True and thank you for clarifying that; however, the examples I cited
are all only applicable to NFPA 13 systems in the 2006 edition we
enforce if the table I referred to is accurate.
The table I used is Figure 903.3.1.1(2), "Examples of Requirements
Modified Through Use of Automatic Sprinkler S

changing a few cycles ago. In R occupancies, many trade-offs can be
applied with a 13R system. Also careful on "provided throughout"

You're correct Ron. Biggest reasons for not sprinklering is either fear of
accidental head discharge and/or electrocution from the accidental head
discharge. Neither can be substantiated through verifiable statistics.

once had an electrical engineer tell me you couldn't sprinkler a

It makes no difference whether the line passes through the room or comes in and
stops as long as you are in the allowable space as defined within the section
