2nd generation wired doorbell chime connector

Community Member

Has anyone tried to use a simple old fashion single contact switch doorbell without the camera, just the chime connector?  Would like to know if that works to ring the chime or does it damage the chime connector?

Hello edbett,


Thanks for reaching out here in the Community. The Nest Doorbell (wired, 2nd gen) has higher power requirements than most doorbells. For some installations, you'll need to replace the transformer for your Nest Doorbell. You need a transformer that is rated for 16-24 V AC, 10-40 VA to provide enough power to your Nest Doorbell. If you've already installed your Nest Doorbell and you see a blinking yellow light on the front, your Nest Doorbell isn't receiving enough power. Hit this link for more information. Let me know if you have other questions.

Thanks for the info but your answer has nothing to do with my question.  Yes, I have the proper sized transformer, that is not an issue.  Perhaps if explain further... Since it is now winter and zero temperatures and covered with snow, I can't install the doorbell until the weather gets better.  However, I can easily access my chime, where I could install  the chime connector with no problem.  So, if I install the chime connector without installing the nest doorbell, the existing push button doorbell will still be in place.  So, what would happen if the  existing original doorbell is pushed while the  chime connector is installed but the nest doorbell is not?  Will the chime connector work with the original doorbell?  Will the chime connector be damaged if the old doorbell is pushed?  I hope I've made my question clearer... Please let me know..  Thanks, Ed
