ABSTRACT:
A vehicle alarm system with two-stage disarming consists of a remote control unit, a receiver-decoder unit, a Central Processing Unit (CPU). When the alarm system is armed, the CPU continues to monitor the signals transmitted from the receiver-decoder unit. If no attack is made on the vehicle or no triggering signal is detected by the alarm system, pressing the remote control unit one time will disarm the alarm. When a triggering signal is detected, the siren will sound immediately and the signal lights will flash continuously. To turn off the siren and signal lights, the remote control unit can be pressed one time while the alarm system is continuously and fully armed. If the burglar goes on stealing the vehicle, the siren will sound and the parking lights will flash again as well as that the engine start is disabled. Such full protection remains until the car owner comes back to press the remote control unit twice to deactivate, the alarm.
