PREPOJ) – simultaneous connection of all units with
operator/ connection machine room – shaft – cabin only
 Changeable back up Accumulator (ACU)
 User friendly installation as same as settings
(for start just saving 1 phone number on the SIM card)
 After activation (button push) progressively call up 7
numbers (MASTER1-7) saved on the SIM card.
Other numbers are restricted to call.
 Automatic verification call once for 1-9 days to TEST
number(s) (TEST1-7) saved on the SIM card
 Adjustable emergency call blocking (delay/ prolong of
blocking) - if the call button is held for more than 30s,

2
the call is made regardless of the blocking (EN 81-
28:2018)
 Indication of establishing as same as running call.
Indication of other device status by switches for optical
signalization and acoustically (voice messages) –
possibility record own messages
 Relay mode for lift blocking during lift failure or GLWV
issue (GSM network logging, correct ACU voltage, not
blocking emergency call button)
 Call back only from numbers saved on SIM card (other
calls are blocked)
 Automatic call termination after 5 minutes
 Individual acoustic test (speaker/MIC check, ReMic
connection)
 „Emergency“ status with saving time and date of call,
cancel locally (technician) or remotely (SMS) according
to the standard EN 81-28:2018
 During the "Emergency" state call blocking is cancelled,
incoming calls can be made from any number. Outgoing
calls are not blocked.
 Notification SMS with low voltage info (adjustable
value), Announcement SMS with correct voltage info
(return over setup value), Notification SMS with info
about low voltage of backup ACU
 Report of service lift visits includes date of last visit
 Exact date and time from GSM network
 Resending of GSM operator SMS to preprogramed
number (TEST8)
 Operation with or without PIN code – automatically
generation of random PIN for SIM card (protection
against abuse)
 Command SMS mode for remote management (SMS is
possible send just from TESTx numbers):
o Setting of all parameters
o Relays contacts control

3
o Device status info (voltage level includes ACU,
time, „Emergency“, operator, temperature,
blocking status, input status, relay status,
acoustic test result…)
o Cancel status „Emergency“
o MASTER and TEST numbers exchange
o GSM network status
o SMS with AT commands for GSM module
 Sending of adjustable SMS when input status is
changed – individual SMS for both input status
 SMS when the button is locked for more than 60
seconds.
 7 modes of relay closing
 automatic 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 GLWV) to number of SIM card
inserted into GLWV. 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 „Wait please to connection“ and the unit
progressively dials phone numbers saved under names
MASTER1 to MASTER7 on inserted SIM card. Before dialling
each number is activated voice message „Wait please to
connection”. Once the connection to the station has been
established, other numbers are no longer counted. Ports I1
and I2 (yellow and green light) are switched on / off depending
on the type of ReMic used (and the standard - see table). The
"Emergency Lift Communicator" message is activated (the lift
location can be reached). The system returns to standby by
ending the call with the station. The port (s) (I1, I2) on the
ReMic (see the table) is disconnected and the "call is
terminated" message is activated.

Example 1 (indication according to EN 81-28: 2018):
Setting
Numbers MASTER1 and MASTER2,
Activation time 3 s
Waiting for dialling next number 20 s
Emergency alarm mode (ECALL) set (= 1)
After button press for time longer than 3 sec is closed port I1, it
is play message „Wait, please, to connection“, it is dialling
number saved under MASTER1. Nobody picks up. The 20s
after number dial is calling ended. Again is activated message
„Wait, please, to connection“ and is dialling number saved
under MASTER2. Call is picked up. Port I1 remains closed
and I2 port is closed also. It is activated message „Emergency
communicator of lift“. Call is running. Called party hang up the
call. Ports I2 are switch off (function “EMERGENCY mode” is
on). It is activated message „call is terminated“. After the
situation is resolved (rescuing the person from the elevator),
the lift technician terminates the EMERGENCE (ALARM)
status (button or SMS) and also I1 is open.
Example 2:
Setting
Numbers MASTER1, MASTER2, MASTER5
Activation time 3 s
Waiting for dialling next number 20 s
Emergency alarm mode (ECALL) set (= 1)
After button press for time longer than 3 sec is closed port I1, it
is play message „Wait, please, to connection“, it is dialling
number saved under MASTER1. Nobody picks up. The 20s
after number dial is calling ended. Again is activated message
„Wait, please, to connection“ and is dialling number saved
under MASTER2. Nobody picks up. After 20 sec is calling
ended. The unit identify that there is not MASTER3 number

6
saved – next number in order. It is activated message
„Connection failed. Try again later please.“ Port I1 remains
closed (EMERGENCY (ALARM) status is activated). Number
MASTER5 (numbers saved after interrupted serie) 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.“. But if the button is
pressed for more than 30 seconds, the lockout is cancelled
and the emergency call is activated (EN 81-28: 2018)
Example1
Blocking is connected to door contact. The door are opened-
port is short circuited
Setting:
Activation time of port short circuit 3s
Blocking surveillance 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.
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

7
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.
Example3
Blocking is connected to elevator fault status output, elevator
fault - port shorted.
Setting:
Activation time of port short circuit 1s
Blocking surveillance after port is deactivated 1s
An emergency call is only possible in the event of an indicated
lift fault
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. In the "Emergency" state, the
communicator receives calls from any phone number.
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 behaviour is
similar like during emergency call just other numbers are
called (not MASTER but TEST) and blocking port is ignored.

8
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
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 (GLWV – cables – ReMic speaker –
ReMic microphone – cables GLWV). During test is activated
message „Sound test – one, two, three, four – end.“. The
GLWV 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
surrounding 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 GLWV
GSM operator
GLWV 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 „Service 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.

If the connection fails to connect, the I1 and I2 ports alternately
switch on / off at one-second rhythm. Alternate blinking takes
place until another outgoing call (emergency or test) can be
established - EN 81-28: 2018.
Status information (SMS)
Status information’s GLWV 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 preprogramed level for longer time tan 1 minute.
The SMS 'Power OK' is sends to TEST8 number when
power supply increase over preprogramed 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 preprogramed level (3.3V). The GLW
V than works correctly approximately 1 hour. When
power supply is reactivated after this time the unit
behaviour 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 service 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

10
blocked button) for time longer than 1 minute, 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
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 programme for GLWVset (via later).
Emergency alarm mode
At this setting is activated „emergency“ (Alarm) mode during
emergency call (EN 81-28:2018). 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 (technician locally after fixing of
emergency call problem ) or remotely by SMS 'RESET
ECALL'. During this state the pushbutton blocking via IN2 is
cancelled, also incoming calls only from the allowed numbers
(the incoming call can be from any number).
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

11
call. Relay is closed when unit is registered 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 preprogramed time.(
adjustable).
 „Button“ mode, when relay close after emergency call
button is pressed and stays closed for preprogramed
time ( adjustable).
 „Service OK“ mode. In this mode relay is closed for
preprogramed 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
„Service OK“)
Information of relay status is in STATUS/TEST SMS.
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 module.
 Every GSM LiftWatch Voice has his own PIN (of course
it is 4 digit number)

12
 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 module. 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 (height 22mm)
Installation:
 Fix the acoustic unit (ReMicA/L) 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!

 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.
