hi guys
to start off i had a ADT burglar alarm installed in my house years ago it is now disconnected at there end. a very good friend said to me that although its disconnected at there end it could still be causing issues with my connection since it is still powered up at my house it also still beeps and goes off occasionally. he suggested i call a sparky to get him to remove it from the mains so it can no longer send any signals my question to you is would this work or would it still cause issues if any and if it could be causing issues how bad could it actually be??
im with orcon on unlimited vdsl with phone line
i have attached a picture with my current line stats

thanks for any insight into this
