of neutralising and or destroying the valuables by an action in positive or negative mode from the armored vehicle the mode of triggering in positive mode is determined by the automatic nature of the occurrence of the triggering of the process if no derogation from the current action is generated during a parameterisable time t the negative triggering mode is determined by an intentional action of an external process or an individual on the control command system advantageously the triggering of the target devices 5 associated with the bags 4 transported in the armored vehicle 6 is provided by the remote monitoring unit 14 on reception from a member of the team in the armored vehicle 6 of information relating to an imminent attack or one which is currently being executed if during the transfer one of the bags containing a target device 5 in active mode is removed from the security perimeter p 1 defined by the transceiver 2 of the gateway 1 or from the security perimeter p 8 defined by the transceiver 8 of the armored vehicle 6 or from the security perimeter p 10 of the transceiver 10 of the reception center the target device no longer receiving any activation signal from one of the transceivers 2 8 10 goes from active mode into triggered mode at the end of a predetermined time of n seconds n being parameterisable the triggered mode is managed automatically by a program contained in the microprogrammed system 26 of the target device 5 which no longer receiving information coming from the radio frequency coupler 24 the latter itself no longer receiving information from any radio frequency transmitter whatsoever and.
