This consists of a central control box in which the times both for the sounding of the siren and that for vehicle entry and exit are regulated, a light-indicator box with three possible indications, a siren, a window-raising and door-closing module and a magnetic sensor. The central control box preferably has four relays, the first for control in the delay to rest, for controlling exit from the vehicle, the second for delay of disconnection of the horn, and the third and fourth as delay in connection of the siren. The window-raising and door-closing module preferably has five relays, the first two for combined operation, a third and fourth for closure of each one of the windows and a fifth relay as door closure. The aforesaid module also has three potentiometers responsible for controlling the times, respectively, of delay in exit from the vehicle, of delay in entry to the vehicle and for control of the time of activation of the siren. Lastly, there is a magnetic sensor which can be activated from its corresponding switch and has to be activated upon each occasion the vehicle starts up or moves off. <IMAGE>
