Hi Rocky,
You (sorta) beat me to it. But great minds think alike!=20
I don't and haven't used (Ademco) Honeywell products or wireless products s=
ince the 5600 wireless days. But Napco has an earth ground terminal on thei=
r receiver. So, to the OP Airdorn, I'd suggest try using an earth ground an=
d or a shielded cable on the wire between the panel and the receiver. (and =
possibly any other exposed wire ( have to experiment))=20
With regard to this happening randomly, if there IS a strong RF source in y=
our area such as a major airport or government base, etc. remember that eac=
h length of wire is (in effect) an antenna of sorts and makes grounding  an=
d shielded cabling all the more important. And if those possible sources of=
 RF ARE in your area, how do they relate geographically to where your alarm=
 systems were installed? You can try 1000PF capacitors to ground at various=
 points also.

Had a similar problem years ago with wired  (not wireless) PIR detectors at=
 miscellaneous locations. Motion detector of a couple of manufacturers woul=
d just sit there with no movement and go into multiple activations over a p=
eriod of time. I had to sit there for hours watching the detector before I =
witnessed what was happening. Shielded cable and tinfoil inside the case of=
 the PIR cured it but we never did find what the source was. We suspected t=
hat it might have been a Taxi cab company's two way radios but we just didn=
't have the resources to prove it.
