So after toning a few wires, the only zone I cannot identify is zone 17 - a wireless device notionally since I have confirmed that Zone 18 is the wireless motion detector paired to the RF5108. The unterminated wire near my sump is connected to Zone 16 though I do not know how this is programmed in the panel. WRT Zone 14, the pair of wires connected to Z6 and COM of the PC5108 were shorted together on the disconnected motion end so I suppose this is why it did not show a fault.
Any ideas as to how to identify the device connected to Zone 17 (or if there is one)?
