Security & Signaling

Show the market that your product has been tested for security and signaling performance

On May 1, 2005 UL launched it’s new Security & Signaling Marks. UL is now introducing a simplified product identification for many of the Security & Signaling product categories. This simplified product identification along with the new Marks, the word “LISTED” and a control number, comprise the UL Listing Mark that identifies products covered under UL’s Security and Signaling requirements. UL Listing Marks with the new Marks and simplified product identification are currently optional, but will be required after December 31, 2008.

Questions regarding the Listing Mark, control numbers and label layout approvals should be directed to a UL Label Center. All other inquiries should be directed to:
