Transformers and Batteries for Your Chimes

Doorbell transformers and "bell wire" are necessary components of a wired doorbell installation.  A doorbell transformer coverts the high voltage electricity in your home to a lower voltage for your doorbell product.


A doorbell transformer is used to connect your wired doorbell to your home's power supply and transform it into a voltage your wired doorbell can use. The doorbell button and wired doorbell are both connected to the doorbell transformer with "bell wire."

From the doorbell transformer, your doorbell button is connected using approved bell wired.  Your wired doorbell also connects to your transformer using bell wire as well.
