ESFR Sprinklers and the issue of ceiling batt insulation

[SprinklerDesigner2]

Building is bar joist with 3" batt insulation so it looks like NFPA #13 2013 Edition EXHIBIT 8.11 Sprinkler Positioning Under Roof Insulation found on page 285 of the handbook.

So using a standard upright or pendent sprinkler I can position the deflector up to 13 1/2" below the roof deck assuming we have 3" batt insulation. While the Exhibit shows only an upright sprinkler I have to think this would apply to a pendent as well.

But the building I have has an ESFR system using K16.8 pendent sprinklers where the deflector must be no more than 14" below the ceiling.

I would really like to have that extra 1 1/2" does the batt insulation situation apply to ESFR sprinklers as well?

At first I thought it would apply but the more I think about it it probably doesn't. Darn!

Thoughts or extra knowledge, anyone?

Thanks.

It seems it applies. Par. 8.5.1.3 says that all requirements in 8.5.2 through 8.5.7 shall apply to all sprinkler types. That would include ESFR. The batt insulation requirement falls under 8.5.4.1.3.2. The commentary also states

The general requirements with which all sprinklers must comply are covered in Section 8.5.\

Further, first sentence in 8.12 (ESFR requirements) states

All requirements of Section 8.5 shall apply except as modified in Section 8.12.
but ESFR requirements do not address anything about insulation or roof deflection etc.

My understanding is that you will need to satisfy both requirements.
