Modify Allowed Station List Dialog Box
mutually exclusive option at a time by clicking on the applicable button, as
follows:
This security option disables ring security, allowing all stations on the ring.
This security option enables ring security with the condition that any station
entering the ring will generate an alarm unless it is on the secure list. The
device will place the station address on the Allowed Stations list.
This security option enables ring security with the condition that any station
not on the secure list and that enters or currently resides on the ring will
generate an alarm and be removed from the ring.
The middle portion of the dialog box contains two scroll lists (Allowed
Stations and Disallowed Stations), together with associated buttons that
let you move station addresses back and forth between these two scroll lists,
as well as to add or delete stations from the ring. The left-hand Allowed
Stations list displays the list of stations currently allowed on the ring.
Double-clicking on any item in that list will move it to the right-hand
Disallowed Stations scroll list, except that you cannot move a station from
the Allowed Stations list if the security for that station address is set to
Enable with Alarm. Alternatively, you can highlight any station address in the
Allowed Stations list and then click on the > button to move it to the
Disallowed Stations list (again, you cannot move the station address if its
address is set for the Enable with Alarm state, and the > button remains
grayed out (inactive). If you move an address to the Disallowed Stations
list, the > label becomes active, with that condition remaining in effect until
you click on the Apply button to implement the change(s).
The right-hand Disallowed Stations scroll list acts as a scratch pad or buffer
to store addresses currently disallowed on the ring, but which you may want
to move to the Allowed Stations list in the future. The ring does not read
this buffer to deny ring access to certain stations; instead, the ring denies
access to all stations not explicitly included in the Allowed Stations scroll
list. Double-clicking on an item in the Disallowed Stations list will move it
to the Allowed Stations list. The normally inactive (grayed out) < button
becomes active when you make any such change, with this condition
remaining in effect until you click on the Apply button to implement the
change(s).
Unless the security for a given station in the Allowed Stations list has been
set for Enable with Alarm state, highlighting that station address and then
clicking on the > button will move the selected station from the Allowed
Stations list to the Disallowed Stations list. The > symbol then remains
Disable
Enable with Alarm
Enable with Remove and Alarm
