You'll notice the similarity between wiring a chime and a doorbell or buzzer. Chimes are usually much more attractive than bells or buzzers. For this reason, you may want to mount them right on the wall in a room. Again, remember that the chime should be mounted in a location that allows you to hear the chimes throughout your home. Read the manufacturer's instructions and follow them carefully.
Many larger transformers require specific wiring arrangements.
9 shows a simple wiring plan for a four-note chime. In the illustration, the transformer is located in an outlet box in the basement, and the wire feeds to the four chimes in the central unit located elsewhere within the house. This type of tester is readily available at most hardware stores and home centers for a very reasonable cost. When problems arise, the doorbell button is usually the culprit. Always check the button first if a doorbell or chime fails to function.
