Indoor chime working but skips first and last chime of 8 Westminster chimes

[edbett]

System  works as intended with one exception, indoor chime rings immediately at push of Nest camera button but starts the indoor chime one ring late and stops one ring early.  Chime is mechanical with 8 chimes each activated by a rotary cam sequencer switch and normally takes about 8 seconds  to complete the 8 ring Westminster chime sequence.   Have tried using  electronic chime controls and adjusting length of ring  to no effect, works exactly the same if using electronic settings or not, I have not been able to have the indoor chime play its full sequence.   Google has agreed to sent me a replacement  camera since it could not identify or recommend any setting changes which would solve this problem.  I am asking here if anyone has seen a similar situation and figured out how  to make the indoor chime play a full sequence.  Thanks for any suggestions.

Hello edbett,

Thanks for reaching out here in the Community. To make sure that we're on the same page, do you have the Nest Doorbell (2nd gen, wired)? In case you do, 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 doorbell isn't receiving enough power. The Nest Doorbell (wired, 2nd gen) has higher power requirements than most doorbells. Hit this link to check Nest Doorbell compatibility. 

Regards, 

Emerson

Sorry for delayed answer, but I thought I had addressed the power issue earlier. Yes 2nd generation wired. The doorbell transformer meets the required power needed.  There  has never been a  yellow light on the camera, and if the chime adaptor is disconnected, the chime will ring continuously even while the camera is functioning properly.

Hi there,

As we got our resolution here, I'm going to mark this one as resolved. Please feel free to open up a new thread if you need assistance.
 

Thanks,

Thanks for the response.  I checked the transformer and it meets the  spec  before I bought the device, (wired second gen) and have never seen a yellow light.  Google sent a replacement unit, and now the indoor bell doesn't ring at all unless I disconnect  the chime adaptor, and then it rings continuously, so we've switched from one problem to another!  Camera etc. works fine, no issues just the indoor  chime problem.

This video is for the Nest Hello with a Westminster chime, so I don't know if it would apply or not. It makes use of a "relay".

Thanks for the suggestion. It would have been nice if poster included a wiring circuit, almost impossible to follow what he's done.  In the past I have used a relay on my chimes to extend the door-bell press time by 2-3 seconds to compensate for just a very short push which doesn't engage the cam, that is, enough time  for the chime's rotary cam to start the cycle, so I think he's doing something like that, but it was very chime specific as is the video. 

Does anyone know what on the insides of the two wire chime connector?

I can't answer what's in the chime puck, but the purpose is to provide continuous power for the Nest doorbell and its camera, without tripping the chime.

Hi edbett,

Thanks for posting. I apologize for the inconvenience — let's get this sorted out.

While we don't have information on how to connect a Nest doorbell with a relay to work with Westminster chimes, a Nest Pro may be able to help.

If you are in the US, you can contact our installation partner, OnTech, to help you set up the Nest doorbell.

For all other countries, you can book an appointment with a Nest Pro. More information here.

I appreciate the help, Emerson and MplsCustomer.

Best,

Lance

Hello edbett,

Buzzing in — do you still need our help? Don't hesitate to reach back if you do.

Cheers,

Yes I do need help.  As I think  I noted earlier Google sent a replacement unit which has been installed but it did not solve the original problem but created a new problem, that the interior chime does not now work at all, but the camera works well as expected.  Since the change  did not effect the camera at all I am suspicious that the chime adaptor is the issue and have checked the installation (and correct voltage/amperage again) that  the chime connector which I believe is normally a closed connection, is not opening that  connection when a chime request comes from the camera allowing the  indoor chime to ring.  So I'm kind of stuck unless anyone knows more about how the chime connector works or if there is an alternate way of connecting it to make it work properly.  The chime connector is connected directly to the indoor chime terminals thus bypassing the chime circuit when not activated, which is why I suspect the chime connector.   Any thoughts?    By the way so far we've been able to live without the chime using app notifications successfully, and even talking with people at the door when I'm miles away.  My last problem is that I have a medical condition which has weakened my legs so badly that it is almost impossible for me to climb a stepstool to reach the indoor chime and change connections, I I'd like to have some confidence  in a possible solution before I take the risk of climbing the stepstool again, sorry.   Thanks for any suggestions.
