8.1 Precautions before installation
Before placing the barriers outdoors, you must bear in mind that the infrared beam has a conical
shape: the greater the distance between the column, the greater the diameter of the cone when it
arrives.
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
