E.S.F.R. obstructed line

I have a warehouse with a concrete structure.
In ceiling, the beams create a continuous obstruction of 320 mm. The distance between beams is 1500 mm.

 

I want to install sprinklers E.S.F.R. According to NFPA 8.4.6.3.1 if I have more than 300 mm of obstruction. I have to install a sprinkler line in each bay.

 

The distance between lines of sprinklers will be 1500 mm. If I install the sprinklers less than 320 mm from the ceiling. I have to comply with the minimum distance between sprinklers of 2400 mm.

 

When the sprinklers are inside each bay, should I meet the minimum distance?

 

For the calculation I have to take into account the operation of 12 sprinklers or more?

 

If I install the E.S.F.R. 400 mm from the ceiling. I could install E.S.F.R. with this 320 mm obstruction?
