Abstract:
1. A vehicle security system comprising: a) a controller comprising at least an armed state and a disarmed state, wherein said controller changes said states in response to at least one input; b) a first relay capable of switching from a normally open position to a closed position; c) a second relay connected to said first relay and said controller, and configured to gate said current to said first relay, said second relay configured to switch from its normally closed position, wherein said current is passed to said first relay, to an open position, wherein said current is not passed to said first relay; d) said second relay changing from said normally closed position to said open position responsive to at least one of said current and a control input if said controller is in said armed state, thereby preventing said current from flowing through said first relay to execute its at least one vehicle function; e) said second relay remaining in its normally closed position when said controller is in said disarmed state thereby passing said current to said first relay to execute its at least one vehicle function; and f) wherein said normally closed position of said second relay passes said current to said first relay if said second relay fails.
