Rick:

If the AHJ would read the direct code, it would be apparent that the
"Dedicated Space" is not defined by floors walls and ceiling, but by the
amount of space required around above and in front of electrical equipment,
If this is less than the total room, then there is room to run all of those
other systems in and out of the electrical space/room in that area other
than the zone. As I've said before there is a very good drawing of this in
the handbook.

Subject: RE: Electrical Rooms

Craig,
See NFPA-70, Article 110.26 (I) (a) for Indoor Installations.
This describes the 'dedicated electrical space'. 
"No piping, ducts, leak protection apparatus, or other equipment foreign to
the electrical installation shall be located in this zone".

Some AHJ's interpret this section to say that the sprinkler piping is
allowed to end in the room, but the piping passing thru the room to another
area is "foreign" to the electrical installation. Ask your AHJ what is his
interpretation of this.

There is also a subsection (c) which allows sprinkler protection in the
dedicated space provided it complies with the section.
