Ancillary functions
Since the signals for remote tripping can be set to alarm only, any other desired signals can be transmitted as
well. After the binary input(s) have been activated, the signals which are set to cause an alarm at the receiving
end are transmitted. These alarms can in turn execute any desired actions at the receiving end. Another 24
transmission channels are available for the transmission of remote alarms and remote commands, and 4 ad-
ditional fast transmission channels can be ordered optionally (see also Section 2.13).
