ABSTRACT:
An alarm system (10) for use with a vehicle. The system (10) monitors when the driver's seat becomes newly occupied (17) and begins a countdown, during which interval an authorized user can utilize an operator actuated switch (18) to terminate the automatic arming process. If this switch (18) is not used during the predetermined period of time, then the system (10) automatically arms itself. Once armed, the system (10) monitors reception of law enforcement radar signals through use of an appropriate detector (16). When such a signal has been detected, thereby indicating proximity of law enforcement personnel, the system (10) activates one or more alarm devices, each intended to call attention of the law enforcement persons to the vehicle in question, and/or to urge the thief into now leaving the vehicle.
