Alarme intrusion 
Protégez ce qui compte 
réellement pour vous

Il ne suffit pas d’installer quelques détecteurs au hasard pour se croire protégé. Une installation conforme à la norme NBN S21-100 est essentielle pour garantir une détection efficace, limiter les risques et assurer la protection des occupants.


Chez EWE, nous vous accompagnons avec rigueur et méthode.

Nous concevons des systèmes conformes, adaptés à votre environnement, installés dans les règles de l’art et pensés pour durer.

What is the NBN S21-100 standard?

The NBN S21-100 standard is the reference framework in Belgium for installing reliable and effective fire detection systems designed to truly protect buildings. It exists for a simple reason: to ensure that if a fire breaks out, the detectors respond quickly. And that the alarm gives everyone time to exit the buildings. And to get to safety.


This standard applies to several types of buildings: businesses, apartment buildings, schools, hospitals, offices…

Why trust EWE?

 Pourquoi est-elle si importante ?

Because complying with the NBN S21-100 standard is not just about "doing things by the book." It’s about ensuring that if a fire breaks out, your system reacts appropriately. And most importantly, in time.

  • Your detectors trigger the alert quickly.
  • The installation meets the expectations of firefighters and insurers — which avoids many complications in the event of an inspection or disaster.
  • And above all, the people on site are better protected. Less risk. Less damage.


On the contrary, ignoring this standard is playing with fire.


Detectors that react too late. Unreliable alarms. Insurance that refuses to pay out... The consequences can be severe.

Better to start on a solid foundation right away.

What does the standard say about the installation of detectors?

A fire detection system only works properly if everything is well thought out. The NBN S21-100 standard is based on three main principles:

🔹 A good location.

Detectors are not placed just anywhere. Their position is essential for quickly detecting smoke and flames.

Misplaced, they may react too late — or not at all.

🔹 Certified equipment.

No way to install just any detector. The standard requires the use of compliant, tested, and reliable equipment.

It is what ensures the system's performance, day after day.

🔹 A follow-up interview.

Even the best detectors must be checked. The standard provides for regular inspections and tests to ensure that everything works in case of need...
