So called "hands-on pro's" always attempt to justify the reliability of wireless alarm systems without manufacturer specifications and support. Its so simple to have the manufacturer specify / warrant theyre product reliability against Radio Frequency Interferences (RFI).. Who knows better than the product designer, -tester, -producer? Why do manufacturers not specify that attempt of "hands-on pro's" who explain a imaginative RFI detection system?
Does the salesman; Does the installer; or Does the monitoring agent know better? They seems to be the only who know that the night owl cry (RFI detection) don't exist; NO ALARM during RFI, but they don't tell that to everybody!
Who attempt purchaser "nose leading", some call that "Leg twisting"?
At least it seems that I succeed with the "so called" alarm pro's and they're imaginative unsuccessful and unjustified statements subject wireless alarm systems reliability during RFI.
By the way, do somebody have a small tool called "nose players", it will allow to twist "so called" pro's verbal juice even more.
I don't think that you have "nose players" oversees but its not required, it seems that you have "jumping beans" instead... A lot of "jumping beans" are present in this NG at least.
