Sounds like they're asking for a vestibule or some sort of enclosure, but I'm not going to speculate. Are you asking this in the context of fire sprinkler protection or general building code requirements?

Separating the two areas into separate fire areas was reviewed and ultimately approved by City of Kirkland as the means to achieve this scope. They have interpreted that if we separate the spaces into different fire areas, the fire alarm will need to be separated and are asking if the fire sprinkler system also needs to be separate. Any ideas? I don't think the fire sprinkler system needs to be separated but they are asking me to confirm.

You are describing a situation that requires opening protection because of the floor-to-floor penetration, which in and of itself doesn't create a separate "fire area" but does communicate between different floors. If you end up placing a water curtain around the opening at the lower level, it should be supplied by the floor control assembly for that floor. The market above is supplied by its floor control assembly. Hope that I'm understanding your question, Steve L.

The Architect is now saying that it needs to be rated and is asking if since there will now be two separate fire areas does the fire sprinkler system need to be separated along with the fire alarm system? I cant find anything in the IBC that clearly states one system is acceptable or that two separate systems are required. Anyone have any thoughts on this?
