Dear forum members, While attending Cecil's recent hydraulic calculation seminar (Awesome!), I was reminded of the allowance for the remote area reduction for high temperature sprinklers in extra hazard occupancies.
I have a project with a specification for ordinary temperature sprinklers for an extra hazard area. I plan on submitting an RFI to the project engineer to see if the area could be reduced using high temperature sprinklers. In order to make everyone feel warm and fuzzy about the reduction I was hoping to get some background on how the reduction for high temperature sprinklers came about. My theory is that the original area densities were derived from initial testing with Ordinary temperature sprinklers and that some years latter testing with high temperature sprinklers indicated that the effectiveness of the higher temperature sprinklers was superior. Can anyone confirm/dismiss this theory or provide any other insight on this reduction? (year of testing/who performed testing, etc) As always thank you very much for your insight! And thank you Cecil for the numerous nuggets of info in the seminar!
