<p>A partitionable antitheft system remotely activable and disactivable utilizes the same remote control for commanding both the activation/disactivation of the antithievery system and for excluding (partitioning) a certain function of the system. According to a preferred embodiment, the partitioning takes place by maintaining pressed the push-button for remotely activating the antitheft system for a time exceeding a certain reset time interval. By further persisting to keep pressed the push-button, it is possible to implement also a second partitioning by excluding a second function of the system and so on. Existing systems may be retrofitted according to the present invention by adding a ramp generator circuit (R61) with an appropriate time constant which is triggered by the decoded signal received by the antitheft system and by utilizing the output signal of such a ramp generator circuit for implementing a reset function upon a particular flip-flop (F/F1) acting as a switch to enable or disable a certain system's function.</p> |
