Help Replacing Nest wired with 2nd gen wired with 2 chimes

[9ernation]

I am replacing Nest wired doorbell with 2nd gen wired doorbell. I have not been able to find the wiring diagram for one doorbell two wired chime setup and don't exactly know how to connect the chime puck as the original one I was replacing had 4 wires and new one only has two.

Hi 9ernation,

Thanks for reaching out here in the Community. The Nest Doorbell (wired, 2nd gen) has higher power requirements than most doorbells. You need a transformer that is rated for 16-24 V AC, 10-40 VA to provide enough power to your doorbell. If you've already installed your doorbell and you see a blinking yellow light on the front, your doorbell isn't receiving enough power.

Try checking the wiring diagrams in our public article about "Upgrade your transformer for Nest Doorbell (wired, 2nd gen)".

Regards,

Emerson
