Using the RS-485 Node Port

The RS-485 Node port allows you to activate external alarms that alert on-site personnel to

critical situations. Using the ACO function will keep the alarm active until it is manually

cleared form a control terminal.

Connect the NODE jack of the INF+M card to the external alarm equipment. This is another

RJ-48 jack; it provides a set of form-C relay contacts to the external alarm equipment. Figure

C-10 shows the pin locations on this jack, which are the same as the COM2 jack. Table C-8

lists the associated signal pinouts.

The alarm interace is activated by the ACO setting. This will activate the device when a

designated alarm occurs. See chapter on Alarms to review the conditions and settings

necessary to enable this feature.

Connect pins 4 and 5 to provide an open relay contact to the external device upon occurrence

of an alarm. Or, connect pins 3 and 5 for a relay contact closure upon alarm.
