Floor-to-floor connection locations
The sprinkler plan will identify the basic location for floor-to-floor
connections of sprinkler loops. Mark these locations at
the floor and ceiling, taking into account the sprinkler and
piping locations.
Note: The floor-to-floor connection may be specified as a
different piping size than the sprinkler loops.
Plumbing connection locations
The sprinkler plan will also identify the basic location for
plumbing connections to sprinkler loops. Mark the appropriate
locations of the plumbing piping/stub-outs/fixtures with
consideration of where the sprinkler piping will be located.
