Dan,
That is almost exactly what was tested. The concern was that the upright
would operate first and prevent the pendant from operating. It operated
first, but the pendant operated almost immediately after it. It makes a
good solution for obstruction problems in existing systems, but the 35
ft. height limitation can be a deal killer.

If there is no problem of mismatch,
Then what about the difference in clearance between the two types.
In one particular case I found the upright at 5in and the pendent at 14in
clearance, next to each other.

Subject: Re: Mismatch of upright and pendent sprinklers
No restrictions that I am aware of.
If memory serves me right, FM made an earlier statement that
localized upright ESFR sprinklers could be used within an otherwise
pendent ESFR system. That had to break the heart of the mfg that
developed the first upright (since they are far superior in regard to
obstructions).
Joe - any comments?

Dear All,
What is your opinion regarding the use of upright and pendent ESFR
sprinklers in the same area?
What about mixing brands of different manufacturers?
