Huh, well I've been through the logs and there's nothing I can see that explains the blip.

I'm half tempted to the ladder out and just disconnect the sirens and everything and replace it...

I may be drowning without hope of rescue here

I looked through the system and noticed there are 3 keypads listed in the diagnostics, although I onyl have 2 keypads (one upstairs, one downstairs).

The third keypad is listed as number 15 and has 0% connectivity, would anyone know why you'd have a 3rd keypad in the diagnostics that isn't listed anywhere else?

I'm also wondering if it was caused by some sort of battery problem as there are a few "CU+/-" battery errors listed in the log (they could also be from when I was trying to sort it out too so that isn't conclusive.

The battery is brand new, fitted only a couple fo months ago... but you never know.

I suspect it might be a PCB problem, mostly because a power reset resolved it for now, I'm a computer network techie originally and it definitely feels like an electronics problem.

Nothing in the programming manual provides any guidance for this sort of problem.

the manual will help you program it, not fix it when its broke im afraid.

RKP 15 is an engineer keypad and if at 0% isnt fitted, so dont worry about it.
