I am working on a job where the fire alarm system keeps showing a ground-fault in one of the adressable loops. The only problem is, it doesen't show it long enough to trouble-shoot it.
Every time that I try to isolate any part of the system the trouble goes away and doesen't come back for hours. The ground -fault is very intermittant.
Any ideas as to how I could pin-point an intermittant ground-fault?
