Security & Signaling Marks

Marking Requirements for Security & Signaling Equipment

Some product categories will require a change to both the Mark and a simplified product identification as part of the Listing Mark. Other product categories will require only a change in the Mark. And some may not require any changes. When there is a simplified product identification required as part of the Listing Mark then additional use markings will also be required elsewhere on the product or they may be included on the same label as part of the Listing Mark.

To determine the marking requirements for your product you will need to know the CCN. You can locate the CCN on the Authorization page in the UL Procedure file that describes your product. The CCN can then be used to identify the appropriate Listing Mark information and supplemental marking information located in the marking table.
