Good afternoon,
I'm planning to purchase a Nest Doorbell (battery), and I've yet to find a conclusive answer to a question I have about chimes. I understand that the ND can be hard-wired with a transformer and an existing powered chime, but my question is more related to how the chime trigger operates. Can the ND be used to trigger a chime without the transformer? I.e. will it close a circuit when the button is pressed, even if it is not fed from a mains transformer?
What I'd ideally like to do is re-use an existing Byron SX15 wireless doorbell system. It was in the house when I bought it, and the SX-15 units receive a wireless trigger and then use their massive D cells to ring an actual bell that could wake the dead. In our large Victorian house, it's perfect for both audible range and style. What I was hoping to do is to be able to have the ND on a base on the wall outside, and hide the old SX-15 doorbell circuit board within the base, wired to the trigger of the ND. Ideally, a visitor would push the ND, which would close the circuit on the SX-15 doorbell, triggering the wireless chimes indoors.
This might be a stretch too far, but it seems a shame not to try and re-use existing door chimes when there's already so much e-waste in the world.
Any thoughts and assistance are gratefully received. Thank you.
