A household gas detector is a device that can save your life. Do you need a household gas contamination detector? Who should install a household gas detector?


Gas alarm mounted on the wall in the place where gas leakage is most likely (near the boiler, gas column or meter, near gas stove). Horizontal distance from gas equipment should not exceed 400 cm.


The installation height depends on the density of the gas. Propane is heavier than methane and carbon monoxide and therefore accumulates close to the floor. If you decide to install not only gas alarm, but also a shut-off valve, then you need to contact a specialized company that has a license for such work.

Installation(installation)automatic control systems gas pollution (SAKZ) requires high qualification and a number of specific knowledge. Even at the planning stage, it is necessary to carefully examine the room in which the control devices will be installed. Particular attention should be paid to places where gas can accumulate (niches, recesses). The project should in no case allow the presence of "dead zones". Signaling devices and concentration meters must control the entire room.

The distance from the sensor to the ceiling must be at least 10-20 cm.

As can be seen, the purchase installation (installation
for every family. As for its necessity, it is obvious. Such a small and inexpensive device can prevent terrible accidents associated with the death of people and the destruction of buildings.


In an apartment or house, many appliances run on gas. It is for this purpose that a gas alarm is installed in the room. The principle of its work is simple. When a problem is detected, it lets you know about it with a specific signal. For greater safety, it is recommended to install a shut-off valve.

The gas content sensor monitors the level of combustible gases in the air. When the indicators exceed the norm, the gas detector lets you know about it with special sound and light signals. Such analyzers are widely used in industrial plants, boiler rooms and even in home apartments.

Household sensors are able to detect methane, propane and carbon monoxide in the air.

That is why the determining sensor can be divided into industrial and household. Industrial options have a more complex structure. The kit includes a control panel and the device itself. The household gas trap is simpler in structure and use.

Carbon monoxide is the most dangerous. Unlike other components, it cannot be recognized by smell or color. It quickly combines with hemoglobin and enters the bloodstream. Carbon monoxide can quickly lead to death.

Functions of gas alarms:

  • Notification with light and sound about the problem;
  • Has a hole for connecting additional communications: annunciators, fans;
  • Can be connected to a solenoid valve and turn off the gas supply;
  • Can work autonomously.

Different models from different manufacturers have a unique device. The purchase should be made based on your own needs. But in general, the devices are universal in their functions.

The principle of operation of gas leakage sensors

Principle of operation different types slightly different. Conventionally, all signaling devices are divided into wired and wireless. This speaks to the source of their nutrition. But behind the leak detection technique, there is another classification of sensors.

Types of gas detectors:

  • Semiconductor;
  • catalytic;
  • infrared.

The principle of operation of the catalytic device is to change the platinum coil as carbon monoxide passes through the device. Other coil with measuring instrument used to determine the rise in temperature. There is a direct relationship between resistance and the amount of carbon monoxide particles.

So that the coil does not react to factors external environment, at different ends of the chain there are thermally matched balls covered with glass. They act as a compensator.

Semiconductor devices are a bit similar to catalytic devices in terms of the principle of operation. Recognizing element coated with a thin film of metal oxide. When carbon monoxide touches the film, it absorbs the substance and changes the resistance to an inverse proportion. This option is great for the home, but rarely used in industry. It is believed that the signaling is not accurate enough. In addition, the device has a slow response.

Infrared sensors are widely used for industrial buildings. They are quite accurate, do not squeak unnecessarily, use little energy and quickly respond to a possible leak. They work under the influence of solar energy.

Types of carbon monoxide sensors

There are 2 main types of gas alarms: industrial and household. Industrial sensors are more complex in design, because it is necessary to control a large area. Several devices and a common control panel are provided.

The home sensor is easier to install and use. It should not show the number, but signal a clear problem. To do this, the device begins to emit a special signal and light.

Types of sensors for determining gases:

  • Methane;
  • Propane;
  • Carbon monoxide.

But there are also combined devices that control several concentrations at once. For a room with gas appliances, it is the combined types that should be installed. If in the house stove heating, then one sensor with detection of carbon monoxide leakage is also suitable.

Sensors begin to react if 0.1-1% methane, 0.46-0.05% propane and 0.005-0.01% carbon monoxide are detected in the air.

When buying an alarm, you must consider the power of the system. Also take into account the devices with which it will interact. The optimal indicator is 220 watts.

Acquisition of a gas contamination sensor and a shut-off valve for the boiler room

The shut-off valve is a device that is installed at the inlet of the gas pipeline. It works when an electrical impulse is applied to its coil. At this time, it must cut off the supply of natural gas to all devices.

Distinctive features of the shut-off valve:

  • Nominal gauge. It can be from 15 to 25 mm for domestic needs.
  • Power supply. For home use, the best option is 220 watts.
  • Permissible pressure. For low pressure gas pipelines, the optimal indicator is 500 Mbar.
  • There are different types of valves. It happens normal in the open state and closed.

Normally open is also called impulsive. It is a manually operated element. During operation, its coil does not receive an electrical impulse. When the gas sensor acts on the coil, a small voltage is supplied from the device. This triggers the sensor and shuts off the gas supply.

It is the type of valve that is the decisive characteristic for operation in combination with a gas contamination sensor.

A normally closed device also applies to manual cocking devices. But in order to start its work, it is necessary to apply an impulse to its coil. When the alarm is triggered, the voltage on the coil is extinguished and gas is cut off.

An excellent home valve is a normally open device with a power supply of 220 watts. So turning off the power will not cause it to trip. This makes it possible to use independent gas appliances. This can save on electricity.

Difficulties in synchronous operation of the sensor and the valve may arise when, when turned on, the analyzer starts checking the status of its outputs. The alarm will apply voltage to the valve and cause it to operate. That is why the analyzer in the boiler room needs to be familiarized in detail with the principle of its operation.

Installing a gas sensor with a valve

The good news is that all work on installing the device can be done. It is necessary to choose the right installation site, based on the instructions and conduct power supply to it. Auxiliary devices should be connected according to the diagram, which is indicated in the instructions.

The gasification projects contain all the necessary information on the location of the devices. The gas service will also be able to help in this matter, based on the standards. The gas trap should be installed on a vertical surface where there is increased risk gas leaks. At the same time, it is important to observe a distance of 4 m from gas appliances.

Rules for the correct placement of the gas analyzer:

  1. From ovens and gas burners, a distance of 1 m must be observed;
  2. Do not install the device in places where condensation, ash, dust and grease are abundant;
  3. It is not recommended to install near ventilation and open windows;
  4. Do not place the gas analyzer near combustible materials, paint;
  5. If the chimney is not insulated, then it is better not to install a measuring device nearby.

Each type of measurement has its own optimum clamping height. Each gas has its own places of accumulation. Some gases settle at the bottom, others rise up.

Combined sensors are installed at a height of 30 cm from the floor and 50 cm from the ceiling. Methane and propane sensors are mounted as follows: 50 cm from the ceiling and floor, respectively. For carbon monoxide analyzers, the optimal height is 1.8 m from the floor and 30 cm from the ceiling.

To install the gas analyzer on the wall, you do not even need to open the case. It is enough to fix the device on nails using a special hole. The next step is to install the valve. The cutter should only be installed by specialized organizations with the appropriate license. The analyzer is connected to the valve according to the scheme indicated in the passport.

Checking the performance of a household gas analyzer

Every year it is necessary to carry out a metrological check of the device. It is not recommended to carry out this event with your own hands. This may damage the instrument.

If you find a clear problem, contact the gas service yourself.

You can only monitor the external cleanliness of the gas trap yourself. The device is usually guaranteed for 2 years. But on average, the device can last 8 years.

Gas separator brands:

  • STG-1;
  • SZ-2;
  • SOU-1.

The above options refer to the domestic manufacturer. There are also imported models on the market. But when buying domestic appliances, it is easier to carry out repairs.

What is a gas alarm (video)

An autonomous gas trap is necessary not only in industrial facilities, but also in residential buildings. Convenient system control helps to determine the minimum leakage from gas boilers and other appliances. To install the device, you do not need to have special skills, you can do everything yourself.

It is hard to imagine modern life without the use of gas, and therefore without the equipment that runs on it. Gas is used for cooking, home heating and.

But all devices that use gas are potentially dangerous, their use requires strict adherence to certain rules. But with all this, we constantly hear about the latest incidents related to gas explosions.

Usually the cause of all these accidents and accidents is a gas leak. And even for conscientious consumers who follow all the rules for using gas appliances, misfortune can happen as the equipment gets old and periodically fails.

To prevent the serious consequences of a gas leak, gas detectors are used.

The main function of these devices is to control the level of combustible gases in the air. When a certain gas concentration is reached, the device turns on the sound and light notification of a leak, which allows people to respond in a timely manner and prevent an accident.

Gas alarms are widely used in industrial facilities where gas is used, in boiler rooms and in domestic premises. Therefore, depending on the purpose, the devices are divided into industrial and household.

Industrial ones have a more complex device and are complexes consisting of and.

Household devices are three times simpler and are designed to measure the concentration of gases often used in everyday life:

  • methane (CH4);
  • propane(C3H8)
  • carbon monoxide (CO), which is known as carbon monoxide.

Carbon monoxide is the most dangerous because it has no smell, no color, no taste, unlike propane and methane, which can be smelled. It combines with blood hemoglobin 300 times faster than oxygen and blocks its entry into the blood. acting on the brain and nervous system, carbon monoxide kills very quickly.

Even a small but chronic content of gas in the premises leads to chronic intoxication of the body, which is manifested by such signs as:

  • nausea;
  • headache;
  • decrease in mental abilities;
  • muscle weakness;
  • memory impairment.

All these problems can be avoided by using gas detectors that can notify you of a danger in time.

The main reasons for the increase in gas contamination of premises

Most often, such reasons are equipment malfunctions or incorrect operation of gas appliances, which include kitchen appliances. gas ovens, geysers for heating water.

The main faults are:

Regular preventive maintenance of gas equipment is the best prevention of accidents. But, nevertheless, the installation of a gas detector is always desirable.

According to the mode of operation, gas contamination detectors can be:

  • with constant mode;
  • with periodic.

Depending on the type of sensors used, they are divided into:

  • optical;
  • chemical;
  • thermochemical.

The gas detector may be:

  • monoblock, when the sensors are built into the signaling device;
  • control unit with remote sensors.

According to the amount of gases to be determined, the devices can be one- or two-component. The former can determine only one type of gas (carbon monoxide or methane), while the latter can determine both.

Devices with remote sensors can have one or two measurement channels. A sensor is connected to each of the channels, which determines any type of gas. Although it is possible to connect the same sensors to all channels.

The use of remote sensors makes it possible to control the level of gas contamination at a distance of up to 200 m.

If there are several sources of possible gas leakage, then it makes sense to connect several monoblock devices to one actuator capable of shutting off the gas.

Cases of devices from different manufacturers can have different sizes, shapes and colors.

Basic functions of the gas detector

These devices are multifunctional devices, and signaling devices from different manufacturers can be equipped with a different set of features. Therefore, when buying, you need to focus on the specific needs of your system.

The main functions inherent in almost all types of sensors:

  • sound and light warning of exceeding the level of gas contamination;
  • output relay through which you can connect such devices as an additional siren, exhaust fan, signal to the dispatcher console and some others;
  • the ability to connect electromagnetic, cutting off the gas supply;
  • outputs for connecting additional equipment from the sensor;
  • some devices have the ability to work from an autonomous power source.

Installing a household alarm

Most often, household appliances are powered by a 220 V mains.

You can install the device yourself, but you must take into account all the requirements for installation, regulated by the following regulatory documents:

  • Federal Law No. 384-FZ;
  • SNiP 42-01-2002;
  • SP 41-108-2004;
  • SP 62.13330.2011.

Installation is carried out in the following order:

  1. Choice of the place of installation of the signaling device and preparation of the project.
  2. After installing the device, the cables of the executive systems are connected to it.
  3. The equipment is being set up.
  4. System performance testing.

In case of any difficulties, it is better to contact the gas service.

The signaling device is mounted on the wall in the place where gas leakage is most likely (near the boiler, gas column or meter, near the gas stove). The horizontal distance from the gas appliance must not exceed 400 cm.

There are places where it is strictly forbidden to place a gas detector:

  • next to or near open windows;
  • next to non-insulated chimneys;
  • in places where grease, dust, steam or ash can get on the device;
  • not less than 100 cm away from gas ovens and burners;
  • where gasoline, thinner or paint is stored.

The mounting points of the sensors are also regulated depending on which gas the detector should detect:

  • carbon monoxide - not lower than at a height of 180 cm from the floor and not higher than 30 cm from the ceiling;
  • methane - not lower than 50 cm from the ceiling;
  • propane - no higher than 50 cm from the floor (if there are any recesses in the floor where gas can accumulate, an additional signaling device must be installed in them);
  • a combined sensor that detects both methane and carbon monoxide - at a distance of 30 - 50 cm from.

The installation height depends on the density of the gas. Propane is heavier than methane and carbon monoxide, so it accumulates close to the floor.

If you decide to install not only a gas alarm, but also a shut-off valve, you will have to contact a specialized company that has a license for such work.

Checking and maintenance of the signaling device

Metrological verification of the device is carried out annually. It is forbidden to check the performance of the sensors yourself. This can disable them.

If you yourself discovered a malfunction of the device, then you need to call the gas service.

The rest of the maintenance of the gas detector is mainly to remove dust from its housing.

The warranty period for the sensor is usually no more than 2 years, but the average service life is up to 8 years.

The following devices of Russian manufacturers are mainly represented on our market:

  • STG-1, STG-3, SOU-1 (SPO "Analitpribor");
  • SZ-2 ("SGK");
  • BUG, ECO (Gazotron-S).

There are also imported gas analyzers from Seitron, but experts advise purchasing domestic products, since their repair and replacement are much cheaper.

The cost of a domestic signaling device ranges from 1400 to 4000 rubles, depending on the number of its functions.

As you can see, the acquisition and installation of such a device is within the power of every family. As for its necessity, it is obvious. Such a small and inexpensive device can prevent terrible accidents associated with the death of people and the destruction of buildings.

It is almost impossible to imagine a normal comfortable life without gas equipment in the house. The use of gas appliances allows us to heat rooms, cook food, provide home hot water. And all these devices can be potentially dangerous - gas leakage is possible, which can cause a fire or poison people. To prevent these misfortunes, gas detectors are installed - devices for monitoring the level of combustible gases in the air. Devices notify of a leak with a sound and light signal, which can save lives, health, and property.

Types of gas detectors and their functions

Gas alarms are used in domestic premises, furnaces, boiler houses, and industrial facilities. Depending on their purpose, household and industrial are distinguished. The first set the degree of gas contamination and are triggered if the gas concentration exceeds set parameters. The latter have a more complex design and represent entire complexes of sensors and control panels for measuring and displaying the concentration of gases in the air. Household type gas detectors can monitor the concentration of carbon monoxide, propane and methane.

Multi-channel gas detector can be installed to detect methane and carbon monoxide

Instruments can detect the presence of several gases in the air, such as carbon monoxide and methane. Such models are well suited for installation in rooms where heating equipment. Devices may differ in the type of power supply. Most often, signaling devices are used for 220 V.

Gas detectors can be automatic and manual. Gas level measurements are based on different principles:

  • physical method of analysis;
  • physical method of analysis with physical reactions;
  • physical method of analysis with physico-chemical reactions.

In addition to giving a sound-light signal about the level of gas contamination exceeding the specified level, household alarms can also perform other functions:

  • ensure the operation of the solenoid shut-off valve that shuts off the gas supply;
  • the ability to connect a relay that controls an exhaust fan, an annunciator that sends a special signal to the dispatcher console, and other devices;
  • the ability to connect additional equipment;
  • autonomous power supplies;
  • self-diagnosis function that provides information about the status of the device and its elements.

The memory function of some models will be very useful in order to save the results of measurements.

Some types of alarms determine the level of several gases in the air. Such models are called combined.

Gas detector installation technology

Install household alarm gas can be done by hand. It is necessary to determine the location of the sensor, install it and supply power, and then connect optional equipment. detailed instructions for installation and connection diagram are indicated in the passport of a particular device. The location of the gas detector is determined in advance - even at the design stage of the gasification system.

Experts remind: when installing a gas detector, it is necessary to take into account all the requirements of regulatory documents. This issue is regulated by the relevant paragraphs of the following regulations:

  • Federal Law N 384-FZ;
  • SNiP 42-01-2002;
  • SP 62.13330.2011;
  • SP 41-108-2004.

If you have doubts about your own abilities, there is not enough knowledge to choose a place to place the sensor, it is better to invite gas workers.

When installing gas detectors, you must follow the instructions, building codes and regulations

The signaling device is placed in places where gas leakage is most likely - next to the boiler, geyser for hot water supply, counter, stove. Max Distance from the sensor to the gas equipment - 4 m. It is forbidden to place devices in such places:

  • near sources of open fire, gas burners, ovens; the distance must be at least 1 m;
  • near places that can become sources of fat droplets, dust particles, steam or ash;
  • near windows, uninsulated chimneys or ventilation;
  • near paint and varnish compositions, solvents, combustible and fuel materials.

When determining the installation height of the signaling device, it is necessary to take into account the type of device, since sensors that respond to different gases (CH4, C3H8, CO) determine the density of air and gas. Focus on the following distances:

  • for a sensor that detects CO (carbon monoxide) - 1.8 m above the floor, but not lower than 0.3 m to the ceiling;
  • C3H8 (propane) - maximum 0.5 m from the floor, and if there are any noticeable recesses, care must be taken to install an additional sensor;
  • CH4 (methane) - 0.5 m from the ceiling;
  • CH4 and CO (combined) - 0.3 m-0.5 m to the ceiling.

The mounting method may differ depending on the model, but, as a rule, household gas detectors are attached using dowels. Usually, special holes are provided in the housing for installing sensors. Before installation, be sure to carefully read the product passport.

The passport of each model indicates the temperatures at which the device can be operated. Long-term storage at low temperatures may affect the performance of the detector. To restore it, you need to leave the device in the room for 3-4 hours at room temperature. The operating manuals for some CO signaling devices describe the procedure for restoring the zero threshold. It usually takes several minutes.

Pay special attention temperature regime operation, in some cases it is necessary to keep the device at room temperature

Why are solenoid shut-off valves needed?

These are devices that allow you to quickly shut off the gas supply in the event of a gas alarm. Valves are mounted at the inlet of the gas pipeline. Devices may differ in diameter, power, type of valve itself. The last criterion is especially important.

There are normally open and normally closed valves. Normally open, they are also called pulsed, because the electrical signal enters the coil of such a valve only at the moment the device is triggered. The coil of a normally closed valve is energized at the moment of opening, and the cutoff occurs when the voltage disappears.

Domestic models are easier to maintain and repair than foreign counterparts

In everyday life, it is most rational to use a normally open valve powered by a 220 V network. In the event of power outages, the device does not work, which allows you to use gas appliances that do not depend on electricity without restrictions. When open, the valve does not require electricity to operate.

Like all devices, the normally open valve has some limitations in use. It is undesirable to install it together with a gas sensor that checks its outputs automatically every time the power is turned on. The device will fire at these moments. Therefore, even before buying a valve, you should carefully familiarize yourself with the features of its operation. Basic information is indicated in the documentation for the device.

Do-it-yourself installation and connection of the shut-off valve is not allowed. This type of work should be carried out only by specialized organizations that have the appropriate permits.

Proper maintenance of gas detectors

The household gas detector is easy to operate and does not require any special maintenance. The maintenance that should be provided is minimal and consists of regularly wiping the device to remove dust, dirt, cobwebs. It is important to ensure that dust does not accumulate and enter the sensor housing through the grille.

Signaling devices are checked every year. Independent verification using “grandmother's methods” is unacceptable, for example, by supplying a 100% gas mixture from a lighter or other device to the sensor. Such verifications sometimes end with the failure of the sensitive element of the sensor. It is necessary to provide metrological verification by specialists. The service is paid, and this should be taken into account in advance.

If a malfunction of the gas control system is detected, ensure good ventilation in the room and call the gas service. Before the arrival of a specialist, do not turn on electrical appliances or use open flames.

Experts recommend giving preference to gas detectors of domestic production, since if it is necessary to replace the device, they are cheaper than imported counterparts when buying and repairing. In addition, repairs are usually carried out faster.

A household gas alarm is a simple and inexpensive device that almost everyone can afford. There are practically no hassles with its maintenance, it is only necessary to check the device in a timely manner and wipe it from dust. This simple device could one day save your life and the lives of the people you care about. Ask yourself the question of whether it is worth installing a signaling device - and for sure the answer will be yes.

CHOOSE A HOUSEHOLD GAS DETECTOR.

We are increasingly thinking about the safety of our property and protecting our health, the question arises how to do this?

For automatic continuous monitoring of the presence of explosive and toxic gases in domestic and communal premises, it is necessary to install
HOUSEHOLD GAS DETECTOR.

There is currently a wide range of household gas alarms. Neither become popular. They can often be found in houses and apartments. For a nominal amount, you can purchase an excellent certified device that will continuously monitor the presence of dangerous and toxic gases in the room (such as natural gas (Methane CH4,) liquefied fuel gas (Propane C3H8) or carbon monoxide (Carbon monoxide, Carbon monoxide, CO). Installing a signaling device will eliminate the possibility of an explosion of accumulated combustible gases and further spread of flame, poisoning of people in the room with large concentrations of toxic gases due to leakage, depressurization of gas pipelines, attenuation of the burner flame, reverse draft, etc. Carbon monoxide control signaling device, as an additional , can be used as a fire gas detector to detect fires in the early stages of their occurrence.

What is the working principle?

The principle of operation of the device is based on the passage of air, by natural convection, through the sensitive elements built into the signaling device. In case of exceeding permissible concentrations of hazardous and toxic gases, above the thresholds, the signaling device gives an emergency sound signal, disconnects the equipment from the gas supply line, turns on the hoods, light signal displays, sirens, transmits an alarm signal via GSM communication channels, through an additional installed devices signal transmission. After the gas supply is stopped and its concentration in the air drops to normal, the sound signal will stop, auxiliary devices will turn off, and the indicator will return to the measurement mode. After eliminating the cause of the signaling device (leakage, burner damping, reverse draft, etc.), independently or by the gas service, depending on the malfunction, it will be necessary to restart the disconnected heating or heating equipment.

What are household gas alarms?

The designs of household gas detectors are usually standard. Sensing elements are built into the signaling device (monoblock version) or taken out outside (remote sensors). Devices are single-component or two-component, i.e. can simultaneously control the concentrations of natural and carbon monoxide in the air (two-component) or one of them (single-component). Signaling devices with remote gas sensors have one or two measurement channels. Each channel is connected to one of the necessary gas contamination control sensors, in which sensitive elements are built. For example, a sensor for monitoring the presence of natural gas (Methane CH4,) in the room air is connected to one measurement channel, and a carbon monoxide control sensor (Carbon monoxide, Carbon monoxide, CO) is connected to the second channel or the same sensors are installed on all channels. Signaling devices with remote sensors allow remote control of gas contamination of premises at distances up to 200 m. As an example, this can be basement, where the boiler room is installed, and there is a need for visual control of what is happening in the basement from the residential floor, in this case a two-channel gas detector of the SG-1 type will be convenient. Sometimes there are several possible sources of leaks or gas accumulations located at a distance from each other, where the rules require the installation of gas monitoring sensors. In these cases, it is advisable to install several monoblock signaling devices, such as SGB-1, and connect all devices to one gas valve or other actuator.
