Abstract

PURPOSE: To enable an abnormal detection even when a stop lamp switch is closed by a method wherein when a check circuit of an indicator lamp in accompany with a stop lamp switch closed is actuated in a collective alarm signal device of an automobile, a lamp is turned ON in a manner different from an input signal of other circuits.
CONSTITUTION: When an indicator lamp L1 is being checked through a depreciation burning during a closed time of a stop switch SW3, a loss of a battery electrolyte level of the power source E is detected by a sensor SR and a sensor signal processing circuit is actuated and further, a transistor Q1 is turned off. When an abnormal signal comes into from the sensor SR, a transistor Q4 is turned ON through a diode D3. Accordingly, the indicator lamp L1 is not depreciated but is turned ON brightly. Accordingly, even when the stop switch SW3 is being closed, an abnormal detection can be performed except the disconnection of the stop lamp.
