Good morning all. I have removed my alarm box from our house due to not using it for years now. I have installed it in my shed due to garden hoppers robbing sheds etc just lately. my problem is all the cables were under the floor boards etc so I do not have a clue where to connect the one sensor I have put in the shed. I decided not to put the bell box in due to the alarm panel being loud enough on it’s own. Can anyone send me a pic of where to connect just the one sensor. Thanks in advance. Smed
