Add heat sensor support to Ring Alarm Retro Kit

I’ve installed the Retro Kit to my Ring Alarm and would like to add my two wired heat sensors to the system. The problem is that my current heat sensors are normally open switches. I’m confident that normally closed heat sensors would work with the Ring Alarm but it would be seen as a door/window. This would cause the police to be dispatched instead of fire should the sensor be tripped. It would be great if hard wired support could be given to both normally open/closed heat sensors including configuration as a heat sensor.
