Abstract
An alarm device of an anti-theft system for a vehicle is composed of a microcomputer ordinary connected by a power-supply wire to a vehicle battery, an electric-sound-generator driven by the microcomputer, a wire-disconnection-detecting-circuit for detecting disconnection of the power-supply-wire of the alarm device from a vehicle battery, an integrated auxiliary battery connected to the microcomputer and the sound-generator, a transistor for cutting power supply to the microcomputer from the auxiliary battery when the anti-theft system is not on the watch, sensors for detecting access to the vehicle compartment and an outside controller connected to the sensors to turn on the transistor when the system is on the watch and turns off the transistor when the system is not on the watch. If the access to the vehicle compartment or wire-disconnection is detected while the anti-theft system is on the watch, the microcomputer drives the sound-generator to give the alarm.
