PURPOSE:To set an alarm state even by a lock by a key by outputting a constant time timer signal by detecting the lockin operation by the key, and setting the alarm state when the fact that all openable units are closed and locked is detected at the outputting time of the timer signal. CONSTITUTION:Key lock detecting means 57 for detecting the lock by the key of an openable unit is connected to timer means 59, which si started driving by the output signal of the means 57 to output a timer signal to auto-theft alarm discriminating means 61 only during the prescribed time. Thus, when the means 61 inputs an enging stop signal from engine stop detecting means 51 and inputs at least the timer signal, and when the fact that the all units are closed and locked is detected from output signals of the open/close state detecting means 53 and locked state detecting means 55, a warning unit is set to an alarm state. |
