Module Bus Interconnection

All the modules that can be connected to 2N Access Unit are interconnected via a bus. The bus starts on the basic unit and goes over all the modules. The order of modules on the bus is irrelevant. And it also irrelevant which bus connector on the module is used as the input and which is used as the output.

The modules include a 220 mm long bus interconnecting cable; Part No. 9155037 Wiegand modules and Part No. 9155034 I/O modules include an 80 mm long bus cable. These two modules can be hidden inside one of the modules described below (Infopanel, Keypad, RFID card reader, Bluetooth) and/or placed freely behind a standalone access unit (in a mounting box, e.g.).

It is possible to order separate bus cables of the lengths of 1 m, 3 m, or 5 m (Part Nos. 9155050/9155054/9155055), which are designed for remote 2N Access Unit module installations. Typically, they are used for an RFID card reader mounted on a wall opposite to the 2N Access Unit installation. The cable may be used only once on the bus. In extensive installations, the total bus cable length may not exceed 7 m.

Module Power Supply

All the modules connected to 2N Access Unit, except for the Tamper Switch, are powered from the bus. The available bus power output depends on the power supply type. The basic unit can use a 2 A power supply to increase the bus power available to the modules connected.

Power supplySpecificationAvailable power output
External supply12 V ±15% / 1 A12 W
PoE802.3af (Class 0–12.95 W)12 W

The count of modules on the bus is limited by the available power supply output. The maximum count of the modules on the bus is 30.

It is obvious from the specimen configuration that all the modules have sufficient outputs when an external power supply is used. When a PoE supply is used, the power output is insufficient for all the modules, which results in automatic decrease in backlight level, active output current supply, volume and LED intensity.

Some modules need a specific power output for their specific activities: the I/O module, e.g., requires 0.13 W for relay closing (not included in the minimum consumption).

2N® IP Security Relay

The 2N® IP 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 the 2N Access Module.

 

Function:

The 2N® IP Security relay is a device installed between the access unit (outside the secured area) and an electric lock (inside the secured area). The 2N® IP Security relay includes a relay that can only be activated if the valid opening code is received from the access 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 x 31 x 24) mm

Weight: 20 g

Installation:

The 2N® IP 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 so 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 2N® IP Security relay to the 2N Access Unit as follows:

To the active output (OUT1 or OUT2)

Connect the electric lock to the 2N® IP Security relay as follows:

  • To the switched output.
  • To the passive output in series with the external power supply.

The device also supports a Departure button connected between the ‘PB’ and ‘– HeliosIP/2N IP intercom’ terminals. Press the Departure button to activate the output for 5 seconds.

 

Status signalling

Configuration:

Connect the 2N® IP Security relay to the properly set access unit security output. For settings refer to the 2N Access Unit Configuration Manual is installed. Make sure that one LED at least is on or flashing.

Press and hold the 2N® IP Security relay Reset button for 5 seconds to put the device in the programming mode (both the red and green LEDs are flashing).

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 initialisation, the 2N® IP Security relay will pass into the operational mode (green LED flashing). 

Caution

In case of resetting the factory default settings on a device with a version of firmware 2.18 or higher, it is necessary to reprogram the
2N® IP Security Relay using the instructions above.
