6.8.5 13R 2002 If it's not fuel-fired I know it doesn't say A/C closet with 4" annular space. Is the hazard greater than Penthouse equipment rooms, Elevator machine rooms.
If the AHJ says yes to that good luck!

The heads that are approved for this condition are no different than the heads that you have installed. Besides the section I already gave you (6.8.1.5.3.1) there is another that is applicable - the 'shadow' rule - 6.7.7.1.5.7 - it sounds like what you have meets this also. In addition, if your mech room does not have a door but merely an access panel the head is not even required unless it is a gas-fired unit. (6.9.6) All of these are from the 2007. I don't have the 2002 handy. Hope something helps with this situation!

It is a 13R building under 2002. He didn't allow the exception because the closet ceiling is greater than 5 ft (Actual 8ft). Still negotiating.
