Im only running with 2 detectors on a small run of cable, i will swap the detectors over with some spares I have
From what I can gather the Gent nano panel is very cut down from the stuff you guys probably deal with and as such quite straight forward menus, but i will look again and see if I can see anything thats responsible for this clicking
I might also try the loop with no detectors at all in the bases and see if it still clicks
