How do you hook up wired motion sensors to Ring retrofit?

I have a honeywell alarm system with every single sensor hardwired. I moved to XFinity 2 years ago, and they added their own retrofit kit, new keypad’s and were able to re-use my existing wired motion sensors.

If I move to Ring, I don’t see a clear way how to connect the hardwired motion sensors.

Has someone else done it and can share details?


Hey @devilishy. The Ring Retrofit Kit does not allow for anything other than wired contact sensors to be connected to it and be monitored. The Retrofit Alarm Kit can monitor wired contact sensor zones (contact sensors are usually used for doors and windows). You can also visit to learn how other wired security devices can be connected to the Retrofit Alarm Kit. If you have wired indoor and outdoor sirens, wired smoke or CO detectors, wired keypads or other security devices, they are not supported and should not be added to the Retrofit Alarm Kit.
