entering [PIN] + [Off].
Error Displays can only be read when the control is disarmed.
Some Control Panel Errors, such as battery trouble and any RF
troubles, will cause the keypad sounders to beep every 10 seconds.
The keypad sounders may be silenced for 4 hours by entering:
[PIN] + [Off].
The sounders will continue to resound until the problem is fixed.
To Clear a display, enter:
[PIN] + [System Reset].
Clear the Error Display only on the advice of your
installing company or if you are certain the problem
has been remedied.
NOTE: System faults may be read from any keypad because they
are system-wide. All other Error Displays are limited to
the partition the standard keypad is in. If you are on a
Master keypad, you may read Error Displays one partition
at a time.

7.7.3 Event History
The History Buffer stores the last 400 events in memory. The
DS7447/DS7447E can display all of these events. If this test is
performed from a Master keypad, it must be in Single Partition
Mode. The DS7445/DS7445i will only display those zones (1-8)
that have alarmed since the last Event History Readback. The
RF3341 cannot display history events.
To readback the Event History Buffer:
• Press [PIN] + [#] [8] [9]. On a DS7447/DS7447E keypad, the last
event to take place will be displayed. On a DS7445/DS7445i
keypad, the zone LEDs for any zones that have alarmed since
the last Event History Readback in that partition will flash.
• Scroll through the events using the [9], [6], and [#] keys as follows:
To begin scrolling back through the events, press the [#] key. The
[#] key will scroll you back through the history line by line. The [9]
key will scroll you back in reverse chronological order by event. A
[6] will scroll you back up through the events (toward the most
recent) by event.
Each event consists of two or three lines or display screens. The
first line/screen will be the event title and user. The second line/
screen will be the date of the event or the change being made. If
there is a third line/screen, it will be the date of the change.
NOTE: When performing this from a Master keypad, each partition
will display its own history.
• To exit the Event History Mode, press the [*] key or wait 20 seconds
and the keypad will exit automatically.
