2N® Access Unit

Einfach installierbares Zutrittssystem

Die 2N® Access Unit ist ein zuverlässiges Zutrittskontrolsystem , welches die IP Technologie nutzt. Bereits auf den ersten Blick besticht sie durch ihr repräsentatives Design und erfreut durch ihre Einfachheit. Sie besteht aus einem autonomen IP Lesegerät für RFID Karten, der auch die NFC-Technologie unterstützt, und bildet mit der Kontrollanlage eine kompakte Anlage. Es genügt, sie an Ihr LAN-Netz anzuschließen und danach alles einfach über die Webschnittstelle einzustellen. Die 2N® Access Unit bietet somit ein ausgezeichnetes Preis-Leistungsverhältnis und ist eine ideale Lösung für kleine und mittlere Firmen.


IP RFID und NFC-Kartenleser 2N® Access Unit verbinden alle standardmäßig genutzte Anlagen, wie klassische Kartenleser, Türkontrollanlagen und IP-Wandler in einer Anlage. Dank dieser Tatsache wird nicht nur die Installation, sondern auch der Betrieb des Zutrittssystems erheblich vereinfacht und kostengünstiger gestaltet.


Die Anwendung von Türsprechanlagen und Lesegeräten von 2N ermöglicht es uns, die wachsenden Anforderungen der Kunden zu befriedigen. Darüber hinaus erfordern sie keine aufwändige Installation und Einstellung. Es ist von Vorteil, dass alle Türsprechanlagen von 2N und alle neuen Lesegeräte 2N® Access Unit über gleiche Einstellungen verfügen und leicht fernverwaltet werden können.

About the 2N Helios IP USB driver

This driver allows:
- Enrolling of RFID cards from 9137421E External RFID Reader 125kHz + 13.56MHz (USB interface) directly to web interface of 2N Helios IP and 2N Access Unit.
- Enrolling of users into Bluetooth access control. Users need to have 2N® Mobile Key on their smartphones and Bluetooth reader on their device.
- Enrolling of users for access control using the fingerprint.

Compatible cards:
HID Proximity

13.56MHz - (only card serial number is read)
Mifare Classic 1k & 4k, DESFire EV1, Mini, Plus S&X, SmartMX, Ultralight,
Ultralight C, SLE44R35, my-d move (SLE66Rxx), PayPass, Legic Advant
Calypso, CEPAS, Moneo, SRI512, SRT512, SRI4K, SRIX4K, PicoPass, HID iCLASS (uID)
SmartPhone with NFC/HCE support, Android version 4.3 and up, 2N Mobile Key application

PC requirements
Win 7 or 8, 64bit
2N® Network Scanner version 3.0.4

- 2N® Network Scanner can find devices without IP address
- 2N® Network Scanner can set basic network settings - DHCP on/off and set static IP address (same requirements as above) - units with this feature enabled and disabled are distinguished by color (grey ones can not be configured).
- 2N® Network Scanner can also locate devices in other network segments, if multicasts are routed between them
- Filtering in results
- Name change from 2N® Helios IP Network Scanner to 2N® Network Scanner as it is also able to find 2N® Access Unit and 2N® Indoor Touch

Location of devices without assigned IP address and network settings do work with 2N Helios IP intercoms, 2N® Access Unit and SIP IP audio with firmware version 2.15.0 and higher. This feature does not work with 2N® Indoor Touch version 1.6 and 2.0, however these devices are still located in the network with assigned IP address.

Valid as of 14.8.2015
Version 2.19.0 includes the following changes:

User Functions and Innovations
• Silent alarm – intercom user security enhancing function. Upon activation, the code higher by 1 than the common access code starts silent alarm.
• Limitation of unsuccessful access attempts – the keypad access gets blocked when five invalid access codes are entered via the keypad. This minimises the risk of unauthorised access through simple code entering attempts.
• Enhanced directory search.
• Holiday list extended for the next 10 years.
• Apply button renamed into Save.
• As innovation, you can set the switch activation time to a value lower than 1 second.

• Stability issues when sending an email
• When a switch was using a Security Relay and was controlled by time profile, it did not keep its state after reboot
• Stability issues when connecting new modules to Verso and Access Unit models
Version 2.18.1 includes the following changes:

System Functions and Innovations

Final function and function setting improvement for the VersoBluetooth module under preparation.


Access Unit stability enhancement.

Version 2.18.0 includes the following changes:

User Functions and Innovations

Security Relay has a new code and thus has to be re-paired after hardware factory reset.

Features - system changes

* No restart necessary after change of configuration
* HTTP API event logging - all events to include UTC time plus timezone
* Support for 2N® Network SCanner 3.0.x - this version can detect Access Units without IP address and configure DHCP on them (typically assign static IP address)
* Upgrade prompt - if we introduce some radical change in firmware in the future, old firmware will warn the user while the new one being applied, so that the user can abort the upgrade when not sure he wants these changes.
* Collection of anonymous statistic information - in order to have better feedback on use of our products we will gather statistics of device usage. User can manully disable this in web configuration.
* Support for automatic event notification to 2N® Access Commander - tamper switch activation, door opened too long, forced door open, web unsuccesfull login attempts.

* HTTP(S) Autoprovisioning authorisation support
* Timezones according to tzdata - more timezones to choose from
* Card selection on RFID card reader - you can restrict which RFID types are supported by the readers. This does not only enhance security, but also improves reading performance of the reader. Default value is that the reader reads all supported types and we recommend restricting this to only those types which are really used.
* "Custom response" option on HTTP API - when sending HTTP command to Helios IP you can specify what answer you want to receive, including an empty answer.

Known issues

* Need to refresh browser after upgrade - this is caused by new certificate used

Version 2.14.1 includes following changes compared to 2.14.0

Failsafe lock support - new option "Iverted" for lock type in switch settings
Support for Network Scanner 2.2.x to discover units without IP address and do basic network settings.
Logging in HTTP API - replaces old Event Logging service which is kept for back-compatibility but not maintained anymore.
NTP client enabled by default - Access Unit shall update the time information automatically by default
Additional parameters for TR069 provisioning
Support for extending I/O module connected to Access Unit via Vbus
Support for connected keypad to Access Unit via Vbus


Possibility to send HTTP commands once the switch is activated or deactivated
Modifications in Automation - some parameters didn´t work properly (Condition.FlipFlopRS, Event.MulticastTrigger, Condition.LogicalAnd, etc.)

Another minor bugs in Automation in comparison with FW 2.13.3


Ready for 125kHz Access Unit - possibility to use this FW version also for new version of Access Unit (125kHz) which will be launched during July, 2015.
TR069 protocol - support for protocol for provisioning. Support includes basic statistic information and config file handling. Particular parameters will be accesible in next versions.
Event log in web interface - log displayed in Status section contains much more information. Filtering is available as well.
Support for future hardware modules (e.g. finger print reader)
If no extender is connected then you can read a note (instead of blank screen)
Support for external USB card reader and its PC driver
Autoprovisioning now also accepts config files where the filename includes MAC address of Access Unit without "-" between fields. So if it does not find hau-00-87-12-aa-00-11.xml, it tries au-008712aa0011.xml.
Serial number shown on licence page, for convenience when requesting and checking licence
