In an automotive vehicle alarm system the opening of selected movable vehicle structural panels when the alarm system is activated initiates the operation of a first timer's timing sequence which cause alternate operation of low and high frequency or sound level blasts from selected horns; flashing of all of the directional lamps; opening of the electrical supply to the vehicle ignition fuel pump and starter motor circuits and the initiation of a second timer's timing sequence which provides a parallel means for the opening of the electrical supply to the vehicle ignition, fuel pump and starter motor. The timing sequence of the first timer is approximately two to three minutes and cannot be terminated by the closing of the opened structural panel switch which activates the horns and flashing of all of the directional lamps. However, cutting the wires to operational lock switches will terminate the horns and flashing lamps. The second timer's timing sequence of approximately five minutes is uninterruptable in that opening of any switch associated with alarm energizing circuits or the cutting of wire or wires to the initial operational lock switches will not affect the operation of the second timer. During the uninterruptable operation of the second timer, the vehicle operator must wait for the timing sequence to run its course before the car can be started. The system may be activated from within the vehicle interior or exterior thereof. The activating switches may have multiple positions and require inward translation prior to changing switch positions. |
