Dear gentlemen, where in EN 50131-1 or PD6662 I can find the restrictions about allowance of wireless system for grade 3?

[@NorbainTV]

Hi Anton, Grade 3 is currently only given to wired security solutions, so any wireless systems will fall into Grade 1 or 2

[@steliossideris6498]

because someone has to pay to see εν 501310?
