Retrofit kit and smoke detector relay

I'm looking into the wired retrofit kit and ring alarm system. I understand the reasons that the Ring retrofit kit won't support typical 4 wire security system smokes. I don't have 4 wire smokes. I currently have a bunch of first alert smoke detectors with wireless interconnect. When one goes off they all go off. Some are 120v and some are battery. I have a first alert relay taped onto the wired interconnect. When any of the smokes goes off this is relay is tripped. It can be configured as normally open or normally closed. It is then connected to any zone on an alarm panel, electrically it is no different than a contact sensor. With konnected and smarthings I just reconfigure the zone it is connected to as a smoke detector instead of a door or window. Will Ring allow me to configure one of the wired zones on the retrofit kit as a smoke detector? I don't want to use a listner, and don't want to add a zwave smoke that isn't part of my interconnected system.
