You are not required to include them. From the 2013 ed. 23.4.4.6.3 The requirements of 23.4.4.6.1.1 to include every sprinkler in the design area shall not apply where spray sprinklers or CMSA sprinklers are provided above and below obstructions such as wide ducts or tables.

Are standard spray sprinklers located under obstructions greater than 4' required to be included in calculations? I seem to remember, no they are not, however the reference in the standard is eluding me.
