7209048 - Device for monitoring and alerting of a power disruption to electrical equipment or an appliance

The present invention is a simple, inexpensive and reliable device for monitoring and alerting of a power disruption to an appliance or a piece of equipment. An audible and/or visual alarm may be generated in the event that a specific or a piece of electrical equipment becomes disconnected from its electrical source. The device for monitoring and alerting of a power disruption may operate from an internal battery in case the electrical power source to the appliance disrupted. Additionally, a power-surge-suppression, a rechargeable battery, and a charger for the battery may make the device more reliable. The remote receiver may receive a broadcasted alarm signal from the monitoring device and then notify a user with a visual and/or audible alarm at a location where the alarm is more likely to be seen and heard.
