no PIN can then be used to release the
door.)
The CC-8521BN includes an invalid PIN
penalty feature that protects against an
unauthorized user gaining access by
entering successive guesses of the PIN.
When an invalid PIN is entered, the system
then ignores all further PIN entries for 5 to
60 seconds. The default value is 5
seconds. To change the Penalty Time
enter *56*N*, where N is from 5 to 60
(seconds).
After five successive invalid PIN entries the
penalty time is automatically set to 60
seconds and remains at that value until the
valid PIN is entered. This feature greatly
increases the average time it would take to
successfully guess the valid PIN and is
particularly effective in protecting shorter
PINs.
An Invalid PIN can be made to sound an
alarm (three short beeps) whenever an
invalid PIN is entered. This feature is
disabled by default. To enable enter
*13*1*. To disable enter *13*0*.
6.2.3 Door Monitoring
The system includes a number of functions
that make it possible to monitor the status
of the door during operation. With the
exception of the Open Duration function,
these features require that a door position
sensor be installed on the door and
connected to the Control Panel as
illustrated in Figure 5-1.
Open Duration
The Open Duration is the time period
during which the door is released
(unlocked) after either a valid PIN is
entered or a release button is pressed.
The default Open Duration time is 5
seconds. To change the Open Duration
time enter *20*N*, where N is from 5 to 60
(seconds).
Anti-Tailgating
The Anti-Tailgating mode is provided to
prevent the door from being re-opened a
second time during the Open Duration time
period. This function is disabled by default.
To enable Anti-Tailgating enter *23*1*. To
disable Anti-Tailgating enter *23*0*. When
this function is enabled the door re-locks
immediately after it closes independent of
the Open Duration setting.
Door Propped Alarm
The Door Propped Alarm function sounds
an alarm when the door remains open for
more than 1 to 255 seconds (Door
Propped Alarm Delay Time) or until the
door is closed. This function is disabled by
default. To enable the Door Propped
Alarm set the Door Propped Alarm Delay
Time by entering *22*N* where N=1 to 255
seconds. To disable the Door Propped
Alarm enter *22*0*.
The Door Propped Alarm Duration can be
set to sound either continuously until the
door closes, or until a time out period
expires or the door closes, whichever
occurs first. Enter programming code
*23*0* to set the Door Propped Alarm to
sound until the door closes. To have the
Door Propped Alarm sound until a time out
period expires or the door closes
whichever occurs first, enter *23*N* where
N=15 to 255 seconds (Door Propped
Alarm Duration).
Forced Door Alarm
The Forced Door Alarm function sounds an
alarm if the door is opened without being
released by the system. This function is
disabled by default. To enable the Forced
Door Alarm enter *24*1*. To disable
Forced Door Alarm enter *24*0*. The
Forced Door Alarm is silenced by entering
the valid PIN on the keypad or by disabling
the Forced Door Alarm function by entering
programming code *24*0*.
