Test F

Post by spccazares »

Has anybody seen this.

I have a NFS-640 V12 reading Test F on all Smokes, Duct Dets and Heats on the built in SLC loop 1. If I remove SLC it will go into trouble INVALD REPLY and after reconnecting all Detectors go back to normal. It'll stay normal for a day or two then all Detectors go back to Test F. SLC loop 2 all the detectors are normal and no issues.

Any ideas?
