NBN S 21-100-1:2021

Fire detection and fire alarm systems: Part 1: Requirements for risk analysis and needs assessment, planning and design, installation, commissioning, control, operation, testing and maintenance

Expected to be published in October 2021, the NBN S 21-100-1:2021 standard was finally published on 16 August 2021 thanks to the dynamism of its working group NWI (New Work Items, in which ANPI participates).
Given the extent of the changes, it is no longer an addendum, but a fully revised coordinated edition applicable to any project.

This new edition bans once and for all the disastrous "good functioning" approach of circumventing the rules in the field of safety of people and goods. This irresponsible approach can lead, in the event of a disaster, to the owners and the project manager being held responsible without them being specifically aware of it.    
The standard proposes a results-oriented performance approach, which is essential for the design and implementation of automatic fire detection systems that are perfectly adapted to the needs, objectives and risks.
In addition, the application of innovative fire detection solutions is now greatly facilitated.

The whole text has been corrected, completed, improved and made more user-friendly...

Some six years after the publication of NBN S 21-100-1:2015 and three years after Addendum 1, the standardisation committee SA/E072 is offering a completely revised edition that meets all the needs in the field of automatic fire detection.

Here are some arguments to convince you to quickly go to the NBN website and acquire this new edition:

  • the performance and results-oriented approach ;
  • the addition of installation rules for linear thermal detection;
  • an approach that allows for a much more economical and realistic approach to retention of function cabling, while at the same time being fully compliant with the new "General Regulations on Electrical Installations - Book 1";
  • a chapter on "exceptions" which makes this standard the generic reference for any project in this field and puts an end to false excuses for not applying it;
  • numerous adjustments throughout the text to improve clarity.

The next meeting will be in three years' time, when the many issues still on the table of the NWI working group will be put into practice, such as smoke and flame detection by video camera, simplified administrative requirements for small installations, ...
