ABSTRACT:
A power failure alarm for use in sounding a warning in the occasion of a power failure, with built in electrical connectors, and a temporary source of light. The device is housed in a molded plastic enclosure in a rectangular shape and includes an emergency light, night-light, flashlight, and power failure alarm. All unit functions are completely automatic once the unit has been plugged into a standard 120 volt receptacle. The device has a three prong male plug on the back of the body and is designed to occupy one receptacle of a duplex receptacle thus leaving one receptacle still available for use. Alternate embodiments of the device are specifically intended to alert and notify the user of a power failure. The device utilized logic circuitry to determine if a power failure or improper setup has occurred. The battery charging and monitoring circuits ensure the batteries are always charged and ready for use.
