sixwheeledbeast Posted October 10, 2013 Posted October 10, 2013 It seems that only the PIR (zone 2) is going active. Maybe just "normal" environmental issues, there not a quad IIRC so can be more prone to FA's. If we get FA's on TMD's it's always the PIR zone. --Edit Also on a similar note I have had DT's FA's due to being next to a Dualcom aerial.
jiml Posted October 12, 2013 Posted October 12, 2013 Should have aske that first. Yes, it would seem the PIR is just seeing an environmental issue. What environment is it installed in?
datadiffusion Posted October 12, 2013 Posted October 12, 2013 As CG says harmonics come into play, i.e. multiples of the main frequency. And at WiFis relatively puny power not normally a problem; but different with other very low power applications such as alarms. But if its the PIR section FAing forget all that for now! Speaking in reverse, weren't the (much) earlier versions of the Risco iWise notorious for killing Wifi if wired with MW permanently enabled? So, I've decided to take my work back underground.... to stop it falling into the wrong hands

I remember a vision one doing that which was on 2.4gHz I think. Never seen it with 10gHz kit. Now we know the alarm is on zone 2, it is not related to the MW side.
