Caution
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 damages 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
Tips
Select flush mounting where possible to make your product elegant
looking, more vandal resistant and more secure.
You can purchase the flush mounting box in advance and hire an
installation professional to make the basic installation work. Moreover, the
mounting box helps you align the intercom vertically (with a deviation of
up to 2°).
Caution
Make sure that the dowel holes have the required diameter. If the
diameter is too large, the dowels may get loose. Use some suitable
building adhesive to keep the dowels in place.
Make sure that the hole depth is sufficient too! The dowel length is 50 mm
and the screw length is 90 mm.
Remember that dowels of poor quality may easily get loose and fall out of
the wall!
Stainless steel screws are used for the 2N®Helios Force / Safety
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 and microphone sound
guides).
Note
The microphone sound guides are normally loose after the front panel is
removed! The screw is only used as a fall-out protection during
installation.

Wall Mounting
Wall (surface) mounting is used where flush mounting is inapplicable (in concrete and
steel structures, entry barrier columns, etc.). The frame is not used.
Caution
Wall mounting may be a problem where vandals may destroy the unit (in
public garages, e.g.). Therefore, use steel fixing elements instead of the
dowels and screws included in the delivery.
Be sure to insert plugs into unused bushing holes to avoid water leakage
during facade cleaning, for example. Never leave the holes open for even a
short time (one day delay between mounting and cable connection, e.g.).
Safety Warning
Eliminate the risk of accident! Wall mounting is not suitable for narrow
passages or places where people’s attention may be distracted. The
manufacturer shall not be liable for injuries incurred as a result of unsafe
mounting!
1. Select the 2N® Helios Force / Safety
position with respect to the supply
cables. Where the cables are installed
inside a structure or wall, use the hole
at the intercom bottom.
2. Drill holes of the depth of 70 mm for
dowels in the wall as shown in the
figure. Push or hammer the enclosed
dowels into the drilled holes. Use
some suitable building adhesive if the
dowels are too loose. Use fixing
elements of your own for steel
structure surface mounting (metric
screws + nuts, e.g.).
3. Remove the front panel from the
intercom. The electronic parts of the
two bottom buttons remain on the
panel in the four-name plate version.
4. Select the holes for cable supply.
Select and mount the bushings
depending on the cables: 2-hole
bushing or 1-hole bushing or both.
Insert the blanks in the other holes.
5. Put the intercom on the wall/structure
while introducing cables inside. Leave some of the cables inside the unit as a
reserve. Insert the plugs in the unused bushings and tighten the bushing nuts
carefully.
6. Do not complete mounting until you have finished electrical installation –refer to
Mounting Completion. Where cables lead along the surface, use the bushings
included in the delivery.

Flush Mounting –Classic Bricks
If you use the brick flush mounting box, follow the instructions included in the box. If
you do not use the mounting box, follow the instructions below:
1. Make a hole using the template.
Suppose that all the required
cables have been carried into
the hole.
2. Unpack the frame, put the
intercom inside and place the
set onto the hole to make sure
that the hole is deep enough
and the uneven edge is
perfectly covered with the
frame.
3. Push or hammer the enclosed
dowels into the drilled holes.
Use some suitable building
adhesive if the dowels are too
loose.
4. Remove the front panel from
the intercom. The electronic
parts of the two bottom buttons
remain on the panel in the four-
name plate version.
5. Select the holes for cable
supply. Insert the blanks into
the other holes. Apply the cable
bushings or a suitable sealant to
prevent penetration of insects
or water. You can also insert the
small bushing in the intercom
bottom hole.
6. Put the frame on the intercom.
7. Place the intercom into the hole
while introducing the cables.
Leave some of the cables inside
the unit as a reserve and the
rest under the intercom bottom.
8. Insert the enclosed screws in
the lateral mounting holes making sure they have penetrated into the dowels.
Tighten all the screws properly. Tip: The screw tightening sequence may affect the
intercom position.
9. You can seal the frame - wall gap with a silicone or another sealant to avoid wall
dampening as a result of water leakage. This additional sealing is unnecessary for
the intercom function.
10. Do not complete mounting until you have finished electrical installation –refer to
Mounting Completion
make sure that
the dowel holes are
drilled accurately!
You will not be able
to align considerable
inaccuracies with this
way of mounting!

Flush Mounting –Thermally Insulated Wall
Cut out the thermal insulation layer using the template (the same as for classic brick
wall).
Caution
The hole depth depends on the insulation layer thickness. If the insulation
layer is rather thick, you may need longer screws! If there are hollow
bricks under the insulation, make sure that your screws pass through the
whole dowel (50 mm) and fix the dowel reliably.
Make sure that the dowel holes have the required diameter. If the
diameter is too large, the dowels may get loose. Use some suitable
building adhesive to keep the dowels in place.
Make sure that the hole depth is sufficient too! The dowel length is 50 mm
and the screw length is 90 mm.
Suppose that all the required cables have been carried into the drilled hole. Now follow
the instructions applicable for classic brick flush mounting. However, remember that
thermally insulated walls show less strength than classic brick walls.
