I have the same problem. 2 transformers have blown when connecting to Video Doorbell Wired. It works initially, but fails very quickly after a few motion detections. I have 120V input coming to transformer (16VAC - 30VA). Output power was reading 17.6V using a multi-meter. Any help would be appreciated? I had considered adding a second device for my back door as well, but hesitate to do so if transformers are going to be a problem. If a second one is added, does that require a separate transformer or will they run off the same one?
Hey neighbors. When installing the Video Doorbell Wired with an existing doorbell circuit, please ensure you are installing the included jumper cable as directed. The Video Doorbell Wired will not work correctly if the jumper cable is not installed on the chime kit.
If you are wiring the Doorbell Wired directly to a transformer, you do not need to use the jumper cable. You will need to ensure that your transformer meets the following power requirements: 10-24 VAC, 20VA min, 40VA max, 50/60Hz. If your transformer doesn’t fit those requirements and you’re still experiencing concerns with the installation, please give our support team a call at one of the numbers available here.
