Basic Description
2N® LiftNet (LN) is a communication system similar to the intercom. The audio units
are connected (through a pair of conductors) to a common bus, to which one central
unit (CU) is connected. The CU controls the system operation and provides connection
to the dispatching office. Up to 32 audio units can be connected to the bus.
Each audio unit is uniquely identified: by lift number 1 to 8 and position: shaft bottom,
cabin interior, cabin roof and machine room. The machine room audio unit can be
shared by multiple lifts.
The CU is supplied with 12V DC. It contains an easily replaceable back-up accumulator
battery pack (4 AA Ni-MH cells in a holder). The CU is responsible for battery charging
and status monitoring. It indicates the charging status, telephone line status and
current communication by means of three colour LEDs. It is also equipped with a USB
port to provide comfortable parameter setting, voice message recording and software
upgrade.

Before You Start
CU installation conditions
The CU is not designed for outdoor applications.
Do not mount the CU onto vibration-producing machines.
Install the CU vertically to allow air flow for cooling purposes (never cover the
CU with any cloth or install it in another closed box).
You may install the CU into the lift switching board unless the temperature
exceeds the acceptable limit.
The CU may be operated in the lying position on a desk at the room
temperature of up to 25 °C.
Product Completeness Check
Check the product for completeness before installation please:
1 central unit
1 terminal – inserted on the bus connector
1 accumulator battery isolation tape is present (sticking out of the cover)
1 power supply adapter conforming 12V DC to the local power network
requirements
1 telephone cable with RJ terminals
2 wall dowels
2 dowel screws
1 manual, either in the printed or CD format
warranty certificate
Checking of Accumulators
Instructions
1. Completely pull out the tape that sticks out of one opening on the back side of
the CU. This tape protects the inserted accumulators against discharging
during storage. With this tape it is possible to store the product (if supplied
including batteries) ½ year since the shipping date, which is indicated on the
packaging. After this period the claims, if any, regarding the battery warranty
cannot be accepted.
2. Do not connect anything to the CU and if any control lamps light up after the
tape has been removed wait a few seconds until they turn off.
3. Now watch the “power” control lamp on the CU carefully for a few seconds (not
in direct sunlight because the flashing is not strong):
21
PSTN Central Unit
2.1
a. Weak and short green flashing
The battery is OK and fully charged, you may continue with the
installation. If the product was stored for longer period than ½ year, or
under temperature exceeding 25 °C proceed according to paragraph b.
Caution
The product needs to be put in operation after the tape
has been removed.
It can be stored no longer than one week without charging; after having
been fully charged no more than 1 month.
b. Weak and short red flashing
Some battery cells are discharged. In such case connect the 12V DC
power adapter (do not connect any audio units!) and let the CU charge
for at least 24 hours, even after the indicator has starting showing that
the battery is charged. This is a so-called compensatory cycle, which
balances out the condition of the individual cells after a long period of
storage.
c. No flashing
The battery is fully depleted and may be damaged. Replace the battery
with a new recommended type (SANYO Eneloop 2000).
4. You may now install the CU.
CU Mounting
It is recommended to install the CU in a room that is secured against unauthorised
persons, such as the lift machine room, switching station etc. On an easily accessible
place there is a risk of telephone line misuse or SIM card misappropriation (in the GSM
version).
Mount the CU onto a wall using the attached dowels and screws.
CU Connection
Supply
Use the included adapter or a 12V DC power supply with appropriate parameters
(stabilised).
Warning
Never use an AC or non-stabilised DC power supply to avoid CU
damage.
22
PSTN Central Unit
2.1
Bus Connection
Requirements
With multi-wire cables, always use a symmetrical twisted pair of conductors
(i.e. those that match each other). Standard UTP cables contain twisted pairs.
With special cabling (in the cabin), use the adjoining cables and make sure
that the nearest neighbouring conductors do not radiate interference (power
cables, video signals, etc.).
Recommendations
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 Line
LN works in a wide range regardless of polarity and line parameters (refer to Technical
parameters). Connect it using the attached cable with an RJ-12 terminal.
Caution
One CU may be connected to one telephone line only and no other
telephone terminal equipment may be connected to this line.
2N
No double or group serial lines may be used.
No telephone “multiplugs”, even the “intelligent” ones, may be used.
Never connect LN to an ISDN line.
CU telephone network connection options
There are four connection options:
PSTN line
PBX line
®
LiftNet requires the telephone line exclusively for itself. This means
that NOT even a system through which the telephone line goes (priority
connection, ESS, e.g.) may be connected to this telephone line.
GSM gateway
VoIP adapter
23
PSTN Central Unit
2.1
Direct PSTN Connection
This is the simplest and most reliable type of connection. High operational costs (flat
rate costs) are a drawback of this solution.
Telephone line requirements
No double or group serial line.
The telephone socket including cabling is a property of the telecom company
and may not be tampered with.
Other recommendations
Notify the telephone network provider of your LN installation and submit
certification upon request.
Your follow-up cabling has to meet all applicable safety regulations.
You are recommended to secure your cabling physically against piracy (with a
telephone lock, e.g.).
PBX Connection
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 LN calling an undesired station.
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 calls to all
required „external”/CO line numbers).
While programming, enter all necessary PSTN prefixes (typically a zero), or
(which is a better solution) make the PBX not require a prefix (so-called
automatic CO line seizure).
To make dispatching office–lift calls, you have to know the extension number
and how to get through to it (dial-in, DISA, operator).
The dispatching office–lift connection may not depend on the operator’s
presence, no call redirection to a fax machine in the night mode is allowed,
etc.
Other recommendations
Make an agreement with the PBX owner regarding operating costs (LN outgoing calls
are billed at the owner‘s expense with the exception of free calls on “green lines”).
Tip
Where a non-stop security or porter’s service is available, the personnel
can be trained in rescue operations and LN can be programmed to call this
service.
24
PSTN Central Unit
2.1
GSM Gateway Connection (Temporary – Substitutes the GSM CU
Version, Part No. 501303E)
Used wherever no fixed telephone line is available.
Requirements
The GSM gateway has to be functional even in the case of power outage.
The GSM gateway has to recover its function without requiring the PIN.
Other requirements
Find a suitable place or use a special (directional) antenna where the GSM
signal quality is poor.
Secure the GSM gateway SIM card against misappropriation.
With a pre-paid SIM card, monitor the credit use and on-time replenishing.
VoIP Adapter Connection
This is the cheapest solution where a reliable Internet connection is available.
Requirements
The entire system has to be functional even in the case of power outage.
Other recommendations
As the VoIP technology is rather complicated, make sure that the dispatching
office personnel monitor connectivity reliably (evaluate the checking calls).
Tip
Some VoIP adapters have two independent telephone lines. A majority of
subscribers use just one line and the other line is thus available “free of
charge”.
Operation without Telephone Line
LN can be used as an intercom during lift assembly work even without a telephone
line. In that case, make sure that the lift blocking function is not activated until the
telephone line has been connected.
USB Port Connection
Recommendations
Do not leave a PC connected for a long time unless necessary in order to minimise risk
of PC damage due to HV shock from the telephone line during storms, e.g.
25

Interruption of Operation, Battery Maintenance
Caution
Never leave the batteries discharged for unnecessarily long periods.
If the battery is fully discharged please recharge it as soon as possible.
For a detailed description of situations that require your attention due to the state of
accumulators during interruption refer to the Maintenance section. Remember that
the state of accumulators is essential for system operation in any case. The
Maintenance section also contains instructions for accumulator maintenance, including
replacement.

Mounting Hole Dimensions for
Lift Cabin Audio Unit - Universa
Mounting
Main Board Mounting
This audio unit is mounted behind the lift control panel. Typically, the panel is ready
for installation as shown in the drawing below:
To mount the audio unit, you need 4 electrically spot welded M3 or M4 screws, a
sufficiently large loudspeaker perforation area and a microphone hole on the inner
(back) side of the panel. If needed, you can fix the audio unit on a perfectly degreased
surface with a good-quality two-sided foam self-adhesive tape.
Warning
Leave no gap between the lift control panel and the audio unit surface to
avoid acoustic loudspeaker fault and acoustic loudspeaker-microphone
feedback.
28
Lift Cabin Audio Unit – Universal
2.2
Do not use this type of audio unit in a position other than mounted on a
sufficiently large board. The acoustic properties of an uninstalled audio
unit cannot be guaranteed.
Separate Microphone Mounting
If the microphone is separated (connected by cable) it has a 25×25 mm large board
with self-adhesive foil. This helps you mount it easily behind any hole in the panel (the
minimum hole diameter is 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!).
Requirements
The minimum distance between the loudspeaker 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 loudspeaker strongly
radiates sound into the cavity.
Separate Loudspeaker Mounting
The loudspeaker is equipped with a cable and can be separated from the electronics
by simply sliding it 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
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 loudspeaker sealed to eliminate vibrations.
Frequently Asked Questions Concerning Loudspeaker
Is it possible to use a common loudspeaker for the communicator and floor
announcing machine?
No, it is not.
May I use a loudspeaker of my own?
Yes, but make sure that the impedance is 64 Ω. By doing this you assume
responsibility for sufficient volume and frequency range.
May I place the loudspeaker on the cabin ceiling?
This placement is not recommended.
May I use a longer cable with the loudspeaker?
Yes, but not with the microphone.

Figure 2.6 Address Setting for Lift Cabin
Audio Unit – Universal
Note
If external LEDs are connected to connectors 7 and 8, on-board LEDs 1
and 2 will not be shining.
Address Setting
The audio unit address means setting of two jumpers,
namely the lift number (1 to 8) and audio unit position
(refer to the cover drawing). If you install the audio unit
in the cabin of lift 1, you need not change the jumper
configuration. In other cases, follow the instructions
below:
Instructions
1. Release slightly the three screws on the
electronics cover.
2. Slide the cover to the right to expose the
jumpers.
3. Set the required changes as shown on the
electronics cover.
4. Replace the cover and tighten the screws.
Notes
Make sure that two audio units do not have an identical address to avoid
system error.
The position-setting jumpers are employed exceptionally, e.g. where a
certain audio unit type is used in a position other than normal.
To recover the initial address setting, follow the drawing on the cover.
Bus Connection
The connection polarity is arbitrary.
Warning
Connection to different, e.g. higher-voltage, cables leads to damage or
destruction of the audio unit.
Caution
The unit is powered via a 2-wire bus from the central unit. Unplugging of
the bus from the CU causes switching off of the unit.
Avoid the audio unit address duplicity.
31
Lift Cabin Audio Unit – Universal
2.2
ALARM Button Connection
Requirements
The ALARM button design (colour, symbol, button surface, mechanical run) and
location have to meet the requirements of the particular installation.
Button control
Requirements
The ALARM button has to be equipped with a normally open (NO) or normally
closed (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 a voltage source other than the NO/NC contact.
If one of the ALARM contacts is connected to another circuit, appropriate
isolation strength according to applicable standards has to be ensured
between the contacts.
Instructions
1. Leave the ALARM terminal in the LOW position (3).
2. With a normally closed contact, leave jumper (12) – right in the default
position.
3. With a normally open contact, switch jumper (12) – right into the HIGH
position.
Voltage control
Requirements
DC 12 to 48V voltage
The voltage signal has to be active even in the case of power failure.
Instructions
1. Switch the ALARM terminal by two pins up into position (2).
2. For activation by voltage connection, leave jumper (12) – right in the default
position.
3. For activation by voltage disconnection, switch jumper (12) – right into the
HIGH position.
Caution
Jumper setting, as printed on the unit cover of pre-production samples, is
only valid for CANCEL and wrong for ALARM.
See above for the proper setting.
Warning
Ignoring the instructions above may lead to product damage.
32
Lift Cabin Audio Unit – Universal
2.2
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 fails to open, the request is accepted.
Find out before installation whether the door opening signal is available in the lift
cabin.
Requirements
In double-door lifts, the signal has to be active only if both the doors open successfully
and let the people out.
The door position signal has to work even in the case of power outage.
Contact control
Requirements
None of the CANCEL terminals may be connected electrically with any other
electrical circuit and a voltage source other than the contact.
Instructions
1. Keep the CANCEL terminal in the LOW position (5).
2. With a normally open contact, leave jumper (12) – left in the default position.
3. With a normally closed contact, switch jumper (12) – left into the LOW
position.
Voltage control
Requirements
DC 12 to 48V voltage
Instructions
1. Switch the CANCEL terminal by two pins up into position (4).
2. For activation by voltage connection, leave jumper (12) – left in the default
position.
3. For activation by voltage disconnection, switch jumper (12) – left into the LOW
position.
Warning
Ignoring the instructions above may lead to product damage.
Note
Remember to program delayed calling to make the CANCEL connection
work successfully.

The basic configuration providing (using an external source) a sufficient illumination
intensity of indication elements is shown in the figure:
Requirements
The DC power supply has to be backed-up.
Notes
LN continues working except for the indicators during power outage.
The indication elements (bulbs, e.g.) may have the maximum current of
200 mA each.
Mind polarity in this case.
Alternative indicator connection (LED)
Today’s LED producing technologies help achieve a relatively good illumination
intensity at a low current supply. If a 5 mA LED (with diode loss of approx. 2V) is able
to provide efficient illumination in the lift, no power supply is needed. For this
configuration see the figure below:

The regulations that apply to communicator installations may require a mandatory
loop for persons with defective hearing in the lift cabin. In that case, connect the loop
to connector (10) with any polarity. The loop including a 1m long cable can be part of
your delivery if agreed.
Requirements
The induction loop has to be placed behind a non-metal, non-magnetic cover
in the control panel because the magnetic field of the induction loop cannot go
through the metal control panel.
The induction loop has to be labelled with an appropriate symbol (ear) placed
according to applicable standards.

Connect the wires before wall mounting. The connectors are separable – remove
them, connect the wires, tighten the screws and replace the connectors.
Mounting the audio unit from the outer lift cabin
wall is easier. In that case, no screws are
accessible from the lift cabin and the audio unit
cannot be stolen. If the cabin wall is accessible
from the outside, follow the instructions in item
a) or b). If not, follow item c).
a) If the lift cabin wall is thin (stainless steel
sheet), seek four 8 mm long M4 screws and fanshaped washers in the accessories.
b) If the lift cabin wall is thick (up to 20 mm
– laminated chipboard), seek four headless, 30
mm long M4 screws. Screw them into the unit
backside using the wrench included in the
delivery and tighten properly. Then push the
assembly through the pre-drilled holes, insert
the fan-shaped washers from the back and screw
in the nuts.

This section describes programming of 2N® LiftNet. It is possible to program 2N®
LiftNet in three ways.
PSTN Line Programming
Machine Room Telephone Programming
PC Programming
55
LN Programming
3.1
1. Remote (PSTN) telephone
programming
The access is password-protected. The voice menu is
in the national language.
2. Machine room telephone
programming
3. PC USB programming
Use 2N® LiftManager including the Service Tools.
Also, you can use the firmware upgrade, download of
language mutations and user-recorded message.
3.1 LN Programming
The advantage is that it is only the CU that has to be programmed. Thus, it is
unnecessary to re-program the parameters after audio unit replacement. With a
multiple-lift system, you just program one CU. The memory is independent of the CU
power supply.
To program the CU choose one of the following three ways:
PSTN Programming
Before You Start
Make sure that your telephone enables tone dialling (troubles may occur with
the so-called system/key telephones in some PBX systems).
Prepare a list of all parameters to be programmed in advance.
Make sure that, if LN is not entirely new, the service password is correct and,
if you are not quite sure of your LN configuration, execute full initialisation.
Caution
Remember to initialise the service password too!
Entering Programming Mode
You can enter the programming mode only during an incoming call (PSTN call to LN)
or upon line seizure by the machine room telephone.
To enable the programming mode press to enter services and after that enter the
service password in the format service password .
Note
Remember to enter an asterisk before and after the password!
If the password is correct, LN reports “You have entered the programming menu” and
displays a context-dependent help. The default password is 12345 and you have a 5second timeout by default (or a user-defined limit of 1 to 9 seconds) to enter every
character of your password. If you fail to keep the timeout, LN hangs-up.
56
LN Programming
3.1
Note
You are recommended to change it to secure your equipment against
unauthorised access.
If you forget your password, contact the manufacturer to recover your
data.
Programming Procedure
Having entered the programming mode, you can change any programmable value(s)
in any order. Proceed as follows: enter the function number and then the value. Use
an asterisk as a separator or Enter. In general, the function has the following format:
function number value
The function number has three digits (see the table). After you enter the function
number and an asterisk, LN reports the number or name, current value and potential
range of the parameter to be programmed. After you enter the value and another
asterisk, LN reports “Value stored”, or “Invalid value” if the value is beyond the
allowed range.
Warning
A drawback of some telephone sets is that, after you press a button, i.e.
send a DTMF signal, they go “deaf” for a fraction of a second. In that case,
you cannot hear the whole text and are recommended to use another
telephone.
Programming Error
If you make a mistake during entering (the function number or value) and have not
entered an asterisk yet, you can cancel the whole number by pressing and re-enter
the digits.
If LN rejects a parameter number or value you have entered, go on programming but
re-enter the function number even if it was the value not the number that was wrong.
If you have programmed and stored a value other than you intended to, you can reenter the value of course.
Programming End
Having stored all values to be changed, terminate programming by pressing . LN
sends a hang-up signal and hangs up. If you do not use the character, LN hangs up
later without affecting the stored values (the values are stored immediately after
being entered).
If you are not quite sure of LN’s programming behaviour, save the filled-in form for
later check.
Troubleshooting
LN fails to respond correctly to DTMF commands, e.g. the programming mode cannot
be entered.
57
LN Programming
3.1
Today, voice transmission is prevailingly digital, using variable compression
algorithms. Therefore, the DTMF signal to be transmitted is often distorted. Moreover,
it may, in some cases, be transmitted through the so-called command channel, whose
delay may differ from that of the speech channel.
Caution
Experience shows that, especially recently, it is practically impossible to
recover the DTMF signal in GSM networks
In such cases, try some other equipment (a digital PBX, e.g.) or the machine room
telephone set. If the machine room or PSTN programming attempts fail too, you have

4.2 Dispatching Centre Instructions
ALARM Call
1. The process starts the moment the ALARM button is pressed on any audio
unit. Upon the press, LN calls the dispatching centre (refer to Automatic
Dialling for details).
2. When the incoming call is answered by the operator, the LN voice message is
played identifying the calling lift.
3. The answered call must be manually confirmed first. This is done by button 1
on the dispatcher’s phone.
4. The call is time-limited (by the “Attention, the call is ending” message), but
can be prolonged using the button 4.
5. You are recommended to terminate the call by pressing button #.
Dispatching Centre – Lift Call
The dispatching office may call back to LN. The CU receives any incoming call
automatically, identifies itself and offers a voice menu (DISA). This helps the caller to
access the required audio unit. Like outgoing calls, incoming calls are time-limited and
easily controlled (prolongation, end).
Incoming call voice menu
The above mentioned menu helps you call the selected audio unit.
Notes
The machine room connection, however, is possible only if the connected
telephone has been picked up.
Number 9 is primarily used for LN configuration – refer to the
Configuration section.
Where the LN identification code is not stored, LN announces its
production/serial number.
70
Dispatching Centre Instructions
4.2
ALARM Call - Intercom
1. The process starts the moment the ALARM button is pressed on any audio unit
(except for the pre-set machine room – dispatching centre unit). Upon the
press, LN calls to the pre-set machine room – dispatching centre audio unit
(refer to Automatic Dialling for details).
2. When the incoming call is answered by the operator, the LN system voice
message is played.
3. The answered call must be manually confirmed first. This is done by button 1
on the dispatcher’s phone.
4. Then, the voice connection with the calling audio unit is activated.
5. The call is time-limited (by the “Attention, the call is ending” message), but can
be prolonged using the button 4.
6. Press 5 or # (or hang up, but this termination takes a longer time) to
terminate the call.
Caution
No alarm call can be made from the machine room audio unit set as the
dispatching centre. The alarm call is set to the audio unit that was the last
to activate the Alarm function. If no alarm was activated on any audio
unit, the machine room audio unit sets up no call.
If a call is set for a non-existent machine room audio unit, the alarm call is
not established (valid for settings #9, #0). If more numbers than one are
pre-programmed, the non-existent audio unit is skipped.
Alarm – Intercom setup. During the Alarm – intercom setup, there is
unilateral audibility between the machine room audio unit and the alarm
initiating audio unit at first and, when the call is confirmed, there is
bilateral audibility.
If you set #1 to #8 into the checking call memory (i.e. checking calls will
be set up to the machine room audio unit), it will be impossible to initiate
alarm from the set audio unit.
When the machine room audio unit - intercom is called, the voice message
for the dispatching centre is played to the calling unit too.
71
Dispatching Centre Instructions
4.2
Setting Machine Room Audio Unit Number
Enter # before the lift number to set the machine room number.
For example, 011 - #8 means that calling to lift 8 machine room audio unit is set in
ALARM button memory 1.
Setting options:
1. Service Tools – enter # and lift number into parameters
011-016.
2. Set the lift number into the button memory (011-016) in
the programming menu, select parameter 017 (refer to
the table of parameters) and enter the required character
(#) into the appropriate button memory.
Caution
The dispatching-intercom audio unit is set as lift 8 type machine
room by factory default.
You can set alarm-intercom for lifts 1-7 too. All you have to do is change
the lift address (jumper) and set another number into the ALARM button
memory.
The dispatching centre audio unit must be of the machine room
type and set as the machine room. If it is set otherwise (as a shaft,
cabin or roof), no call to the unit will be successful.
Note
It is possible to combine calling to the machine room (dispatching) audio
unit with calling via the PSTN.
To set up a checking call to a machine room audio unit, you can set the
number as described in the Alarm – Intercom subsection above.

Dispatching Centre Instructions
4.2
DTMF char
FUNCTION details
Only where automatic dialling repetition is enabled. The character is
used to confirm a successful call to LN. LN mutes the played-back
message and, optionally, sends the identification code (DTMF). The
call goes on until the timeout end and any of the following commands
may be used.
Voice module muting. CAUTION: Now this function is no more
necessary for calling due to a software change.
Repeated voice module playback, for 1 replaying of the message.
Call prolongation: The call is prolonged as defined in parameter 912
(120 seconds by default) in case it ended earlier without this
command. May be used repeatedly.
or
Call termination.
LN identification (without confirmation). This command is used by
automated workplaces. The LN sends the identification code.
The car audio unit is muted for 5 seconds during Alarm call (one-way
communication from operator / dispatcher to car). This feature is mainly
intended when big noise is in car (e.g. children crying) and operator needs to
communicate whole information to person in cabin.
to
These digits are reserved for other commands, e.g. „rescue
confirmation".
Tone Dialling Control during Call – Complete List of
Commands
Where automatic dialling with confirmation is used, it is possible to use tone dialling
for LN control during the call according to the table below. For simplification,
commands 1 to 5 are arranged in the sequence they are usually used in.
This table applies to the Automatic Audible Dialling with Confirmation mode.
Warning
Rarely, LN may not identify the above listed commands reliably during
message playing or voice communication. This is due to the essential
principle of the telephone line function where DTMF signalling is mixed
with the talk and thus may be hidden behind some speech tones or noise.
Hence, this phenomenon is not a defect of the product.
73
Fireman Function
4.3
4.3 Fireman Function
Intended for firemen’s actions, the Fireman function helps establish calls with the
highest priority. Connection is established between the Fire Station and the cabin
audio unit.
Description
The Fire Station is a universal cabin audio unit pre-programmed for the Fireman
function. Install the Fire Station into a place that is easily accessible by firemen.
The fire call has the highest priority, interrupting all the other calls (refer to the Call
Sequencing subsection). It is set up to the cabin audio unit in the shaft with the lowest
address (shaft number).
Press the button or turn the key to set up the fire call. The call time is indefinite.
Repress the button or return the key to interrupt the call.
A fire call setup is signalled by the fire station LED. Yellow light means the call setting
process and green light means a successfully set-up call.
If the machine room audio unit set as the dispatching centre is used, the green LED
starts flashing to indicate the fire call. Pick up the phone to enter the call. Hang up to
leave the call without interrupting the fire call.
Caution
The fire call has the highest priority and suspends all the other calls.
The fire call is set up to the cabin audio unit in the shaft with the lowest
address (shaft number).
Fireman is a licensed function. Contact your local distributor for details.
The fire station may be of the universal cabin audio unit type only.
Use
You can set up the fire call using a:
Button – press the button to establish connection with the cabin audio unit
and repress the button to cancel the connection.
Key – turn the key ON to establish connection and return the key into OFF to
discontinue the call.
Setting
Set the Fireman function using parameter 996 (format XY), where
X = the shaft number set on the Fire Station (1-8).
Y = activation this function with button (0), or key (1)

4.4 Function Description (for Advanced
Users)
Purpose of Section
The purpose of this section is to help technicians solve problems, if any. If the system
fails to work properly and a well-trained technician monitoring its operation step by
step according to the description included herein gets to a point where the description
and reality are in contradiction, he or she describes the contradiction, thus facilitating
troubleshooting. This procedure often reveals that the system works properly but the
user had a different idea of how to use it.
Outgoing Call
The process starts whenever the ALARM button is pressed on any audio unit. (in the
lift cabin audio units, the CANCEL input may delay or block calling, refer to parameter
914). After the ALARM button is pressed, the LN, LN establishes connection with the
dispatching office (for details see the Automatic dialling section). The LN replays a
message identifying the LN and the calling audio unit, as well as the following
instruction for the dispatching centre: “Press 1 for confirmation”. The received call has
to be confirmed manually or automatically. The call is time-limited (by the “Attention,
the call is ending” message), but can be prolonged.
For (DTMF) control during a call see the Dispatching Centre Instructions subsection.
Machine Room Call
You can call any audio unit in one LN system from the machine room (i.e. from the
machine room audio unit, item no. 913611, to which a telephone set is connected).
Furthermore, you can activate functions and program LN parameters with the machine
room audio unit. To activate the machine room audio unit, pick up the attached
telephone. Using the TRIPHONY button you can get through to the other audio units of
the same lift (however, if the machine room audio unit is shared by multiple lifts,
triphony is activated in the first lift only).

Hello! This is communicator ID number.../serial number...
Choose the lift number by pressing 1 to 8.
For connection with the cabin choose 1.
For the machine room choose 2.
For the shaft bottom choose 3.
And for the cabin roof choose 4.
Press 9 for services.
Enter the service password. Press 5 to end the call.
Triphony
Triphony provides interconnection of audio units. This mode can be activated by
pressing the TRIPHONY button in the machine room (see the preceding subsection), in
the lift shaft or on the lift cabin roof (audio units No. 913612E).
This mode features a different setting of the automatic HandsFree mode. The
microphones of active audio units are less sensitive than those operating in the ALARM
mode.

Checking Call
The checking call is an automatically generated outgoing call, typically established
every 3 days. The purpose of the checking call is to supervise the system function.
Typically, this call is processed automatically in the dispatching office.
Incoming Call
The dispatching office may call back to LN. The CU receives any incoming call
automatically, identifies itself and offers a voice menu (DISA). This helps the caller to
access the required audio unit. Like outgoing calls, incoming calls are time-limited and
easily controlled (prolongation, end).
If the operator calls back and wants to get connected to the audio unit from which the
preceding call was made, enter 0 in the voice menu.

Call Sequencing
If another request arises during communication, the calls are queued. Calls have
different priorities – fire call have the highest one. Therefore, the alarm call suspends
any lower-priority call (the checking call, e.g.). Calls with identical priorities are
queued and processed one after another. Having done that, LN recovers the
suspended activity if possible.

na = not applicable
ns = cannot be served
Q = to be queued
S = current activity suspended

Situation
LN Activity
Busy tone after number
dialling end
LN hangs up and dials the next number in the
sequence.
Call or silence
LN waits for a pre-set period of time (see Parameter
913).
Ringing tone
LN waits for a pre-set count of rings (see Parameter
954), then hangs up and dials the next number.
Continuous tone (on a PBX
line, e.g.)
LN hangs up and dials the next number.
DTMF character , or
LN hangs up immediately and dials the next number.
DTMF character
LN confirms receipt (2 beeps), mutes the current voice
message and the call goes on for the maximum pre-set
time (maximum call duration).
These digits are interpreted as control characters
(refer to Subs. 3.6).
Automatic Dialling of Multiple Numbers with
Confirmation
Up to 6 telephone numbers including repetitions can be stored for dispatching office
calling. LN then tries to call all the numbers stored. To confirm successful calls, LN
uses tone dialling (DTMF). Having received a call manually, the dispatching office
officer has to press the button on his or her telephone (tone dialling). If the
called line is busy, or is unanswered within a timeout, or the call is not confirmed, LN
dials the numbers in the sequence until it exhausts all pre-set attempts. The
procedure is the same for checking calls or failure reports but a separate group of six
numbers can be used.
Evaluation of Situations during Automatic Audible Dialling with
Confirmation
Note
The PSTN connection quality is not so high as to identify the above
mentioned situations reliably in all cases. Moreover, excessive noise in the
lift cabin may decelerate automatic dialling (due to inability to recognise
the busy tone, e.g.). In general, DTMF is the most reliable type of
signalling and so is used for confirming receipts. Thus, the connection is
established (yet for a shorter time than usual) even in extreme cases, e.g.
when LN cannot identify the DTMF.

These digits are interpreted as the beginning of a
switch control password.
Automatic Redialling of Multiple Numbers without
Confirmation
This mode is useful where no trained personnel for automatic dialling with
confirmation are available. The called party does not have to press any button. The
two modes share a set of numbers, have an identical count of cycles, respond to the
busy tone in the same way, etc.
The only difference is that the no-confirmation mode waits for the ringing tone and
recognises that the called party has answered when the ringing tone terminates before
the timeout end and that the connection has been made successfully.
In this mode, LN does not repeat the “Wait please” message (or any user-recorded
message) after the dialling end, because it would be impossible to recognise ringing
reliably. The message is played back once shortly after the called party answers. The
message speaker cannot be controlled using buttons to .
Evaluation of Situations during Automatic Audible Dialling
without Confirmation
Warning
Make sure in this mode that no VoiceMail box, FAX machine or any other
equipment are assigned to the numbers to be dialled that might answer
the call before the pre-programmed timeout end and thus terminate
automatic dialling.

parameters 946 and 947.
Use of Switches
Every machine room audio unit is equipped with a switch, which enables to block the
lift function in case LN fails to call for help in the event of:
telephone line failure;
power outage and back-up battery discharge.

Battery Maintenance
5.1
5.1 Battery Maintenance
First put the accumulators in operation as described in the Description and Installation
section (PSTN Central Unit, Before You Start). Also, pay attention to them whenever
the operation is interrupted and during replacement. The basic rules are as follows:
Warning
Never leave the batteries discharged for unnecessarily long periods.
If the battery is fully discharged, please recharge it as soon as possible.
Interruption of Operation
The interruption of service means that LN is without a power supply for a rather long
time. The battery is not being charged and can be damaged. This situation may occur
in the following cases:
In a building under construction or in an unused building where the power
supply may be turned off for weeks or even months;
While replacing the CU;
At the end of a testing, exhibition or similar event.
In such cases, open the CU and remove the battery or disconnect it placing the
transport tape between the battery contact and the holder contact.
List of Battery Endangering Situations
1. CU installation in an unfinished new building.
Remember that the power may be switched off for weeks or even months in a
building that has not been put in operation yet. If necessary, install the
communicator here, check its function and remember to protect the batteries
against depletion – remove them or disconnect using the transport tape. If the
risk is not so high, just disconnect the green connector. Both the steps,
however, may only be performed when the elevators are out of operation.
2. Excessively long storage periods.
Make sure that your storage obeys the FIFO (first in first out) principle. If the
end of the six-month storage period is approaching, you may recharge the
batteries in the product (see above), replace the transport tape and continue
storing the product.
3. Dismantling CU.
If, for whatever reason (warranty claim, transport to service site in order to
upgrade, etc.), you dismantle the CU, remember that the CU is still “working”.
This way it may be stored without recharging for no longer than 1 week, or,
after having been fully recharged, no longer than 1 month. If there is a risk of
exceeding this period, remove the batteries or disconnect them using the
transport tape.
4. Testing, exhibitions and presentations.
If you operate the communicator for example at an exhibition, remember that
the entire set may be disconnected from the power supply. In such case the
84

batteries will discharge. Do not forget to recharge them as soon as possible, or
– preferably – disconnect the green connector if you do not need to have the
system on.
Battery Pack Replacement
Battery Pack Service Life
The warranty period does not apply to common wear and tear, i.e. the battery
depreciation. If, however, the product is used normally, the battery service
life is substantially higher than the warranty period.
LN monitors the battery pack status and indicates the need of replacement
upon a certain capacity drop.
Where the dispatching office is equipped with the 2N
this information is automatically transmitted as an error message.
For replacement, four new Ni-MH accumulators of size AA and minimum capacity of
2000 mAh are needed. Make sure that accumulators of the same type and production
series are used. You are recommended to use the batteries delivered in groups of four
by the manufacturer. The recommended type is SANYO Eneloop 2000.
