Setting The Detection Range - SOMFY 1875108 Manuel D'utilisation

Setting the detection range

The upper beam is fixed: it always remains parallel to the ground. The lower beam can be adjusted
(see below). Given that the beams (lower and upper) must be broken simultaneously to trigger an alarm,
the detector range is limited to the range of the lower beam.
