Ring Doorbell Wired chime bypass


I’ve picked up a Ring Hardwired. It looks like my chime transformer is compatible, but all the examples/tutorials of the chime bypass process show a chime with four connectors (0, 1, 2 & 3). Mine only has three (0, 1 & 2). I haven’t been able to find any explanations how to wire up my setup.

Before I employ an electrician, is my chime transformer compatible with the bypass, because it’s not clear to me how I should hook up the bypass in my setup:

Thanks in advance :slight_smile:
