The Wireless Alert DC monitors whether a door is open or closed using a two-part door contact sensor on a 350mm cable. The device body can be secured in position using an adhesive pad (supplied). Both parts of the door contact sensor can also be secured in place using adhesive pads (supplied), or screws (supplied).

The device can be set to trigger a notification email, sent to a user-selected address, if the monitored door opens, closes, or both.

The user can also configure delays (between 1 minute and 12 hours) before an alert is sent. In addition to this, the device can send a scheduled summary email detailing the number of alert events, percentage of open and closed time, and battery level.
