holes and insert the plugs supplied. If you are
working with a wooden wall, you can pre-drill
1.5mm holes to make screws easier to insert.
• Use the screws and plugs supplied to fasten the
passage sensor (see fig. 5).
• Re-insert the batteries into the battery compart-
ment making sure that they are right way around
(see fig. 6).
• Do not yet place the cap (E) .
