2.2.3. Installation of several adjacent safety light curtains 

 
When several safety devices must be installed in adjacent areas, it’s 
necessary to prevent the interferences between the emitter of one 
device and the receiver of another. 
 
Fig.10 gives an example of possible interferences between different 
devices and two pertinent solutions.
