Question

I have Nicor PRCP2 and want to know if wired ring doorbell is compatible because I can’t find 'trans' and 'front' on existing transformer. I must be doing something wrong. Thanks

Hi @user46124. The [Video Doorbell Wired](https://ring.com/products/video-doorbell-wired) will not ring any pre-existing chimes. The Jumper Cable needs to be installed and will bypass the chime. Since your chime does not have a front and trans terminal, you cannot install the Jumper Cable. You will have to hardwire your Doorbell directly to a transformer (10-24 VAC, 40 VA max, 50/60 Hz). This Help Center [page](https://support.ring.com/hc/en-us/articles/4405783047188-Wiring-Diagrams-for-Ring-Video-Doorbell-Wired-) will give you a schematic of how this installation looks. If you are not comfortable doing so, we recommend consulting a qualified electrician for help. You can also use a [Plug-In Adapter (2nd Generation)](https://ring.com/products/video-doorbell-plugin-adapter-gen-2) to power up your Doorbell Wired. I hope this helps.
