I'm laying out the fire sprinklers for a building where the architect has used the IBC exception in Section 403.2.1.2 that requires sprinklers to be installed at the top and alternating floor levels of a vertical shaft. This reduces the required shaft enclosure to be 1-hour for highrises up to 420 feet.
NFPA 13 doesn't seem to address this specific arrangement. I've looked and I'm not finding any installation requirements. I have concerns with just putting sprinklers in the shaft.
What's the best type of sprinkler for this?
Should they have water shields?
Should I have concerns for obstructions?
Any guidance would be greatly appreciated, thanks in advance.
