This issue has caused a lot of inappropriate zoning layouts. The
alarm section of the IBC (907) is stating that you have to include
the water switch as a zone BUT it does not dictate the number and
size of the sprinkler zones. That is driven by the sprinkler section
of the IBC (903).
There are other code sections that support this so don't read just
this one section and place too much emphasis on the AND pushing all
the other requirement of 907 onto the sprinkler system.

This is due to the use of the word "AND" in the following line. If
the word
was "OR" I would be on your side of the fence.
"Alarm initiating devices" are given as "heat detectors,
waterflow switches and manual stations".
