Concrete Tee vs Slab on PC Prestressed Joist Construction

Discussion created by awilliams on Nov 28, 2016

For the purpose of interpreting NFPA 13 - Obstructed Construction, can Slab on PC Pre-stressed Joist construction be considered as similar to Concrete Tee construction? Can the sprinkler be installed with the deflector located at or above a horizontal plane 1" below the bottom of the joist regardless of the depth of the joist?
