The building code requires that high-rise sprinkler systems be controlled and the waterflow/tamper alarms be annunciated per floor, but not fire area on a given floor. 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. From: Anthony Carrizosa <[email protected]> Sent: Tuesday, July 26, 2022 8:33 AM To: [email protected] Subject: [Sprinklerforum] Do separate fire areas require sprinkler system to be separated We are working on a high rise building were the below grade parking has a grocery store above on the grade floor, an escalator/stairs provides access between the garage and the store and has a non-rated enclosure around it. 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?
