Konnected blew the fuse

Hi, after I plugged Konnected Alarm Panel into the outlet for the first time it blew my fuse and there was a smell of burned plastic. I bought a new power adapter with the same specifications as the one that came with my order (12V/2A, AC100-240V~50/60Hz) and this time the green led flashed for a second but then the light faded and there was no wifi network available. I tried the new adaptor with the three add-on Konnected panels that I have and always to the same result - green light for a sec and then nothing.

I live in Czechia and have the standard Type F electrical socket

So are all my Konnected devices bricked now?
