A multi-featured electronic vehicle security system includes an output device protection feature, to prevent damage to output devices such as power transistors from damage due to improper installation or miswiring. The system can be user-programmed so that second and subsequent trippings of the same sensor device will result in an alarm condition only if a system trigger device has also been tripped. The system includes a user-enabled feature wherein a first alarm signal generator is activated by a sensor tripping, and a second, distinct alarm signal generator is activated when a trigger device has been tripped. A further user-enabled feature is useful with vehicles having a courtesy light delay timer, with the door trigger wired to the interior light, to permit the system to be actively armed even while the interior light is still turned on. The system entrance delay is automatically bypassed if a sensor device has been tripped. An automatic door lock signal is provided to automatically lock the vehicle\s doors when the system is passively armed but only if the vehicle\s doors have not been opened and closed since the ignition was turned off. The system provides a sensor test mode to permit the sensor devices to be tested without activating the siren for the alarm duration, thereby preventing noise pollution. The system may be efficiently programmed, with the user provided the flexibility of enabling or disabling many of the system features.

An electronic vehicle security system, comprising: means for sensing an attempted unauthorized intrusion event and providing an intrusion signal when the event is sensed; at least one controlled device to be activated in the event of a detected unauthorized intrusion event, said controlled device activated by an output device responsive to an alarm signal; a digital controller for controlling the operation of the security system, said digital controller comprising: (i) means responsive to said intrusion signal for generating said alarm signal to activate said controlled device after an unauthorized intrusion event is detecting; (ii) means for monitoring said output device to detect undesired high current flow through said device and for turning off said alarm signal when said undesired current flow is detected.
