A fire detection system (FDS) and an evacuation alarm system (EAS) are essential fire safety installations in a building. Both systems are primarily intended to contribute to the safety of occupants. In the event of a fire, these systems provide early detection (fire alarm) and alerting (evacuation alarm), allowing people in the building to evacuate quickly and safely. In addition to personal safety, aspects such as business continuity and damage limitation can also play a role in the use of such fire safety systems, as early detection enables a faster response.
The Building Works Environment Decree, NEN 2535 (FDS), and NEN 2575 (EAS) describe the minimum requirements that the systems must meet. The demanding parties—typically the fire department, possibly supplemented by the building owner and the insurer—may impose additional requirements in certain cases. These requirements are recorded in the Performance Requirements Document (PvE). The PvE is approved by the demanding parties and serves as the basis for the system’s implementation.
We prepare the Performance Requirements Document for you. Since we do not install the systems ourselves, independent advice is guaranteed. In a PvE, all requirements for an FDS and EAS are clearly and consistently documented, preventing discussions during the implementation phase about the correct execution of the systems.
In buildings where large numbers of people may be present, a type A system is often used. In the event of an emergency, this system broadcasts a spoken message to initiate evacuation quickly. This is known as a “voice alarm” system. In large, hard-surfaced spaces, the speech intelligibility of such systems can be very poor due to strong reverberation. Think of airports, train stations, and stadiums. Through measurements, calculations, and experience, we help shape the system design to ensure optimal speech intelligibility.
