Dual frequency technology : ultra-reliable security

Playing the part of the central system linking the devices, radio transmission must be perfectly reliable for many years. The "Dual frequency" technology, resulting from the "fully wireless" concept, satisfies this fundamental security need. All Diagral products benefit from the progress associated with this new technology.

" Dual frequency" technology: two radio frequencies simultaneously This technology is based on coding then simultaneous transmission of information on two different radio frequencies, enabling the system to operate even if there is a problem on one frequency.


Double protection against tamper attempts The simultaneous analysis of two frequencies enables certain and rapid detection of all attempts to tamper with the system. Fraudulent interference is detected within seconds and if necessary, the alarm is triggered. As soon as such interference stops, radio transmission becomes possible again immediately.


Double radio transmission, double antenna, double efficiency Visible symbol of dual frequency radio technology, the double antenna is on all Diagral control panels with integrated sirens and sirens. For other elements, such as detectors, the double antenna is incorporated in the box. top
