In a seismically engineered building, where non attached structural assemblies are capable of non-congruent movement independently of one another, you are required to separate the two parts of the sprinkler system on either side of that joint. Call it what you want, but in the geological zones where we do most of our work, that is a seismic joint.

I'm talking expansion, not seismic. For example, this will occur where a steel structure (office building) meets a concrete parking garage.
