Automatic fire extinguishing systems: purpose and main characteristics

Modern ASPT independently monitor the condition of the controlled zone. If a fire or the slightest threat of a fire hazardous situation is detected, APT, through numerous sensors, directs information to the control remote control and automatically extinguishes in the shortest period of time.

Automatic fire extinguishing systems (ASPT) have become widespread due to their inherent multi -functionality and uniqueness. Such complex systems are designed to ensure fire safety in organizations and industries.

ASPT is a multifunctional system consisting of a whole complex of algorithms: monitoring the condition of the installed sensors, a system for tracking the temperature threshold, turning on light alarms and sound alerts, automatic launch of a fire extinguishing system.

The main advantage of the development and use of APPT is the timely detection of the fire and the ability to independently eliminate the threat of its occurrence after pressing the fire alarm button. In this case, water, foam solutions, powder compounds and various gases (argon, nitrogen and inert gases) act as a fire extinguishing matter.

The installation of an automatic fire extinguishing system provides for mandatory preliminary familiarization with the main types of automatic fire extinguishing installations, their characteristic features, advantages and obvious disadvantages, as well as the principles of their functioning at a particular object. A thorough study of all information will become the basis for the correct choice of automatic installation, which will completely suit you.

Classification of automatic fire extinguishing systems

It is customary to distinguish between the following automatic fire extinguishing installations:

1. automatic water fire extinguishing system;
2. automatic gas fire extinguishing system;
3. powder fire extinguishing systems.

Automatic water fire extinguishing system

Today, the elimination of fires by the automatic system of water fire extinguishing is considered the most effective and safe method of combating fire.

90% of fires are eliminated due to such attitudes. Nevertheless, water fire extinguishing systems have some shortcomings: their operation is associated with high costs for the purchase of water in the volume of sufficient to extinguish the fire. The water supply should be stored in special tanks and drainage structures, pumping stations. Other capital engineering structures are often required.

A significant drawback of the automatic system of water fire extinguishing is the possibility of damage to material values \u200b\u200band a room or building.

All these shortcomings can be overcome using a special technology for eliminating fires fine -polled water, providing for a more rational water consumption and artificial reduction in the size of water drops. As a rule, in the process of extinguishing fires, only 30% of the total water consumption is used directly to eliminate the fire, the rest of the volume is consumed in vain.

In the process of extinguishing a fire, water fog with characteristic high penetrating and cooling abilities is formed with thin -posed water. Thanks to this technology, the elimination of the fire is carried out with greater reliability with a rational water consumption.

Automatic gas fire extinguishing system

Automatic gas installations of fire extinguishing They are used to identify foci of fire, operational warning about the fire and its extinguishing with special fire extinguishing gas. The use of such automatic systems allows you to protect equipment from corrosion, and the consequences of the operation of such installations are eliminated by conventional ventilation of the room. Automatic gas fire extinguishing systems are resistant to high and low temperatures, and their installation is ideal in those rooms where electrical equipment is located under voltage.

A system of this type operates on the basis of a decrease in oxygen by entering a sufficient amount of non -combustible gas in the zone of fire. In this case, the liquidation method can be either local-volume or voluminous.

Powder fire extinguishing systems

In accordance with fire safety standards, all public and administrative and buildings, the premises of the warehouse and production type are subject to equipment automatic powder fire extinguishing systems.

The liquidation of the fire is carried out due to the operational supply to the fire zone of fine, non -toxic powder composition. Its low cost and ease of operation of the system in the absence of harm to the room and equipment are undeniable advantages of such installations. The consequences of using powder fire extinguishing systems are eliminated by cleaning the room. The only drawback is the limited shelf life.

Design and installation of automatic fire extinguishing systems

Installation of an automatic fire extinguishing system In accordance with the requirements of GOST, it is a comprehensive system of special technical means for the operational localization of fires with fire extinguishing agents. Objectively, such attitudes include tanks and devices with fire extinguishing agents, a pipeline and atomitors, control and control systems.

The installation of the fire extinguishing system is the most costly stage of all measures to ensure reliable fire protection of the object and is carried out only after designing automatic fire extinguishing and fire alarm systems.

The design of automatic fire extinguishing systems pursues a number of goals:

1. automatic fire extinguishing installations, if possible, should be modular, connected to individual control units to increase the performance of the system as a whole;
2. the functionality of the entire system, and individual branches are ensured due to the presence of a wireless Wi-Fi connection of each installation with the control unit, which completely eliminates the possibility of refusing fire extinguishing in the event of a slight-flow line break under the influence of high temperatures or open fire;
3. fire extinguishing installations and automatic fire alarm systems should have several independent autonomous power sources;
4. the zones of the most likely fires should be equipped with automatic powder or aerosol plants.

In general, the design of automatic fire extinguishing systems is determined by the area of \u200b\u200ba particular object, the nature and condition of the materials located on the territory of the facility, the presence of maintenance personnel and the category of the facility for explosive and fire hazard.

Service service of the automatic fire extinguishing systemit is a set of works carried out with established frequency and ensure trouble -free and long -term communications and reducing energy expenses.
