DNRW is the NEMA-4 watertight version of the same housing and ships without a head. D365PL is the later housing, carrying the SD365R(A)-IV head that Fire-Lite lists as replacing the SD355R supplied here. The CRF-300 relay module, DST sampling tubes and the RTS151 remote test station are ordered separately.
