Abstract (en)
[origin: EP1204083A1] The alarm and surveillance unit has a central unit and a peripheral detection intrusion unit with a radioelectric connection. There are several redundant channel radio frequency connections. There is a unit which counts the number of channels available. Signal transmission (5) is then carried out only on the channels available selectively activating the signals as a function of the command state.
