Lift control – configure 2N systems to control lift access

You can setup 2N RFID/Keypad/Bluetooth/Fingerprint equipped IP units to control which floors authorized user can access.

The whole scenario allows interconnection of 2N IP units with AXIS A9188 I/O Relay Modules, which tells the lift which floor can be accessed after a person authorizes using the 2N IP unit as shown on the following image:

Types of most typical scenarios are:

  1. A 3rd party RFID card reader in the lift cabin is connected over Wiegand to a 2N Access Unit or located at the top of the shaft or in the Machine room. The 2N Access unit communicates over IP with the Axis A9188, which is connected to the Lift Controller. The Lift Controller uses CANbus (or similar) to control the buttons in the Lift Car.
  2. A 2N Access Unit or supported intercom is installed in the lift cabin requiring an Ethernet cable connection from the machine room. This is the most convenient scenario. The 2N device communicates again over IP with the AXIS A9188 in the same way as above.
  3. A 2N Access Unit or supported intercom is installed in the lift cabin, which does not have an Ethernet connection. 2N® 2Wire converters are used to bring IP connectivity and PoE through the Lift car’s traveling cable over available 2 wires. This provides IP connectivity for communication between the  2N device and the Axis A9188, which is linked with the Lift Controller.



Lift control solution requires:

  • (Optional) 2N® Access Commander 1.13 and later. Starting with 2N® Access Commander 2.0 you need at least an Advanced license for lift control.
  • 2N OS 2.27 and later. 2N® Access Commander 2.0 requires firmware 2.32 for compatibility.
  • Lift license (part of the Gold license - 9137909) for IP intercoms.
    The license is available for the following models: 2N® IP Style, 2N® IP Verso, 2N® IP Force, 2N® IP Safety, 2N® IP Vario.
  • AXIS A9188 I/O Relay Module (2N order no. 9160501, AXIS order no. SKU 0820-001) firmware or newer

Technical parameters

  • AXIS A9188 communicates with lift I/O Relay Module using its relays wired to lift system
  • 2N devices communicate with AXIS A9188 via IP protocol HTTPS
  • Time for relays open/close time is set by 2N IP unit to 10s (can be changed) which directly corresponds with time person have after his/her authorization on 2N IP unit to push floor button in the lift
  • One 2N device can connect to up to 8 AXIS A9188 I/O Relay Modules
  • Multiple 2N devices are not recommended to connect to same AXIS A9188 I/O Relay Module


The following guide will explain, how to set the whole scenario to allow a person access to certain floors in the lift using their credentials (RFID, Code, Bluetooth or Fingerprint).

Configure the 2N unit to communicate with the AXIS 9188 I/O Relay Module

  • Make sure the 2N device has Gold license (Lift feature included) installed and firmware 2.27 or newer is used.
  • Connect the 2N unit to the AXIS A9188 I/O Relay Module in section Hardware - Lift Control by specifying the IP address of AXIS A9188.

  • Make sure you fill in the authentication as well (admin credentials for the AXIS relay module - root/root by default).


    All AXIS A9188 I/O Relay Modules connected to the same 2N unit needs to have same administrator user with the same password (root for example) - maximum of 8 AXIS A9188 I/O Relay Modules can be connected to one 2N unit allowing for a maximum of 64 floors

2N OS answering unit setup

2N answering unit support


All 2N answering units may be used for lift control, this includes even our most basic units such as 2N® Indoor Talk and 2N® IP Handset. More advanced answering units, such as 2N® Indoor View and 2N® Indoor Compact have an optional LIFT icon checkbox to make the lift button easier to identify; 2N® Indoor Touch 2.0 and 2N® Mobile Video will receive the LIFT icon functionality in the upcoming updates.

Basically, any device that can send DTMF may be used for lift control.

This setting is identical for 2NOS only and Access Commander included.

To configure a 2N OS answering unit, access the web interface of the unit. This unit needs to have devices corresponding with phone numbers of intercoms that are going to call it, in this example we’re using device:Verso, but you can use other syntaxes depending on network setup. Add a new device or edit an existing one.

The last step is to set up Unlock Buttons – as you can see, we set up separate ones for door control and lift control. If LIFT is checked, its icon will change to make it easier to differentiate between the two.

Once this Main entrance – 2N IP Verso device (whose device name is Verso) calls the Apartment 101 – 2N Indoor View user, the 2N® Indoor View recognizes it and shows the appropriate unlock buttons.

Tapping either of these will either open the door or start the lift action and send the HTTP request to the 2N device in the lift which then enables the appropriate buttons on the lift control panel via the Axis A9188.

It’s important to note that 2N® Access Commander serves as a synchronization server to make sure that the $CallUuid$ of the called user/device corresponds with the Uuid of a user in the 2N device that manages the lift. As this is an additional feature, you may still use this 2N device to enable lift buttons directly e.g. via Bluetooth or RFID.
