Your NuTone Door Chime is designed for three (3) door operation. It will sound either 8 or 4 notes for the front door, one (1) note for a second door and a different note for a third door. Use the NuTone transformer packaged with the chime for best results.

When installing this chime and wiring has been completed, check to make sure that the pushbuttons are in good operating condition. When installed correctly, they must not stick – meaning they must return to the original position to open the circuit.
