As far as I know the only time you need specifically listed
concealed space sprinklers is when you're protecting plastic pipe
in combustible spaces with sprinklers attached to the plastic pipe.
Since I'd only be using dry heads in unheated spaces I'd presume a
dry system which you can't use for dry systems or coming from pipe
in a heated space to protect an unheated space so no plastic to
protect. Educate me if I'm missing something.
