BURGLAR ALARM CONTROL DEVICE FOR AUTOMOBILE

摘要

PURPOSE:To set an alarm preparation condition only when burglar prevention is required so as to save electricity where alarm bells are sounded over upon detecting the destruction of the lock of a door and the like by connecting a time setting device between a power source control circuit and a transmitting circuit. CONSTITUTION:Where destructive actions against a door lock is detected by a door lock switch 10 for actuating an alarm unit 37 by a microcomputer 34 based on said detection, a time setting device 26 which sets an alarm condition or an alarm preparation condition at the time required, is provided. Said setting device 26 is connected between a power source control circuit 29 connected to the microcomputer 34 and a transmitting circuit 28. And the transmitting circuit 28 is actuated at the time set by the time setting device 26 for driving the microcomputer 34. Owing to this constitution, when an automobile is parked at a time and a place where no burglar prevention is required, a defenseless condition can be set so as to reduce battery consumption.
