3.7 Emergency blocking
In emergency, press keys + to secure the door and to prevent any opening procedure for 30 mins
(settable from 1 to 99 mins).
It is not possible to change the emergency blocking keys.
3.8 CIT anti-passback procedure
This procedure can be used to limit the period of time within which a code may be used and the number of
consecutive openings.
If the anti-passback function is activated in “CIT” mode:
■ The first time the code is entered, the door is opened, and the time delay defined in the Configuration
Tool is started.
■ The same code may then be used several times up to the maximum number defined in the Configuration
Tool.
■ Once the code has been entered the maximum number of times or once the time delay has ended, the
code may no longer be used.
The code can be reactivated by a user from another rights group logging on.
As soon as the CIT anti-passback time delay has started, all other opening requests and attempts to access
the menu are prohibited until it has ended.
If a code is entered during this period, the message "Anti-passback active" is displayed.
Once the code has been entered the maximum number of times or once the time delay has ended, the
icon is displayed to indicate that the anti-passback code may no longer be used, but that all other codes may
once again be used.
The icon disappears once a user from another rights group has logged on.
Until the CIT anti-passback code has been rearmed (by a user code), the message "Invalid code" is
displayed if the code is entered.
3.9 Wrong code blocking rules
There are 2 rules that define the blocking time after entering several wrong codes:
■ Increasing blocking time:
• After 4 wrong codes = 10' blocking
• Then, if the next code is wrong = 20' blocking
• Then, for each wrong code entered = 30' blocking.
■ Fixed blocking time; Blocking time value is 3 to 99 minutes for class B or C and 8 to 99 minutes for class D.
Entering the correct code will reset the wrong code counter.
