Chime problem

Hi , someone know if the doorbell works with Friedland 454?

Hi @user26009. It varies by model of Doorbell if the chime is compatible. What is the model of your Doorbell? You can find the model of your Doorbell in the Ring app or on the packaging. If you’re using the Ring app, you can access the Device Health section by going to the hamburger menu, selecting Devices, and then tapping on Device Health. Is Friedland 454 the full model name of your chime?
