A distinctive feature of wireless alarm systems is that the tracking sensors communicate with the central unit via a GSM network. To work, a SIM card of the selected operator is installed in it. GSM equipment is a home alarm with a telephone alert. After switching on, the central unit finds all installed sensors and starts taking readings. If one of the sensors is triggered by a movement or another indicator of a violation, an alarm will be sent to the center and a siren will sound, and a message will be sent to the host’s mobile phone.
The device is programmed so that the phone gives a signal until a reception signal is received. The central unit mode 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 fields of production, it is used in offices, private buildings, a GSM alarm system is installed for the house, garden.

Selection Criteria and Price
Having considered the features and technical characteristics of all systems, they select the optimal parameters for installation in the selected room or in the open. 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 for acquiring equipment, but for wireless alarms it is one of the advantages. 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.
The alarm for the house with a telephone alert is selected taking into account 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 configuration, sometimes the equipment warranty is not given. Such systems are cheap, but the quality is poor.

- infrared sensors are placed on the line of a possible passage of a person, at a height of not less than 2 m from the floor surface, the angle of inclination is not more than a right angle;
- the range of reception of the movement of the sensor is about 8 meters, the viewing angle is not more than 110º;
- opening sensors are mounted on a fixed frame, the magnet is placed on a movable leaf, a gap between them of not more than 1 cm is observed;
Next, configure the GSM alarm system for the home. An instruction with a step-by-step description is attached to the device in the purchase configuration.
DIY alarm manufacturing
Craftsmen make a wireless alert when dangerous situations occur on their own phone, which helps to save money. For work, they acquire materials and tools:
- a mobile phone with the ability to quickly dial the selected number;
- a sensor for reading sounds from the surrounding space in the form of a microphone;
- push-button sensor for opening the opening (window or door);
- battery acid-gel type 12V (you can take a battery with a larger capacity, which will increase the battery life in the absence of electricity);
- Accumulator charging;
- soldering iron, solder, pieces of wire.
The alarm system for the house with a telephone alert works by the principle of closing a contact on the cell of one of the digits in the phone, to which the host’s speed dialing is programmed.
Procedure
The number on the keyboard is selected, 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 freed up for work.
To connect the wiring, two cuts are made under the desired button. After raising the film, a 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 wires in the winding, this will reduce the number of pickups and false calls.
To exclude unforeseen short circuits, a small square of insulating tape is glued onto the membrane, closing it. If it is planned to return the phone to normal working use over time, then the membrane will not be removed. The cell phone is ready for use, and then an alarm is set for the house with a telephone notification. To make such a connection with your own hands is not difficult, they are determined with the option of closing two contacts.
Two microcircuits are used: K561LN2 and K561LA7, such an alarm sets the time for the owner to go beyond the boundaries of 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. Do-it-yourself wireless GSM alarm system for the home, expanding the application by installing additional sensors.
Options for connecting the phone to the alarm system
For one of them, a relay with open contacts is used. The relay coil is connected to the alarm output. If an alarm is triggered, then voltage is applied to the winding, the contacts are connected, and the telephone button is pressed, sending a call signal to the owner’s telephone.
The second method is to connect a bipolar transistor directly to the telephone 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 home begins to work. The reviews of those who use such a scheme indicate its sufficient reliability.
To create a decoupled circuit from the point of view of galvanic, it helps to connect the phone with an optocoupler. An optotron is an electronic device containing a light emitter and a photodetector, enclosed in a common single housing. Both components of the optocouplers do not have joint contacts, so the security circuits are powered by different sources without common wires.
All three connection methods are valid when connecting a cell phone to any alarm. A GSM alarm system is installed for the house, garage, and is easily connected to car security.
How to provide uninterrupted power
Apply charging the telephone battery with an ordinary device. This is an easy way, but the battery is constantly in full charge mode, and the lithium battery is gradually being destroyed.
An ordinary phone battery is used, but a fixed power supply voltage of up to 4 volts with a permissible load current of 700 to 1000 mA is used for charging. This power allows you to accumulate in the battery is not the full volume, but only up to 70-75%.
Another option is to refuse a stationary telephone battery and connect a security system to the battery, which is up to 12 volts and is constantly recharged. In this case, a current transformer or transformer is installed. Before connecting such a device to the phone, it is necessary to check the output voltage, which should not exceed 3.9-4.0 volts.
Your home, a working enterprise, a garage, a car must be protected by a perspicacious owner from an attempt to break into and penetrate. Wireless alarm helps to perform this function reliably, economically, without difficulties and problems.
