[QUOTE="Tanis143, post: 3527775, member: 43724"] There is a reason why data has to follow a strict no touching code, cross contamination of EMI can corrupt data packets. Alarm wiring is a simple resistor circuit. If it has continuity, all is good. If the continuity is broken then the alarm goes off. Coax is a bit more lenient than CAT5e/6/7/x due to the fact it has proper shielding to prevent egress/ingress, but even it is susceptible. I had a house that had seen 4 techs come out for intermittent tiling. Swapped boxes, replaced fittings/splitters. The last tech out put in an amp and overdrove the signal. I did an ingress check and saw some ingress spikes. The line going to the living room was zip tied onto a conduit that was going to an outside outlet. When I took the line off the conduit and mounted it 3 inches away the ingress spikes stopped. So its not just that the alarm people are lazy, they just do not need to isolate their lines to prevent data corruption. [/QUOTE]
