Summary of EN 54 and NF standards

The purpose of a fire safety system is to contribute to the safety of people and, subsequently, to that of property in establishments receiving public (ERP). To achieve this, it is essential to evacuate a building first.

In addition to preserving the inhabitants from the disaster, the evacuation has the advantage of leaving the place free for the emergency services. This is why buildings must be equipped with evacuation systems.

These systems are called Alarm Systems (AS). There are several types of AE, including the safety sound systems (SSS), defined by the text NFS 61-936, and which is applied according to the type of ERP.

The evacuation sound is regulated, in France, by the NFS 32001 standard which defines its acoustic characteristics. In addition to this specific sound, a spoken message and/or a visual signal can be added.
