EAS2 Functional Description
11-4 68P80801E30-A 5/1/2002
The Site Controller and EAS2 interact in a master/slave relationship. The
Site Controller sends commands to the EAS2 to determine the status of
alarm inputs or set the state of control outputs. The EAS2, in turn, sends
alarm status responses to the Site Controller.
The EAS2 continuously scans the status of the alarm inputs, ensuring that all
alarms are consistently monitored.
