Question asked by ngrpe3 on Mar 22, 2017

I have an existing warehouse with a wet system ESFR k16.8 sprinklers. The high point of the building is 40'71/2"

Racks are going in aprox 40% of the building. NFPA table calls for in-rack sprinklers to be installed.

Can I change the sprinklers over the racks where the ceiling is over 40' to k22.4 or k25.2 sprinklers so as not be required to install in rack sprinklers. If so do I have to install a water curtain around the area ?
