UL listed, it’s a term we hear often and trust that it must mean products are tested and approved by some sort of authenticating body, but do we really know what it means?
What Does UL Listed Mean?
Underwriters Laboratories, UL, is a company that is approved by the U.S. Occupational Safety and Health Administration, OSHA, to perform safety testing on various products and new technologies over a wide range of industries. UL is headquartered in Illinois, although maintains offices in 46 countries and provides more than 1,500 global safety certification standards.
The UL certificate is a declaration by fire alarm companies that the system is in compliance with applicable standards and codes.
History of Underwriters Laboratories
UL was founded by William Henry Merrill in 1894, a 25-year-old electrical engineer from Boston. He started his career investigating and assessing risk for underwriters issuing fire insurance. He realized a potential for standardized testing on building materials and founded Underwriters Laboratories in Chicago. Merrill and UL quickly began developing standards, designing and testing equipment and identifying hazards.
Merrill also served as the Secretary/Treasurer for the National Fire Protection Association, NFPA, from 1903 to 1909 and was the President from 1910 to 1912. UL shares a mission with companies and stakeholders for more secure, safer and sustainable world. UL is committed to progressing Sustainable Development Goals and is signatory to the United Nations Global Compact to uphold principles of responsible business.
UL Listed for Fire & Life Safety Equipment
All UL listed fire alarm and life safety equipment includes a UL listing mark on the product or the container in which the product is packaged which includes the word SIGNALING located above the UL symbol and LISTED located underneath the symbol with a control number and product name. This is applicable to all fire alarm and signaling equipment including:
- Power supplies
- Fire alarm control panels
- Individual components
- Modules
- Relays
- Devices in the field
One critical distinction is to note that there are different listings for Fire Alarm Equipment and Fire Alarm Subassembly.
UL listed visual and audible signaling devices meet safety and quality standards aligned with fire and life safety technology and advancements. UL listed visual and audible signaling devices help clients and safety system integrators mitigate risks and provide an appropriate standard of care to asset owners. UL listed fire alarm signaling devices validate code compliance and provide assurances that your system will undoubtedly help to save lives and properties.
