11.1 Precautions before installation - MW section
Before positioning the barriers outside, you must bear in mind that the lobe generated by the
microwave can reach a width of 4-5m depending on the length of the section.
This zone must be completely clear of objects, buildings, vehicles and fences to avoid wave
reflections that would cause abnormal operation with generation of alarms.
MANA DT SMA
It should also be considered that due to the effect of the generated lobe, there is a dead zone in the
immediate vicinity of the columns.It is therefore necessary to make intersections between the
barriers, which cancel any possibility of crossing in said area.It is recommended to always place 2 TX
or 2 RX at each intersection, with different frequencies out of the 4 available.
