Claim 9:
10. The electronic door chime of claim 1, the first circuit further comprising
a second doorbell connector, a second inductor circuit and a second monitor circuit connected in parallel with the second inductor circuit, the first circuit configured to pass a second doorbell current through a second external doorbell device connected to the second doorbell connector;
wherein the second doorbell current is produced by the power supply and comprises a plurality of second currents comprising a second inductor current passing through the second inductor circuit and a second monitor current passing through the second monitor circuit;
wherein the second monitor circuit produces a second trigger sensed signal upon detecting actuation of the second external doorbell device; and
wherein the chiming circuit sends the sound signal to the speaker upon receiving the second trigger sensed signal to thereby cause the speaker to produce the sound.
