1.3. GENERAL DESCRIPTION
Four zone control and monitoring device GsmAlarm-420 can be used for protection of cars, boats,
houses, apartments, garages, and cottages. In the case of a breach of the protected zone and
depending on the programmed system operation algorithm, GsmAlarm-420 switches on the siren ,
calls and sends SMS messages to five users. After answering the call, a user can remotely control the
system by means of his phone keypad (DTMF tones) (e.g., stop a car engine), can listen to what is
going on in the room, request an SMS with detailed information on the state and the number of
activations of each controlled zone.
GsmAlarm-420 has 2 (3, if a siren is not used) programmable outputs, intended for remote control of
different devices. A user can turn on/off heating, ventilation or lighting systems, etc., via a mobile
phone just by typing a relevant code or sending SMS to the control device.
For user’s convenience, the system can indicate entrance/exit with an audio signal, if the miniature
sound signalization element is connected to system.
A user will receive an SMS message, if GSM connection was lost for over 30 seconds. The message
is sent only when the protection mode is turned on.
The device suites perfectly for remote control of automated gates, fences and electromagnetic door
locks.In order to open a gate, a user calls the number of GsmAlarm-420. Then GsmAlarm-420
verifies that the caller’s number is in the list of the programmed user numbers and in case of positive
confirmation switches on the gate control device and automatically terminates the call. Up to 250
users can control a gate.
The system answers only to calls from the pre-programmed numbers. If the system receives a call
from an alien number, the call is immediately terminated and an SMS is sent the user, indicating the
caller's phone number. SMS messages are also sent to users in case of loss and restoration of power.
Operation of the alarm can be check by a short call to the GsmAlarm-420 number. If GsmAlarm-420
is operative, the caller will get a short confirmation call.
All GsmAlarm-420 parameters are programmable remotely by means of SMS messages with
respective content and the password.

2.1. INPUTS Z1-Z5
Inputs Z1-Z5 are used to connect sensors of protected zones. The
inputs can operate in a “loaded input” mode or in a “zero-one”
mode (see Ch. 5.3.1.2). The “loaded input” mode is
recommended to be used for protection of premises. In this case
all the inputs have to be loaded with 2,2kΩresistors. The system
becomes triggered both when the monitored input circuit is
broken as well as when it is short-circuited.
In the second case the system is triggered after breaking or short-
circuiting of the monitored input circuit (depending on the
programmed "active" level).
Equivalent diagram of input
Input Z5 is used to arm/disarm the system. System can be armed by applying active level to Z5. After
the delay time passes, the system starts checking the monitored inputs; in the case of alarm it
activates the siren, calls and sends SMSs. After Z5 level is changed, the system is disarmed and
responds to no zone changes (except when the monitored zone is operative 24 hours per day).

Wiring diagram for premise protection
In armed mode inputs Z1-Z5 must be loaded with 2,2kΩresistors. It is recommended to install
resistors in the most distant point of the line, close to sensor. This will guarantee alarm activation in
case of short circuiting or breaking of sensor circuit. If external LED MODE is not in use, remote
control relay can be connected to contact C1.
LED must be installed withindoors in a prominent place. LED state indicates system operation mode
status, if all protected zones are closed before switching on armed mode.
User can arm/ disarm system with short call from user mobile phone (parameter F should be F51 or
F41, see Ch. 5.3.2.3). Please note, if trying to call the system in alarm state, deactivation is not
possible, therefore it is recommended to use switch ON-OFF designed for activation/ deactivation of
armed mode. The switch can be connected to any zone instead of sensor contacts. Zone, designated
for sensor connection must operate in ON/OFF mode (A33, see Ch. 5.3.1.2). Armed mode is
activated if there is open circuit in switch contacts. Armed mode is deactivated by closing circuit in
switch contacts.
It is recommended to install remote control relays into sockets (e.g., F95913) which can be easily
fixed to metal housing. Operating current of relay coil can not exceed 150mA max. (e.g., F4031-12).
Relays are selected depending on desirable commutative voltage and current.
The LED indicator is optional, but it helps to determine the operating mode of the system and
confirm closure of all protected zones before activation of the protection mode, etc. LED indicator
should be installed in a prominent location inside the premises.
When the system operates the gate control mode, the power supply transformer and the backup
battery are connected according to the wiring diagram of premise protection. The remote control
Relay 1 is connected to the terminals C1 and AUX. The gate control system is connected to the relay

Wiring diagram for vehicle protection
GsmAlarm-420 must be installed inside the vehicle passenger compartment in difficult access area.
Mount the device in place free from penetration of moisture and other corrosion - causing materials,
as far away as possible from heating elements in the passenger compartment and sources of
electromagnetic interference (vehicle computer, conditioner, block of relays). Avoid mounting
system unit directly onto metal parts of vehicle to prevent accumulation of condensate in the system
unit. Mount “GsmAlarm-420” in a way wire connectors are going from the bottom side of the unit.
Avoid placing wires adjacent to moving or hot parts of vehicle. Reserve 6V battery must be accurately
fixed close to “GsmAlarm-420” device. Use plastic fixing belts for fastening. Mount the battery in place
free from penetration of moisture and other corrosion - causing materials, as far away as possible
from heating elements in the passenger compartment. Operating voltage of battery must be 6 V,
system must operate in 6 V mode. Instructions for system reprogramming to vehicle mode described
in chapter 6.2.
Main power to GsmAlarm-420 is supplied (clamp „POWER“) from car battery through 1A standard
5x20 mm fuse, mounted in isolated block PTF/80A. Fuse must be mounted as close as possible to car
battery. Use heat (to +150 °C) and cold (to -60 °C) resistant isolated 0,56 mm² diameter red wire (SPEC
55) to connect „+“ to system power supply. Other system power supply clamp must be connected to car
frame “earth” in nearest most convenient point.
Connect inputs Z1-Z4 to relevant car contactors; input Z5 is used for system arming/disarming. All
outputs in the car mode are working in a zero-one mode; therefore no 2,2kΩresistor loads are
needed.
6V battery supplies power to relay and siren (contact AUX).

4.3. SYSTEM OPERATION SET UP
SIM card is needed for GsmAlarm-420 operation, you may acquire it from any GSM service
provider.
Before inserting SIM card into GsmAlarm-420 SIM card holder set PIN code request off. It can be
performed simply inserting SIM card into any standard mobile phone and following certain phone
user manual instructions.
After system circuit is connected according diagrams showed in chapter 4.1 or 4.2, place SIM card
into GsmAlarm-420 SIM card holder, turn system power on, then wait till indicator SIGNAL will
start to blink periodically and indicator MODE will be constantly alight. In case SIGNAL is
constantly alight, check if SIM card‘s PIN code request is off and GSM antenna is connected. GSM
signal quality can be evaluated according the blinking frequency of SIGNAL indicator. Connection is
very good if it blinks 4 or 5 times with 2 seconds breaks after. SIGNAL indicator blinking fewer
times, indicates weaker connection. Position of GSM antenna might be changed in order to improve
signal quality.
Perform system programming when armed mode is disabled (ON/OFF contacts are closed). Protected
zones must be closed (indicators Z1 – Z4 are off, MODE and LED constantly alight).

PROGRAMMING
_________________________________________________________________________________
GsmAlarm-420 Software ver. 1.05
- 11 -
5. PROGRAMMING
GsmAlarm-420 parameters can be divided into two groups. First group – user phone numbers which
are stored in SIM card memory. User phone numbers can be programmed by using standard mobile
phone of any type (see Ch. 5.2.1) or remotely, sending SMS message with the phone numbers of
users to GsmAlarm-420 (see Ch. 5.2.2).
Second group – parameters, defining system operation algorithms, names of protected zones and
programmable outputs. These parameters are stored in the memory block of GsmAlarm-420 device.
The parameters of the system can be programmed by sending SMS message (see Ch. 5.3). It is
recommended to change the SMS password at the end of programming (see Ch. 5.4)
If GsmAlarm-420 is used for protection, five user numbers can be programmed: ALRNR1, ALRNR2,
ALRNR3, ALRNR4 and ALRNR5. These users can arm/ disarm the system, calls will be directed and
SMS messages will be sent to these users. If only one user exists, he must be programmed under
ALRNR1. GsmAlarm-420 will send SMS messages to this specific user in case of main power
supply loss or if an unknown number calls the system. If armed mode is turned on or off by turning
the switch ON/OFF GsmAlarm-420 dials and SMS messages are also directed to the first user. Other
four user numbers are not obligatory.
In case GsmAlarm-420 is used only for gate control it is not necessary to program ALRNR1-
ALRNR5. Up to 250 user numbers, with the possibility to control the outputs C1, C2, and BELL with
a short call, can be programmed in this case. Any name can be ascribed to user. Output operation
mode has to be M04 or M05 (see Ch. 5.3.2.1).
After programming of user numbers - programmed system parameters, names of inputs and outputs
(see Ch. 5.3).
5.1. USER NUMBER PROGRAMMING WITH STANDARD MOBILE PHONE
Insert SIM card into a standard mobile phone. Enter user name into SIM card number book using
capital letters e.g. ALRNR1 and corresponding phone number. We recommend enter the number with
international code. (E.g. +370....)
If GsmAlarm-420 is used for gate control, number of extra user numbers can be as large as fits into
the SIM card (up to 250). Any name can be ascribed to user.
Important:
It‘s important to note that while programming SIM card memory should be active (not phone
memory!). Otherwise the user number will be recorded in the mobile phone memory used for
programming and the SIM card will remain empty.
After having programmed all user numbers, it is recommended to check whether SMS service centre
number is programmed. Simplest way to check: send any SMS from the phone used for
programming. If it is sent successfully we can be sure that SMS centre number has been programmed
correctly. Otherwise, program SMS centre number following the mobile phone’s user manual. SMS
centre number can be learnt from GSM service provider.
After completion of programming and checking whether SIM card PIN code request is switched off,
take the SIM card off from the mobile phone.

SMS can be sent from any GSM phone, not necessarily the user’s. GsmAlarm-420 confirms
receiving the message with frequent blinking of MODE indicator and sends SMS message including
input parameters Z1- Z5. Received message will look as follows:
AAAAAAAA Z1:M70T20A20 Door, Z2:M70T00A20 Windows,
Z3:M70T00A20 Movement, Z4:M71T00A20 Fire, Z5:M02T00A20 OFF,
AAAAAAAA: password.
Z1: protected zone input number.
M70: parameter defines system response to the violation of protected zone and which users are
informed if certain zone sensors are triggered (see Ch. 5.3.1.1).
T20:delay time after triggering (in seconds), if system is in armed mode. After relevant input is
triggered, the system switches siren on and sends SMS only after expiration of the given
delay time.
Possible values: 0...99 seconds.
A20: input operation mode, parameter A (see Ch. 5.3.1.2).
Door, Windows, Movement, Fire, ON-OFF:input names, which are seen in the SMS after alarm

5.3.2.1. OUTPUT C1, C2 AND BELL OPERATION MODE
Output
mode Explanation of operation
M00 Not in use.
M01 Output controlled by DTMF or SMS instructions.
If zero operation time is programmed (T00), output is activated/deactivated and
remains in the same state after receiving DTMF or SMS instruction.
If not zero operation time is programmed, after receiving DTMF or SMS
instruction, output is activated, it deactivates automatically after expiration of the
programmed time.
M02 LED mode. Output is in operation together with MODE indicator.
M03 Output is activated, when system is armed. Open contact, when system is disarmed.
M04 Control by short call without number recognition function. Output is activated with
a call from any number. If zero operation time is programmed (T00), output state
changes after a call and remains unchanged till the next short call.
If not zero operation time is programmed, after receiving short call instruction
output is activated, it deactivates automatically after expiration of the programmed
period.
M05 Control by short call with number recognition function (gate control mode). This
mode operates analogue to M04, thus it is activated only if short call number
coincides with programmed numbers.
M06 Siren mode. Valid only for output BELL (C3).
M07 Siren mode with audible confirmation. After arming, one short audible sound is
heard. After disarming, two short audible sounds are heard. Valid only for output
BELL (C3).
M08 Miniature siren (buzzer) mode (see Ch. 7.1).
M09 Output is activated if GSM connection is absent for over 30 seconds in the
protection mode. After connection is re-established or protection mode deactivated,
the output is also deactivated. When the connection is normal, the output operates
in the same way as in mode M01.
Outputs are controllable in armed and disarmed modes.
5.3.2.2. PARAMETER E : INFORMING USER ABOUT ARMING AND DISARMING
System response to switching the
armed mode ON
E XY System response to switching
the armed mode OFF
X Y
All functions below are
deactivated. 0 0 All functions below are deactivated.
User is informed by SMS. 1 1 User is informed by SMS.
User is informed with a short call. 2 2 User is informed with a short
call.
- - 4 If during the period of one
minute after disarming by call
no change in the input state is
found, system automatically
returns to “armed” mode.

All functions below are deactivated. 0 0 -
If a call is received from unknown
caller, user ALRNR1 will receive a
SMS with caller‘s number.
1 1 After alarm triggering, users
will be called once.
If calling from user‘s number, after
3-4 calls the system will pick up,
armed mode will remain on.
2 2 After alarm triggering, users
will be called twice.
The user ALRNR1 receives an SMS
message, if GSM connection was
lost for more than 30 seconds. The
message is sent only when in armed
mode.
4 4 If call received not from
ALRNR1-ALRNR5, thus the
calling number is in SIM card
(gate control mode), system
answers the call after 3-4
signals, and user can control
the system with DTMF
instructions. Call
automatically cancelled after
1 minute passes.
Note! If several functions have to be operative, sum of the numbers is used.
E.g.: for all three X functions to be active, X value must be 7 (1+2+4=7).
5.3.2.4. PARAMETER U : RESERVE BATTETY VOLTAGE
In the case of use of GsmAlarm-420 for car protection, it is recommended to use not 12V, but 6V
reserve battery. This will assure reliable charge of reserve battery, independently of the car battery
voltage.
U12:system operates in 12V (premise protection) mode, reserve battery voltage 12V
