Can you use the window sensors you already have from another system

Hi there. No, the Ring Alarm System is not compatible with third-party alarm sensors. You will need to use Ring Alarm Contact Sensors for your windows. Some existing wired alarm sensors may be compatible with the use of the Ring Alarm Retrofit Kit, but it does not work for wireless sensors. You can read more about the Retrofit Kit here: https://support.ring.com/hc/en-us/articles/360032456492-Welcome-to-the-Ring-Retrofit-Alarm-Kit. All the best, Ashley from Ring.
