Hello everybody.

I was wondering is there any chances to make a big fire (like 10x10m) and add one sprinkler in the middle to see the extinguishing area of sprinkler using a temperature slice ?  If someone already tried something like that please share your opinion.

The short answer is no.

By "one big fire" do you mean a burner? A sprinkler will have no effect upon a default burner, or surface, for that matter. If you put in a value for the extinguishing coefficient (E_COEFFICIENT), then the sprinkler will influence the burner, and may in fact put it out.

The problem is that nobody knows the values for extinguishing coefficient. (Read about it in the FDS Users Guide)
