UL Mandates Marks to be Placed on Approved Security Products


UL has announced it is introducing marks that will be
placed upon security and signaling products that have been
tested and evaluated to UL standards. The three “Security
and Signaling Marks” will need to be implemented and put
on products that are UL approved by May 1, 2007.

manufacturers with a clear distinction and marketing
advantage from competitive products that have not been
evaluated for their performance in these specific
applications,” said Chris Hasbrook, general manager of the
UL Fire, Safety & Security and Environmental Services
SBU. “Millions of individuals and businesses depend on
automated systems and devices for protection from fire and

    and life-safety alarms. Typical products in this category
    are smoke detectors, fire alarms and hospital nurse call

  • Security Mark: Applies to products such as
    intrusion detectors, burglar alarms, access controls, anti-
    theft alarms, surveillance systems, safes and vaults.

  • Combination Security and Signaling Mark: Applies to
    products that serve both security and signaling functions.
    A typical example is a combination fire and burglar alarm
    system. Such products are evaluated for both
