1.2. Used definitions and terms
Term
Description
Alarm Log
Contains information about alarms that are currently active on the system or information about alarms that have been
raised and then resolved on the system. This log can be useful in analyzing problems and trends in the system.
Arming/Disarming
A process of enabling/disabling system's security.
Authorized user
It is a person whose mobile phone’s number is entered in GSM module. Two authorized users with the same rights may
be entered into the module.
Backup battery
The secondary power source of the system. In case of a main power failure, the backup battery will take over.
Bell squawk
If enabled, the siren/bell indicatesthe completed system arming and disarming process (exceptthe arming in STAYmode).
After the system is successfully armed, the siren/bell will emit 2 short beeps and 1 long beep after the system is disarmed.
By default, the parameter is disabled.
Bypass/Activate Zone
Zone bypassing allows the user to deactivate a violated zone and arm the system without restoring the zone. If a bypassed
zone is violated or restored during exit/entry delay, or when then system is armed, it will be ignored. The zone will remain
bypassed until the system is disarmed. Zones can only be bypassed and activated when the system is not armed.
Caller ID
Caller's identification
COM
Negative power supply terminal.
Confirmation timeout
Specifies the time in which a cross zone must be violated that the system could confirm alarm on the associated zone.
Configuration
Programming of the settings, which will define the operation of the item. For example, user's telephone numbers, set-up of
periodicity for sending SMS message, input names etc.
CMS

Diagnostic Tool
When using Configuration tool software, you may use a section of functions, that allows to monitor real-time zones, view
changes of peripheral devices, instantly configure necessary options, for example, enabling/disabling PGM outputs, etc.
Entry Delay
Once the exit delay has expired, the system initiates the entry delay countdown if a Delay type zone is violated. The
countdown is indicated by short beeps emitted by keypad buzzer and by steady beep emitted by system's buzzer. The
indication is intended to advise the user that the system should be disarmed. If the system is disarmed before the entry
delay expires, no alarm will be caused.
EOL
(End of line resistor) input type with resistor.
Event
The information that the user receives.

Event Log
A list of system events that is uploaded from the device‘s memory to the configuration software for further analysis. The
system logs all information about system configuration, system actions and info messages.
Exit Delay
A period of time intended for user to leave the secured area. The system begins the countdown after the arming process
initiation.

You can find wiring diagrams in the Error! Reference source not found.. You can find detailed information about security system’s
configuration in the Error! Reference source not found.
3.1. Power supply, Battery Wiring

It is possible to supply the security
system from stabilized power supply
source 10-15 V and not less than
1,5A. It is necessary to calculate max
current of power supply. The current
of the alarm system is the current
used by sensors, relays, siren and
other devices. It is most convenientto
use power supply source applied for
powersupplyof securitysystemswith
the option to connect backup lead
battery. It is recommended to mount
remote control relays into sockets.
Sockets may be easily fixed in metal
box. It is necessary to select relays
according to preferred voltage and
current.
Figure 2 Power supply connection
AC equipment cannot be connected directly to the module. It is necessary to use a special relays or other methods, which are in
compliance with electrical safety requirements.
When controlling devices from the AC network, it is necessary to follow all electrical safety requirements.
3.2. Humidity sensors AM2302/DHT22/AM2305/AM2306/AM2320/AM2321

16. Write configuration
Using cat 5 cable is best and will make it easier to maintain a working 1-wire
network when you expand and add more sensors. The data and ground should
use one twisted pair, for example blue/blue-white. A single wire from another pair
is used for the 3.3 volt supply.
Don't double up wires on the assumption thatthis lowers resistance and isa 'good
thing', it actually alters the impedance of the network and makes it less reliable.
All unused wires in the cat 5 cable should be leftunconnected (don't connect them
to ground).When running a 1-Wire bus, Dallas recommend that you use an
unshielded Cat5 cable for the bus. Do not use shielded cable as the capacitance
increase will upset the network.
Figure 24 Sensor’s connection with Cat5 cable
If you intend to have a large 1-Wire network, it is important that you design the network correctly, otherwise you will have problems with
timing/reflection issues and loss of data. You must connect each sensor to a single continuous cable which loops from sensor to sensor in turn (daisy
chain). This will reduce potential miss-reads due to reflections in the cable. Each sensor should have a maximum of 50mm (2") of cable connected
off this main network. Even when using this method, connecting more than 10-15 sensors will still cause problems due to loading of the data bus. To
minimize this effect, place a 100-120Ω resistor in series in the data line of each sensor before connecting to the network. The total length of the bus
from 10 to 100m. Depending of cable quality sensors number on bus, and environment noise. There is possibility to connect up to 32 devices.
Begin the installation by mounting additional devices in the cabinet using the stand-offs provided, then mount the cabinet in a dry, protected
area with access to unstitched AC power. Install hardware in the sequence indicated in the following pages. Do NOT apply power until installation is
complete.
All wiring entry points are designated by arrows. All circuits are classified UL power limited except for the battery leads. Minimum ¼”
(6.4mm) separation must be maintained at all points between power limited and non-power limited wiring and connections.
3.5. Burglar Alarm sensor zones wiring EOL NO NC
The module GTalarm2 has:
4 analog inputs (In1...In4 (0-10V)) for analog sensors connection. Or can be used or use it as security system‘s zones with selectable type:
NC/NO/EOL/EOL+TAMPER.
2 programmable analog inputs (I/O1, I/O2(0-10V/0-20mA)) for analog sensors control or using as security system‘s zone with selectable
type: NC/NO/EOL/EOL+TAMPER
It is recommended to use standard motion, fire, and glass breaking sensors. For powering of sensors we recommend to use standard 6-
8 wires cable for, designed for installation of security system.
Connect security system‘s sensors to module as is shown in connection diagrams below
Set the required parameters
Write configuration by pressing „Write“ icon

The module has 2 I/O analogue input/ output circuits I/O1 and I/O2. They also can be used for burglary alarm zones. Input type: NC/NO/EOL/
EOL+TAMPER. I/O1, I/O2 do not have internal pull-up resistors unlike IN1-IN4. So if you want to use I/O as burglar zones to connect NO/NC/EOL
sensors to I/O1 or I/O2 you have to connect external 5.1K resistor between I/O and +VD, as is shown in attached diagram.
I/O1, I/O2 do not have internal pull-up resistors. So if you want to connect NO/NC sensors to I/O1 or I/O2 you have to connect 5.1K
resistor between I/O and +VD
Please note. If I/O1 set as 2-wire, you don't need 5.1k resistor.

3.6. Guidelines for Locating Smoke Detectors and CO Detectors
The following information is for general guidance only and it is recommended that local fire codes and regulations be consulted when locating and
installing smoke and carbon monoxide alarms.
Smoke Detectors. Research indicates that all hostile fires in homes generate smoke to a greater or lesser extent. Detectable quantities of smoke
precede detectable levels of heat in most cases. Smoke alarms should be installed outside of each sleeping area and on each level of the home.
Additional smoke alarms beyond those required for minimum protection be installed. Additional areas that should be protected include: thebasement;
bedrooms, especially where smokers sleep; dining rooms; furnace and utility rooms; and any hallways not protected by the required units.
On smooth ceilings, detectors may be spaced 9.1m (30 feet) apart as a guide. Other spacing may be required depending on ceiling height, air
movement, the presence of joists, uninsulated ceilings, etc.
• Do not locate smoke detectors at the top of peaked or gabled ceilings; dead air space in these locations may prevent smoke detection.
• Avoid areas with turbulent air flow, such as near doors, fans or windows. Rapid air movementaround the detector may prevent smoke from entering
the unit.
• Do not locate detectors in areas of high humidity.
• Do not locate detectors in areas where the temperature rises above 38oC (100oF) or falls below 5oC (41oF).
Where required by applicable laws, codes, or standards for a specific type of occupancy, approved single- and multiple-station smoke alarms shall
be installed as follows:
(1) In all sleeping rooms and guest rooms.
(2) Outside of each separate dwelling unit sleeping area, within 6.4 m (21 ft) of any door to a sleeping room, the distance measured
along a path of travel.
(3) On every level of a dwelling unit, including basements.
(4) On every level of a residential board and care occupancy (small facility), including basements and excluding crawl spaces and unfinished attics.
(5) In the living area(s) of a guest suite.
(6) In the living area(s) of a residential board and care occupancy (small facility).
CO Detectors. Carbon monoxide gas moves freely in the air. The human body is most vulnerable to the effects of CO gas during sleeping hours. For
maximum protection, a CO alarm should be located outside primary sleeping areas or on each level of your home.
The electronic sensor detects carbon monoxide, measures the concentration and sounds a loud alarm before a potentially harmful level is reached.
Do NOT place the CO alarm in the following areas:
• Where the temperature may drop below -10ºC or exceed 40 ºC.
• Near paint thinner fumes.
• Within 5 feet (1.5 meters) of open flame appliances such as furnaces, stoves and fireplaces.
• In exhaust streams from gas engines, vents, flues or chimneys.
• In close proximity to an automobile exhaust pipe; this will damage the detector.
GTalarm2. Begin the installation by mounting additional modules in the cabinet using the stand-offs provided, then mount the cabinet in a dry,
protected area with access to un switched AC power. Install hardware in the sequence indicated in the following pages. Do NOT apply power until
installation is complete.

More information about how to configure the zones: Zones programming

Install the 4-wire smoke detectors with 18 gauge wire. If power is interrupted, the relay causes the control panel to transmit the Fire Loop Trouble
report. To reset (unlatch), connect the smoke detector’s negative (-) to a PGM.
The parameters of the zone should be defined as a “Fire Zone”. If a line short occurs or the smoke detector activates, whether the system is
armed or disarmed, the control panel will generate an alarm. If the line is open, the “Zone Fault” report code is sent to the monitoring station or to the
user, if programmed.
1. Connect the [4-wire] smoke detector.
2. Connect the power supply.
3. Install SERA2 software.
4. Go to “Burglar Alarm Zones” window. Double press on required input. Set “Zone definition” to “Fire”.
5. Write configuration by pressing “Write” icon.
3.6.2. [2-Wire] Smoke Detector Wiring to I/O Inputs
The 2-wire Smoke zone on the module is the only zone in the system that can have 2-wire smoke detectors as Fire Alarm initiating devices. This
zone is an end-of-line EOL 2.2Kresistor type and can accommodate up to 30 compatible 2-wire smoke detectors. The zone is fixed as a 2-wire smoke
zone. I/O 2-wire smoke zone is trouble supervised zone. The zone wiring is supervised by the control panel.
The parameters of the zone should be defined as a “Fire Zone”. I/O1 and I/O2 can be defined as a 2-wire smoke detector input if a line short
occurs or the smoke detector activates, whether the system is armed or disarmed, the control panel will generate an alarm. If the line is open, the
“Zone Fault” report code is sent to the monitoring station or to the user, if programmed.

3.7. Outputs. Bell & PGM Wiring
The module GTalarm2 has:
4 open drain (1A) outputs: OUT1 (1A)… OUT4 (1A). The outputs can be used for siren, relay, lamp connection. These outputs can be
controledvia short callor sms. Output operation algorithms: Automation /CTRL, Siren, Buzzer,ARM state, Zones OK, Light Flash, inverting,
pulse mode
2 open drain (20mA) outputs: I/O1 (20mA)… I/O2 (20mA). These outputs can be used for solid state relays, LED, to control devices up to
20mA.
3 outputs: D1 (10mA, Max Voltage 3,3V) for LED, solid state relays control. Max voltage 3,3V
1 programmable output BUS. Voltage 8-15V, Current 20mA

All outputs can be controlled via short call DIAL or via SMS message. This feature may be used for gate opening, ignition locking etc.
Output alarm parameters may be programmed.
Programmable algorithms for outputs operation: CTRL/SMS/DIAL, SIREN, BUZER, ARM state, Zones OK, Light Flash, inverting, pulse
mode
Output switch to ground when activated from the module. Connect the positive side of the device to be activated to the VD+ terminal. Connect the
negative terminal to the selected output.
1. Connect devices to the selected outputs as shown in the figures below. For sound signaling we recommend to use siren DC 12V up to
1500mA. It is recommended to connect the siren to the system by using 2 x 0,75 sq. mm double insulation cable. Auxiliary BUZZER is
recommended to be installed inside the premises not far from the entrance. Buzzer operates together with the main siren also when the
system starts calculating the time to leave the premises and the time till alarm response of the security system after entering the premises
(see clause 7.1). It is possible to use buzzer of hit point PB12N23P12Q or similar modified piezoelectric 12V DC, 150mA max Buzzer.
Standard AC/DC adapter with the voltage 10V-14V and current >=1A might be used to powering the module

3.8. Access control. Arming/ disarming methods
General operation description
When the system is being armed, it will initiate the exit delay countdown intended for the user to leave the secured area. During the countdown
period the buzzer will emit short beeps. By default, if there is at least 1 violated zone or tamper, the user will not be able to arm the system until the
violated zone or tamper is restored. In case it is required to arm the alarm system despite the violated zone presence, the violated zone can be
bypassed or Force attribute enabled.
After the system is armed and if a zone (depending on type) or tamper is violated, the system will cause an alarm. During the alarm, the siren/bell
will providean alarm sound along with the buzzers of the keypads. Bydefault,the system willalso makes a phone calland send an SMS text message
containing the violated zone or tamper number to a listed user phone number and indicate the violated zone or tamper number on the keypad. If
another zone or tamper is violated or the same one is restored and violated again during the alarm, the system will act as mentioned previously, but
will not extend the alarm time.
After the user enters the secured area, the system will initiate the entry delay countdown intended for system disarming. During the countdown
period, the buzzer will emit a steady beep.
The alarm will be caused even if a tamper is violated while the system is disarmed
The system features the following methods to carry out arming and disarming process:
Free of charge phone call
SMS text message
Wiegand keypad user code
Wiegand RFID key card, keyfob
iButton key
When the system is successfully armed or disarmed, it replies with confirmation by SMS text message.
Due to security reasons it is highly recommended to restore the violated zone/tamper before arming the system.
Arming process:
If ready (no violated zone/tamper), the system will arm.
If unready (violated zone/tamper is present), the system will not arm and provide a list of violated zones/tampers by SMS text message to
user phone number. In such case the user must restore all violated zones and tampers before arming the system. Alternatively, the violated
zones can be bypassed, disabled or a Force attribute enabled, and the tampers can be disabled when arming. The system initiates the exit

delay countdown intended for the user to leave the secured area. When the security system is to be turned in ARM mode, the bell will beep
once, when in DISARM mode - the bell will beep twice.
Arm/Disarm by call
It is possible to arm, disarm the system and turn OFF the alarm by dialing the system‘s phone number from any of 800 available user
phone numbers The system ignores any incoming calls from a non-listed phone number .The phone call is free of charge as the system
rejects it and carries out arming/disarming procedure afterwards. If there is more than one listed user dialing to the system at the same
time, the system will accept the incoming callfrom the user who was the first to dial while other user (-s) will be ignored. To disable/enable
arming or disarming for certain listed user phone numbers, please mark near ARM/DISARM in the “Users & Remote control” window
Arm/Disarm by sms
The system ignores any incoming SMS text messages from a non-listed phone number as well as it rejects the SMS text messages
containing wrong SMS password even from a listed user phone number. To arm the system by SMS text message, send the following
text to the system‘s phone number USER 000000˽030˽ST
030= command code (Change security system’s mode (ARM/DISARM/STAY/SLEEP)
ST = Security system mode 0-DISARM, 1-ARM ,2-STAY ,3-SLEEP
Arm/Disarm by keypad
To arm/ disarm the system by Wiegand Keypad, enter User/Master Code
To cancel the arming process: Enter the user/master code again during exit delay countdown.
Disarming the System and Turning OFF the Alarm To disarm and turn OFF the alarm, enter any out of available user codes or master
code using the number keys on the keypad.
Arm/Disarm by iButton key
To arm or disarm the system and turn OFF the alarm, touch the iButton key reader by any of 800 available iButton keys. When the
iButton is touched to the iButton key reader for arming/ disarming, the system will proceed arming/ disarming process.
Arm/Disarm by RFID key card, keyfob
To arm/disarm the system with RFID keycard, touch 1 of 800 RFID keycard to theWiegand keypad.When the RFID keycard is touched
to the reader for arming/ disarming, the system will proceed arming/ disarming process.
