The SkyBell Digital Doorbell Adapter will make a digital door chime compatible with the SkyBell Trim Plus. The SkyBell Digital Doorbell Adapter is required for all digital doorbell chimes to work with SkyBell. 

Do I have a Mechanical or Digital Door Chime?

Press and hold the doorbell button. If the chime makes the “ding” sound and hangs, then you have an analog system installed. If the door chime plays a melody or you see a speaker for the chime, you have a digital doorbell.
