Using existing wired contact sensors

My house has a lot of hard-wired window contact sensors (20) that all terminate at the exitsting security system. I want to put in a Ring system, but i dont want to pay for and put in new battery powered contact senors. id like to use the existing ones. Is there a way i can convert all the wired senors into z-wave using some bridge device, so that i can connect them to the Ring security system?
