Monitor Panel in AC enclosure

I have 20 buildings with MS4 panels monitor flow and tampers installed and passed inspection in 2005.
Just had a UL audit and he says per 2010 nfpa72 chapter 10, we must monitor temp and humidity in those units , I can’t find a ref in code used in 2005 and cost to customer is almost 40k . Any thoughts if he can push to revoke UL cert

The only thing I can find in Chapter 10 is 10.14.1 and 10.14.2.4 which says that the panel must be installed in an environment within listed specifications. It says nothing about “monitoring” for temperature or humidity extremes. The way I read it, you only have to make sure the space is conditioned (heat, ventilation, etc). I would push for the specific code reference the auditor is trying to enforce.

The only other thing I can find is in 17.16.5 (basically describes a room low temperate alarm) - but that’s more for monitoring for sprinkler low temperature. And is not a “requirement” for such - that would be in 13 and 25 I would think.

Thanks for the help
