We have a disused Micron alarm system in our house, which is about 15 years old. It hasn't been used for about 7-8 years, and it is designed to phone a preset number and play back a recording, informing the called person that the alarm has been triggered. It has a humming sound coming from the AC inputs, but all the sensors and keypads are dead. I think the phone line goes through it, and I was wondering if it could be degrading or impacting our DSL connection at all. We only have ADSL1, and get around 4Mbps down and 0.90Mbps Up. This is around 2Km from the exchange/cabinet (Not sure which).
Here is an Imgur album of the old system with horrendous cable management. https://imgur.com/a/coAmd#0
If anyone has dealt with these systems in the past or knew how these sort of alarms can impact ADSL, I'd be very pleased to get some help.
Thanks
