8.1 Precautions before installation
In order to avoid false alarms, it is advisable to place the barriers away from reflecting surfaces, such
as walls or anything that can attenuate the signal.
DO NOT place the barriers if there are plants, bushes or fixed objects in the range that
obstruct the signal and create "grey areas".Leave a corridor of 50cm for distances between
columns greater than 50m
