For these purposes the magnetic door sensor, the turnstile rotor position sensor and
the position sensor of boom barrier are connected to the input of panel. The input
used to connect the sensors, is called the input of the door contact.
Antipassback
Antipassback function is implemented in access control panels to prevent the
situation when user gives his RF ID to another person after passing into the
premises. If this function is on, control panel tracks an RF ID position
– inside or
outside the premises. On any attempt to pass in the same direction twice the panel
denies access and stores “Access Denied, Antipassback” event into the Log.
Antipassback function can be set on only in case of the double-sided door control.
Global antipassback
Prevents user door pass from the areas where he must not appear. The facility
spitted into the closed areas connected with double-sided access points, in which
system supervises the personnel appearance for this purpose. System detects the
global antipassback violation when somebody tries to re-enter such area without exit
or tries to enter somewhere from the area he have not enter. System generates
message “GLOBAL ANTIPASSBACK: Access Denied” in case of global
antipassback violation.
Door time
If door sensor is open, corresponding access point goes into alarm. Alarm is not
invoked, if contact is opened during Door Time interval. This interval starts when
access is granted and lasts for the programmed time or terminates on opening and
subsequent closing of door contact.
Code matching attempt
Control panels can activate alarm on attempt of a code (or RF ID) matching. Code
matching is considered when invalid code (or RF ID) is entered several times
successively. Valid code entering clears the counter. This function switching On and
number of code entrances are subjects of programming.
Schedules
Date and time of valid access are indicated when setting user access rights. Control
panel stores up to 250 time zones.
250 week schedules can be combined from these time zones.
Moreover, control panel can store up to 250 holidays, which happen once a year.
Time zones
Time zones are a part of schedule. This is a way to organize a range of days and
times and associate it with access levels.
Time zones are utilized by the application to validate, authorize, or perform various
functions based on schedules.
