    Abstract: A door chime extender device coupled to an existing conventional door chime that is powered when the switch of a conventional electric chime is activated. The device includes a transmitter with an electricity storage circuit that stores sufficient electrical energy to broadcast an electromagnetic signal that is remotely received by a receiver with an alarm output that activates an audio signal. The storage circuit absorbs sufficient energy from the chime's power source when the switch is activated even for a small period of time.
