Access point
Access point is a logical concept of the access control system implying the control
of passing through the door in one direction. It consists of reader, access control
panel (or it’s part), door supervision devices (like magnetic contact, RTE etc.) and
door locking device. For instance, the turnstile with two way passes has two
Access points – one for entrance and the other one for exit, door of this type is
called double-sided door. A door with the reader on one side has only one Access
point – Entry point, and it is called single-sided door.
Antipassback
The Antipassback function is implemented in the NDC-F18 access control panel in
order to prevent the situation when user gives his ID to another person after
passing to the premises. If this function is on, NDC-F18 tracks an ID position – Inside
or Outside the premises. On any attempt to pass in the same direction twice NDC-
F18 denies access and stores “Access Denied, Antipassback” event into the Log.
The antipassback function can be set on, only in case of the double-sided door
control.
Code matching
NDC-F18 can arise alarm in case of an attempt of a code (or ID) matching. The
Code matching is considered when invalid code (or ID) entered several times. Valid
code entrance clears the counter. This function switching on and number of code
entrances are subjects of programming.
Door Contact (DC)
In access control systems various sensors are used to supervise the status
(opened or closed) of the pass way – magnetic door sensor, sensor of the
turnstile rotor position, inductive sensor of car passing through the road barrier,
etc.
The Door Contact terminal of NDC-F18 is intended for connection of these sensors.
Door time
If the door contact is open, the corresponding access point goes into alarm.
Alarm is not invoked, if the contact is opened during the Door Time interval of
time. This interval starts when access is granted and lasts for the programmed
time or terminates on opening and subsequent closing of the door contact.
Downloading
NDC-F18 is to be downloaded after setting all parameters – modes of inputs,
outputs, access rights and others on the computer. During the downloading
parameters are rewritten into the access control panel. If you change control panel
parameters in your computer, they will not take effect until this parameters down-
loaded into the control panel.
PIN (Personal Identification Number)
Some readers have built-in keypad. The keypad may be used to enter ID in this
