Mountiong Type Overview
Refer to the table below for a list of mounting types and necessary components.
Flush mounting – classic bricks
(also hollow bricks, thermally insulated
What you need:
A properly cut hole
Plaster, mounting glue, mounting foam or
mortar as necessary
Flush mounting – plasterboard
What you need:
Just a properly curt hole
Wall mounting (concrete and steel
structures, entry barrier columns, etc.)
What you need:
Wall mounting box
Part No. 9153003
The warranty does not apply to the product defects and failures arisen as
a result of improper mounting (in contradiction herewith). The
manufacturer is neither liable for damage caused by theft within an area
that is accessible after the attached electric lock is switched. The product
is not designed as a burglar protection device except when used in
combination with a standard lock, which has the security function.
When the proper mounting instructions are not met, water might get in
and destroy the electronics. It is because the intercom circuits are under
continuous voltage and water infiltration causes an electro-chemical
reaction. The manufacturer’s warranty shall be void for products damaged
in this way!
Common Mounting Principles
Select flush mounting where possible to make your product elegant
looking, more vandal resistant and more secure.
Stainless steel screws are used for the 2N
Helios IP Uni assembly. Other
screws than stainless steel ones corrode soon and may aesthetically
deteriorate the surrounding environment!
Having removed the front panel, make sure that no dirt gets inside the
product (especially onto the sealing surface).
– Classic Bricks
1. Cut a wall hole using the template enclosed. Make sure
that all the required cables are available in the hole.
2. Unpack the plastic mounting box. Break out the cable
holes as necessary and make sure that the wall hole is
big enough for the box.
3. Wall up the mounting box making sure that the box is
aligned with the wall surface. Wait until the plaster
(mortar, mounting foam, etc.) sets.
4. Unscrew the front panel from the door intercom.
5. Connect the cables to the terminals or RJ connector as
described in the Electric Connection subsection.
6. You can use the cable tie for connection as shown:
Suggested cable fixation
Mounting completion – after electric installation!
7. Insert the intercom in the mounting box in the wall.
8. Tighten the intercom with the stainless steel screws included in the delivery. As the
screw holes are oval, you can perfect the vertical position before tightening.
9. We do not recommend you to insert the button tags now.
10. Replace the stainless steel front panel fixing it with the stainless steel screws you
unscrewed in step 4 above.
If this is your first plasterboard installation, check the
function of the intercom side clamps. Loosen and then
re-tighten the clamp screw to see how it turns
automatically and starts moving forwards in its slot.
Remember to return the clamp into the original position
after the check!
Check the plasterboard wall and room interior pressure
values (caused, e.g., by overpressure ventilation). If the
difference between the values is too great, separate the
intercom using, for example, the mounting box enclosed
and seal the cable passage to avoid loudspeaker
1. Cut a hole using the template enclosed (165 x 95 mm).
2. Unscrew the front panel from the door intercom.
3. Connect the cables in the hole to the terminals or RJ
connector as described in the Electric Connection
4. You can use the cable tie for connection as shown on
Mounting completion – after electric installation!
5. Insert the intercom in the hole keeping it in the vertical
6. Loosen the four clamp screws one after another and then
retighten them slowly. They will turn aside automatically and
start moving forwards in their slots. You need about 10
turns to tighten the clamps completely. You can perfect the
vertical position before final tightening of the screws.
7. We do not recommend you to insert the button tags now.
8. Replace the stainless steel front panel fixing it with the
stainless steel screws you unscrewed in step 2.
Use the wall (surface) mounting box, part No. 9153003, and follow the instructions
1.3 Electric Installation
This subsection describes how to connect 2N
Helios IP Uni into your Local Area
Network (LAN) and how to connect supply voltage and the electric lock.
Description of Connectors
12V/700 mA switched
RELAY1 Relay NO/NC contacts
TAMPER Tamper switch
POWER 12V/1A DC power input
Helios IP Uni is connected to the LAN via a RJ-45 terminated (connector X11)
UTP/STP cable (of category Cat 5e or higher). The system is equipped with the Auto-
MDIX function and so both the straight and crossed cable versions can be used
External Power Supply Connection
Helios IP Uni can be fed either from an external 12V/1A DC power supply or from
the LAN equipped with the PoE 802.3af supporting network elements.
External Power Supply
An external 12V power supply is connected to terminal block X19. Use a 12V +- 15%
DC power source dimensioned to current intake of 1A at least (Part No. 91341481E) to
ensure a reliable function of your device.
Helios IP Uni is compatible with the PoE 802.3af (Class 0 – 12.95W) technology
and can be supplied directly from the LAN via compatible network elements. If your
LAN in incompatible, insert the PoE injector, Part No. 91758100E, between
Helios IP Uni and the nearest network element.
Electric Lock Connection
Helios IP Uni is equipped with an electrically isolated relay switch with NO and NC
contacts (terminal block X17) and 12V/700mA switched output (terminal block X18),
to which a standard electric lock or another compatible electrical appliance can be
Tamper Switch Connection
Helios IP Uni is equipped with a tamper switch for detection of unauthorized
penetration into the device. After correct and complete installation of the device the
tamper switch is closed. Tamper switch opens immediately when the front panel is
removed. Tamper switch contacts are available on terminal block X18.
Helios IP Uni is equipped with a RESET button. Push the button for more than 10s
to reset the factory default values, deleting all the data stored in the device. Push the
button shortly (< 1s) to restart the device without changing its configuration.
– Insertion and Replacement
1.4 Button Tags
– Insertion and
1. Every name plate includes a piece of foil, which can be written over manually,
using a waterproof permanent marker.
Always use waterproof foil (enclosed or other) for the tags. Never use
paper or ink jet printing to avoid damage due to water leakage!
Tag Inserting / Replacing
Helios IP Uni provides an intuitive, easy
access to the name plates. The tags are easy
to insert and replace even without a manual.
You need not remove the front panel and
thus are not exposed to the risk of loss of
components while replacing the tags.
1. Loosen the name plate screw using
the wrench enclosed, for example.
You can open the name plate window
like a door without losing the
2. Remove the used or blank name tag
and insert a new tag.
3. Close the name plate window and
tighten the screw appropriately.
4. Check the click effect of the buttons:
if the button fails to click properly
when pressed (when moved by
approx. 0.5 mm), the tag is too thick
or thin. Make sure that the button
clicks when you press it on either

Helios IP Uni is switched into the dynamic IP address mode, i.e. it
obtains the IP address automatically if a properly set DHCP server is available in your
LAN. If no such DHCP server is available, you can operate 2N
Helios IP Uni in the
static IP address mode. Refer to the 2N
Helios IP Configuration Manual for
If your device remains inaccessible (you have forgotten the IP address, or the LAN
configuration has changed, for example), change the LAN settings using the buttons
on the device.
Static/Dynamic Address Setting Mode Switching
In case your 2N
Helios IP Uni device is equipped with 1 or 2 buttons, you can switch
the modes using one button only.
Helios IP Uni to the power supply (or, disconnect and reconnect
it if already connected).
Wait for the first acoustic signal .
Press button 1 fifteen times.
The acoustic signal
indicates mode switching.
Wait until the device is restarted automatically.
Note: The 15-times-1 sequence must be entered within 30 seconds after the first
sound signal for security reasons. The inter-digit delay may be 2s at most
The static IP address mode will be switched into the dynamic IP address mode and
vice versa upon restart.
If used frequently, 2N® Helios IP Uni gets dirty. To clean it, use a piece of soft cloth
moistened with clean water. We recommend you to obey the following principles while
Never use aggressive detergents (such as abrasives or strong disinfectants).
