History Log
Local History Log Query
There is a limited set of query selection and
filter options available within the MXL-IQ.
More complex options are only possible
using an IBM PC that is running the
MXL-IQ history support program.
The user can get history log information
from the MKB-4 control panel by choosing
the TEST menu, selecting EVENT_LOG,
and pressing ENTER. A submenu of filter
selections is then displayed. The choices
are as follows:
Alrm_Only Only display or print
alarm events
Trbl_Only Only display or print
trouble events
Superv_Only Only display or print
supervisory events
Security_Only Only display or print
supervisory events
All_events Display or print all
recorded history events
Hist_Ctrl Use to turn History
on/off
Hist_Erase Use to Erase History
• If the user makes a selection from the
filter menu using the ENTER key of the
MKB-4, the output goes to the LCD
display.
• If the filter menu is selected using the
PRINT key of the MKB-4, then the output
goes to the system printer.
• If the group of events selected is empty,
then the MXL-IQ displays or prints, as
appropriate, NO HISTORY ITEMS
FOUND.
Query Selection
The MXL-IQ supports one query selection
option when generating listings or printouts
from the MXL-IQ control panel.
From the TEST menu, move the cursor to
the EVENT_LOG item and press the
ENTER key to select history information.
The MXL-IQ responds with a submenu that
allows an event type filter to be selected.
Cursor left or right until the desired filter
type (See Query Filters, below) is reached
and then press ENTER to display to the
LCD, or PRINT to print on the MXL-IQ
system printer.
The MXL-IQ asks for a starting date and
time. If a time is entered, it suppresses the
display or printing of older events. This
initial display of time and date indicates the
oldest history event recorded in memory. If
the operator presses the ENTER key
without making any numeric input, then all
events in the log are selected.
Query Filters
A limited set of event type filters is available
from the MXL-IQ control panel. The mutu-
ally exclusive filters are:
ALARMS
The Alrm_Only filter selection displays
or prints incoming alarms, alarm acknowl-
edgments, audible control, and resets.
This set of events gives the operator a
clear picture of the important events that
constitute an alarm condition.
TROUBLES
The Trbl_Only filter displays or prints
troubles and resets.
SUPERVISORIES
The Superv_Only filter displays or prints
supervisories and resets.
SECURITIES
The Security_Only filter displays or prints
securities, device arms, device disarms,
and resets.
ALL
The All_events filter displays or prints all
events.
HISTORY ON/OFF
The Hist_Ctrl filter turns the History events
on/off.
HISTORY ERASE
The Hist_Erase filter erases the History
events.
