• The garage door contact should be installed in an
inaccessible location.
• The magnet (contactor 2) must be installed on the
moving part and the transmitter must be installed on
the fixed frame of the door.
• The two parts of the contactor (contactor 1 +
contactor 2) must be installed aligned, one in front of
the other. Otherwise it will shorten the detection distance.
A complete misalignment of the installation will render
the device unable to detect an opening.
It is recommended to mark with a marker before
drilling.
