We have a 4100 Simplex fire system that has a reappearing ground fault. What is the correct trouble shooting procedure to isolate this problem?
I need a starting point and procedure to trouble shoot this 4100 system that has an intermitent ground fault. Usually when it rains. All the outside sensors have been opened and no water was found.
