External Battery Back Up
The XLink™ Bluetooth® Cellular Phone Interface works with your Sensaphone® allowing the Sensaphone® to dial and receive calls via a cell phone rather than a land-line. However during a power failure, the XLink™ does not have the ability to communicate.
The solution to the problem is this External Battery Backup. It has a 400va capacity and overload protection. During a power failure, it will provide approximately 20 minutes of backup time. For use only on with the XLink™ Interface.
