Is there a requirement for it to be UL listed or to meet the UL specs?
What Is the Difference Between ETL Listed and UL Listed? - Alarm Grid
If a product is UL listed or ETL listed, then it has been tested and approved by a Nationally Recognized Testing Laboratory. Learn about being ETL Listed versus UL Listed.

"In the United States, all Nationally Recognized Testing Laboratories (NRTLs) are required to follow the same testing procedures and maintain identical standards. Whether a product is tested and approved by ETL, UL, or any other NRTL makes no difference with regard to the standards it is required to meet."
If the product is marked by a recognized NRTL saying it has met UL 1741, then that is as good as being "UL Listed" for the purposes of code and regulatory compliance.
We should stop using the term "UL Listed" and instead use the term "Certified to UL Standards".
Here is a lit of NRTL:
If "UL Listed" was actually required, that would be granting a monopoly to company in the field of product approval. I am pleased this is not the case.
