Basic Description
2N Lift8 ®( ) is a communication system with a function similar to an intercom. TheL8
system voice audio units are linked to a common bus (pair of wires), connected to a
splitter. The splitter is always connected to a central unit (CU), which controls the
system operation and provides connection with the control centre. It is possible to
connect up to 40 audio units to the bus. The CU contains an internal splitter.
Each splitter is uniquely identified: by lift number 1 to 8. The audio units are connected
to the splitters and located on the shaft bottom, in the cabin interior, on the cabin roof
and in the machine room. The machine room can be shared by multiple lifts.audio unit
The contains an easily replaceable backup battery pack (lead rechargeable battery). CU
The is responsible for battery charging and status monitoring. It indicates theCU
charging state, signal strength, telephone line state, bus state core state via five colour
LEDs. It is also equipped with a USB interface for comfortable configuration, voice
message recording and software upgrade.
The can be connected via: GSM, UMTS, PSTN or VoIP. CU

With special cables (to the cabin), use the neighbouring wires and
make sure that the nearest surrounding wires do not radiate
interference (power wire, video signal etc.).
Tip
Do not lead the bus close to power cables, especially in long-distance
sections.
Branch the bus to shorten the total length of sections.
Safety
The bus is electrically isolated from the telephone line circuits according to
the EN60950 standard requirements and its low voltage cannot cause any
electrical accident.

CU Connection to Telephone Network
You can connect the to any of the following telephone networks: CU
PSTN
PBX
GSM
UMTS
VoIP
PSTN
works in a broad band regardless of polarity and line parameters (refer to 2N Lift8
®
Technical Parameters). Connect it using the enclosed cable with an RJ–12 terminal. It
is the most reliable and simplest connection. The disadvantage is the operating cost
(fixed fee).
Caution
Only one may be connected to one telephone line and no other endCU
telephone equipment may be connected to the line including a product
through which the telephone line goes (so-called priority connection –
electronic burglar alarm, e.g.).
No dual or party lines may be used.
No telephone “multiplugs” (adaptors), even the smart ones, may be used.
Never connect to an ISDN line.2N Lift8
®
®
342N TELEKOMUNIKACE a.s., www.2n.cz
Telephone line requirements
The line must not be a dual or party one.
The telephone socket and its wiring are usually the network provider's property
and may not be tampered with.
Other recommendations
Notify the telephone network provider of your installation and submit2N Lift8
®
certification upon request.
Your follow-up wiring must comply with the relevant safety regulations.
You are recommended to secure your cabling against pirate connection (with a
telephone lock, e.g.).
Connection via PBX (Private Branch Exchange)
This is the least-cost solution where a PBX and an unused PBX line are available.
PBX line requirements
The PBX to be used must work reliably even in the case of power outage. Large
PBXs are mostly equipped with a back-up power supply, smaller PBXs usually use
PSTN line redirection in the event of power failure. Consult the problem with the
technician responsible for your PBX. An error during power outage may result in
calling an undesired station.2N Lift8
®
Relevant call access rights have to be assigned to the PBX line to be used (use a
standard telephone set to check whether the line can make outgoing calls to all
the required numbers).
While programming, enter the necessary PSTN code (typically a zero), or
(preferably) make the PBX not require a prefix (so-called automatic connection to
the provider's telephone line).
To make the control room – lift calls, you have to know the extension number
and how to get through to it (dial-in, DISA, operator).
The control room – lift connection may not depend on the operator’s presence;
no call forwarding to a fax/answering machine in the night mode is allowed, etc.
Other recommendations
Make an agreement with the PBX owner regarding operating costs (2N Lift8
®
outgoing calls are billed at the owner‘s expense with the exception of free calls
via “green lines”).
GSM
This is used in particular where no PSTN line is available.
Tip
If there is permanent manning in your building (security staff,
receptionist), train the personnel how to rescue people and program 2N
®
to call this service. Lift8

Recommendation
In places with a poor signal quality find an appropriate place or use a special
(directional) antenna.
Protect the SIM card from theft.
If a prepaid SIM card is used, make sure that the credit is monitored and
topped up in time.
UMTS

(within the available 1m cable) does not matter.
The microphone must be stuck on so that it does not pick up (even in part!) the
acoustic pressure from the space behind the control panel. Such sensing might
result in acoustic feedback since the speaker strongly radiates sound into the
cavity.
Separate Speaker Mounting
The speaker is equipped with a cable and can be separated from the electronics (simply
pulled out) within the reach of the cables delivered (1m). This option is useful where
there is not enough space for the whole electronic equipment. Fit the speaker
according to the instructions below:
While gluing the speaker choose such procedures or adhesives that prevent
membrane damage by adhesives and volatile substances or heat.
We recommend you to keep the speaker sealed to eliminate vibrations and
provide electrical insulation.

ALARM Button Connection
Requirements
The ALARM button design (colour, symbol, keypad surface, mechanical operation)
and location have to meet the requirements of the particular installation.
Button control
Requirements
The ALARM button has to be equipped with a make or break (NO/NC) contact
that is not connected with any other circuit.
None of the ALARM button terminals may be connected electrically with any other
electrical circuit and no voltage source other than the NO/NC contact may be
connected to them.
If one of the ALARM contacts is connected to another circuit, an appropriate
isolation strength according to the applicable standards has to be ensured
between the contacts.
Procedure
Leave the ALARM terminal in the lower position (3).
If you use a make contact, leave the jumper as it is (5th pin on jumper 12) –
ALARM without jumper fitted (factory setting).
If you use a break contact, fit the jumper (5th pin on jumper 12) – ALARM

Voltage control
Requirements
DC 12 to 48V voltage
The voltage signal must be active even during a power failure.
Procedure
Move the ALARM terminal two pins up into position (2).
For activation by voltage connection, leave the jumper as it is (5th pin on jumper
12) – ALARM without jumper fitted (factory setting).
For activation by voltage disconnection, fit the jumper (5th pin on jumper 12) –
ALARM inverted – jumper fitted.
CANCEL Input Connection (Door Contact, Optional)
This input helps cancel a rescue request if the lift is fully functional. When the ALARM
button is pressed, the system waits for a pre-programmed period of time, which is a
little longer than the maximum lift running time. If the lift is functional, it arrives in the
required station within this timeout and opens the door. In that case, the rescue
request is cancelled. If the door does not open, the request is accepted.
Find out before installation whether the door opening signal is available in the lift cabin.
Requirements
If the lift has a double door, the signal must be active only if both the door sets
are open, i.e., if it is really possible to leave the cabin.
The door position signal has to work even in the case of power outage.
Contact control
Requirements
None of the contact outlets terminals may be connected electrically with any
other electrical circuit and no voltage source other than the NO/NC contact may
be connected to the CANCEL terminals.
Procedure
Leave the CANCEL terminal in the lower position (5).

Figure: Cabin Audio Unit – Universal Mounting Hole Dimensions
To mount the unit, you need 4 electrically spot-welded (from the inner panel side) M3
or screws, a sufficiently perforated speaker area and a microphone hole. If needed,M4
a high-quality double-sided foam self-adhesive tape can be used for installation on a
perfectly degreased surface.
Warning
Leave no gap between the lift control panel and the audio unit surface to
avoid acoustic speaker fault and acoustic speaker-microphone feedback.
this type of audio unit Do not use otherwise than mounted on a
sufficiently large board. The acoustic properties of an uninstalled audio
unit cannot be guaranteed.
®
852N TELEKOMUNIKACE a.s., www.2n.cz
Separate Microphone Mounting
If the microphone is supplied separately on a 25×25 mm large board with
self-adhesive foil and with a cable, you can mount it easily behind any hole in the panel
(keep the minimum hole diameter of 5 mm or a group of smaller holes of the same
total area). Just glue the microphone directly onto the required place from behind (be
sure to degrease and clean the surface carefully before mounting!).
Requirements
The minimum distance between the speaker and microphone centres is
90 mm. A lower distance may lead to acoustic feedback. A greater distance
(within the available 1m cable) does not matter.
Make sure that the glued-on microphone does not pick up (even partially!) the
acoustic pressure from the space behind the panel. Such sensing might result in
acoustic feedback since the speaker strongly radiates sound into the cavity
Separate Speaker Mounting
The speaker is equipped with a cable and can be separated from the electronics by
simply being slid out within the reach of the cables delivered (1 m). This option is
useful where there is not enough space for the whole electronic equipment. Fit the
loudspeaker according to the instructions below:
While gluing choose such procedures or adhesives that prevent membrane
damage by adhesives and volatile substances, or heat.
We recommend you to keep the speaker sealed to eliminate vibrations and
ensure electric insulation.
Frequently Asked Questions Concerning Speaker
Can I use a speaker of my own?
Yes, but keep the impedance of 64 Ω. Doing this, however, you assume
responsibility for sufficient volume and frequency range.
Can I use a longer cable for the speaker?
You can use a longer cable for the speaker, but not for the microphone.

Common Mounting Principles
Wall Mounting
Wall (surface) mounting is used wherever flush mounting is not applicable – in concrete
and steel structures, for example. The frame is not used.
Tip
Choose flush mounting where possible to make your product more
elegant, vandal-resistant and safer.
You can buy the flush mounting kit in advance and commission a
specialised firm to install the device. Moreover, the flush mounting kit
helps you level the audio unit properly (with a maximum vertical position
deviation of 2°).
Caution
Check the diameter of the plug holes. If the holes are too large, the plugs
may come loose! Use a building glue for fixing if necessary.
Check the depth of the plug holes! The plug length is 50 mm, the screw
length is 90 mm.
Do not use lower-quality plugs to avoid their pulling out of the wall!

®
different, lower-quality screws may lead to screw and surface corrosion!
Make sure that no impurities get into the device (especially on the sealing
and microphone sound guides) after removing the front panel.
Note
The microphone sound guides are loose after the front panel is removed.
This not a defect as the fitting screw only protects the guides against
falling out during installation.
Warning
Eliminate the risk of injury! Wall mounting is not suitable for narrow
passages and places where people pay attention to something else. The
manufacturer shall not be held liable for injuries caused by such
negligence!
Caution
Wall mounting is a problem where the device may be damaged by
vandals. In that case, use steel fitting elements instead of the plugs and
screws included in the delivery.
Seal all unused bushing holes with packings to avoid water leakage
(during wall washing, e.g.). Do not leave the holes open even for a short
time (between mounting and wire connection, e.g.).

Drill a hole using the template included for all
the necessary cables. Be careful while drilling
as this type of mounting does not allow to
balance rather great deviations later!
Unpack the frame, put the onto itaudio unit
and put this set on the hole to test whether
the hole is deep enough and its uneven edge
is completely covered by the frame.
Push or hammer the supplied plugs into the
holes. If the plugs are too loose, use a
mounting glue.
Remove the front panel from the audio unit.
Select the holes for the cables. Insert the
packings in the other holes. Use the cable
bushings or some sealing to avoid insect or
water penetration. Mount a small bushing into
the bottom hole too.audio unit
Put a frame on the .audio unit
Insert the in the hole and put theaudio unit
cables in at the same time. Leave a small
cable reserve inside keeping the excessive
cables under the bottom.audio unit
Insert the screw in the plugs in the holes on
both the sides. Tighten all theaudio unit
screws carefully. Caution: the screw
tightening sequence may affect the audio unit
position.
Seal the frame against the wall if necessary
with some silicon or other cement. Although
unnecessary for the function, theaudio unit
sealing helps protect the wall against
dampening due to water leakage.
Do not complete the mounting procedure until
you have connected the electricallyaudio unit
– refer to Electric Installation.
Flush Mounting – Thermally Insulated Wall
Cut out a hole in the insulation layer with the aid of the template (like with classic
bricks).
It is assumed that all the necessary cables lead to the predrilled hole. Now follow the
instructions for classic brick mounting yet respect a lower strength of thermally
insulated walls while tightening the screws.
Caution
As the hole depth depends on the insulation layer thickness, you may
need longer screws! If there are hollow bricks under the insulation layer,
the screws must be long enough to fill in the whole plug (50 mm)!
Otherwise, the plug will come loose.
Check the diameter of the plug holes. If the holes are too large, the plugs
may come loose! Use a building glue for fixing if necessary.
Check the depth of the plug holes! The plug length is 50 mm, the screw
length is 90 mm.
