Hi Peter, I have two related questions on your response, for clarification.
First question: When you say "However, the fire alarm system can only send the proper alarm signal from a sprinkler system if the sprinkler system has a water flow switch per zone." Do you intend that to mean, "if the sprinkler system has a water flow switch per "smoke zone", or per "sprinkler zone"? Second question: When you say "Therefore, VA requires the sprinkler zones to be coincidental with the smoke zones...". Do you intend that to mean "one sprinkler zone=one smoke zone" or "one sprinkler zone= one or more smoke zones", and that the boundary of the sprinkler zone coincides with the boundary of all encompassed smoke zones. Based upon your reference to NFPA 99, "15.7.4.3.1* Where buildings are required to be subdivided into smoke compartments, fire alarm notification zones shall coincide with one or more smoke compartment boundaries or shall be in accordance with the facility fire plan.", it appears to me that the correct answer to the first question is "sprinkler zone", and the second question is "one sprinkler zone= one or more smoke zones".
