Welcome
The Link Lift Watch is designed for emergency call from lift to first aid ( service
department, police, etc…
The NLLW is certained for 1 lift cabin. It is connectable to analog PSTN
line or analog extension of PABX. The NLLW is powered from telephone line –
the features reminds hands free phone. It is completely independent on lift
power supply.The signalization as same as status detection only requires
connection of external power supply. All inputs even outputs are galvanically
isolated from telephone line. The button as same as control („third“) wire only
is connected with telephone line.
The NLLW has adjustable parametres saved in internal memory. The
parametres might be programmed either by phone via tone (DTMF) dial or by
computer PC via configuration software. For connection the NLLW to PC you
have to use special cabel.
After button pressing the NLLW enables to make phone call up 6 numbers
max 16 digits in tone or pulse dial. It is possible also dial
“* ”, “ # ”, Pauze and Flash in tone dial. The button activation might be
blocked by input BLOCK. As follow NLLW enables to make a call in case of
change the status at input INPUT (failure). The NLLW also provides automatic
phone call from systém time clock to confirm its functionality.
At all numbers is possible to use mode with or without confirmation.
After confirmation of phone call by called party the NLLW reply by its seriál
number and current call is taken as accepted. It means that NLLW not dial any
other number saved in memory.
The next feature is remote control of relay in connection with NLLW by 2
digit code. The switching contact of relay is isolated from the outstanding
components. It is very useful feature for example : LIFT RESET .

independent of polarity and you select 3 mode. First mode is current loop
powered from 12-24V, second mode is using only if you haven't power
supply, then you use power for current loop from telephone line –CAUTION
!! It is not galvanically isolated. Third mode is external power - for example:
button connection parallely to sirene (powered 12-24V)
The possibility of activation via third wire from „ transffer tool“ for
communication with machine room
BLOCK - security against disusing of alarm buttons (activation during
failure 5-24V).
INPUT - it includes universal input which you can use for failure
announcement ( doors, power supply, etc..) You can programm special
phone number .
All inputs as same as outputs are galvanicaly isolated –not depends on
polarity. ( except button and third wire for machine room).
Acoustic as same as optical signalling of NLLW status
The possibility to programm 6 numbers ( 16 digits –includes
*,#,Pause,Flash) with note if you want use confirmation or not .The numbers
are progressivelly dial.
Regular automatic control of system functionality ( automatic calling to
preprogrammed numbers in set time period from 1 to 10 days)
The possibility programm code for remote activation or unactivation of LLW

Possibility connect 1-3 microphones (attention on polarity of electret
microphone) and posibility connect 1-3 speakers

Differences between version A and version B
version B makes it possible connect only 1 microphone and 1 speaker
version B hasn't relay (remote switch) and INPUT (failure announcement)
version B hasn't adjustable level of DTMF and has fix -10dBm
1.2 Terminology
It is explain here the meaning of used words in manual.
Communicator LLW - it is final product designed for communication from
lift cabin to service center.
Emergency call - it is person calling while lift failure or other
emergency situation happened. It is activates by
button pushing. The call is being between lift cabin
and service center.
Service calling - it is calling regularly repeated. (for example every 3
days). It is automatic proving of NLLW functionality. )
Failure calling - it is calling caused by status change on input
INPUT
Machine room call - it is calling between lift cabin and machine room, )
Incoming call - it is calling coming from outside into NLLW unit.
The NLLW pick up (you can programm
parametres)
Dial - it is kind of dial on telephone line –dial (DTMF) dial
(dial even acknowledgement * and # , use loop
interuption = Flash) or pulse –(dial only numeral)
Telephone line - PSTN line (public line) (line coming directly from
Telecommunication carrier) or extension line
(coming from PBX)
confirmation - dial of combination star *and numerals. After
dialling of those characters the call is authorised and
lift communicator reply by its unique serial number.
(5 digits)
serial number - each lift communicator NLLW has unique seriál
number since 00001 to 65535. This number is
sending via DTMF every time when NLLW receives
confirmation character
call connection - this status is indicated via lighting of green check –
light and might be caused either by call confirmation
( dial confirmation character) or when is not present
ringing tone for longer time period.

1.3 Wiring contacts
1.3.1 Description of basic module
The NLLW is compact solution of communicator, it means that contains
loudspeaker, microphone, screw terminal and connector for PC connection
(configuration). At picture 1 is drawing of NLLW basic board (version A).
Functionality of connection is explain in follow chapters. On the basic board are
3 setting elements ( trimmers) :
MIC –microphone volume setting
VOL –loudspeaker volume setting
TRH –setting of balance between micro and speaker
Note: Please take in mind during TRH setting that incoming direction ( speaker)
and outgoing direction ( microphone) are influence each other.
We recommend to dont set high volume in the begining of micro or speaker
and via TRH set both direction to be both in good volume quality.
Picture 1: NLLW basic board
For explanation: when signal into speaker approach certain level then
decreases micro volume to enter signal into speaker. At the other hand signal
from microphone decreases volume of speaker. By TRH trimmer you are
setting prefferention of microphone or speaker.
Here you can see that when is set high volume of microphone (MIC)
as same as speaker (VOL) then signals influence each other. The result might
be that call is interrupted or one direction is silent.

The loudspeaker as same as microphone are connected by wires as
you can see on picture 1. Caution on polarity of microphone because is
powered (+ -).
Version A contain three connectors for connect microphone a three
conectors for connect speaker. Microphones is possible conect to the
conectors MIC1..MIC3 it is paralel inputs with same features. Conectors for
speakers has diferent features, left connector SPK is output from HandsFree
and powered from line (only one for Version B), connectors SPK1..SPK2 is
output from 1W amplifier powered from 12-24V connection (only version A).
The jumper marked SERVICE is available for automatic enter to
programming mode when password is forgotten. When jumper is ON And you
make incoming call on NLLW then after picking up you are directly in
programming mode. In programming mode you can change all parametres
includes new password as well.
Connection of Button (emergency call) and connection of Input (Error
or Technical call) is wiring as current loop and by jumper is possible choice
from the current loop is powered. Attention - button is galvanic connect with
source power of current loop and isolated from line by optocoupler. In case
powered current loop from telephone line is button galvanic connect with
telephone line.
Two jumpers behind connector for connection LEDs determine if they
will be connection indication LEDs (jumers they are open) or indication bulbs or
LEDs with resistor (jumers they are short). These jumpers just short serial
resistors. At using power supply 12V is current LED c. 10mA, at short-circuited
jumpers be allowed max. current 0,5A.
The black connector on oposite side from screw terminal is designed
for PC connection by special cabel KAB. The cabel is galvanicaly isolated
convertor of RS 232 interface (PC port COM1, COM2…) and NLLW interface.
Galvanical isolation is neccessary because PC might be grounded and
telephone line MUST NOT be grounded! When your PC is not equiped by RS
232 port but only USB then you can use convertor USB-RS232 for its is in your
PC creates virtual seriál port (for example COM6) and this you will select in
configuration software LiftSet for communication to NLLW. Is posible too use
USB cable - we recommended.

1.3.2 Setting voice communication
Position trimmers are presetting from manufacture and in majority case
agree with, therefore changes setting altering only in necessary case.
Trimmer "MIC" be instrumental to setting loudness of microphone,
trimmer "SPK" be instrumental to setting loudness loudspeaker. In this version
is big reserve in gain, therefore isn't recommended adjust more than on half,
typical is in 1/3 from minimum gain. Trimmer "TRH" be instrumental to setting
levels activation of microphone, it means, so as doorphone "non whoop" owing
to acoustic loop so selection, which direction has priority, whether from
microphone, or into loudspeaker. Level from which volume with "switch on"
direction from microphone doorphone setting trimmer „TRH". This setting
interact level surrounding noise and setting gain of microphone „MIC".
Progress of setting: trimmer MIC and SPK setting in 1/4 from minimum
loudness (minimum is sense turning left), trimmer TRH setting in central
position. At conversation
connection stilly talk and trimmer
TRH turning from central value
direction to the left so, till you will
on the side phone (in building)
hear. Gain of loudspeaker, in
some case of microphone set-up
according to needs.
Picture 2: Typical range and sense of rotation trimmers
1.3.3 DTMF level setting
Level of DTMF dial it is possible adjust in three
levels, base level is -10dBm, here it is possible restrict
to -14dBm and or heighten on -6dBm. Setting is makes
by DIP switch according to pictures.

1.3.4 Telephone line connection (LINE a b)
The basic condition for NLLW operation is telephone line connection.
Telephone line is 2 wires which you connect to screw terminal up picture 3.
Picture 3: Telephone line connection
Telephone line interface has following typical parametres. The voltage in
Hang up status (disconnect loop) 20-60V = (during connection not depends on
polarity), when NLLW pick up (active status) on telephone line is cca 7-12V,
depends on line current which is in range 20-60mA. Further telephone line
parametres are signalling, ringing (incoming call) is define by AC voltage from
50-90V and frequency 20 –60Hz. To the signalling belongs even tones, have
frequency 425Hz +/- 20Hz and level -10dBm (cca 0,22V) and difference lis
cadency. The NLLW reacts on those tones.
