Does air handler room need to be protected or fire resistance for the wall are enough? In our case, there are AHU rooms in all 4 floors of the building. The rooms are only for AHU.
If the building has a full NFPA 13 system
Than normally yes.
We need to provide fire fighting or no. If not needed, kindly provide the reference
Yes it is required per NFPA 13,
Fire sprinkler through out.
Unless Per NFPA 13, there is an exception.
Without seeing plans or the job, that is the best call.
I would be happy to give you the code references if you would answer a few questions.
Please answer and you will get some expert help.
