Distance from HSW sprinkler to ventilation outlets in an apartment?

I have a question regarding the distance from the hsw sprinkler to a ventilation outlet that is placed about 25mm from the sprinkler head. The sprinkler deflector is not obstructed by the ventilation. But my concern is that the air will cool the sprinkler so much that the sprinkler activation will be delayed. Is this ok? I can't find anything regarding this in the NFPA 13. 

I hope that someone can help me find anything regarding this and hopefully point to the right NFPA 13 rule point.

Best Regards
