Smoke alarms are subject to the Building Products Regulation, so they must comply with the EU standard EN 14604. Documented by an independent notified body such as VdS. Unfortunately, since 2013 it is up to each manufacturer to decide which individual standard requirements the product should and should not fulfil. This means that detectors can come onto the market that have been tested for immunity to interference, but not for the decisive detection function. At the same time, the building regulations of the 16 German federal states require the fulfilment of certain points of EN 14604.
This leads to the following absurd situation:
Whether a detector bearing a CE mark may be sold at all in a German federal state can only be determined by comparing the manufacturer's declaration of performance with the respective state building regulations. A demanding task, which even experts sometimes fail to perform, is often assigned to dealers who are not experts in the field.
With a VdS-approval it is always ensured at first glance that all requirements of EN 14604 are fulfilled. There are no restrictions whatsoever on use in Germany, Europe and many other countries that are based on the EN - your sales activities are thus made considerably easier, also thanks to the well-known market strength of VdS-approval, This is because with a VdS-approved smoke detector, end users can rely on dependable, life-saving products to protect their lives in an emergency - and manufacturers, bulk buyers and rental companies can be sure that all legal requirements they have to prove are met.
