Caution - Space Station alarm system by DLR

The Space Station alarm system has three levels – or even four, if you include the harmless "Advisories".
The lowest level is the yellow "Cautions" – they also have their own sound [caution.wav] and flashing lights on the Space Station, unless we have not “inhibited” or “suppressed” them. When a caution is “inhibited” it does not get processed by the central computer of the Space Station. When Cautions are “suppressed” an alarm is triggered on the laptop or our display, but "Lights and Tones" that would wake astronauts at night are not turned on. Of course, very specific guidelines exist to decide when an alarm event can be turned off or suppressed.
