Alarm Monitoring. Toggles on/off the display of alarm messages in the Craft interface
screen. If ON, messages appear on the Craft interface terminal as alarms occur and

Relay Inhibit. Allows the user to enable, disable, or temporarily block the action of the
alarm relays. Values range from 0 to 256. Selecting zero enables immediate alarm

outage, or to block alarm relay operation on pending or non-critical facilities.

Clear Alarm Buffer. Removes all alarm messages from the display buffer referenced
