Thank you for your question. There is no volume control on this 2-note chime. Something that will normally help is to change the transformer (power supply) to one that has a higher wattage or VA rating. Typically, a 16 volt/30 watt transformer will work in this application. If you need further assistance, please contact our Technical Support group at 888-336-6151.
