装置。[Scope of Utility Model Registration Request] A notification that monitors the voltage of a battery used to back up the power supply of a reporting device that collects information and sends a notification in the event of a power outage, etc., and detects when the voltage drops below a predetermined value. In the battery voltage drop detection device of the device, a pseudo load that flows the same current consumption as the current consumption of the load during the reporting operation of the reporting device, and a voltage supply that supplies voltage from the battery to the pseudo load at predetermined time intervals. and voltage drop detection means for detecting that the voltage of the battery has dropped below a predetermined value when voltage is supplied to the pseudo load by the voltage supply means. Drop detection device.
