Gas alarm and its characteristics

One of the main assistants in everyday life and in production is natural gas. Modern man can not imagine his life without him, but he can often cause many troubles. As a rule, cases of gas leakage at home and at work were the cause of explosions and further fire. In order to avoid such tragic cases, it is necessary to buy and install a gas detector in a timely manner.

Safety first

This device is a mechanism whose main task is to detect domestic gas and other combustible mixtures in the air. Once 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 result from a leak.

Available and reliable

The gas detector "Gas 1" is a device that allows you to inform about the presence in the air of fumes of combustible gases in residential and industrial premises. If there is a suspicion of a dangerous situation, the device supplies a number of audible and bright light signals in the fire system, which allows taking timely measures to prevent it.

Signals of natural gas have long been installed in production facilities, and recently moved to residential areas. This allows you to ensure safety in your own home. Because of this, a significant number of devices have undergone significant changes in many companies that specialize in the production of a device called a gas detector. Its price has declined significantly in recent years, due to what such devices have become available to most people.

What else are signaling devices capable of?

Depending on the model you select, the device will perform a certain set of functions. Many devices are equipped with a light indicator, which allows you to notify in a visual way about the increased concentration of dangerous gas. Usually the operation of the device is constructed in such a way that the light signal is accompanied by a sound of high volume. A number of signaling devices can boast the possibility of connecting a large range of add-ons. For example, it can be an electromagnetic valve, which in an emergency situation will block the flow of gas.

More expensive models have the ability to connect to autonomous exhaust systems, which in the event of a sudden situation turn on and allow a short time to clean the air. Alarms operate from 220 V, the same power is required for additional devices. This allows you to set up an alarm system in almost all rooms that are equipped with a network connection. It can be either a dwelling house 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 on sale in many specialized stores, including the Internet. If your house is equipped with a natural gas heating system, then methane or propane may leak. If, on the other hand, heating and cooking takes place by means of an oven, then a situation may arise where the concentration of carbon monoxide is increased in the air .

However, these moments can be omitted if you select a device that can catch several dangerous gases. This saves time and increases the security of your premises. It should be noted that most shops that specialize in the sale of fire safety devices offer services for their installation. It is not worth neglecting them, since these are technically complex devices, which should be assembled and tuned by professionals.

Not only to notify, but also to save!

An electromagnetic valve is a device that, as a rule, 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 situation, but also to take measures to solve it. If the warning device caught a couple of dangerous substances in the air, then immediately comes into play a valve that automatically cuts off the gas supply to a given sector or to the entire room. By varying the location of the valve, you can choose where the gas will flow after the shutdown.

The main differences between such devices are the diameter, maximum pressure and type of power supply of the valve. In household conditions, valves with a diameter varying from 15 to 25 cm are used. For power supply they need a socket with a voltage of 220 V. The pressure they withstand does not exceed 500 mbar.

Valves are of two types: impulse and normally closed. All of them are equipped with the possibility of manual activation, which makes it possible to limit the supply of gas even during the complete de-energization of the building.

How it works?

After the gas warning light has been activated, a short-time voltage is applied to the impulse-type valve, which is sufficient to shut off the gas supply. To support the valve in the open state, no electricity is required, which is the main advantage of the device. Correct operation of the valve, which is of the normally closed type, is possible only with continuous supply of voltage. That's 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 there is no voltage on the valve, it automatically closes. In this case, you will remain without light, and without gas.

A particular danger is carbon monoxide

The carbon monoxide alarm is a device whose primary task is to continuously monitor the excess of the optimum amount of this substance in the ambient air. This alarm can be used both in living quarters, and in domestic, administrative and public buildings. This is necessary if they have heating devices 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 unit intended for connecting alarms, signaling units, the number of which is equal to the number of signaling points, connection cables and a check valve. The device monitors the concentration of carbon monoxide in two thresholds: the first is set at 200 mg / cc. M, and the second - in 100 mg / cu. M. The warm-up time is about 3 minutes, while the device has a very fast response to air pollution. The operating temperature range is from 0 to 50 degrees Celsius. The signaling device emits a sound signal with a volume level of 80 dB and has a degree of protection IP42. The average service life of the signaling device is 10 years, and the sensor - 5.

Features of functioning

During operation, the device monitors the level of carbon monoxide in the air. When the threshold is exceeded, the alarm is activated and the status indicator glows bright red and beeps. If the gas concentration falls below the first threshold, the alarm is completely turned off. If the dangerous level exceeds the second threshold, an alarm is triggered: the indicator starts flashing red and is accompanied by a two-tone beep. The alarm automatically switches on the exhaust systems and closes the valves, if any.

Portable versions

The gas detector CHS is a portable device that allows you to monitor the concentration of fumes of flammable gases in the air. The device performs a continuous scan of the concentration of gases in the air and, when the norm is exceeded, produces a sound and light signals. Areas of 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 associated with the production of varnishes and paints, as well as sewerage, boiler houses and warehouses for storing alcohols;
• Welding in the immediate vicinity of flammable cans or containers;
• River and sea ports, as well as vessels 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. The device operates according to the thermochemical principle. Its main advantage is mobility, which makes it possible to determine the concentration of dangerous gases in virtually any room in a short time without installing bulky equipment.

What in the end?

The gas leak detector is presented on the market in several different modifications, and all of them meet the requirements of the state standard (GOST). The device is equipped with a memory, in which all the data for the last month are saved. Their recording occurs at a certain interval, as a rule, this is one minute. With the help of the USB-interface, a connection is made to the computer to which the results are received, where they are analyzed. Buy it or not - each for himself decides for himself. However, do not forget that at stake can be your safety and your loved ones.
