A distinctive feature of wireless alarm systems is that tracking sensors communicate with the central unit via a GSM network. To work in it, a SIM card of the selected operator is installed. GSM equipment is a home alarm system with telephone notification. After switching on, the central unit finds all installed sensors and starts taking readings. If one of the sensors is triggered by movement or another indicator of violation, then an alarm is sent to the center and a siren sounds, and a message is sent to the owner's mobile phone.
The device is programmed so that the phone will beep until the receive tone is given. The mode of the central unit is set by the owner, each zone is programmed for a specific signal, and when it arrives, it becomes clear in which sector the tracking sensor is triggered. The equipment is installed in various areas of production, used in offices, private buildings, GSM alarm systems are installed for houses, cottages.

- wireless system works easily in homes and detached premises that do not have telephones and electricity;
- no monthly fee is paid for a quick response and the arrival of a security detail, the signal instantly notifies the owner, and he acts at his own discretion;
- The design of the system provides protection against false response to the movement of insects and animals, which is very valuable compared to conventional equipment.
Component parts
The device comes with a standard or extended version. The standard scheme is equipped as follows:
- tracking sensor;
- door or window opening alert sensor;
- siren device;
- set of keyrings.
Standard equipment is expanded with an additional number of sensors, and additional notification devices are added gradually after the installation of the main equipment.

Selection criteria and price
Having considered the features and technical characteristics of all systems, they choose the optimal one in terms of parameters for installation in the selected room orin open area. For large areas, systems with the ability to connect a large number of sensors are used, but such kits are more expensive. Small economical rooms, garages are protected by small functional systems to reduce the cost due to a small number of sensors.
Price is often a determining factor in purchasing equipment, but for wireless alarms it is one of the strengths. On average, the cost of a standard set is about 7-11 thousand rubles, which makes it affordable for the general population. This is a low price for acquiring peace of mind for your property, with the condition of prompt notification in connection with violations.
Alarm for home with notification by phone is selected based on the name of the manufacturer and the country of production. Chinese lightweight models are equipped with a low-quality plastic case, often there are no batteries in the package, sometimes the equipment warranty is not given. Such systems are cheap, but the quality leaves much to be desired.
Security equipment is selected based on functionality, the best set is a GSM alarm system for the home, it instantly transmits a signal to the owner's phone and allows him to react very effectively. If the system is equipped with a siren, then strangers will not want to be in the apartment even after a successful break-in.
When choosing, they take into account the possibility of connecting wired systems, battery capacity, and a convenient screen with a clear interface. Focusing on thesedata, choose the optimal solution for the protection of the object. Important in the kit are additional functions, such as temperature control, network voltage.
Connection instructions
GSM security alarms for the home are easy to install, which will not take much time even for an unprepared user:
- selecting a place to install the central control unit;
- tracking sensors are mounted in the places of their controlling purpose, preferably at an equal distance from the central unit;
- infrared sensors are placed on the line of possible passage of a person, at a height of at least 2 m from the floor surface, the angle of inclination is not more than a right angle;
- receipt range of the sensor movement - about 8 meters, viewing angle - no more than 110º;
- opening sensors are installed on a fixed frame, the magnet is placed on the movable sash, the gap between them is not more than 1 cm;
Next, the GSM alarm system for the house is configured. A step-by-step instruction is attached to the device in the purchase package.
Making an alarm with your own hands
Craftsmen make a wireless notification in case of dangerous situations on their phone with their own hands, which helps to save money. For work, they purchase materials and tools:
- mobile phone with the ability to quickly dial the selected number;
- sensor for reading sounds from the surrounding space in the form of a microphone;
- push-button sensor for opening opening (window or door);
- 12V acid-gel type battery (it is allowed to take a battery with a higher capacity, which will increase the battery life in the absence of electricity);
- battery charging;
- soldering iron, solder, pieces of wire.
A home alarm with phone alert works on the principle of closing a contact on the cell of one of the digits in the phone, which is programmed with the owner's speed dial.
Procedure of actions
A number is selected on the keyboard, the ability to quickly dial is configured in the phone functions. To avoid surprises in the future, speed dialing is checked when a key is pressed. After that, the back surface of the mobile phone is removed, then the front part with the screen is removed, and the board, protected by a white film, is released for work.
To connect the wires, two cuts are made under the desired button. After lifting the film, the metal membrane located on the inside becomes visible. This part performs the function of closing two contacts, the midpoint and ground. The wire is soldered to two contacts, it is advisable to take one so that there are two cores in the winding, this will reduce the number of pickups and false calls.
To prevent unexpected short circuits, a small square of insulating tape is glued onto the membrane, closing it. If it is planned to eventually return the phone to normal working use, then the membrane is not removed. The cell phone is ready for work, and then it is installedalarm system for the house with the notification by phone. It is not difficult to make such a connection with your own hands, they are determined with the option of closing two contacts.
They use two microcircuits: K561LN2 and K561LA7, such an alarm sets the time for the owner to leave the protected object and determines the period for the owner to enter the territory to turn off the alarm. At this time, there is a delay in responding to movement and other parameters. DIY wireless GSM home alarm system expands the application possibilities by installing additional sensors.
Options for connecting the phone to the alarm system
One of them uses a relay with open contacts. The relay coil is connected to the alarm output. If an alarm is triggered, voltage is applied to the coil, the contacts are connected, and the phone button is pressed, sending a call signal to the owner's phone.
The second way is to connect a bipolar transistor directly to the phone keypad. The output of the transistor is in contact with a common wire, and its collector is connected to a push-button contact. The voltage is supplied to the transistor base through a resistor and the GSM alarm system for the house starts working. Feedback from those who use such a scheme speaks of its sufficient reliability.
Creating a decoupled circuit from the point of view of electroplating helps to connect the phone using an optocoupler. An optocoupler is an electronics device containing a light emitter and a photodetector enclosed in a commona single body. Both components of the optocoupler do not have common contacts, so security circuits are powered from different sources without common wires.
All three connection methods are valid when connecting a cell phone to any alarm system. Installed GSM alarm system for home, garage, easily connected to car security.
How to provide uninterruptible power
Used to charge the phone battery with an ordinary device. This is an easy method, but the battery is constantly in full charge mode, and the lithium battery is gradually degraded.
An ordinary phone battery is used, but a fixed power supply voltage of up to 4 volts is used for charging with a permissible load current of 700 to 1000 mA. Such power allows you to accumulate in the battery not the full volume, but only up to 70-75%.
Another option is to ditch the fixed telephone battery and connect to the security system battery, which is up to 12 volts and constantly recharges. In this case, a current converter or transformer is installed. Before connecting such a device to the phone, be sure to check the output voltage, which should not exceed 3.9-4.0 volts.
The perspicacious owner must protect his home, work enterprise, garage, car from breaking and entering attempts. A wireless alarm system helps you to perform this function reliably, economically, without difficulties and problems.
