BS 5839 is the British Standard that governs the design, installation, commissioning, and maintenance of fire detection and alarm systems in non-domestic buildings. It plays a vital role in ensuring safety and compliance across commercial, industrial, and public-sector properties.The most recent update to this standard introduces several key changes that have implications for both fire system installers and building managers.
So, what does this mean for you?
1. Greater Focus on False Alarm Management:
The updated standard puts increased emphasis on reducing false alarms. These unwanted signals can be disruptive, costly, and even dangerous if they cause complacency. New systems must now be designed with measures in place to minimise false alarms, such as:
- Improved detector placement
- Intelligent multi-sensor use
- Appropriate system programming and configuration
2. Enhanced Detection in Voids
There is now clearer and stronger guidance on the need for smoke detection in ceiling voids, underfloor areas, and other concealed spaces where a fire could develop without being noticed. Buildings with hidden or complex layouts may require a system review to ensure compliance.
3. Clarity on Multi-Sensor Devices
The revised guidance offers updated recommendations on the use of multi-sensor detectors. If your existing system uses these types of detectors, a professional review may be necessary to confirm they meet the new requirements.
4. Improved Documentation and Zone Plans
BS 5839 now places greater importance on clear documentation. This includes:
- Up-to-date zone plans displayed near control panels
- Accurate commissioning records and maintenance logs
- Readily available user instructions and system documentation
Failing to maintain this documentation could lead to non-compliance during inspections or audits.

What are the latest updates to BS 5839?
The latest BS 5839 updates clarify system categories, inspection routines, and documentation requirements. They emphasise improved reliability, clearer design standards, and stronger alignment with the Regulatory Reform (Fire Safety) Order 2005. These updates affect how fire alarms are installed, tested, and maintained
Does BS 5839 apply to all buildings?
BS 5839 applies to most commercial, industrial, institutional and public buildings in the UK. Different sections of the standard (such as Part 1 or Part 6) apply depending on building use, occupancy type, and fire risk category.
How do I know if my system complies with the latest BS 5839 standard?
To confirm compliance, you should have a certified fire safety contractor carry out an audit of your system design, installation, and maintenance records. They can assess whether your current setup meets the latest BS 5839 requirements and recommend necessary upgrades.
