Basic Features
2N Access Unit M is an elegant and reliable access IP system equipped with a number of useful
functions.
2N Access Unit M is a single-module access system available in several versions.
All the 2N Access Unit M versions include an integrated card reader module, which helps
control access using an RFID card. With additional software settings, you can use the card to
control more functions than just door lock switching too.
The 2N Access Unit M keypad versionhelps you control the electric lock switch by entering a
valid numeric code via the numeric keypad. With additional software settings, you can use the
numeric code to control more functions than just door lock switching too.
The 2N Access Unit M Bluetooth version helps you control the lock switch using the 2N
®
Mobile
Key application installed in your smartphone.
2N Access Unit M is designed as a robust, mechanically resistant IP55-rated access system,
which withstands any weather conditions without requiring additional accessories.

PoE Supply
2N Access Unit M is compatible with the PoE 802.3af (Class 0–12.95 W) technology and can be
supplied directly from the LAN via compatible network elements. If your LAN does not support
this technology, insert a PoE injector, Part No. 91378100, between 2N Access Unit M and the
nearest network element. This power supply provides
2N Access Unit M with 12 W for its own feeding.

Security
The 12 V output is used for lock connection. If, however, the unit (2N IP Intercom,
2N Access Unit) is installed where unauthorized tampering may happen (building
envelopes), we strongly recommend that Security Relay (Part No. 9159010) be
used for enhanced installation security.

2.4 Extending Module Connection
The Security Relay (Part No. 9159010) is used for enhancing security between the access unit
and the connected electric lock. It significantly enhances security of the connected electric lock
as it prevents unlocking by forced opening of 2NAccess Unit M.
Function:
The Security Relayis a device installed between the access unit (outside the secured area) and
an electric lock (inside the secured area).The Security Relay includes a relay that can only be
activated if a valid access card is detected by the unit.
Specifications:
Passive switch: NO and NC contacts, up to 30 V / 1 A AC / DC
Switched output:
Where the security relay is fed from the intercom, 9 to 13 V DC is available on the output
depending on the power supply (PoE: 9 V; adapter: source voltage of minus 1 V) / 400 mA
DC.
Where the security relay is fed from an external power supply, 12 V / 700 mA DC is available
on the output.
Dimensions: (56 x31 x 24) mm
Warning
When you connect a device containing a coil, such as a relay or an electromagnetic lock,
it is necessary to protect the access system output against voltage peak while switching
off the induction load. For this way of protection we recommend a diode 1 A / 1000 V
(e.g., 1N4007, 1N5407, 1N5408) connected antiparallel to the device.

Weight: 20 g
Installation:
The Security Relay is installed onto a two-wire cable between the access unit and the electric
lock inside the area to be secured (typically behind the door). The device is powered and
controlled via this two-wire cable and thus can be added to an existing installation. Thanks to its
compact dimensions, the device can be installed into a standard mounting box.
Connection:
Connect the Security Relay to the access unit as follows:
To the Active output
Connect the electric lock to the Security Relay output as follows:
To the switched output.
To the passive output in series with an external power supply.
The device also supports a Departure button connected between the ‘PB’ and – Helios/2N IP
intercom’ terminals. Press the Departure button to activate the output for 5 seconds.
Status Signaling:
Green LED Red LED Status
flashing off Operational mode
on off Activated output
flashing flashing Programming mode – waiting for
initialization
on flashing Error – wrong code received
Configuration:
Connect the Security Relay to the properly set access unit security output.Refer to the
2NAccess Unit Configuration Manual. Make sure that one LED at least is on or flashing.
Press and hold the Security Relay Reset button for 5 seconds to put the device in the
programming mode (both the red and green LEDs are blinking).
Activate the output switch using the keypad, telephone, etc. The first code sent from the
intercom will be stored in the memory and considered valid. After code initialization, the
Security Relay will pass into the operational mode (the green LED is blinking).
