Start-up
5.2.1 Selecting a suitable mounting location
• Select a window or door for mounting the
window / door contact.
• Fasten the window / door contact on the side of
the window or door where the handle is located,
in the upper third of the window/door frame (see
“5.2.2 Adhesive strip or screw mounting” on page
37) (see figure 4).
• The infra-red sensor (E) has to point into the direc-
tion of the window/door casement (see figure 4).
The ideal spacing between the housing edge of
the window / door contact and the window/door
casement should be 3 mm (see figure 4).
• If the window/door handle is located on the right
side you have to turn around the window / door
contact so that the infra-red sensor (E) points
into the direction of the window/door casement
also on this side (see figure 4).
If the window/door casement is too small, the
device can not be mounted.
For poorly reflecting surfaces (e.g. dark window
frames) the supplied reflecting sticker has to be
fixed to the inner edge of the window/door case-
ment on the opposite of the infra-red sensor of
the window / door contact.
