Viewing and Printing a Read Status
4.4.4 How to View and Print Hidden Event and Alarm History
The control panel maintains a copy of the History buffer. For instance, if someone clears the His-
tory buffer using Status Change programming option 4, the control panel retains a copy of the His-
tory buffer. The copy of the preceding History buffer is called a Hidden History buffer and a copy
of the preceding Alarm History is called a Hidden Alarm History buffer.
If you attempt to view or print history and the control panel displays one of the screens shown
below you can use the options listed in the table below to view the contents of a Hidden History
buffer.
Options for viewing and printing Hidden History and Hidden Alarm History do not appear in the
LCD display when in Read Status. You can view and print the contents of these Hidden History
buffers using the options listed in the table below. You read and print Hidden History and Hidden
Alarm History the same way you read and print history using the options that appear on the "Read
Status" screen. The table also contains references to the sections that contain instructions for read-
ing and printing history.
