Questions and Answers for Heath Zenith Wired Doorbell Chime with Cover, Satin Nickel

A:  No, this doorbell has a sound bar that is not adjustable.

A:  I do not think so. It has two sounds as they claim in the package "ding" and "ding-dong" :) that you can get by wiring either the front or rear bells contacts

A:  This doorbell does not have a built in transformer. If you currently have a wired doorbell in your home, then most likely you already have a transformer. If you don't have a wired doorbell already, you will need to get a 16 volt, 10 watt transformer (like the DW-122 on this website).

A:  I think you need to have a transformer already, or buy a new one. This is just the ring bell
