A disconnection detection device is provided with a disconnection detection unit including a constant current circuit configured to supply a constant current for disconnection detection to at least two horns through wire harnesses, and a disconnection detection circuit configured to determine the presence or absence of disconnection of the wire harnesses by monitoring an output voltage of the constant current circuit and configured to supply drive power through the wire harnesses by turning on the contact circuit independently of the horn switch in a case where disconnection of the wire harnesses has been detected. The disconnection detection unit is disposed in the relay box along with the plug-in relay.
