In August, the new standard NBN S 21-100-1:2021 Fire detection and fire alarm systems - Part 1: Rules for risk analysis and needs assessment, study and design, installation, commissioning, control, use, inspection and maintenance was published. The new standard is a thorough improvement of the original NBN S 21-100-1 from six years ago. This edition is more current, even more complete and clearer. Why is this new edition worth buying? Because it is results-oriented. And also because of the addition of linear thermal detection. Further because it includes a better approach to cabling with function retention. And five notification options to suit your needs. Finally, also because the "good condition and function" approach is (finally) banished.
The new standard NBN S 21-100-1:2021 makes it possible to be truly results-oriented. This means that fire detection can be perfectly matched to objectives and risks. Risky situations sometimes require an adapted solution. In these cases, it is best to work out a customized solution with the various parties involved. This edition provides a framework for this consultation and for the final approval by the various parties involved. This framework consists of 2 elements: formulating the objectives (e.g. protection of people or goods) and the fire risk analysis. And documenting the customized solution (e.g. exceptional cases).
The standard was expanded to include installation requirements for linear thermal detection. Following wireless fire detection in the 2018 addendum, the standard this time adds installation requirements for linear thermal detectors. Thus, the new edition completes the list of explicitly described detection techniques.
The new standard and an annex with example diagrams allow a much more economical and realistic approach to cabling with function retention. And at the same time, it is fully compliant with the new "General Regulations on Electrical Installations (AREI)(Book 1)". This ensures greater clarity and a more uniform application of the regulations.
One Organisation is satisfied with a call forwarding through an intrusion system and a voice message or text message, while other organizations want to work through an alarm center. The previous standard allowed only 1 solution, while this edition describes as many as 5 solutions. Based on the results of the "risk analysis and needs assessment," you can make a conscious, informed choice.
The new edition offers numerous new and improved solutions to realize fire detection and fire alarm systems in accordance with NBN S 21-100-1 and adapted to needs and risks. Thus, there are again fewer reasons to realize fire detection systems based on "good condition and operation. After all, this approach allows for the circumvention of rules on the safety of people and property. Because legally, "good condition and operation" is a hollow concept if it is not based on a recognized rule of good practice such as an NBN standard.
For the next edition within three years, in addition to the usual improvements and clarifications, improvements include smoke and flame detection with video cameras and simplified administrative requirements for small installations.
