retrofit kit with motion and contact sensors?

I have a working alarm system in my home, with several zones. I would like to move to the Ring alarm system, and I understand a retrofit kit would allow me to using my current wiring. Does anyone know if I need would still need to purchase mulitiple contact sensors, range extendor, and motion detectors? I understand I would need to purchase a keypad, but do I need a standard Ring package if I’m using my current wired system with the retrofit kit? Thank you

Good question @nilesmurdoch! The Retrofit Alarm Kit is designed to utilize existing wired sensors, however, we always recommend adding more to your “Ring of security” with additional Alarm sensors. More information about the Retrofit kit can be found in our Community announcement post. I hope this helps! :slight_smile:
