Simply plug the SoniCord into any 120V home outlet and the appliance to be monitored into the opposite end. When the power fails to the appliance for any reason, including arc-fault circuit breaker nuisance tripping, the SoniCord emits a loud 80dB signal for up to 2.5 hours. The SoniCord is perfect for use with refrigerators, freezers, sump pumps, aquariums, wine cellars and much more.
