If you have a NFPA 110 Level 1 EPS/EPSS consisting of a diesel generator outside and ATS's in a room inside along with DP's off each [i.e. your EPSS], does the EPSS room need to be fire rated.

Also, and related; If it's neither an assembly area nor a high rise, then Article 700.10(D) does not apply so the rooms with the Emergency Panels down stream of the EPSS do not need to be rated. Do you agree?
