To manage your installation
locally!
The keypad and display are used to set the Sepam parameters and protection
functions and to display measurements and alarms.
The advanced UMI does not give access to the matrix (use SFT2841).

To make the most of your
Sepam !
The SFT2841 tool may be used to set parameters and protection functions and
«customize» Sepam. It provides the alarm history, disturbance records and
parameter down and uploading.
