Abstract
Improvements in a vehicle security system control circuit, characterized in that it comprises an impact detector series circuit and a trip series circuit, said impact detector series circuit including impact detector switch means having a normal inoperative condition and an operating condition representative of an impact condition, said firing series circuit comprising electrically activatable actuator means for, upon activation, operating a vehicle security device, power supply circuit means energy to provide operating voltage for said circuits, second switching means provided with a normal condition and a driving condition for connecting together and in series, said detector series circuit and said series trigger circuit with said circuit means power supply so that when such means of in detector switch are in the operating condition an activation circuit is completed through said detector switch means and said second switch means for tripping current to flow from said power supply circuit means to activate said switching means actuator, means for the continuous flow of a first test current from said power supply circuit means through said series circuit of the detector to occur, while said second switch means are in their normal condition, means for a continuous flow of a second test current to occur from said power supply circuit means through said tripping series circuit while said second switch means are in their normal condition, and Outputs sensitive to such test currents to provide an output indication with respect cto a circuit failure in said detector series circuit or in said tripping circuit, depending on the magnitude of said test currents.
