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.

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

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

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.

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
