Fire Area Calculation

[Saber Elkassas]

Hello,

I have a building with a garage in the ground and 1st which shall be required to have an automatic sprinkler system and the upper two floor are not required to have a sprinkler system. they have only a common staircase that opens to outside at the ground level. Can I consider these two floor separate fire area from the garage fire area to omit the sprinkler installation in these two floors?

We would need much more info to really determine, but you can separate fire areas with fire barriers at times to avoid sprinklers...
