This feature allows a Restricted Users to see and acknowledge only alarms associated with Tags assigned to specific Areas.  The “Area” is the “Security Area” assigned to the tag in tag properties.  The “Areas” are then assigned to the Restricted Users using the “Graphic Page Access” in User Security. The format in the “Restricted User Graphics Access” is:

almsummary:Area Number, Number2, Area n

For a continuous range of Security Areas, the format is:

almsummary:Area Number-Area Number n

For example, to assign the alarm summary for Areas 1 and two, the graphic page entry be: almsummary:1,2

Only tags assigned to Security Areas 1 and 2 will show in the alarm summary with the above example.

For example, to assign Areas 10 through 17, the graphic page entry would be: almsummary:10-17

Only tags assigned to Security Areas 1,2, and 10 through 17 will show in the alarm summary with the above two examples entered in the Restricted User Graphics Access.
