Assuming you have a solid floor for the mezzanine, it's treated
separately. To ensure you have a large enough remote area, you
pick up part of the existing system at the roof level.

Dear Forum,
We are currently working on a project where we are tying onto a
dry, gridded
sprinkler system, installed in 1985. There are two existing dry
systems and
they each cover an area of about 13,100 square feet. The lower
floor is a
tree system that was sized by "Table 3-7.1" of NFPA 13, 1984 Ed.
The main
floor is a grid that was designed at a .275/ 3000 square feet with
500 gpm
hose allowance. The addition that we are sprinklering is only
2,000 square
feet. On the main floor of the addition there is a mezzanine of
about 1,000
square feet. Is a calculation even needed for such a small
addition, or can
we use the existing pipe sizing as our guide? If a calculation is
required,
would we calculate the sprinklers along the roof deck by
themselves, or do
we need to include the sprinklers under that mezzanine in our
calculations
as well.
Thanks for the help
