If I'm understanding The roof system is unchanged and your adding a lower supply to be rooms.
Use standard qr heads and same pipe sizes The roof is still most demanding Sent from my Verizon 4G LTE Droid On Apr 6, 2017 9:14 AM, Dewayne Martinez <[email protected]> wrote: NFPA 13 (07ed) I have an existing 5th floor shell space that is installed as a light hazard dry system that has pipe in the shell space and in the attic. They are turning this floor into a dormitory (R-2). 1)Can I use listed residential heads on return bends and only pick up 4 heads per 11.3.1.1 or will I need to pick up 1950SF? What if there are incidental areas such as a laundry room, ect. in the same areas as the dorm rooms? 2)What would be the required trip time be per Table 7.2.3.6.1? 15sec for residential or 60sec for light hazard?
