The VDB755P is compatible with standard mechanical and digital chimes.
Note: Because the ADC-VDB755P does not draw power from the doorbell chime circuit and transformer, it may be able to operate chimes outside the standard types listed here, similar to an analog doorbell button.
However, Alarm.com cannot test every doorbell chime available to users and, therefore, cannot guarantee or support performance on all chime types.
