PURPOSE: A burglar-alarm system for a car using an FM radio is provided to promptly inform the existence of a missing car in public to all people, who listen to FM radio broadcasting within a range of passage, when the car is stolen. CONSTITUTION: A burglar-alarm system for the car using an FM radio includes a sensed signal input part(6), a pager signal receiving part(4), a voice input part(5), a voice data storing part(1), an FM transmitting part(3) and a microprocessor(2). The signal input part receives signals generated from a burglar-sensing device. The pager signal receiving part receives pager signals through an antenna when the car is stolen. The voice input part allows inputting a message of the information of the missing car through a microphone. The voice data storing part stores voice signals input through the voice input part. The FM transmitting part modulates the stored voice signals in an FM radio broadcasting frequency band and sends through the antenna in a radio. The microprocessor controls the components. |
