I have an Accenta G3 alarm in my house and lately I'm getting a lot of false alarms . It says that it is being triggered by the back door sensor and the rear window shock sensors (2 LED's - one lit, the other flashing). I've tested the sensors, and they do work as expected. I can't see where the wiring goes as it's been hidden, so I can't see there being any wiring damage. Do you think it may be the battery that has come to the end of it's life. We've lived in the house for 5 years, and we've never had it serviced(I know, but I don't trust guys comming in and fiddling with the system and having a good look at the audi outside and the nice gadgets inside).
