According to this method, activation takes place as a result of the actuation of a first control member of an electrical contact, such as the contact key, de-activation being obtained as a result of the actuation of a second control member of an electrical contact. The method is characterised in that the first and second control members used are the same member, such as the said contact key connected to the input terminal (BE), and de-activation is obtained by re- establishing contact for a predetermined period of time. The alarm system can be used in motor vehicles. <IMAGE> |
