®2N Helios IP ®
and higher. It significantly enhances security of the connected electric lock because it prevents the lock from
opening by forced intercom tampering.
Function:
The is a small device installed between intercom which is placed Security Relay2N Helios IP
®Helios IP2N ®
outside the secured area and the electric lock installed inside the secured area. The interconnection scheme is
shown in the picture below:
The includes a relay that can only be activated if the valid opening code is receivedHelios IP Security Relay2N
®
from the intercom.
Specifications:
Passive switch: NO and NC contacts, up to 30V/1A AC/DC
Active switch output: typically 8 – 13 V DC depending on power supply (adapter: input voltage minus
0.6V), max 700mA
Dimensions: 56x31x24mm
Weight: 20g
Installation:
Install the onto a two-wire cable between the intercom and the electric lock inside2 Helios IP Security RelayN
®
the area in order to be secured (typically behind the door). The device is powered and controlled via this two-wire
cable and so it can be added to an existing installation. Thanks to its compact dimensions the device can be
installed into a standard mounting box.
Settings for the Helios IP Vario:
The settings are the same as described below, but in addition you need to change the jumpers on the
configuation connector on the PCB to position and Lock Power Supply settings can be set eithernormally OPEN

external or internal. Then, after setting of the Security mode, the relay is powered and works correctly. These
jumper settings aredescribed in the 2.3 Electric Installation
Connection:
Note: Keep in mind the polarity (see the picture below)
Connect the to the intercom as follows:Helios IP Security Relay2N
®
To the intercom active output (OUT1 or OUT2) , or
To the intercom relay output with a 12 V DC serial external power supply.
Connect the electric lock to the output as follows:Helios IP Security Relay2N
®
To the active 12V/700mA DC output, or
To the relay output with a serial external power supply.
The device also supports a Departure button (you can use our own – order Helios IP Departure button2N®
number is 9159013) connected between the "PB" and "– HeliosIP" terminals. When you press the departure
button, you will activate the output for 5 seconds.
Status signalling:
There are two LED diodes placed in the . In the table below you can find what does itHelios IP Security Relay2N

Activate the intercom switch by 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 Helios IP Security2N

will pass into the operational mode (the green LED blinks).Relay
After these steps you can be sure that nobody will be able to open the door with 12V battery placed between 2N
intercom and security relay as shown in the picture below. Helios IP

Security relay is programmed in a such way that it needs to receive special signal (code for door opening) and
only after that it activates the output (active or passive) to which is connected the electrical lock. Without this
specific signal you will never open the door.
