I have just found another picture on my phone of the intruder alarm system that we had to replace last week. I just wanted you all to see this is a picture of the internal wiring of the main box of the intruder alarm system. The green and yellow pvc electrical tape you see in the picture has been used to tape up the tamper circuits in the daisy chain method. Most alarms that I come across are wired in the fashion. Personally I use a silicon based connector that BT engineers use as I find them not only a more successful connection but are far more tidier than what you see here.
