60 different references of smoke alarm devices have been tested in the frame of market surveillance processes from several countries. The samples have been tested at ANPI according to EN14604 for 6 requirements: battery removal indication, marking and data, directional dependence, initial sensitivity, fire sensitivity, and sound output.
The results have been statistically analysed along 2 axes: requirements and claimed certification scheme. The results provide the occurrence of noncompliances to the requirements. It appears that 33% of the sampled products are not compliant for at least 1 requirement, that 19% of the products have a problem with fire detection, that products which claim at least one voluntary mark certification yield significant better results by a factor 2 to 4 than these claiming CE only.
