Can it be powered by replacing an existing doorbell, or does it still require a new A/C source?

It can not be powered by the doorbell transformer; it requires 6v DC at 1A I believe, which is included in the package. The problem is how in the world do they expect you to connect this in a normal home installation? The wire attached to the adapter is way too short to be useful. I just decided to use batteries.

You can use an existing doorbell. That is what I did and it works beautifully.

It has the expanded functionality to do so, but is not included in this purchase. This doorbell will work with this particular motion detector, supposedly: RCA902N1004/N

Yes but unit is not powerd you'll need an amplifer or thy make one that has amp built in

Yes. Just be VERY careful disconnecting the existing unit as the connections are fragile.

My unit came with a diode across the button. When I later replaced the doorbell button, I had to move the diode to my new button.

We just connected this where our other doorbell was located. Wires pushed into the existing opening. Hope this helps.

Yes, you will need to run a new line from a transformer (not provided) and a line for the indoor speaker. This is a really good system, but the installation on existing construction will not be easy.

I'm sorry, you probably did. An a/c sounds like overkill for such a small unit (I'm pretty sure such appliances need their own exclusive protected socketed, at least that's how we do it in Jamaica).

I don't think so, but it may. The instructions recommend that you remove all existing buttons and use the ones supplied with the new unit. The wall control that comes with it is pretty sophisticated with a sensor eye and several buttons on it. It does only have two screws to attach the wires, so it is possible an ordinary button would work. It also comes with the keypad and two remotes that are quite small, so you may be able to just use one of those instead of an ordinary doorbell button. Sorry, I can't say for sure. You can probably ask Chamberlain Tech Support.

This unit requires a power source. I would not purchase it. I have found better that would work for your application.

No. It is connected to the two wires of your old mechanical doorbell. See skybell.com for further information.

i think so, i sold my home and the doorbell worked perfect. i tried to just get an off-brand but nothing fit or worked so spent the money and glad i did. I remember it working on all the sysytems - mine was out of data but still gets used so (i would replace if i was just buying my hours.

In my situation, the unit plugged into the existing hardware system with no problem or modification. If it does not as in your case, I would look carefully at the directions or call the manufacturer.

Yes, mine is powered and it works fine. A very easy replacement, only took about 20 minutes to install.

Unless our receiver has a switched outlet, you can't.You have to operate it separately

I guess it is possible electrically? You could go into the printed circuit board (PCB) of the button, and wire in your doorbell? The common house doorbell is just a closed wire connection, made by the button after all. But, that would take someone who designs PCB's, and really knew what they were doing. I guess you could do it mechanically too? But, realistically, it isn't made to do that and no one is going to link this product to an existing doorbell. It would be difficult.

My first thought is that the transmitter uses the power when the doorbell unit is energized from the transformer power. This happens when the doorbell button switch is closed to complete the circuit. If the transmitter was wired in series with the transformer, I don't think the doorbell will work due to a high impedance required. Wiring in parallel with the transformer also would not work, since at that location, the power is always present. However, not having tried this, I can only speculate at this point.
