communicating spaces are fed from a wet system. Do I include the sprinkelrs in
the communicating spaces, even though they are off different
The Connecticut Fire Safety Code (at least the part that is based on the IFC)

See NFPA 20 2003 for first invocation against using the main
Yes. If a fire will activate the heads in the communicating space if they
were off the same dry system, they will also activate the heads on the wet
system.
