Zusammenfassung:	Transmitting circuit (14) that is electrically connected to a pair of electrical wires (51, 52) to which a voltage is applied and draws an electric current in from the pair of electrical wires (51, 52) as a drawn current. Determiner (161) determines an operating state including two states that are a fire notification state in which an occurrence of a fire is reported and a coordination notification state in which another device is caused to operate in coordination. When the result of the determination by determiner (161) indicates the fire notification state, controller (162) generates a fire notification by adjusting the value of the drawn current to a predetermined fire notification level. Controller (162) is configured to, when the result of the determination by determiner (161) indicates the coordination notification state, generate a coordination notification by adjusting the value of the drawn current to a predetermined coordination notification level which is different from the fire notification level.
