Outdoor spaces*, wall mounting
*) Outdoor spaces =
locations where the product is
exposed to rain or to water
running down the wall (e.g.
fence, outer wall). Mounting a
roof is obligatory in outdoor
spaces, unless the protection
against rain is provided for in
another way. Besides the roofs
presented herein, it is possible
to use roofs ref. no. 9135331E
and 9135332E

Notice: Do not fasten the boxes with plaster –they are designed for dry mounting

Mounting procedure
Cut a hole using the template on the reverse side of this instruction. If you work carefully
and do not exceed the tolerance of 5 mm, the frame will fully roof the edges of the cut
and there will be no need to fill it with plaster. As it is possible to cut a more perfect hole in
the plasterboard, it is advisable to make it 5 mm smaller: 105 (205) x 215 mm.
As to the plasterboard, it is advisable to cut the holes for each box like this:
Conventional wall: drill holes for wall dowels (Ø 8 mm) – use the template or directly the box. Insert the
dowels in the holes.
External insulation: Proceed as above. The dowels have to be fitted right in the wall; if the insulation
layer is thicker than 50 mm, longer screws are necessary, however, these are not a part of delivery. For
example, use 4.5 x 90 mm screws for 100 mm thick insulation.
Gypsum plasterboard: Do not use screws; the sides of the box are equipped with flippers.
Make a hole in the box to pull wires through (telephone, power supply,
electric lock etc.). When mounting more than two modules, make side holes
in the box to pull connecting cables through.
WARNING!!! This small cut (see the arrows) for the
microphone has to be on the LOWER side!!!
Only with roof:
Remove the protection sheet on the inner sides of the roof and
insert the countersink box. Then work with this unit.
Conventional wall, external insulation: insert the box (or box with roof) in
the cut in the wall and screw up. Before tightening the screws, adjust the sides
of the box vertically. We recommend to fasten the big box, ref. no. 9135352E,
with four screws ( holes in the corners of the box).
Gypsum plasterboard: Secure the box by turning the flippers (see the picture).
We recommend to protect the box from displacement with suitable glue (e.g.
silicon sealant. For plasterboard thicker than 12.5 mm, adjust the flippers or use
only glue.
Only with roof:
If you also mount the roof, seal its upper
and side edges to the wall; use silicon
sealant (see the picture).
Silicone
If the cut in the wall is not accurate and perfect, it is advisable to repair the edges with plaster.
Screws M4x10 mm attached to the bottom of the box are devised to mount Helios in the box.
Outdoor mounting rules - obligatory:
Always connect the backlight –it serves to equipment heating.
Water must not flow in along or around the cables.
Before closing the cover, carefully check all wires inside the cover for perfect closing
Remember to tighten both screws for mounting to wall
Make sure that all of the three loudspeaker holder feet fit into the board holes. A correct loudspeaker position is
necessary for a proper function of the seal.
Make sure that the silicone seal (tube on the upper face) is in place after installation.
Remember to tighten all of the four corner screws after electrical installation to make the loudspeaker seal fit
perfectly. Otherwise, water might get into the electronic part!
Caution
When the above mentioned precautions are not met, water might get in and destroy the electronics. It is
because the communicator 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!

Mounting - Completion
Remember to seal the 2N®Helios IP cable passage hole properly to avoid moisture in-leak and damage to electronics
due to condensation.
Make sure that the wires inside 2N®Helios IP are not squeezed and insert the plastic top cover (a transparent plastic mould)
carefully making its contacts plug into the electronics board connectors. Push the plastic cover into position moderately. If the part
swings over an obstacle or one corner is higher than the others, remove the cover and find the obstacle. Then tighten the corner
screws properly.
Mounting the metal cover follow the steps included in the subsection dedicated to name plate removal. Make sure that
the cover fits well and is perfectly flat. If its bottom part is loose, the mounting wall is probably uneven. Support the corners
to avoid 2N®Helios IP bending.
Caution
An improper mounting may significantly deteriorate the button function.
A poor outdoor mounting may cause water in-leak and damage to the electronics.
Most Frequent Mounting Errors
For illustration, a part of the plastic cover is removed in the figures below to reveal the sealed loudspeaker and the cover–
seal touch point. The cross section plane is marked white for better orientation.
Poorly tightened screw
(a squeezed wire has the same
effect)
WRONG
Gap between plastic cover and
loudspeaker seal
- water may leak in and damage
electronics

WRONG
Gap between plastic cover and
loudspeaker seal
- water may leak in and damage
electronics
If the loudspeaker support is in a wrong
position, the plastic cover may catch the
support brim (see the arrow) and, if
treated roughly, lead to component
deformations. Leakage may arise, see
the upper arrow.
Properly tightened screw
RIGHT
The seal touches the plastic cover. Water
flows out through a small hole (not
shown in the figure).
Note: Water does not affect the
loudspeaker Mylar membrane.
