Electronic and physical security

UL is the leading third-party certification agency for security and signaling products and systems. A UL certification provides the quickest and surest route to product acceptance by regulatory authorities, insurers, law enforcement organizations, government, retailers and consumers.

The UL advantage

Acceptance from demand drivers -- The UL Mark is the most trusted symbol of product integrity among organizations that demand third-party certification for mission critical devices and systems.

Cooperation with government agencies -- UL works closely with the U.S. Department of Defense and Department of Homeland Security to develop the latest security standards that will affect the security and signaling industry.

Insurance industry preference -- UL certification for alarm equipment and installations are often specifically mandated by insurance companies seeking to improve their loss-to-premium ratios.

Increased marketability -- UL certification allows manufacturers to differentiate themselves from non-UL listed manufacturers, giving them the ability to sell equipment at increased margins and to customers requiring UL certification.

Technical expertise -- UL engineers are experts in the complex technology of alarm systems. UL has primary designated engineers (PDEs) dedicated to electronic security equipment.
