<p>The use of a bifilar bus (18) for connecting support devices (25,60,75) for security codes makes it possible the amount harness to be considerably reduced and a high flexibility degree to be accomplished in the system which consequently is capable of performing a plurality of different functions (alarm, access control, protected functions enabling, actuation of motor units, electronic apparatuses programming) with a reduced number of types of same devices. The security code generation and recognition is simple and is based on one single procedure for all of the functions controlled by the system. <IMAGE></p> |
