FAQ
FAQ
What is NF Certification and why is it important for a smoke detector?
NF Certification (Norme Française) is a French quality mark issued by AFNOR. For smoke detectors, it guarantees that the device has been tested by an independent body and complies with the strictest French and European safety and performance standards (going beyond the basic CE mark). It is a sign of superior reliability and durability.
Is NF Certification mandatory in France?
While CE certification is mandatory at the European level, only the NF mark officially certifies that the detector fully complies with the specific French decree [Reference date of the law, often 2011/2015] regarding the specific quality and installation requirements for smoke detectors in homes. It is highly recommended by insurance companies and fire departments.
What performance aspects does NF Certification guarantee?
It specifically guarantees the reliability of detection (ability to detect different types of smoke), the quality of the audible signal (sufficient volume of 85 dB at 3 meters), resistance to shocks and temperature variations, and the longevity of the integrated batteries/piles.
Is the detector easy to install despite the NF requirements?
Yes. NF certification applies to performance and manufacturing quality, not the complexity of installation. Our NF-certified detectors are designed for simple and quick installation while meeting all safety criteria.
Does this certification have an expiration date?
NF certification is a continuous mark, but it is linked to the product's recommended lifespan. An NF-certified detector is designed to provide reliable performance throughout its entire recommended lifespan (often 10 years), provided adequate maintenance is performed.
