This is difficult to explain but...
Upstairs hallway that is 8ft in length. Two bedrooms and the staircase going down is inside the hallway.
There is a single smoke detector that is aprox 6 ft from the bedroom doors and 2ft from the edge of the wall where the staircase is...
The inspector is failing us because he says that the smoke detector that is 2ft away from the wall of the staircase is servicing the bedrooms therfore can't service the top of the stairs requirement.
He is reasoning this because there is a air supply vent 3 feet away from the smoke that is sitting over top of the stairs. The supply vent blows the air away from the hallway therfore it would blow any smoke away from the smoke detector so it doesn't count.
What does this guy expect, a smoke that will be directly overtop of the landing at hte staircase?
I challenged him on this and he looked at the NEC for bout 15 minutes after saying "Well here it says that it is required to have a smoke that is in accordance with 902.5 in the NFPA 5.0 and I am failing based on NFPA 5.0 902.5".
