The critical question has been answered - that being the compressor
does not need to be Listed. I should say for Fire Protection use.
When a listing is required, it does have to be for Fire Protection
verses the slew of other listings available (often for electrical
safety as likely performed on your compressor).

AHJ is not satisfied with UL listing on a tank air compressor bought
from a local hardware store. As I read the NFPA 13 3.2.3. concerning
equipment listing, it shall be "listed". This air compressor
performs as it should; however it is not listed for fire sprinkler
use, as per AHJ. So my question is this are nitrogen bottles listed
for fire sprinkler use as well as their regulators and hoses? Are
all shop air compressors listed for fire sprinkler use that we tap
into? The UL listing on any air compressor is valid? I didnt feel
confident enough to challenge the AHJ (Local Fire Captain)
concerning these questions or my interpation of codes. So what will
the forum say?
Thank you for any input
Justin
