Abstract
A medical products storage device, such as a refrigerator, includes a door having a viewing window. The window has a variable opacity so that the viewing window may be transparent or opaque, depending on conditions of the medical products storage device. Light emitting diodes embedded in the viewing window are used to indicate an alarm condition.
