Scot, I responded to the specific question (and assumed everyone understood the 30% increase would be applied to the roof/ceiling). However, I would not recommend a dry system in-rack if you can avoid it. Quell, preaction, other might be better if possible. Also, an engineered solution where you calculate the delivery time to the in-rack sprinklers might be part of the solution. No one has asked what the hazard is, the specifics, or why the dry system...

If a mitigation is warranted, I would rather see that mitigation shorten the required water deliver time, than try to place catch up with more sprinklers. scot deal excelsior fire -------------- next part -------------- An HTML attachment was scrubbed...
