IQ Smoke Question

Hey there,
Just curious, I know the the maker of the IQ Smoke detector also has a model that looks just like it that has a heat detector built in as well. Would the ones I bought from yall have that in it as well? If so is it all one zone on the panel or do I need to add the heat to a seperate zone? If seperate zone, how do I do this without the panel thinking it is the smoke that I already added? Thanks!

The IQ Smoke has a built in 135 degree heat detector. It is a single zone for both.
