xital gsm-t instruction manual. Xital gsm-t user manual Xital gsm 4t connection

Autonomous heating systems are widely used in modern private houses and cottages, as well as in apartments. Not only cosiness and comfort in the house, but also safety depends on their correct work.

After all, even a small breakdown of one of the nodes of heating systems can lead, at best, to the repair of equipment, and at worst, to serious damage to housing and property stored in it.

In order to be able to protect yourself from unforeseen accidents, breakdowns and emergency situations, special electronic alarms are used. One of these systems is Xital GSM 4T, used for automatic monitoring of the operation of domestic heating systems.

Functional purpose

Cellular systems Xital GSM are special electronic devices that, using the mobile network of one of the operators, can notify the owner of the house about an emergency situation that has arisen at the facility.

Also, using the same cellular connection, you can remotely control the actuators heating systems. To do this, use a mobile phone paired with Xital GSM 4T - the instructions included in the alarm package will allow you to quickly connect the phone in a few minutes.

Advantages

  • In addition to monitoring the functioning of heating equipment units, Ksital GSM 4T alarms allow you to notify using SMS messages and voice dialing about the operation of sensors / sensors connected to the inputs of the Ksital 4T electronic unit. These can be motion sensors, sensors for opening windows / doors, glass breaking, sensors for the presence of gas, water, smoke, etc.
  • The text in the SMS message can be individual for each of the available inputs. It adapts to the type of sensor that is connected to the corresponding input. If necessary, text messages can be duplicated by a voice call with an "Alarm" notification. Sending SMS messages is carried out to telephone numbers that are recorded in the memory of the SIM card during the time when the Xital GSM 4T is configured.
  • Special service SMS messages are used to control the operation of equipment controlled by GSM alarms. They act on the controller, which turns on or off the relay system controlled by external mechanisms. For correct use by Xital GSM 4T service commands, the instruction manual describes in detail their correct spelling and functional purpose.

How does the alarm work?

Xital GSM 4T systems include one built-in and 5 remote temperature sensors that perform continuous measurement temperature regime in room. The electronic unit, which is owned by the GSM alarm system Ksital, collects information from all sensors / sensors and analyzes it in accordance with a special algorithm.

If the temperature in one of the zones controlled by temperature sensors goes beyond the set limits, a danger alert will be sent to selected phone numbers. Devices of this series allow simultaneous control of 4 zones. To increase the number of controlled zones, the Ksital 12T series alarm system can be used.

To improve the fault tolerance and reliability of systems that control heating equipment and the situation at the facility, it is practiced to use 2 Xital systems, which are used as “partner devices”. For example, together with Xital 4T, Xital GSM 12T can be used - the instruction describes in detail the possibility of paired use of two alarms.

What actuators are connected?

GSM alarm system Xital GSM 4T allows you to connect up to 3 executive devices. These can be sound sirens, light emitters, valves and locking mechanisms, control devices for air conditioning systems, forced ventilation, smoke removal, and so on.

To connect electrical appliances with an operating power of more than 0.2 kW, special contactors (intermediate relays) with a selected power value should be used. Otherwise, the alarm may fail - then it will be necessary to repair the Xital GSM 4T.

The control of the connected devices is carried out automatically using a microcontroller, which is equipped with the Xital GSM 4T alarm system, or through SMS service commands sent from a mobile phone.

Who can carry out the installation?

Installation of Xital GSM 4T is carried out by specially trained specialists of companies that specialize in the installation of fire and security systems.

In addition, users who are “well acquainted” with electronics can independently install and configure the Xital GSM 4 alarm - the instruction will help you perform these procedures quickly and accurately.

Frequent user questions about the Xital GSM 4T system

What is the difference between Xital 4 and Xital 4T

The Xital 4T version comes with 2 wired temperature sensors pre-configured to work with the system. There are no such sensors in the Xital 4 version (which is why it is cheaper). Also in the "T" version, a special reader with two outputs to the thermal sensor loops is included. Messages about power failure in Xital GSM 4T are sent to all user numbers, and in Xital 4 only to the main number.

Which operator's SIM card should I choose?

The operation of the system is guaranteed for operators using 2G communication networks. Thus, for Moscow and the Moscow region, work on the TELE2 network is impossible. Choose tariffs without a monthly fee and with the cheapest SMS messages.

What heating devices can be controlled by the Xital system

Heating control is possible using almost any boiler or electric convector. The manufacturer of the device is not important, since 99% of heating devices can be connected to the Xital system.

Which xital should I choose to control the BUDERUS boiler

Any Xital with index "T", for example Xital GSM 4T which already has 2 thermal sensors.

Which xital should I choose to organize the security of a house, apartment, office or store

If you do not plan to use the heating control functions, then the Xital version without the "T" index is sufficient. Next, you need to decide on the number of security zones (rooms) and, depending on this, choose the Xital 4, 8, 12 version.

I can not do the installation of the Xital system. Can you install it in my house for me?

Yes, we do professional installation of Xital systems. Our specialists are trained by manufacturers of heating equipment, and there are corresponding certificates in the Installation section. Prices for installation work depend on the complexity of installation and the distance from Moscow and start at 5,000 rubles. For ordering installation we have a valid system of discounts.

In another store, I saw a lower price for Xital, why is it wrong with you

We sell at the official prices of the manufacturer and are the official dealers of the manufacturer. We have our own equipment selection service, technical support for our customers for the entire life of the system, warranty service, installation and repair. Compare with those companies that offer to buy Xital for 500 rubles cheaper and think about what you face in this case. the choice is yours.

Who can benefit from installing the Xital 4T system

You are the owner of suburban real estate heated by boilers, convectors and other heating devices and want to save money. Then a set of GSM control of heating equipment - Ksital GSM 4T - was created especially for you. Thanks to this system, you will save up to 30% or more on maintaining a comfortable temperature in the house.

The manufacturer has adapted the Xital GSM 4T system to the maximum for a quick start. Everything you need is already in the box. The user only needs to read the instructions and connect all the elements from the box into a single whole, and by installing the SIM card in a special slot, make the first start.

1 built-in temperature sensor and 2 external (included) allow you to immediately organize temperature control in three different areas of the room. And in the future, it is possible to expand the control zones with additional wired or wireless temperature sensors. Naturally included temperature sensors are already configured on the control panel, and additional ones can be easily connected if you follow the instructions from the instructions.

What is the cost savings with this system?

The Xital system is connected directly to the "brains" of the heating boiler and controls the heating on by its own temperature sensors. When leaving home, the user sets the minimum temperature (for example, 10 °C), and when arriving, several hours in advance, using SMS, he sets a comfortable temperature (for example, 25 °C). Thus, during the absence, the boiler does not work 90% of the time, saving gas, electricity and other fuels.

Please note that you can separately set the temperatures for day and night mode.

What boilers does the Xital 4T system work with?

This device is able to control the operation of almost any heating boilers, electric radiators and convectors. Among them are such eminent manufacturers as Buderus, BAXI, Protherm and others. Xital GSM 4T is able to control even those boilers that are not amenable to regular control methods.

Even if your house has not one, but several heating circuits, then Ksital can easily cope with this task. It will be able to separately control various circuits (underfloor heating, radiators) according to individual temperature values, and also, when an expansion unit is connected, turn on / off pumps, lights and other electrical appliances.

What else can be implemented using Xital GSM 4T

You can organize a security system and notification of emergency situations at the facility. In the event of a danger, the system will notify subscribers whose numbers are stored in the device's memory with short SMS messages and calls.

In normal operation, the system supports wired sensors, but by completing the system with the Ladoga-BRSHS expansion unit, it is possible to work with wireless sensors.

Complete set of the Xital GSM 4T system

GSM alarm system, 10 telephone numbers for dialing and SMS, 3 built-in relays 5A, power supply 12V, 4 control zones for connecting alarm loops with sensors. Built-in analog temperature sensor.

KSITAL GSM-4T - cellular control system for heating equipment. It is intended for notification via a cellular communication channel about the failure of heating equipment and for remote control of it using a cellular phone.

The KSITAL GSM-4T system has two heating control functions: maintaining the temperature at a level set remotely via SMS, and alerting when the temperature drops below the set minimum value or when the temperature exceeds the maximum set value. On a daily basis or upon request, the system can send readings of all temperature sensors connected to the controller. Remote digital temperature sensors (up to 5 pcs.) can be removed at a distance of up to 100m from the system, operate in the range from -55°C to +125°C with an accuracy of 0.5°C. The system allows you to have information about the temperature at various points of the controlled room, including the temperature of the coolant. One of the sensors, whose number is specified in the settings, is used to stabilize the temperature it measures. This can be either the air temperature in the room, or the temperature of the coolant. The GSM system stabilizes the temperature by turning the heating on and off using one of the built-in relays. Retransmits boiler alarm signals via SMS. Allows remote restart of the boiler. Easily adaptable for control freezers, server rooms, air conditioning systems, signaling that the controlled temperature is out of the acceptable range. Along with this, it supports all the functions inherent in a GSM alarm system: notification via SMS and voice dialer about the operation of security, fire and other sensors, turning on a siren, listening to a room, etc.
The KSITAL GSM-4T system has a wide scope, the ability to create a large number of configurations and settings, but at the same time, exceptional simplicity and clarity of the initial launch and installation. To do this, just insert a blank SIM card into the controller, turn on the 220V power adapter and call from your mobile phone to the number of this SIM card. The controller itself will create the initial “default” settings, templates for the SMS mailing list and the list for voice dialing, by AON it will “capture” your number and add it to these lists. Just a minute after the launch, you just need to call the controller's SIM card number, wait for the call to be reset, and you will receive a response SMS containing information about the status of the inputs, the status of the built-in relays, the temperature at the facility, the system is armed or disarmed, the presence 220V.
Installation is also made easy. No need to solder the connectors, security loops are connected through convenient, easily accessible terminal blocks. If errors were made during installation, then when arming, the system will send an SMS, where it will mark short circuits or breaks for each loop. In the case when it is not possible to lay wires to the sensors at the facility, radio sensors from different manufacturers can be used, while a receiver of the same manufacturer is connected to the KSITAL GSM-4T controller.

Peculiarities:

  • Easy programming without using a computer
  • Possibility to make changes to the system settings remotely via SMS
  • Sending SMS about arming and disarming
  • Measurement and transmission of room temperature, remote control temperature
  • Panic button function

Possibility to send SMS about the setting and removal of control from the object. Sending SMS in case of a critical drop in room temperature. The function of stabilizing the temperature in the room according to a remote task. Uninterruptible power supply function, control of charging of the backup 12V battery, sending SMS in case of power failure 220V and critical discharge of the backup battery. Panic button function that allows you to send alarm SMS when the system is removed from control. Automatic daily report (and also on request) on the health of the system. Putting the system on control both with the help of Touch Memory keys and with the help of SMS. Diagnosis of malfunction of alarm loops (breaks, short circuits) during control. Power supply 12V directly from the controller (maintained in case of loss of 220V). The controller reads the voltage at the inputs of the security zones in analog form and compares it with the values ​​recorded during arming. An alarm for a given zone is defined as a significant (more than 25% of that measured during setting) voltage deviation at the zone input, caused by a change in the loop resistance. Therefore, "Ksital GSM-12T" can work with any sensors that provide a break in the security loop, or its short circuit, or a change in the resistance of the loop. These include almost all security and fire sensors, flood sensors, gas leakage sensors, etc. of any zone according to the list of phones, an SMS is sent, which indicates the number of the triggered zone (default text) or a text previously entered by the user. Then this mailing is duplicated by dialing with a voice message “Alarm! » according to the additional list of telephones, where there may be ordinary landline numbers. If necessary, a relay is simultaneously activated, including a siren, searchlight, etc. The 1st zone has a user-programmable activation delay in the range from 1 to 99 seconds (default 20 seconds). Sensors that control the entrance door and the hallway are connected to this zone. This delay allows the owner of the registered Touch Memory key to disarm the system by applying it to the reader included in the kit and installed in the hallway. Arming and disarming can be accompanied by sending control SMS to the main phone indicating the time. This allows, for example, to control the time of arrival and departure of children from home. The controller includes one built-in and two remote temperature sensors. Remote temperature sensors are connected in series with the Touch Memory reader common cable up to 100m long. Quantity remote temperature sensors can be increased up to 5 pcs. The system is equipped with a power supply that provides power to the controller from the 220V network, as well as charging a backup 12V lead battery. When 220V is lost, the system (and sensors connected to it) are switched to power from the backup battery. At the same time, an SMS is sent about the loss of 220V. Corresponding SMS are sent when the backup battery is discharged and when 220V is restored. By commands sent in the form of SMS, any of the 3 built-in relays can be turned on or off. This makes it possible to remotely control various equipment. Switching on and off is accompanied by sending a confirmation SMS. A system health report containing the status of relays, inputs, readings of temperature sensors and other parameters can be received by SMS request, just by call (if the SIM card supports Caller ID) or daily without a request.
