automatical limiter of MIC amplification
Setting/programming
There are 3 possibilities:
1) when you use SIM card from previous model GSM Lift
Watch then just insert this SIM into new model GSM LW
Voice. All settings except SMS will be automatically
saved into new GSM LW Voice.
2) Insert SIM card into ordinary mobile phone and save on
the SIM desired number for emergency call under name
MASTER1, eventually TEST1 (more details capture
programming).
3) Start the unit (via. capture Start the unit). Send SMS
„INIT TEST1 xxxxxxxx“ (xxxxxxx is number from which
you will be programm GLW) to number of SIM card
inserted into GLW. Wait for answer („OK“). From
number TEST1 send SMS „WRITE MASTER1
yyyyyyyy“ (yyyyyyyy is number onto which GLW will be
call when emergency button is pressed.).
Detail settings:
1) Setting by GLWVset program
2) By SMS
Detail settings will be explained later in manual in appropriate
capture.

Emergency call from lift cabin
By button press you activate the device (adjustable button
pressing time for activation). It is close port I1 on ReMic (for
lighting up yellow indication light – activation/call establish),
You hear message „number dialing, wait“ and the unit
progresivelly dials phone numbers saved under names
MASTER1 to MASTER7 on inserted SIM card. Before dialing
each number is activated voice message „number dialing, wait
When call is picked up the other numbers are not dialed. Port
I1 on ReMic is switch off. Instead of I1 are closed contacts of
port I2 (for lighting up green light – call picked up). It is
activated message „emergency communicator of lift“ (could be
also add place where is lift installed). The unit returns into
stand by mode when call is hanged up. Port I2 is switch off
and is activated message „call ended“.
Example 1:
Setup
Numbers MASTER1 and MASTER2,
Activation time 3 s
Waiting for dialing next number 20 s
After button press for time longer than 3 sec is closed port I1, it
is play message „number dialing, wait “, it is dialing number
saved under MASTER1. Nobody picks up. The 20s after
number dial is calling ended. Again is activated message
„number dialing, wait “ and is dialing number saved under
MASTER2. Call is picked up. Port I1 is switch off and port I2 is
closed. It is activated message „emergency communicator of
lift“. Call is running. Called party hang up the call. Port I2 is
switch off. It is activated message „call is ended“.
Example 2:
Setup
Numbers MASTER1, MASTER2, MASTER5
Activation time 3 s

5
Waiting for dialing next number 20 s
After button press for time longer than 3 sec is closed port I1, it
is play message „number dialing, wait “, it is dialing number
saved under MASTER1. Nobody picks up. The 20s after
number dial is calling ended. Again is activated message
„number dialing, wait “ and is dialing number saved under
MASTER2. Nobody picks up. After 20sec is calling ended. The
unit identify that there is not MASTER3 number saved – next
number in order. It is activated message „connection failed.
Try again later please.“ Port I1 is switch off. Number
MASTER5 (numbers saved after interrupted line) are used as
numbers which you can make incoming call into unit.
Blocking of emergency call
Emergency call activation might be blocked by short circuit of
blocking input IN2. It is adjustable how long must be port
closed for blocking activation as same as time for which is
blocking still active even port is deactivated ( off). In case of
button press during blocking ( button press for time necessary
to activate emergency call) is activated message „Emergency
call is blocked. Try again later please.“.
Example1
Blocking is connected to door contact. The door are opened-
port is short circuited
Setting:
Activation time of port short circuit 3s
Blocking survilance after port is deactivated 65s (time of
longest lift run)
Lift doors are closing, lift starts running, call is blocked. After
button is pressed the message „Emergency call is blocked.
Try again later please.“ Is activated.

6
Example2
Blocking is connected to door contact. The door are opened-
port is short circuited
Setting:
Activation time of port short circuit 3s
Blocking survilance after port is deactivated 65s (time of
longest lift run
Lift doors are closing, lift starts running, call is blocked . The lift
stops, the doors are not opening. Lift service try open doors
manually, press different buttons. Meantime run out blocking
time. The service person press emergency call button –
continue via examples emergency call.
Caution: If the button is pressed for emergency
communication for longer than 30 seconds, the call is made
and when blocking
Back calling
The unit might be activated also by calling to his phone
number. Connected will be numbers saved on SIM card only.
Other numbers are ignored. Due this is possible even without
people in lift cabin assistance make again connection and
control situation in lift cabin. If the connection is established, is
replayed message „emergency communicator of lift“ for
possible identification.
Testing (control) calling
When are saved on the SIM card numbers under names
TEST1 to TEST7 then is generated automatic call into those
numbers every 3 days ( adjustable). The unit behavior is
similar like during emergency call just other numbers are
called (not MASTER but TEST) and blocking port is ignored.
There is also activated different voice message during
activation and call picked up - „Attention it is test of
connection“. When call is hanged up then is activated standard

7
message „Call is ended“. Phone numbers might be the same
in both sets ( MASTER and TEST).
In the same time might be beside or instead testing call tested
local acoustic connection (GLW – cables – ReMic speaker –
ReMic microphone – cables GLW). During test is activated
message „Sound test – one,two,three , four – end.“. The GLW
V measures change of signal level identified by MIC between
stand by mode and sound level during message playing. The
testing will not be correctly evaluated when surronding noise is
too high – any or very small change signal level.
The Test can discover not connected ReMic or short circuited
MIC.
In the same time might be send SMS TEST including info:
Firmware version
Back up ACU voltage
Power supply voltage
Setup time and date in GLW V
GSM operator
GLW V temperature
Number of service visits with date of last one (1)
Input status IN1
Blocking status (input IN2)
Relay status
Date and time of last emergency call (2)
Result of acoustic test (3)
1) When „Servis OK“ mode was setup
2) When was setup „Emergency“ mode it is shown, date
and time last mode activation. When mode is
deactivated (remotely or locally) it is signalized by „- -„
3) When is setup Acoustic test as same as sending SMS
TEST then acoustic test is firstly made to be mentioned
current status in SMS TEST.

Status information (SMS)
Status informations GLW V sending by different SMS:
TEST/STATUS: SMS via previous capture. Except test
could be activated also by SMS „READ STATUS“ (more
about in capture about SMS). When is setup Acoustic
test then is performed always before SMS sending.
Power supply information: SMS 'Power LOW' is
sends to TEST8 number when power supply decrease
under preprogrammed level for longer time tan 1 minute.
The SMS 'Power OK' is sends to TEST8 number when
power supply increase over preprogrammed level for
longer time than 1 minute.
Discharged back up ACU information: SMS „Low
Voltage“ is sends to TEST8 number when Acu voltage
decrease under preprogrammed level (3.3V). The GLW
V than works correctly aproximatelly 1 hour. When
power supply is reactivated after this time the unit
behavior is like when you start it. ( switch ON) ( SMS
'Power OK' is not sends).
Input change IN1 information: SMS with info about
input change from open to closed (‚PORT OPEN‘) is
sends to PORTOPEN number. The SMS with info
about input change from closed to open (‚PORT
CLOSE‘) is sends to PORTCLOSE number . When
mode „Emergency alarm“ is setup then during IN1 port
closing (etc. Reset emergency status) is sending to
PORTCLOSE number SMS in format 'Reset last
Emergency Call'. When servis is setup then during port
closing is sends SMS in format 'SERVICE'
Button blocking: when is detected short circuit at
button of emergency call activation (for example
blocked button) for time longer than 10 minutes then is
sending SMS ‚ ‚Button blocked‘ to TEST8 number.
GSM operator information: when is GSM operator
number saved on the SIM card under name its part

9
includes word „oper“ then all SMS received from this
number will be forwarded automatically to TEST 8
number.
Contents of all SMS (text of all SMS) might be edited up desire
by PC programm for GLWVset (via later).
Emergency alarm mode
At this setting is activated „emergency“ mode during
emergency call. The date and time of this status is recorded
for report in SMS STATUS. Up settings might be during
„emergency“ mode closed relay – status indication,
activation/blocking of further activities in the lift.
The status „emergency“ is possible cancel up settings either
by short circuit on port IN1 (technican locally after fixing of
emergency call problem ) or remotely by SMS 'RESET'.
Example: Up expression of some directives EN 81-28 / EN 81-
70 has to be blocked next emergency call until fixing of
problem at the place of lift installation.
Setup
Emergency alarm mode ( ECALL),
Relay mode: Emergency alarm mode
Over relay connected blocking INP2 to ground
To IN1port in machine room connected button.
After creating of emergency connection is activated
„emergency“ mode. Relay is closed and by its contact is
blocked next emergency call. Incoming calls from permitted
numbers is allowed. Technican after arrival and problem fixing
will push button on port IN1 (the pressed button is hold until
yellow LED GSM will not start flashing quickly.) . By this cancel
„emergency“ mode. It is sends SMS 'Reset last Emergency
Call' and relay open contact for blocking of emergency call
(Green LED REL light off). It is „stand by mode“ again.

10
Relay
The Relays might be programmed into 7 different modes:
Close/open is control by SMS (for example. „SET REL1
ON“)
Close/open is control by „emergency“ status (via
previous capture)
„Camera“ mode when relay close after call is picking up
and open when call is hanged up
„Running“ mode for eventual lift blocking: Close/open is
control by unit status – its functionality for emergency
call. Relay is closed when unit is registrated to GSM
network ,it is correct voltage on backup ACU, (internal
unit voltage) and it is not blocked (emergency call
button is permanently pressed) . The contact connect to
appropriate input of lift control unit. The lift control unit
must provide to go to nearest station after open/close
of contact (switching relay) and open the door and stay
out of order.
„Lighting“ mode when relay close when call is picked
up (the same like camera mode“). But when call is
hanged up the relay stays close for preprogrammed
time.( adjustable).
„Button“ mode, when relay close after emergency call
button is pressed and stays closed for preprogrammed
time ( adjustable).
„Servis OK“ mode. In this mode relay is closed for
preprogrammed time after short circuit on port IN1.
Simultaneously is send SMS 'SERVICE' to number
saved under PORTCLOSE and into phone number
saved under name SERVICES is saved current date
with number of all short circuit on IN1 (message „Servis
OK“)
Information of relay status is in STATUS/TEST SMS.

11
SIM PIN
When you desire to operate the unit with SIM card without PIN
then before inserting SIM card into unit switch off the PIN.
(in any mobile phone)
When you desire to operate the unit with SIM card with PIN
you have to setup PIN at any mobile phone to 0000.
GSM LiftWatch Voice will change this PIN (0000) to other PIN
when you insert the SIM card into unit. The new PIN is
calculated from GSM modul.
Every GSM LiftWatch Voice has his own PIN (of course
it is 4 digit number)
When you will want use this SIM at any other device
you have to know PIN2 of this SIM card – because you
don't know the PIN you will need the PIN2 to setup new
PIN (possibly again 0000 for using in other GLWV) –
work with PIN/PIN2 has no influence to saved data and
settings. There are stayed saved on the SIM card.
CAUTION! When you insert SIM card with different
PIN than 0000 the unit will not work!!! Exception is
inserting SIM card with PIN corresponding to unique
GSM modul . So when you switch off GLWV and out
the SIM and again insert it back to the same unit then
all will work correctly even without PIN change.

Installation:
Fix the acoustic unit (ReMic) behind table panel in the lift
cabin. To approach good voice quality we recommend
place the REMIC unit in level of human head. At front of
MIC must be hole in table button panel otherwise there
will be bad voice quality from lift cabin!
speaker and MIC are
installed toward to lift
cabin
Fixing of REMIC at
back side of lift cabin
( button panel)
(for example by
screws)

17
Fix the GSM part of unit either on lift cabin or in machine
room. You have to select right place regards to GSM signal
strength.Lift cabin installation is easier (it is not necessary
cable from lift cabin to machine room and due this is avoid
of interference). However you have to provide good signal
strength for all lift shaft ! Keep in mind enough manipulation
space for SIM card.

18
Screw up antenna cable connector. The antenna position
must not be in space surronding by metal (metal shafts
etc..) It caused reduction of GSM signal. When you connect
magnetic antenna please put it to some bigger iron subject.
which enables to create bigger GSM signal power. It is also
important to place antenna out of basic unit to not
interference the voice channel by GSM radiation ( you
know it from radio in car)
Up drawing mentioned above connect ReMic modul to
basic unit. To the ReMic modul connect indication And
activation button. Do not connect power supply. At the
basic unit do not connect inputs (port) yet.
Operation start:
When you programm parameters directly to SIM by savings
numbers and names please insert SIM into mobile phone
and programm it.
Switch off PIN on the SIM card or setup PIN 0000 (via
capture SIM PIN). Programmed SIM (via previous item) or
not programmed SIM insert to the unit (via picture .) and
by push lock it up.
When you have installed ACU let its switch in bottom
position (switch off).
Connect power supply

19
Blue LED lights up (PWR) as same as RED LED on
speaker modul (ReMic).
Until cca 5 seconds you hear beeps from REMIC speaker
Until cca 25 seconds will start flashing yellow LED (GSM)
Until cca cca 1 minute (up GSM network status) you hear
message „Unit is in stand by mode“. The yellow LED (GSM)
will start flashing (1 to 5 flash)up GSM network signal
strength. When is setup relay mode „running“ its closed
(light up green LED REL).
When you programm the unit by computer please connect
USB cable and follow instructions in appropriate capture.
When you programm the unit by SMS and there is not
saved any TESTx (x is number 1-8)number on the SIM
card please send SMS „INIT TEST1 xxxxxxxx“ (xxxxxxx is
number which from you will programm GLW V) to number
of SIM card inserted in GLW V. Wait for answer („OK“).
When you programm the unit by SMS and there is already
saved TESTx (x is number 1-8)number please use this
TESTx number for sending SMS. From other numbers
SMS are not accepted. Send SMS „WRITE MASTER1
yyyyyyyy“ (yyyyyyyy is number which will be called when
button is pressed). Eventually further setting SMS (via table
in appropriate capture).
Push emergency call button (calls may not be blocked – via.
Input for emergency call blocking): During button press
lights red LED „alarm“ (ARM) on the GLWV and light off red
LED on ReMic. During button push for preprogrammed
time necessary for emergency call activation you hear tone
of pressed button. It lights up yellow LED „activation“ (ACT),
ON ReMic I1 port will be closed and „Dial wait“ message is
played. It is dial number saved under MASTER1. In
speaker you hear signaling from GSM network (searching
called party, ringing tone etc..) When call is picked up by
called party then is made connection to lift cabin. Port I1
contacts are opened and I2 port contacts are closed. Lights
