crossing tests
As mentioned above, the microwave barrier creates a cigar-shaped area of coverage and this
creates a dead zone, that is to say, without protection, in the immediate vicinity of the columns
(both transmitting and receiving).
This area is up to 5m long and is generally covered by using the installation of crossed columns,
near the corners of the perimeter to be protected.
If the installation spaces do not allow the correct positioning of the columns, the use of the DT3
sensor is recommended, which uses a 24GHz microwave with Doppler effect.
This is placed inside the upper part of the columns, creating a mini curtain, on the same axis as
the main microwave.
It is recommended, if possible, to bring the alarm output to an alarm control panel input to check
its status and event storage.If this is not possible, it is advisable to put it in series with the main
microwave.
