Abstract
PURPOSE:To securely prevent theft by bringing about an alarm condition at the time of turning on an ignition switch unless a code which agrees with a previously set password code is inputted, even if an alarm is not given when a door is illegally opened. CONSTITUTION:At the time of committing an illegal conduct, if a defined code is not inputted through a key board 3 or it a code which is different from the set password code on a memory 4 is inputted, an MCU 2 judges this and keeps the turned-off condition of an OK lamp. After that, when the illegal person starts an engine, an ignition detecting device 14 detect the ON condition and the detected signal is inputted into the MCU 2, which, in turn, operates an inside timer to start measuring time on receiving the signal. On the other hand, a set time is stored in a memory 4 and, as the measured time reaches the set time, driving signals are outputted operating output circuits 7, 8. Thereby, the driving signals are fed from the circuit 7, 8 to a horn driving device 11 and a head light lighting device 12 through signal lines l1, l2. And, then, an exciting current is made flow in a relay RL1 to sound a horn.
