How UL Certification Benefits Commercial Security Systems
Since 1894, Underwriter Laboratories has worked to ensure the safety of consumer-ready products. From industrial equipment to home appliances, all UL-Certified products must pass rigorous tests and meet nationally recognized safety standards. Continual checks ensure the products remain sustainable and safe. Additionally, UL sets industry-wide standards to certify facilities, systems or processes that manufacture and install new products. UL-Listed companies meet all local and federal environmental regulations, too.
While UL Certification is optional, many companies have started to design products with the UL Mark in mind. Some have even taken steps to become UL-Listed Services themselves. So, what makes UL Certification attractive for both companies and consumers?
UL Certification ensures new products have high-quality manufacturing and installation — allowing companies to establish best safety practices and inspire trust in their consumers. To become UL Listed, a company must design products that meet UL's standards and demonstrate consistent adherence to relevant codes. Being UL Listed authorizes manufacturers to apply the UL Mark on self-tested products. The UL Certification also expresses confidence in a product's quality and adds accountability for consumers.
Consumers want to know that their equipment or appliances meet or exceed safety and sustainability standards. UL-Marked products and UL-Listed companies give consumers peace of mind about the products they buy. Being UL Certified is a powerful marketing tool that most consumers value.
Knight Security Systems is proud to be among only 2% of UL-Listed security companies nationwide. We test and certify all commercial security systems installed in the Long Island area. We also have the authorization to issue UL Certificates of Compliance for our installations. Knight Security Systems prioritizes consumer safety, providing security systems that meet the regulations.
