I was disappointed with a recent installation mainly on the sensitivity of the dual stage sensor. This sensor is built into the brain. Anyway, I am considering the subject alarm and would wish to get some input on it in regards to the shock sensor (which is a plug in type). Also I noticed from reading on the specs, this unit communicates on the AM band. It seems that the FM band is a common thing nowadays...but i don't mind as long one cannot intercept the transmission and use it to disarm the alarm. Not a show stopper, but can anyone confirm if its a blue LED..again if its red..then that is okay. cj

Addendum..any other feedback on the alarm features, user friendly, etc. will be greatly appreciated..cj
