And so???? Response time difference is only one factor to consider. Many would draw the conclusion 'OMG 100 seconds difference but what about the children'. Just because the first sprinkler operates later has NO direct singular correlation to the outcome. This is WHY we use higher temperature heads in high heat release heat fires - in order to keep the wet stuff on the red stuff (or at least real close factoring in plume dynamics). So the potential here is possibly BETTER fire protection performance because although delayed fewer heads operate thus more water where it's needed. Be careful in drawing any conclusions when only doing part of an analysis.
I realize you are not intending your FDS model to be the conclusion of this discussion but you, Ron and I are not the only ones reading this forum. (PS anyone know how many subscribers these days?)
