LK, I'm a little confused here. I don't mess with alarms much but I know that, on the couple of monitored systems I've touched, I can go in and cut the phone lines to the monitoring company and not affect the integrety of the local system one whit. All pulls, smokes, and local alarm will still function 100%. Why would they cry about a system that is inherently better in the first place (assuming it was installed and inspected originally)?
