A multi-featured electronic vehicle security system is disclosed. The system is controlled by an electronic controller such a microcomputer. To reduce noise pollution due to false alarms caused by repetitive tripping of the system sensor devices, the system will not respond to more than a defined number of successive trippings of the same sensor device to initiate an alarm condition. 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. When the system is passively armed, active sensors and triggers are automatically diagnosed and bypassed, permitting the system to be passively armed even if one or more trigger or sensor is active. The system can be programmed so that if the system is disarmed by a remote control and the doors are automatically unlocked, the system will automatically rearm and relock the doors if a door is not opened within a predetermined time interval after disarming with the remote control. |
