c) Installing the ‘FHT80TF-2’
• Open the casing. Use an appropriately sized flat screw-
driver to carefully push the catches on the left side of the
casing approx. 1 millimetre inwards (‘
A
’), until the half shells
separate.
First press one side catch inwards and pull the casing
approx. 1 millimetre apart at this location. Then press the
other catch inwards; the casing now opens.
• Before the ‘FHT80TF-2’ door/window contact sensor can be
installed at the desired location, both external magnet sen-
sor cables (NC contacts) must be inserted, if available.
On the back side of the door/window contact sensor are 2
openings (‘
C
’), through which the cables can be fed inwards.
• Attach the door/window contact sensor using the enclosed double-sided tape. Or you can
attach it with a screw through the opening ‘
B
’. See figure 15.
Make sure not to damage any power supply lines, gas or water pipes – this may
cause life-threatening danger!
• If you use the supplied magnet (for the internal magnet contact), attach it using the enclosed
double-sided tape (please note the recommended distances that are illustrated in figure 13
on page 22). Alternatively, you can use 2 screws to attach the magnet (remove the magnet’s
casing with a flat screwdriver).
• If you intend not to use the internal magnet contact (left or right) and only intend to connect
external NC contacts, then you can install the door/window contact sensor anywhere near
the window to be monitored (hidden behind a curtain, for example).
