Access Manager 2000 User Manual 5 -23
Access Manager’s new Alternate Alarm Path (AAP) feature is available
for use with Access System 2000 products.
The alternate alarm path lets you establish separate alarm paths from one
node to two different Access Managers. Consequently, you can
■
simultaneously send each alarm to two Access Managers
■
designate an auxiliary Access Manager to receive alarms when
problems exist with the primary Access Manager
In addition, for each alarm path, you can specify the:
■
number of times the node controller will try to send an alarm to
Access Manager
■
time interval between notification attempts
■
length of time alarms are gathered before a notification attempt is
made

automatically downgrade to 1200 baud.
NOTE 2. Modem and ComDesign are not available for the second and third AS2000 nodes in a daisy chain, although
either of these access arrangements are available to the first AS2000 node.
