Logic Alarm Elements
The DGC-2020 activates a Logic Alarm when the LOGICALM input is TRUE. A Logic Pre-Alarm is
activated when the LOGICPALM input is TRUE.
Configurable Elements
Configurable elements (CONFELMNT1-8) are connected to the logic scheme as outputs. These elements
are configurable in BESTCOMSPlus under Programmable Outputs, Configurable Elements. The user can
assign a string of up to 16 characters, configure whether the element should generate an alarm or pre-
alarm. If used for alarm or pre-alarm, the user's text is what will appear in the alarm or pre-alarm
annunciation and in the DGC-2020 event log. In addition, the configurable element status can be used to
generate modem dial outs which display the user's text on modem equipped DGC-2020's.
Other
MODEM is used to connect the Dialout input to an output of another logic block.
