Static vs. Dynamic Radiation Dampers

Just got the new 2021 IMC and found that the static/dynamic requirements for fire dampers have been extended to radiation dampers as well. After doing some checking online, it appears that all ceiling radiation dampers are static, no dynamic.  In fact, the specs for them don’t even address the issue. I just found some information/discussion that they are ALL static only.  The problem is I most often see them in apartment dwelling units, where the furnaces do not shut down in the event of a fire. Does anyone have any more info on this?
