date of each event, along with the zone number, access code
number or any other information pertaining to the event.
If the Event Buffer Follows Swinger Shutdown option is
enabled, the event buffer will not store events after the
Swinger Shutdown level has been reached. This will prevent
the panel from overwriting the entire buffer if a problem exists.
The event buffer can be viewed in three different ways: from
an LCD keypad (see "[*][6] User Functions" on page 10)
printed on-site using the PC5400 printer module, or it can be
uploaded using DLS software.

5.21 Keypad Lockout Options

The panel can be programmed to "lock out" keypads if a
series of incorrect access codes are entered. Once the Num-
ber of Invalid Codes Before Lockout limit has been reached,
the panel will lock out all keypads for the Lockout Duration
and log the event to the event buffer. For the duration of the
lockout, the panel will sound an error tone when any key is
pressed.
NOTE: The Invalid Code Counter will be reset every hour.
To disable the keypad lockout option, program the Number of
Invalid Codes Before Lockout as [000].
NOTE: If Keypad Lockout is active, the panel CANNOT be
armed / disarmed with a keyswitch.

5.22 Keypad Blanking

If the Blank Keypad When Not in Use option is enabled, the
panel will turn off all lights and LCDs on the keypads when no
keys are pressed for 30 seconds. The keys, however, will
remain backlit.
The panel will turn the lights and LCDs back on if entry delay
begins or an audible alarm occurs. The lights and LCDs will
also come on if a key is pressed or, if a valid access code is
entered when the Code Required to Restore Blanking
option is enabled.
NOTE:If using a PC5132 v3.0 or greater, and wireless keys, do
not enable the Code Required to Restore Blanking option, as
the keys will not function correctly.
If the Power Save Mode option is enabled the panel will blank
all keypad lights including backlighting when AC power fails,
in order to conserve the back up battery.

viewing in dim lighting conditions. If the Keypad Backlighting
option is enabled the keys will be illuminated.

5.24 Loop Response

The normal loop response time for all zones is 500 millisec-
onds. The panel will not consider a zone violated unless it is
violated for at least 500 milliseconds.
Zones 1-6 on the control board, however, can be programmed
for a fast loop response (under 40ms).
Zones 1-6 are Fast Loop Response . . . . Section [030]: [1-6]

5.25 Keypad Tampers

If the Keypad Tampers Enable option is selected, the panel
will display and transmit a General System Tamper reporting
code if any keypad is removed from the wall. When the key-
pad tamper is restored, the panel will transmit the General
System Tamper Restoral reporting code. All keypads should
be properly installed and secured before enabling this option.
NOTE:The auto arm cancellation code is not transmitted when
a reset is required because a user has not cancelled the auto-
arming sequence.

tamper and restore all keypads to ensure proper functioning.

5.26 LINKS1000 Cellular Communicator*

The LINKS1000 Cellular Communicator can be used three dif-
ferent ways:
• as the sole communicator for the panel
• as a backup for either or both telephone numbers
• as a redundant backup to the land line communicator,
A LINKS Preamble is programmable for each telephone num-
ber in the event that the land line number is local but the
LINKS is required to dial an exchange. When programming a
LINKS Preamble, all unused digits must be programmed with
a hexadecimal "F".
NOTE: If a LINKS1000 is connected to the system, make sure
the Maximum Number of Dialing Attempts is programmed to
be 008 or greater (section [160].
Using LINKS1000 as the Sole Communicator
The panel can be programmed to report an event only using
the LINKS1000 cellular communicator. To program this option,
select only the LINKS1000 in the Communicator Call Direction
Options. The Call LINKS as well as Land Line option must also
be enabled.
When the selected event occurs the panel will only attempt to
call central station using the LINKS.
Using the LINKS1000 as a Backup Communicator
The panel can be programmed to call using the LINKS1000
Cellular Communicator if the panel is having difficulty commu-
nicating an event using the land line. To program this option,
select both the telephone number and LINKS options in the
Communicator Call Direction Options. The LINKS is Backup
of Land Lines option must be selected.
When used as a backup communicator, the panel will attempt
to call the central station in the following manner:
the panel will try to call using land lines – if unsuccessful, the
panel will try to call using the LINKS
