A transmitter that outputs a signal for displaying a warning, an attenuator that receives the signal output from the transmitter and attenuates the signal level, and an external signal that is connected in parallel to this attenuator and requests a warning display. a switching element that short-circuits the attenuator in response to an input; and an alarm is displayed by the signal that is connected to the attenuator via an impedance element and is output from the transmitter when the switching element short-circuits the attenuator. What is claimed is: 1. An alarm generating device comprising: an alarm indicator that performs the above-mentioned operation; and a detection circuit that detects a voltage across the impedance element to monitor a failure of the alarm indicator and the transmitter.
