Abstract
A vehicle security system includes at least one sensor, a controller and at least one output device driver. The sensor has a rest state and a tripped state. The controller has an armed state and a disarmed state. The first output device driver transitions from its quiescent to its alarm state in response to the first sensor transitioning from its rest state to its trip state and the controller is in its armed state and furthermore when the ignition circuit is off. The first output device driver will remain in the quiescent state independently of the present state of the sensor if the ignition circuit is on and the controller is in its armed state. If the controller is in the disarm state, any activity by the sensor will not have any effect on the system.
