When we bought our house 4 years ago the Gardtec 300 was installed. We have never had a problem with it but it keeps going off during the night and the alarm box outside keep bleeping when it rains heavy outside. My fiance tried to stop the alarm going off and now ALL the LED lights are flashing and wont stop even when I put in the code?? Does anybody please have an answer?? I have read the manual and it doesnt mention anything about this? Thanks
At the very least you need a new battery in the control panel.
I also suspect outside sounder - rain/damp is getting in, bet there are corroded joints &/or PCB along with a duff battery there as well.
