The DA20 is a unique product. There are some devices which signal if a freezer is defrosting (based on temperature rise), and some devices produce an audible alarm while a door is open, however the DA20 is completely different. It’s innovation is found in it’s ability to remain silent while the door is open, for a user adjustable period of time, before generating an alarm.
