Smoke and Heat detector integration

I would like to have a smoke detectors and heat detectors integrated into the Ring system. I disconnected my previously wired system that I had for years, and installed the Ring wireless alarm system. I didn't think about my smoke and heat detectors in the house being wired to the old alarm system. Now I'm without that safety coverage and will have to get battery operated individual detectors throughout the house. I would rather it be tied in to the central alarm security system.
