Hey All, I have a combustible concealed space (ceiling cavity) that doesn't meet any of the requirements of 8.15.1 THRU 8.15.1.2.17 for omitting sprinkler heads from this area. My question is two part:
- Can I leave the space unsprinklered if I increase the Density Area to 3000 sq.ft for the room area below the ceiling?
Any clarifying thoughts are greatly appreciated. Thanks!
- Can I leave the space unsprinklered if I increase the Density Area to 3000 sq.ft for the room area below the ceiling?
- This would essentially over water the room area below the unsprinklered ceiling cavity but would not provide protection if a fire was to start inside the ceiling cavity.
- Do I have to have to increase the Density Area to 3000 sq.ft for the room area below the ceiling if I sprinkler the interstitial ceiling cavity?- My thoughts would be, why would I have to increase the Density Area below the ceiling if I'm already sprinklering the cavity space.
Any clarifying thoughts are greatly appreciated. Thanks!
