Why Does My Nest 2.0 Wired Chime Unexpectedly

[khouston10]

I have an issue with an installation of Nest Doorbell Wired Gen 2 Camera at condo property I have. I connected the existing Chime to the doorbell and it works fine.  However, randomly, and not all the time, there is a faint chime sound.  My first thought is there is small short in the wires.  My second thought is that it will do this anytime the doorbell detects activity outside.  Any thoughts of which could be happening, if not both?

The doorbell does not trigger your indoor doorbell chime when it detects activity.

However, your chime puck may be wired incorrectly; see the diagrams here:

Or you may need to upgrade your transformer; see this Help topic:

Years ago, we upgraded to a 16V 30VA transformer for our 1st gen doorbells.

In my case I did not use the chime puck. I used the existing wiring with the existing chime.  Is this something that doesn't work?

Google Nest's documentation says that you need the chime puck.

We've had a chime puck connected for years on our indoor doorbell chime for each of our two 1st gen Google Nest Hello Doorbells.
