Radio channel security systems. Radio channel alarm systems Radio channel alarm systems

If your choice is a GSM radio channel alarm, then you will receive the most modern technologies ever used in security systems. This type of signaling has become widespread, because it does not require laying wires and cables, and therefore the connection of sensors cannot violate the integrity of the walls and ceilings of the room. It is convenient to use it if you need to protect buildings that are architectural monuments, old brick buildings, temples, modern and historical churches (no one will spoil the walls painted with frescoes), buildings with thickened walls and for objects that cannot be accessed lay the cable.

Of particular note is the convenience of wireless security for people who often change their place of residence. Every time, in a new place, laying a cable is too expensive.

Any radio channel security alarm system is completely autonomous and is not affected by the lack of electricity. Reliable battery power keeps the sensors operational at all times, no matter the circumstances.

Advantages of radio channel alarms

There is no need to obtain special permits for the use of radio frequencies.
One radio channel alarm allows you to arm several objects.
Using the keyboard or key, you can arm and disarm this or that object without the help of specialists.
A modern radio channel fire alarm operates at a distance of up to 10 km on rough terrain, and up to 20 km in open areas.
Ease of management.
Interference resistance.
Large operating temperature range./li>
Control of all power sources.

Numerous positive reviews indicate that radio channel alarm systems are very popular, and the price at which you can buy the system remains very affordable and affordable. If we compare this type of protection with systems where wires are used, then it will cost less, because it is not necessary to buy an expensive cable, which often has to be changed after each winter period.

Detection and notification are the two main components of systems of this type, therefore the company "Sintez Security" recommends that the sensors be located in such a way that they are inaccessible to unauthorized people.

Also, this type of protection is often chosen by the owners of garages. In this case, the sensor is installed directly in the garage, and the receiver is at your home.

Question: Where is radio signaling used?

Answer: Radio signaling (wireless signaling) is widely used for the protection of private residential and industrial premises. The principle of operation of a wireless alarm system is based on the transmission of an alarm signal from a detector to a control device via a radio channel.
Wireless burglar alarm allows you to control unauthorized entry into a protected area and notify the owner about it. Also, using a wireless alarm, you can monitor the temperature in the room, learn about the leakage of water or gas.
Wireless fire alarm promptly notifies of smoke or the occurrence of a flame (fire).

Question: What are the advantages of wireless alarm?

Answer: The main advantage of wireless signaling is that there are no wires in such a system, and therefore the need to drill walls and lay cables. Other advantages include ease of installation, ample opportunities for expanding the system, and relatively low cost.

Question: How to choose a wireless alarm system for your home?

Answer: For the protection of the house (apartment), a radio channel security and fire system is well suited. This system contains the main security and fire detectors, the control panel and other devices necessary for home security.

Question: How to choose a radio alarm for the garage?

Answer: To solve this problem, the RS-200TP radio channel transmitter and the RS-200R receiver are usually used. The necessary security and fire detectors, power supplies, annunciator and cable are selected for them. Such a radio alarm for the garage allows you to notify the owner in time about the penetration of unauthorized persons into the garage or the occurrence of a fire.

The radio channel security alarm system is rightfully considered the most modern means of protection against unauthorized entry into housing. It differs from classical complexes by the absence of electrical wiring to power the sensors and the operation of the sensors due to autonomous accumulators or batteries. Thanks to this, the operation of the system will not be disturbed by a power outage or, conversely, too high voltage in the network. In addition, radio channel devices do not require only professional installation, but can be installed by yourself.

Radio channel security alarm systems of the DIY category

DIY (“Do It Yourself”) devices require self-assembly and configuration, without requiring any skills or knowledge for this. They feature a pleasing ergonomic design and a user-friendly digital display interface where all sensors can be configured. The interaction of the main unit and tracking devices is based on a radio signal, eliminating the need for laying wires for power and signal transmission.

To install an alarm system, even the simplest one, you need to create a project for it, on which the locations of the sensors and the location of the power supply loop of the central control unit will be marked. This does not require any permits, as when laying power cables, since the power of the installation does not exceed 10 mW. Therefore, when choosing a radio channel security alarm, special attention should be paid to the selection of high-quality signal receivers and response sensors, which will ensure the safety of the home. Special attention should be paid to power supplies for autonomous operation of tracking devices, without which the safety of property and people may be at risk.

Installing a DIY category system will not be difficult even for an unprepared user who does not have any knowledge in this area. The manufacturer indicates the algorithm of the necessary actions for installation and configuration in the instructions for the device, describing in detail all the stages of the processes.

Radio channel systems PRO

Today, many companies work in > Like any other complex system, wireless radio channel alerts have a number of advantages and disadvantages that should be considered when deciding to purchase such a complex to protect your home or office.

Among the advantages of the system are:

no need for cable laying;
the possibility of self-installation and configuration of operation parameters;
the ability to connect several objects at once for protection;
the ability to remotely control the work using a remote control key fob;
the use of closed radio frequencies that are resistant to interference;
high speed of signal transmission from sensors to the main control unit;
the ability to control all power sources of the system;
ability to work at temperatures from - 30 to + 50 without interference and failures;
a wide range of sensor response types (smoke, glass breaking sound, movement, etc.).

These advantages make the use of wireless security systems just as effective, but more convenient than wired ones. However, do not forget about the shortcomings, among which.

As for the definition, it is quite obvious - this is an alarm system that uses a radio channel to transmit various notifications.

Radio channel security alarm systems can be divided into two groups:

object;
console.

The first ones are intended for wireless transmission of data on the status of security detectors installed at the facility to the control panel. The second option provides for the exchange of information between the centralized security console (CCP) and the object part of the alarm system equipment.

The main technical characteristics of radio channel equipment are the operating frequency and power. The range of interest to many is a rather arbitrary value, since it can depend on various factors:

terrain;
the nature and presence of various obstacles to the propagation of the radio signal;
in some cases - weather conditions.

Thus, ceteris paribus, the parameter that determines the communication range will be the power of the transmitter.

It is worth knowing that the use of radio frequencies in our country is regulated by regulatory documents that require obtaining an appropriate permit. However, there are bands that are open for free use when the power of the radio transmitter is limited.

Taking into account the interests of the mass user, manufacturers of security alarms operating over a radio channel produce equipment that meets these requirements.

FACILITY RADIO CHANNEL SECURITY EQUIPMENT

The composition of wireless security alarm systems installed at the facilities includes:

radio channel sensors (detectors);
radio transmitters;
radio channel receivers;
repeaters.

This is the most complete list of equipment. In practice, wireless alarm systems most often use detectors with built-in transmitters and receivers. The latter can be combined with a receiving control device.

RF sensors are equipped with built-in batteries, which provides them with autonomous operation and ease of installation. All of them are addressable devices and can be uniquely identified by other components of the security system. Before installation, it is required to assign individual addresses to all radio channel devices.

In addition, the compatibility of all alarm devices with each other must be ensured. This applies to both the operating frequency and signal encoding methods. Therefore, equipment of the same model range should be used.

Batteries for radio channel sensors are best used from those recommended by the manufacturer. This ensures the duration and reliability of the detectors. By the way, it is better to choose models that have the function of monitoring the level of supply voltage with the ability to notify when it drops below an acceptable level.

The most popular wireless object equipment are products of Teko firm. It offers the user sets of devices of several model ranges:

Astra-RI;
Astra RI-M;
Astra-Zitadel.

In addition, brands can be noted: Visonic Power Max, Jablotron.

The most popular among such systems are radio alarm systems. They include radio channel key fobs and receivers. Indeed, it is very convenient and the emergency call button is always at hand. These are products "Astra R", "Leader", etc.

Since the popularity of such equipment is constantly growing, manufacturers are also trying to keep up, constantly expanding the range of products, introducing new technologies and developments.

CONSOLE RADIO CHANNEL SYSTEMS

If the alarm used is not autonomous, then information about its status must be transmitted to the centralized security console. Such a system includes:

object transmitter;
console equipment;
antennas.

Technically and organizationally, this option is more difficult. First, the signal must be transmitted over considerable distances, measured in kilometers. For this, powerful receivers, remote antennas, including directional ones, repeaters are used.

To ensure stable communication, radio channel object transmitters are produced with the maximum allowable power (about 5-10 W). To increase the reliability of protection, it is necessary to provide control of the communication channel (periodic polling of the alarm status at the facility).

Considering that the console can display information about the status of dozens and hundreds of systems simultaneously, this task requires significant time and hardware resources.

But the main inconvenience is the need to use overall receiving antennas, installing them at a considerable height, respectively, using long lines of reduction and matching them. This leads to the fact that the use of the radio channel in its pure form for notification systems is becoming less popular.

This is also facilitated by the expansion of the coverage area and the sufficiently high reliability of the networks of mobile operators. Strictly speaking, GSM signaling is also a radio channel system, but recently it has been increasingly distinguished as a separate direction of wireless data transmission.

It is not surprising that almost all manufacturers specializing in the production of "classic" radio channel signaling use GSM technologies as an alternative.

An example is the "String" radio system. About 10 years ago it was a "clean" radio channel, but today we have a whole line of GSM devices. Other players do the same, for example, Ospas and Altonika.

Moreover, for individual protection (without the use of ARC), there is no alternative to GSM equipment yet.

This security system has become popular due to the fact that the sensors do not need wiring (cables) for switching with the control unit (receiver).

The system works constantly, regardless of the availability of electricity. The redundant power supply and batteries installed in the detectors ensure uninterrupted operation of the entire system. This proves reliability and efficiency in operation.

Even many security companies prefer to have their own centralized security system, which will not require additional periodic expenses for operation, maintenance, and will not depend on third parties.

The transmission of an alarm message over a radio channel remains an effective way to organize security. This type of alarm is designed to protect:

Houses, cottages, apartments, offices, garages;
Objects in motion (protection of individuals, vehicles during the transportation of goods).

A typical alarm configuration consists of two parts: a transmitter with sensors and a receiver. The transmitter and sensors are installed directly on the protected area, they form a message about the state of the system, and periodically send it on the air.

The receiver receives messages and displays the current state of the object and the state of the autonomous power supply with LEDs or on the LCD. The receiver is equipped with an external control device.

In case of loss of communication, the receiver turns on an alarm after half an hour, which will allow detecting malfunctions (antenna cable break, battery failure).

Such a loss of performance can be caused by the appearance of continuous radio interference at the operating frequency.

Principle of operation

In case of receiving an alarm signal from the sensor in case of unauthorized entry through the door, window, when an outsider appears around the perimeter of the territory, when triggered, or if the client presses the “Call security” button, the sound signal is activated until the user turns it off on their own.

If during operation it is not desirable to give an audible signal, it is necessary to turn off the signal and leave only the LED indication.

Installation

For installation, additional skills are not required, school knowledge of physics and a “garage” set of tools will suffice. At the first stage, a draft design is created with the placement of the necessary sensors on the objects.

As for the selection of equipment, here you can’t do without masters, only the knowledge of specialists will help you choose power supplies, sensors and other equipment of excellent quality, because your safety largely depends on their work.

The security system is operated in two separate directions: alerts (, smoke,), detection (, volume, etc.). It is placed in such a way as to limit access to it by unauthorized persons as much as possible.

The installation location of the whip radio antenna is determined empirically, having achieved reliable reception of the radio signal.

It is located at the maximum distance from electrical wiring and massive metal structures (window bars, safes, shelving, heating system pipes), at least half a meter from reinforced concrete ceilings.

The best location for the receiver will be a place near the window, which is directed towards the protected object (the lattice on the window reduces the range of radio reception).

If the range of the alarm with a standard whip antenna is not enough, you will need to install an external antenna. It is indispensable in the conditions of urban development, when placing the receiver inside reinforced concrete premises.

The correct choice (by experience) of the installation location of the receiver and antenna will significantly increase the range and reliability of radio signal reception. The seat selection is checked in the test signal mode.

A sign of a stable transmission of the radio signal will be high-quality reception without gaps for several minutes.

With GSM module

This is also intended to implement a typical wireless security solution using a radio system as the main equipment.

The transmission of alarm and information notifications about events at the protected object is carried out via a radio channel to the receiver, where the sound and light alarms are turned on.

In addition, due to the presence of a GSM module, the information received by the central receiver is duplicated on a mobile device, and repeaters can be used in the country.

A radio channel system with a GSM module and autonomous power supply will notify the security company and the owner of the protected object by mobile phone about unauthorized entry into the protected object, opening or deliberate disabling, sensor battery discharge, arming or disarming the object.

Arming and disarming is also carried out by entering the key on the receiver's remote control or remote control.

The use of the GSM channel as a backup to the radio channel system expands the possibilities of the client himself to control the state of the object and independently manage the security.

The disadvantage is the unsatisfactory noise immunity and suppressibility of the GSM channel. This GSM module is mainly used for duplication of an (additional) communication channel.

Pros of wireless burglar alarms

This device is installed in hard-to-reach places where laying of cable routes and communications is unacceptable.

When using radio channel signaling, you get the following benefits:

The operation of radio channel signaling does not require permission from state authorities to use radio frequencies;
Allows the organization of protection of several objects at the same time;
The complete absence of cable communications and hidden wiring;
To arm / disarm the object, a special key is used or a code combination must be entered from the keyboard;
Works over long distances. In the city, this distance is up to 10-12 km, in open areas it is able to work reliably at a distance of 20-25 km;
Resistant to interference;
The period of signal transmission to the actuator takes seconds;
Reliably operated year-round and does not depend on temperature (from -30 to + 50С - operating temperature range);
Installation is carried out independently, it is very simple to manage.

Like any equipment, the radio channel alarm system has some difficulties in operation:

Limited range, the sensor of the protected object is located at a small distance. The distance is measured in hundreds of meters, although this is enough to protect a private garage or remote office space;
The control panel (receiver) is accessible visually, i.e. before your eyes;

The distance to the protected object is significantly reduced if there are tall structures and buildings in the way of the radio signal. Although this problem is easily solved by installing special additional antennas.

But technology does not stand still, it moves and develops, so such shortcomings are no longer significant. The cost of radio channel signaling equipment still plays an important role, but considerations of personal safety, reliability and quality are gradually coming to the fore when choosing among such equipment.

The development of systems that transmit information over cellular networks increases the benefits of signaling, offers many additional features, significantly increases the functionality and efficiency of security in general.
