One of the main assistants in everyday life and in production is natural gas. A modern person cannot imagine his life without him, but he can often cause many troubles. As a rule, cases of gas leakage at home and at work caused explosions and further fire. In order to avoid such tragic cases, you should buy and install a gas alarm in a timely manner.
Safety comes first
This device is a mechanism whose main task is to detect household gas and other combustible mixtures in air. As soon as the device detects a gas leak, it turns off its supply and informs people about the occurrence of a life-threatening situation. A gas detector is a device without which it can be dangerous to be in a room. It avoids the tragic consequences that arise as a result of a leak.
Affordable and reliable
The gas detector "Gas 1" is a device that allows you to inform about the presence of flammable gas vapors in the air in residential and industrial premises. If a dangerous situation is suspected, the device gives a number of sound and bright light signals in the fire system, which allows timely measures to be taken to prevent it.
Natural gas detectors have long been installed in industrial premises, and more recently they moved to residential buildings. This allows you to ensure security in your own home. Because of this, almost the entire range of devices in many companies that specialize in the manufacture of a device called a gas alarm has undergone significant changes. Its price has declined significantly in recent years, due to which such devices have become affordable for most people.
What else are signaling devices capable of?
Depending on the model you have chosen, the device will perform a certain set of functions. Many devices are equipped with a light indicator that allows you to notify in a visual way of an increased concentration of hazardous gas. Typically, the operation of the device is designed in such a way that the light alarm is accompanied by high-volume sound. A number of signaling devices boast the ability to connect a wide range of add-ons. For example, it may be an electromagnetic valve, which in an emergency will shut off the gas supply.
More expensive models have the ability to connect to autonomous exhaust systems, which, when an emergency occurs, turn on and allow you to clean the air in a short time. Signaling devices work from 220 V, a similar power supply is required for additional devices. This allows you to install a warning system in almost all rooms that are equipped with a network connection. This can be either a residential building or an apartment, or an industrial building.
Great opportunities
A flammable gas detector is a device that allows you to control the concentration of not just one gas in the air, but immediately a large range of explosive substances. Such devices are available in many specialized stores, including on the Internet. If your home is equipped with a natural gas heating system, methane or propane may leak. If heating and cooking takes place using an oven, then a situation may arise where the concentration of carbon monoxide in the air will be increased .
However, these points can be omitted if you choose a device that can capture several dangerous gases. This saves time and improves the security of your premises. It should be noted that most stores that specialize in the sale of fire safety devices also offer installation services. You should not neglect them, since these are technically complex devices, the installation and configuration of which should be done by professionals.
Not only to notify, but also to save!
An electromagnetic valve is a device that typically includes a gas alarm. A household appliance with this supplement is very useful, because its task is not only to warn people about a possible emergency, but also to take measures to solve it. If the signaling device has caught vapors of hazardous substances in the air, a valve immediately enters into operation, which automatically shuts off the gas supply to a given sector or to the entire room. Varying the installation location of the valve, you can choose where the gas will flow after shutoff.
The main differences between such devices are the diameter, maximum pressure and type of valve feed. In domestic conditions, valves are used, the diameter of which varies from 15 to 25 cm. For power, they require a 220 V outlet. The pressure that they withstand does not exceed 500 mbar.
Valves are of two types: pulse and normally closed. All of them are equipped with the possibility of manual activation, which allows you to limit the gas supply even during a complete blackout of the building.
How it works?
After the gas alarm has tripped, a short-time voltage is applied to the pulse valve, which is sufficient to shut off the gas supply. To maintain the valve open, no electricity is required, which is the main advantage of the device. Correct operation of a valve of the type normally closed is possible only with continuous supply of voltage. That is why in household use it is enough to install a pulse device, since its operation does not directly depend on the power source. This avoids the consequences of frequent power outages, which are expressed in the fact that when the voltage on the valve is absent, it automatically closes. In this case, you will be left without light and without gas.
Carbon monoxide is a particular hazard
The carbon monoxide detector is a device whose primary task is to continuously monitor the excess of the optimum amount of this substance in the surrounding air. This signaling device can be used both in residential premises and in domestic, administrative and public buildings. This is necessary if they have heating appliances or gas stoves. It is also advisable to use them in garages, mines, wells and where there is a possibility of accumulation of carbon monoxide vapor.
The standard set of the signaling device includes a power supply unit for connecting signaling devices, signaling units, the number of which is equal to the number of installation points of signaling devices, connection cables and a shut-off valve. The device monitors the concentration of carbon monoxide on two thresholds: the first is set at 200 mg / cu. m, and the second - in 100 mg / cubic meter. m. The warm-up time is around 3 minutes, while the device has a very quick reaction to air pollution. The temperature range is from 0 to 50 degrees Celsius. The detector emits an audio signal with a volume level of 80 dB and has a degree of protection IP42. The average life of the detector is 10 years, and the sensor is 5.
Features of functioning
During operation, the device monitors the level of carbon monoxide in the air. When the threshold value is exceeded, the alarm is turned on, and the status indicator lights up in bright red and gives a sound signal. If the gas concentration has fallen below the first threshold, then the alarm is completely turned off. If the dangerous level exceeds the second threshold, an alarm is activated: the indicator starts flashing red and is accompanied by a two-tone sound signal. The alarm automatically switches on the exhaust systems and closes the valves, if any.
Portable versions
The SGG gas detector is a portable device that allows you to control the concentration of flammable gas vapors in the air. The device performs continuous scanning of the concentration of gases in the air and, when the norm is exceeded, gives out sound and light signals. Fields of its application:
- enterprises specializing in the extraction and processing, as well as transportation and storage of natural gas, oil and oil products;
- industrial enterprises whose activities are connected with the production of varnishes and paints, as well as sewers, boiler houses and alcohol storage facilities;
- welding in the immediate vicinity of flammable cans or containers;
- river and sea ports, as well as ships and tankers;
- stations specializing in the production of hydrogen and oxygen in cylinders.
The device works as an individual type of gas analyzer. Sampling is carried out by diffusion method. The device operates according to the thermochemical principle. Its main advantage is mobility, which allows you to quickly determine the concentration of hazardous gases in almost any room without installing bulky equipment.
What is the result?
The gas leak detector is available on the market in several different versions, and all of them meet the requirements of the state standard (GOST). The device is equipped with a memory, which stores all the data for the last month. Their recording occurs at a certain interval, as a rule, this is one minute. Using a USB interface, a connection is made with a computer, to which the results are received, where they are analyzed. Buy it or not - everyone decides for himself. However, do not forget that your security and your loved ones may be at stake.
