In this case, the same philosophy as the single column is applied, but it houses 2 or 3 double TX beams and 2 or 3 RX beams, depending on the height of the column, thus allowing the creation of perimeter protection for any length and shape of the site. All the characteristics and functions are the same as those mentioned in the SANDOR SMA HY line, so it is compatible with the 2 or 3-beam pair in TERMINAL mode.
The latest generation electronic components have enabled increasingly better results in terms of reliability, also thanks to lower power consumption. The distinctive feature of this line is that inside these columns, there is a small power supply with rechargeable backup batteries, providing up to 3 months of autonomy in the absence of the electrical network.
