Door Chime Low Voltage Wiring

Run the two conductor low voltage wiring from the front door to the door chime. Now, run the door chime wiring from the side or back door to the door transformer. These two wires should be marked front and back door to keep them straight. Also run a third wire from the door chime to the transformer. This will feed the power to the door chime. Bring the wiring through the access hole in the chime mechanism. With the wire strippers, strip the outer sheathing from the three wires. On the power feed wire, tie one side of the transformer to the center terminal of the door chime. The other wire connects to the second terminal of the transformer and also to the black wires of the two door wires. Use a wire nut to connect these together. The white wire will connect to the front and back door terminals of the door chime, as you have already marked these earlier.
