Morse code in the Staff Room, help ?

[Kalinine]

After you upgraded all of your staffs and place the Fire staff in the fifth pedestal, Samantha will speak and the color panels above the Staff Room turn to white and red.

These panels blink and yes, this is a Morse code !

This code is a loop. It's begun with red light.

I translate the code and this is what I've found :

INFERNO

INFERNO

At the moment I didn't succeed to decode it !

If anyone knows how to decode it or have an idea to help me, thank you !

I can't decipher but I just posted a link to this thread on another deciphering thread so someone might come along to help

Maybe inferno is the cipher key.

Thank you ZzFLEX ZAPDOSzZ !!

Yes yourmapper, I've tried this key and I've got many words like "WARN", "LIBERATE" or "WE GREW WEAK".

I think INFERNO is a part of the cipher key !
