If the section that crossed the expansion joint were to be torn apart would it have any functional effect on the bldg. sprinkler or standpipe systems?

As a combo, there's a collection pipe for sectional test and drain discharge, and for reasons peculiar to this building, our first choice is to bring the gang drain back to the riser room, as it's the only place with a SS trap in the basement. We're trying to decide whether a seismic joint is required of the drain pipe, which is normally dry and never under system pressure in any case. I reckon I should know this, but I don't think we've had to address this condition in forever, maybe never.
