Compliant fire system installations with all the advanced features that come with them rely on the power supply! It goes without saying that specifying a high-quality PSU built for reliability and longevity is the obvious choice. Elmdene's STX range of EN54-4 approved power supplies have been specifically designed for Fire System Installations and features intelligent battery charging and monitoring with remote fault signalling.

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's STX range has been evaluated and tested by an independent, third-party notified body. 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 European technical standards ratified by one of the three European standards organisations.  To test and evaluate components and products that allow a certification mark to be placed by the manufacturer. Compliance with these standards ensures that the STX range operates reliably and illustrates Elmdene's dedication to safety and quality as a manufacturer.

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.
