ABSTRACT:
A vehicle security system includes a plurality of vehicle sensors; an alarm indicator for indicating an alarm at the vehicle; and a controller for generating a first full duration alarm responsive to an initial triggering of a first vehicle sensor after the controller entered the armed mode, and for generating a first reduced duration alarm relative to the first full duration alarm and responsive to a subsequent consecutive triggering of the first vehicle sensor after the initial triggering of the first vehicle sensor. First and second sensors may be alternately zoned in and out if each is triggered a predetermined number of times. In other words, the controller may zone out the first vehicle sensor after a predetermined number of consecutive triggerings thereof, and zone out a second vehicle sensor responsive to a predetermined number of consecutive triggerings thereof and after zoning out of the first vehicle sensor. However, the controller also preferably restores or zones in the first vehicle sensor responsive to zoning out of the second vehicle sensor. Method aspects of the invention are also disclosed.
