Automatic fire extinguishing systems. Installation, prices, reviews

Providing the highest security of a person and property is an important task that is assigned to those who are responsible for the premises.

The need for fire extinguishing systems

There are cases when it is simply impossible to protect yourself from all kinds of dangers, but there is a threat that can be prevented. In this case it is a fire. Automatic fire extinguishing systems, installation and design of which are very important moments, must be installed in accordance with certain documentation, which is the most important factor when achieving the highest level of safety.

Design Features

Initially, you need to determine the type of construction. It is from this stage that system design begins. The building can be residential, not intended for living, being under tension, and also intended for storage of valuable things, equipment and other things.

Automatic fire extinguishing systems, installation of which is most often performed exclusively by specialists, assumes at the design stage the choice of equipment - it can be powder, water or other, which will depend on the type of premises. For example, if it is necessary to protect the warehouse from the occurrence of fire, where there is a large amount of metal, then it is best to use a powder system for this. If the design is made for the library, it is recommended to consider the gas installation, since water and foam can damage the documents.

Important factors that are taken into account in the design

Automatic fire extinguishing systems, the installation of which must be carried out according to certain rules, provide for the determination of the optimum temperature regime at the design stage . This factor is connected with the previous point, that is, with what system it is decided to apply. Thus, if the temperature does not fall below the zero mark, it is possible to use only spray, foam or water sprinklers. If the temperature inside the building can be below zero, it is better to use a powder or gas flame extinguishing method.

Spinker systems and their design

If you are interested in automatic fire extinguishing systems, sprinkler and deluge systems can be called one of the most common. The first suggest the presence of water pipes. The system is constantly filled with a fire extinguishing compound. It has this name for the reason that it is equipped with sprinklers, which are special nozzles. Among them, one can distinguish a low-melting nozzle, which is exposed during ignition and is responsible for the supply of a fire-extinguishing substance in the place of ignition. This process will not depend on whether there are living beings in the room. The installation of such a system involves the installation of a network of pipes that have splicers. Installation is carried out under the floors of premises. A large area is divided into separate sections, each of which is served by its signal. In the process of installing automatic fire extinguishing control systems, this protection is often used because it has many advantages, among them one can single out the simplicity of the equipment.

Scope of use

Design, as a rule, is carried out for sports complexes, offices and apartment buildings. In this case, the height of the room should not be more than 20 meters. As an exception, the case when the installation is intended to protect the structural elements is used. When creating a project, some points are taken into account, namely the determination of the diameter of the pipeline, which must comply with existing regulations. In determining this parameter, there is a need to take into account that a certain amount of water must be delivered to the sprinklers at a critical time, which will be used to extinguish the flame. The shape of the jet and the area to be treated are selected.

Powder systems and their design

If you selected automatic fire extinguishing systems, installation, prices should be of interest. Information about this is provided in the article.

To eliminate the open flame, a special powder composition can be used. Such a system has its advantages, among them it is possible to highlight the ecological compatibility, the universality of use, and also a sufficiently rapid suppression of the flame. This approach is used to protect electrical installations and paint chambers, for engineering facilities and other facilities that do not presume the possibility of water quenching. In the process of designing this system it is important to determine the number of modules, as well as to make a calculation, taking into account the probability of uneven distribution of the powder. Among other things, professionals must properly distribute the modules.

Gas systems and their design

We continue to consider fire extinguishing systems (types, arrangement of this equipment are described in the article). Among other things, it is possible to distinguish gas installations, which are used in the case when there is no possibility of using other methods of extinguishing. As an example, there are museum premises. The design involves paying special attention to the calculations. Among the gas fire extinguishing systems, there are centralized and modular ones. The final choice will depend on the number of rooms that need protection, from the area and the type of the main building.

Common Errors

It is important to take into account that mistakes are often made when designing the described systems, namely, the NPB 88-2001 manual is used, which does not have a calculation procedure and corresponding programs. As a result, the diameters of the pipelines are too large or small. In no case should we neglect the weight of the extinguishing agent. Thus, with the use of Hladon-23, there is no mass control, despite the fact that this substance is a liquefied gas.

Features of the installation

Automatic fire extinguishing systems, which are installed after the approval of the project, must be installed by specialists. This is due to the fact that the safety of a person in the event of a fire will depend on this stage. The installation works provide for several types of manipulation, including tap water, as well as electrical work, welding, programming and so on.

It is important to carry out all calculations, because several types of elements must be assembled, among them those that are capable of detecting signs of a flame. As a rule, this is a whole set of sensors. It is impossible not to mention the elements that inform about the occurrence of extraordinary situations. The system must have devices storing and dropping quenching matter. These are reservoirs, pipelines and so on.

Installation of an automatic fire-extinguishing system, the cost of which will be mentioned below, provides for the installation of fire detectors, which are located on the ceiling. They should react to threats like smoke or open fire. The sensors are connected to the control panel.

Tanks

Among other things, it is important to mount tanks that will be filled with quenching agent. At the next stage, a pipeline system is installed, which is necessary for feeding the extinguishing agent with the atomizer. For more efficient operation of the system, it is necessary to connect the equipment that is responsible for smoke removal. This includes sounders. Among other things, additional elements must be connected, which guarantee protection from other threats, such as: burglar alarm.

Reviews of the water fire extinguishing system

The installation of an automatic fire-extinguishing system, the cost of which can start from 15,000 rubles, assumes, according to users, the presence of a pumping station, control units, sprinklers, water tanks, and a pipeline system. Owners of private houses and warehouses who decided to take advantage of fire protection in the form of a water system, note that the pumping station should be located in a separate room, but you can also use a separate building for this.

Anyway, the place is isolated by fire barriers, floors, fire resistance limit of which should be 45. Consumers note that they were given the task of providing the internal temperature of this room in the range from 5 to 35 degrees. Among other things, the humidity level should not exceed 80%. This is true for 25 degrees Celsius.

It is especially important to check emergency and working lights, as well as telephone communication. As consumers emphasize, control units are located at the pumping station. It is important that these parts of the system are freely accessible.

As for sprinklers, when working with an object that is distinguished by protruding elements of the ceiling or overlapping beams, these components need to be mounted between the above-mentioned protruding objects, this will ensure a more uniform coverage of the area at the time of extinguishment.

In the presence of a suspended ceiling in a niche, it is possible to make a hidden installation of sprinklers. Automatic fire extinguishing systems, whose history began several decades ago, suggest the presence of a water reservoir. It must contain the calculated amount of fluid necessary for extinguishing. It is best to install additional equipment, which will be responsible for blocking the flow of water for other needs. Among other things, as customers and users of these systems note, there is a need to install a device that will replenish the tank during extinguishing.

The described system of automatic fire extinguishing should provide for the presence of pipelines. This system can not be attached to the fire fighting systems of a sanitary or production plan, but it is possible to combine with a domestic drinking or production system.

Opinion of users on the installation of foam fire extinguishing

The economic justification for installing an automatic fire extinguishing system, an example of which will be described below, is explained by the need to protect oil, chemical plants, and power plants.

To extinguish the flame when using this system, several dispensers must be mounted. At the time of fluid supply, they are able to regulate the supply due to the difference in pressure at the inlet and outlet. The foam solution is obtained by the volumetric method, which includes the preparation of a mixture of a foaming agent in a container. According to people who observed the result of the work of this system, the foam solution is able to form a film on the surface that blocks the flow of air to the source of ignition.

In order not to repair the automatic fire extinguishing system, which may necessitate the operation, it is necessary to entrust the design and installation to specialists. Pipelines of the above described system can be filled with a filler, dry-tube or circulation method. The second option assumes a good filling up to the starting and closing devices.

Reviews of a fine-grained system

According to users, these fire extinguishing systems are the most economically profitable, this is due to the fact that they do not require the installation of pumping stations, reservoirs and treatment plants. Among other things, there is no need to build pipelines.

Owners of production facilities emphasize that this approach allows you to save a significant amount of money.
