Hey, all. A customer requests troubleshooting for an extension door chime for her rear patio, paralleled to the main inside chime and operated by a single door button. There was an old electronic chime that supposedly "worked for a few days" and then both rang when it shouldn't and failed to ring when it should.
I replaced the old unit with a standard solenoid-type chime, which immediately pulled in due to the diode across the button. I know that the diode is required by the inside electronic chime to allow it to complete the programmed chime pattern. The diode also prevents the new chime from releasing, so it hums.
I tried coming up with a way to wire them to operate together, but I can't come up with one. It just so happens that the cables from front door and to inside chime have three wires, but I still can't come up with a way to have the diode supply the inside chime without also energizing the new chime for the outside.
So, my question is whether two electronic chimes will operate in tandem on a single button, as long as they're both the type that require a diode across the button. Have any of you had success with such a setup? We need consistent proper operation without improper "phantom" chiming at the wrong time. Help!
