The Honeywell door chime is encased in a UV-resistant plastic that will maintain its original coloring for an extended amount of time compared to customary plastic models. This product can replace an existing wired door chime and be utilized with either batteries or a transformer. There is an option for two separate chimes that features traditional sound quality. This allows you to add an additional push button to the back door while customizing both chimes to have different sounds. This product is backed by a 1-year warranty.
