ることを特徴とする火災報知設備の表示灯。 A converter that connects a series circuit of a resistor and a light emitting diode to the power output line of the fire receiver, converts the current flowing through the resistor into voltage, and a first converter that outputs when the output of the converter exceeds a reference value. A comparator is connected to a second comparator that outputs an output when the output of the conversion circuit is smaller than a reference value, and a notification is made if there is an output from either the first comparator or the second comparator. An indicator light for fire alarm equipment characterized by:
