This document describes options for implementing antipassback in the U-PROX system.

Функціонал антидублів (Anti-passback) у системі U-PROX працює лише для двосторонніх дверей.
If one-way doors are present in the system, they must be defined as “Internal” and should not allow passage between zones where anti-passback is active.

U-PROX IP400 Controller:

Supports local anti-passback on two-way doors
Supports global anti-passback when used in conjunction with the U-PROX IC A controller

Equipment connected via the NDC-B052 controller (legacy-device support mode in U-PROX):

Supports local anti-passback
Supports group anti-passback if:
- Legacy controllers are set to “Slave” mode
- They all belong to the same group of slave devices under NDC-B052

Section I describes the general method for connecting equipment via NDC-B052.

Section II covers the use of the U-PROX IC A controller to provide global anti-passback control.

ATTENTION!

Starting with U-PROX software version 3.57.1, a network settings configurator appears in each device’s properties, allowing you to change network parameters (provided the controller is online).

However:
Changes to the IP address for the AntiPassBack controller will not be applied via this configurator.

It is recommended to perform all IP-address configuration for the U-PROX IC A controller (used for U-PROX IP400) over USB, using the UProxIPConfigurator.exe utility.

I. General option for connecting equipment via NDC-B052

Local anti-passback is configured the same way as in the U-PROX system.

Group anti-passback is implemented by creating groups on the NDC-B052 controller and adding two or more legacy controllers with two-way doors configured. In each controller’s settings, you must enable the “Global Anti-Passback”option.

When doing so, the wiring order for readers must be clearly defined:
Side A (or Side B) of each reader must be assigned to a single direction—either Entry or Exit, according to the flow logic.

ІІ. option with U-PROX system controllers – U-PROX IC A and U-PROX IP400

To configure the coordinated operation of a U-PROX IC A controller with the corresponding U-PROX IP400 controllers (network interaction and integration in U-PROX software), perform the following steps:

Network-Level Configuration

Refer to the document “Initial IP Controller Setup Using UProxIPConfigurator”, which provides connection diagrams and configuration examples. Pay special attention to:

Pages 36–41 — network connection diagrams.
Pages 37–38 — detailed description of port settings used for interaction between controllers.

Configuration in U-PROX Software

After completing the network setup, continue configuration within the U-PROX software.
See the section in the documentation “U-PROX IP User Guide”, pages 89–92. Note the following fragments:

Sequence for adding the U-PROX IC A controller to the system
Definition of interaction modes with IP400
Configuration of global anti-passback control
Verification of correct event routing and synchronization between devices

You need to assign access controllers to the anti-duplication controller in the U-PROX software:

In the door settings of the U-PROX IP400 controller, the use of the “General” anti-duplication feature must be enabled:

You can do this via the global menu “Relative position of doors and rooms” or directly in the “rooms” themselves by configuring the anti-duplication zoning and the placement and direction of door entrances/exits:

After completing the settings, you need to upload the configuration to all controllers:

controllers must be connected – NO red mark! (which indicates loss of connection with the equipment)

After configuring anti-passback operation, it is recommended to execute the “Start” command, available in the menu when you log into U-PROX with administrative privileges (by default, or as a user with the “Administrator” option):

“Initialize” – resets each person’s anti-passback location to the “Undefined” state;
“Stop” – disables anti-passback;
“Start” – re-enables anti-passback after a “Stop” command.

FEATURES:

Upon loss of connection to the U-PROX IC A controller, the U-PROX IP400 will switch to local anti-passback mode.

Local anti-passback operates per controller and per card individually, after the connection to U-PROX IC A is lost.
Global anti-passback operates system-wide per person (regardless of how many cards a person holds).
After loss of connection to U-PROX IC A, when a card is used for an allowed passage, there is a 3 s delay before activation while the controller attempts to re-establish communication with U-PROX IC A.

You can disable anti-passback for individual personnel identifiers by setting the card parameter “Anti-passback Disabled”.

The “VIP” option automatically includes the “Anti-passback Disabled” attribute.

Assign “Anti-passback Disabled” to the necessary cards and download the configuration to the controllers.

For particularly critical personnel who must always be able to pass, you can also assign the “VIP” option to their cards.

GROUP CHANGES TO SETTINGS:

Quickly and for everyone – this can be done through “quick change of personnel parameters” and uploading the configuration to the controllers.

Sequence of actions when global anti-duplication (fire unlock) fails to start

Check the following possible issues:

The connection between the IP400 and IC A controllers is not configured.
“Anti-passback” is not enabled in the IP400 door parameters or in the IC A control menu.
Rooms, their doors, and their spatial relationships are not properly configured.
The configuration has not been uploaded to the controllers.

General information about the operation and configuration of global anti-duplication:

Про контрRole of Global Anti-Passback (“AntiPassBack”) – “U-PROX IC A”

Page with description – https://access.u-prox.systems/uk/product/u-prox-ic-a-2/
Found on the “U-PROX” system website – https://access.u-prox.systems/uk/

You can configure the system either with perimeter anti-passback or with full zonal anti-passback.

Description of settings is provided in the relevant documentation:

Local anti-passback – operates per personnel card independently, within a single controller.

Global anti-passback – using the U-PROX IC A controller – operates per person, regardless of how many cards a person holds.

With correct configuration of U-PROX IC A and U-PROX IP400 controllers, immediately after loading the configuration and upon the first granted passage, the following must be true:

In the U-PROX IP400, anti-passback must be enabled on its doors
The U-PROX IC A controller must be assigned in the U-PROX IP400 parameters
Both controllers (U-PROX IP400 and U-PROX IC A) must have the configuration loaded

The correct sequence of events is as follows:

If you see a sequence similar to the one below:

and the U-PROX IC A controller is present and in use, but there is no connection with it in the U-PROX IP400, which means that something is not fully configured.

The following information may also be useful:

3-second delay when granting passage, with the specified and configured parameters of the anti-duplication controller, is a message about the LOSS of connection between U-PROX IP400 equipment and the global anti-passback controller U-PROX IC A.

This usually indicates that:

There is NO connection to the U-PROX IC A anti-passback controller
The IP address of U-PROX IC A is NOT configured in the network parameters of the U-PROX IP400 controllers
The read port of the U-PROX IC A controller must match the write port of the anti-passback server in all U-PROX IP400 units
A correct IP address for the U-PROX IC A controller must be specified
The anti-passback software settings in U-PROX must be correctly applied

Check these settings!!!

Also:

or “Lost connection to anti-passback controller”

In the door parameters, “Global Anti-Passback” may need to be enabled

After loading the U-PROX IC A controller, if you select it in the software (in the “Object Panel” window), the pane on the right should display the number of loaded cards

Immediately after loading the U-PROX IP400 and U-PROX IC A controllers, on the first passage through each U-PROX IP400 controller, you will see either:

“Restored connection to anti-passback controller”

Reflection of the work of the “global anti-duplicate” in the U-PROX software

ABSENCE of global anti-duplicate: – after receiving such a sequence of events, there will be a 3-second delay, and subsequent events of INCORRECT passage will simply be “Anti-duplicate” (local).

PRESENCE of global anti-duplicate: – after receiving such a sequence of events – everything will be fine, and further events of INCORRECT passage will have the message “Global anti-duplicate”

For configuration, refer to the standard document in the “…\Documentation” folder (of the installed U-PROX software, or on the installation disc or in the U-PROX installation package) – Configurator.pdf. It is also available on the website https://access.u-prox.systems/uk/ under “Downloads” → “Software and Manuals.”
