During a phone call with the F/A contractor today I was told it was "illegal" to put it in the electric room.
Why in the world every specialist contractor wants his own mechanical room still confounds me. This is all I can find on the matter. I'm pretty sure NFPA 72 is another one of the one's that's free to read online.
