expires, then the user will need to repeat the three badges in order to set or
unset the area. See also "Two badge unlock, one badge relock" on page 103.
Additionally, if a reader alarm control options specify three-badge alarm control
for users who are authorised to set and unset areas, this field defines the amount
of time permitted between the first and third badges. If the time expires, then the
user will need to repeat the three badges in order to set or unset the area.
Enter a number in seconds.
Random
The value defines the average percentage of the number of times that a valid
card or PIN is presented to open the door that the door's "Door random bit" event
will be activated.
The "Door random bit" event may then be used in the controller's macro logic
programming to activate an output or another event. For example, if the
percentage value was set to 20, the "Door random bit" event would be activated
an average of once every five times a card or PIN is successfully used at the
reader.
Alternatively, if the Random lockout time (below) has a value, then the "Door
random bit" event locks out the door for the specified time. During this time, the
door cannot be opened by any user.
Enter a number in the range 0 to 100.
Random lockout time
When the "Door random bit" event triggers (as described in "Random" above),
the door can be locked out for the amount of time specified in this field. During
this time, the door can only be opened by a user with the "Privileged" flag. Any
LCD RAS attached to the door will display "Locked Out".
Enter the time in seconds.
Unlocked Schedule
The option controls the time when the door can be opened without the need to
use a valid card or PIN. Free access is allowed when the schedule is valid.
Click Browse "..." to open the Schedule list. Uncheck Disabled check box and
then select an appropriate schedule.
Low Security Schedule
The option controls the time when the door can be opened with either a card or a
PIN if the door is configured to require card and PIN. Only a valid card or PIN
code is needed to open the door when the schedule is valid.
Click Browse "..." to open the Schedule list. Uncheck Disabled check box and
then select an appropriate schedule.
