Entire fire systems with all the advanced features that come with them rely on the power supply! So it goes without saying that insisting on a high-quality PSU built for reliability and longevity is the obvious choice.

EN54 is a mandatory fire detection and alarm system standard and refers to compliant power supply equipment for fire detection and fire alarm systems.

To comply with EN54-4 (the power supply component), Elmdene products are evaluated and tested by an independent, 3rd party notified body. This testing includes battery charge/discharge profile assessments, a wide range of functional tests, extensive environmental testing, and extremely thorough EMC testing.

EN standards are highly credible. EN refers to technical European standards, ratified by one of the three European standards organisations. UL refers to US standards. Underwriters' Laboratories (UL) test and evaluate components and products that allow a certification mark to be placed by the manufacturer. Compliance with these standards ensure products operate reliably and illustrate a manufacturer's dedication to safety and quality.

These certifications are very important as they assure you that an objective, regulated third party has vetted and rigorously tested products according to the same standards (the same level playing field). So overall, it's essential for the power supply product to be certified by third-party testers.

Be conscious of manufacturers who claim EN or UL but do not comply with these standards. Compliance with these standards ensure products operate reliably and illustrate a manufacturer's dedication to safety and quality. Product costs often reflect the highest quality testing, offering peace of mind when installing critical systems.
