Russell,
Just one more thing that I wanted to come back to, and that is the fire shutters that you mentioned earlier.
As I mentioned earlier, my partner is a fire captain with many years of experience, and I've just finished talking to him about this. He says that he has never - ever - seen or heard of fire shutters being installed in elevator hoistways.
I have 13 years of experience in specifying fire dampers, and I have never once put them in an eleveator shaft, nor have I ever seen an existing condition of a fire damper installed in a elevator shaft.
LashL, fire dampers are installed in either air ducts or air transfer grilles. The only openings in elevator shafts are for the doorways.
