INSTALLATIONS GUIDE
8.12.1 SECTORS
Having to design protection with volumetric barriers of a closed perimeter within a certain number of
sections that take into account the management need of the entire plant, it must be remembered that it is
always preferable to install an even number of sections. This consideration is bound to the fact that the
likely reciprocal interferences between adjacent sections are annulled should at the vertices of the
polygon (cross), resulting from the installation of the various sections, be installed two equipment with
the same name, two transmitters or two receivers. It is evident that this might occur only if the number
of sections is even.Should it not be possible to have an even number of sections then some careful
considerations must be made on interferences that might likely occur in order to find the vertex point
where retained best to place the transmitter near the receiver. The following pictures show some typical
cases for which the most correct solution is given.
