ADT is reminding the industry, that as of December 31st 2013, it is now mandatory to conform to the requirements set out by the new standard EN54-23 from the European committee CEN.
The standard is designed to test the methods and performance criteria of visual alarm devices (VADS) and ensure that for the first time, a minimum lux output is achieved within a stated coverage area.
Now, a minimum light level of 0.4lux is stipulated on any surface, and manufacturers must specify the room size their product will cover with this level of illumination.
