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 GTalarm3 module. Several 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, thesiren/bell indicates the completedsystem arming and disarming process (except the arming in STAY mode).
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 todeactivate 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.
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
Central monitoring station
DIAL
The system makes a call to the number specified.
Diagnostic Tool
When using Configuration tool software, you may monitor system inputs/ outputs, view changes of peripheral devices,
instantly configure necessary options, for example, enabling/disabling PGM outputs, etc.
Entry Delay
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.

GTalarm3 User manual V-2022-05-24 5 | EN
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.
Fault
A specific problem or error that prevents the system from working properly. The system comes equipped with self-
diagnostic feature allowing to indicate the presence of any system fault and send SMS text message notification to the
listed user phone number.
iButton key
A unique 64-bit ID code containing chip enclosed in a stainless steel tab usually implemented in a small plastic holder. The
module supports up to 800 iButton keys each holding a unique identity code (ID), which is used for system arming and
disarming.
Installer
a person provided with INST (installer's) password
Master/User Code
Allows to carry out system arming/ disarming as well as minor system configuration and control
Normally closed (NC)
It is a switch that passes current until actuated.
Normally open (NO)
It is a switch that must be actuated to pass current.
Periodic Test Event
Provides the following information on alarm system: date & time, status (armed/disarmed), GSM signal strength, mains
power supply status, temperature value measured by primary and secondary temperature sensors (if any).
Pull-up resistor
Is that it weakly "pulls" the voltage of the wire it is connected to towards +V (or whatever voltage represents a logic "high").
PGM output
A PGM output is a programmable output that toggles to its set up state when a specific event has occurred in the system
or if the user has initiated the PGM output state change manually.
Ping period
Sets period of time defining how often the module sends ping data packet to the server.
Service messages
ARM/DISARM, test, resetting of the system.
SSR
Solid State Relay
SMS forward
System can re-sent all incoming SMS messages to the specified users. It is useful if the GSM operator of the inserted SIM
card sends some useful information (SIM card validation or payment account status and etc.) or it is necessary to monitor
all incoming SMS messages by specified user.
User
It is a person being aware USER password.
Zone
Detection devices such as motion detectors and door contacts are connected to the alarm system’s zone terminals.
Zone state/status
Zone status is a position of a certain zone being enabled or disabled. Meanwhile, zone state points out the condition of a
certain zone, which can either be violated (i.e. In case of alarm) or restored.
+V
Positive power supply terminal.

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 ofthe alarm system isthe
current used by sensors, relays, siren and other
devices. It is most convenient to use power supply
source applied for power supply of security systems
with the option to connect backup lead battery. It is
recommended to mount remote control relays into
sockets. Socketsmay be easily fixed in metal box. It
is necessary to select relays according to preferred
voltage and current.

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.

would therefore seem that any particular device is not guaranteed to meet these specifications. For all the other devices the numbers above are the

GTalarm3 User manual V-2022-05-24 17 | EN
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 that this lowers resistance and is a 'good thing', it actually alters the impedance of the network and makes
it less reliable.All unused wires inthe cat 5 cable should beleft unconnected (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.
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 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.
