The DA-9ADP was designed primarily as a Freezer or Fridge door alarm. It can be easily installed on any door without any tools. This model has an adjustable delay circuit which allows you to keep the door open for a period of time silently. After this delay time, it emits a pulsing tone to alert you to the fact that the door has been left open.

The delay comes preset to 45 seconds but you can adjust it between 2 and 120 seconds. Longer delays are available as a custom order. The DA-9ADP will likely operate for about a year under normal use on a single 9 volt alkaline battery (included).
