Bob,
Is there a specific reason you can't use the type of residential
sprinklers which are allowed to be installed
either drilled through the beams, or installed adjacent to the bottom of
the beams? From what you've
described it seems as though the maximum depth of the "pockets" isn't
more than 6" (nominal). I know
that Viking (VK468) and Tyco (TY2284 and TY2234) both have sprinklers
which can be installed at
the bottom of a beam under certain circumstances. For both models the
beam depth can be up to 14".
Now, neither of those is a concealed sprinkler, but I'd rather use them
than pocket 13-17 sprinklers in
a 224 sf room.
Just my thoughts.

I'm working on a home (13D) that has several rooms with the ceiling broken
up by "beam pockets". These vary in width from 2'8" to 3'3" o.c. with the
beams being 6" deep. Concealed residential sprinklers are being used. In
one room, which is 224 sf, if I place a sprinkler in every pocket like I
think I should, there will be 13 sprinklers. This averages out to 17 sf per
head. Another room is 375 sf and will require 10 sprinklers. This averages
at 37.5 per head. In rooms of this size do I really need a sprinkler in
every pocket? Can a sprinkler be placed in every other pocket and be
acceptable? Has anyone else found a better way to protect rooms like this?
Any and all suggestions will help.
Thanks,
