Amendment 8/15/1980 The scope of claims for utility model registration is amended as follows. O Utility Model Registration Claims An abnormality detection device that individually detects abnormalities in a plurality of functional parts and converts the abnormal state into an electrical signal and outputs it, and an indicator lamp that is provided corresponding to a predetermined functional part and lights up in the event of an abnormality. , a transistor that is turned on by the output of the abnormality detection device to light the indicator lamp; a resistor that branches the current supplied from the indicator lamp to the transistor to form a shunt circuit; A display detection circuit that includes a group of elements that closes a loop of a voltage divider circuit on the low potential side and generates a divided voltage output that is different when the loop is closed than when the loop is closed, and when the indicator lamp lights up or malfunctions. In a central warning system for a vehicle, which has an alarm display element that blinks together when the vehicle starts, and an alarm circuit that blinks the alarm display element in response to the partial pressure output when the loop is closed of the display detection circuit, A start detection device that outputs an output, an alarm display lighting circuit that forcibly lights up the alarm display element in order to detect a failure of the alarm display element prior to starting using the output of this detection device, and a display detection circuit that generates an output. 1. A centralized warning device for a vehicle, comprising: a determination circuit which gives priority to the output of the warning circuit over the output of the warning display lighting circuit and inputs the output to the warning display element when the warning display lighting circuit is present.

Claims (1)

[Scope of utility model registration request] An abnormality detection device that individually detects abnormalities in multiple functional parts and converts the abnormal state into an electrical signal and outputs it, an indicator lamp that is provided corresponding to a predetermined functional part and lights up in the event of an abnormality, and an output of the abnormality detection device. a transistor that lights up a continuity indicator lamp; a display detection circuit that detects lighting of the indicator lamp and detects failure of the indicator lamp by detecting voltage between the transistor and the indicator lamp; In a central warning system for a vehicle, which has an alarm display element that flashes when a lamp is lit and when a lamp malfunctions, and an alarm circuit that flashes the alarm display element in response to the output of the display detection circuit, the vehicle start-up is detected. A start detection device that outputs an output, an alarm display lighting circuit that forcibly lights up an alarm display element to detect a failure of the alarm display element prior to starting based on the output of this detection device, and a display detection circuit that generates an output. What is claimed is: 1. A centralized warning device for a vehicle, comprising: a determination circuit that gives priority to the output of the warning circuit over the output of the warning display lighting circuit and inputs the output to the warning display element.
