Alright so someone reported in the comments that if you press the buttons in a certain order it says in red text "Something has happened..." and starts playing an alarm sound and creepy ambiance. THEN in the room that sort of looks like a b from top view there will be a transparent gray stalker NPC typing on a radio that when approached disappears popping up text saying something along the lines of "what was it(?) doing with it(?)" (I can't give an exact transcript because I can't get it to trigger the something has happened text again)
