Replace your old, worn-out door chime with a brand new chime with the Heath Zenith HE-2216-CA Wired Polyphonic Door Chime. This wired chime features a stylish outer finish thanks to a chime cover with weathered stone appearance. The chime itself offers a total of 4 welcoming polyphonic melodies to choose from, with 3 for the front door chime and one additional melody for the rear. Now, you'll easily be able to tell which door your guests are at. For operation, the wired door chime requires both a low voltage transformer and bell wire (not included).
