The foundation of a reliable fire detection system lies in compliance with BS 5839-1:2025, the British Standard covering the planning, design, installation, commissioning, and maintenance of fire detection and alarm systems in commercial buildings. Our expert engineers are trained and qualified to work in accordance with this standard, giving you peace of mind that your system is not only operational—but legally compliant.
In addition to BS 5839-1, there are numerous supplementary British Standards, extensions, and guidance notes that may apply depending on the nature of your premises. At MSL Fire, we stay up to date with all relevant developments, and we’re happy to advise you on the most suitable solution for your environment.
