Technical Standard

EN 14604 & DIN 14676 – Manufacturing Standards for Modern Smoke Detectors

Manufacturing standard

DIN EN 14604 is a manufacturing standard which applies to companies that manufacture smoke detectors and then sell them on the EU market. The Pyrexx smoke detectors with the Magnetic Gel Pad installation technique fulfil the requirements of DIN EN 14604.

Although DIN EN 14604 defines, for example, the colour of the warning lights, assuming the manufacturer decides to fit their product which such a feature, it does not in any specific way define they type of fixing for a smoke detector. This standard does not set down particular screws and screw plugs as the means of fixing, but very generally uses the term “means of fixing”. This is also the correct approach, as the choice of fixing for a smoke detector is ultimately dependent upon the type of surface where the detector is to be installed. As part of the standard's impact test, the smoke detector must remain affixed in its installation location when the body of the device is hit from the side with a pre-defined force. Although this impact test cannot replicate the actual diversity of different installation locations and also does not define a particular means of fixing, Pyrexx GmbH has had the Magnetic Gel PaD installation method tested by TüV using the impact test contained in DIN EN 14604 for resistance to this defined lateral impact test. The Magnetic Gel Pad fixing technique passed the test with ease.

Application standard

DIN 14676 is an application standard and for the operator it governs what types of detector are to be installed and where, and in what way the maintenance of the devices is to take place. In terms of quality, the maintenance service at Pyrexx GmbH exceeds the requirements of DIN 14676 by a long way. DIN 14676 should be viewed as an instrument which documents the best available technology for the user in regard to the installation location and the maintenance operations. At the centre of DIN 14676 is an obligatory annual visual inspection. Currently, no remote maintenance inspections conform to DIN standards.


The TÜV NORD Group has joined forces with the KRIWAN test centre to create a new and uniquely transparent quality label. The TüV-Kriwan quality label is awarded to quality smoke alarms which fulfil even stricter criteria than the DIN EN 14604. It is designed so that it is possible to recognise straight away what quality features the smoke alarm possesses. Smoke alarms which carry the TüV-Kriwan quality label fulfil important test criteria in accordance with the fire alarm standard EN 54 part 7: smoke alarms – a circular detector which operates according to the scattered light, transmitted light or ionisation principle.

Certification of Smoke Alarms in the EU

EN 14604

According to the European Union’s Directive 89/106/EWG [german] as of 1 August 2008, only smoke alarms that are certified according to EN 14604 requirements may be introduced or produced and sold within the EU business circle. Fourteen institutions are qualified in Europe for the testing, monitoring and certification and for issuing a CE certificate for smoke alarms. 

A smoke alarm’s quality cannot be determined by the name of the testing institute. The tests are specifically defined by EN 14604 and are thus absolutely identical at all qualified institutions.

Does a smoke alarm have to carry a VdS Label?

No. A smoke alarm can obtain a CE certificate through the VdS Schadenverhütung GmbH, as well as from one of the other notified testing locations. These CE certificates are absolutely identical as they are based on testing procedures standardized throughout Europe according to EN 14604.
