摘要

The controller includes a microprocessor (Ic) for monitoring the presence of the driver (36) by an infra-red detector in the car, whether the car doors are open or not (39) and whether the doors are locked (37). If the driver leaves the car and leaves the doors open, then after an elapsed time the car alarm (40) is set off. A set time after receiving a setting signal from a remote control unit, the microprocessor is set to monitor the state of the car door and lock, and to raise the alarm in the case of a break in and to disconnect the car ignition (41). The microprocessor has a self test facility (44) to check correct operation. ADVANTAGE- System reminds driver that doors are not locked and alarm not set prior to driver leaving vicinity.
