Looking at installing a cable tray that runs the length of the room in an Ordinary Hazard Occupancy.
The cable tray is about 2-feet wide and the sprinklers are standard uprights. The cable tray is less than 18-inches below the sprinkler.
However, the cable tray may be centered directly below some sprinklers, but off to the side for other sprinklers.
What obstruction criteria from NFPA 13 (2016 Edition) would apply?
Three Times Rule (Section 18.104.22.168.1.3)?
If Three Time Rule applies, is that measured vertically, horizontally, diagonally, or all?
Thanks in advance.
