A fire extinguishing system is a special engineering system used to detect, contain, and prevent the spread of fire in various locations.
The main purpose of this system is to prevent financial and human damage due to fire and to create safety conditions for people present in the desired location. These systems start extinguishing the fire after detecting fire alarm systems, which include a set of different equipment and technologies. In general, fire alarm systems include:
Smoke detectors/heat detectors/sirens and bells/control panels and…
Through the combination of various components of this system, fire detection provides a rapid response to it to reduce physical and financial losses. There are different types of fire extinguishing systems that are selected depending on the type and size of the location and specific needs. Fire extinguishing systems come in two forms: manual and automatic. In the rest of this article, we will examine the different types of fire extinguishing systems and their application and performance.
An automatic fire extinguishing system is a safety system that automatically detects and suppresses fires in various environments without the need for human intervention.
These systems are designed to prevent the spread of fire, protect life and property, and reduce environmental damage.
Automatic fire extinguishing systems are designed and installed based on the type and size of the location, specific needs and type of activity, etc. These systems ensure that in the event of a fire, predetermined actions are taken and people’s safety is maintained. We will examine several types of these automatic fire extinguishing systems below.
Halon gas automatic fire extinguishing system is a type of fire extinguishing system that uses halon gas as the extinguishing agent. Halon is an inert gas that decomposes with oxygen in the air when exposed to heat and flame, but at the same time can extinguish the fire.
Features of the Halon fire extinguishing system include the following:
The automatic water sprinkler fire extinguishing system is one of the most common and effective fire extinguishing systems used in various locations.
This system consists of water-filled pipes and sprinkler heads, and is automatically activated to discharge water onto the fire-stricken areas. The features of the automatic water sprinkler fire extinguishing system are:
Sprinkler systems usually include thermal sensors that are sensitive to changes in temperature and heat in a location. When the temperature rises above a certain level, the sensors send a signal to the system.
Pipes containing water are installed along the length and width of the site, and as the water is released, it flows to the sprinklers and from there to the area under fire.
Sprinklers are installed as actuators on pipes and, when activated by sensors, deliver water in the form of small flame spread or dispersion at the fire site.
Water is sprayed directly onto the flames through sprinklers, extinguishing the fire.
Sprinklers quickly control the fire and prevent it from spreading to other areas.
In addition to extinguishing the fire, this system also helps to clear the environment of smoke and toxic gases caused by the fire.
Automatic water sprinkler fire extinguishing systems are highly recommended as a vital way to combat fires in various places such as residential, commercial, industrial and public buildings. This system reduces financial and human losses.
An automatic powder or aerosol fire extinguishing system is a type of fire extinguishing system that uses powder or aerosol as a fire extinguishing agent. These systems are used to extinguish fires and control their spread in different locations and also disperse fine solid particles (less than 10 micrometers in diameter) in the form of a fog onto the fire and extinguish the fire. The old generation aerosol uses powder particles and the new generation aerosol uses gas to extinguish the fire.
The features of an automatic powder or aerosol fire extinguishing system include:
Automatic powder or aerosol fire extinguishing systems are typically used in locations where water fire extinguishing systems are not suitable, such as fuel tanks, chemical storage facilities, server rooms, and other sensitive electronic locations.
Automatic powder or aerosol fire extinguishing systems are mainly used in places where powder or aerosol suspensions are suitable and effective. These systems are very effective in controlling and extinguishing fires and are often used as a suitable alternative to water fire extinguishing systems in certain places.
Foam automatic fire extinguishing system is a type of fire extinguishing system that uses foam absorbent as the extinguishing agent. These systems are used to control and extinguish fires in various locations.
Automatic foam fire extinguishing system is used as an effective method for controlling liquid fires in industrial locations. This system automatically controls and extinguishes fires by creating foam. Among the advantages of this system is that in some cases, it has lower consumption than water fire extinguishing systems and does not damage electronic devices and equipment.
The F&G fire extinguishing system or Fire and Gas (F&G) system is of obvious importance as a permanent guard in environments exposed to fire and gas hazards. It integrates advanced technologies for the detection and management of fires and gas leaks, ensuring the safety of industries such as petrochemicals, refineries and manufacturing. Using a multifaceted network of sensors, alarms and automatic responses, it proactively deals with various hazards and ensures the uninterrupted operation of industrial facilities, while prioritizing the safety of personnel.
Fire suppression systems are critical for server rooms or data centers because these rooms typically contain sensitive and important electronic equipment that is at risk of fire.
Water and electronics don’t mix. Because a data center is filled with computers, hard drives, disks, and other sensitive equipment, it also requires something more than just regular sprinklers to protect your assets from potential fires.
In the past, Halon was a primary fire suppression option instead of water, but it was phased out when it was discovered that halon damage ozone. Existing halon fire suppression systems are permitted to be used, but new installations must use an alternative extinguishing agent.
The best option for installing a fire suppression system is scavenging agents. This is a gas system that works by either reducing the oxygen of flames or by heat. The main advantage of scavenging agents is that they leave no residue, allowing them to suppress flames without damaging your IT equipment.
There are several cleaning agents suitable for use in data centers. Generally, fire extinguishing in server rooms is done through FM200 and Aerosol fire extinguishing systems, with Aerosol being of particular importance compared to FM200 fire extinguishing systems, and inert gas fire extinguishing systems, Co2 fire extinguishing systems, and Novec1230 fire extinguishing systems can also be used.
Each of these systems has its own advantages and limitations, and the choice depends on the type and specificity of the data center and the equipment available. In server rooms and data centers, the safety of electronic equipment is very important, and must be carefully planned and installed to minimize the risk of fire and prevent destructive effects.
Designing a fire extinguishing system in a building is an important and vital process to keep people safe in the event of a fire. Below we will review the general steps for designing a fire extinguishing system in a building:
First, you need to determine the specific needs of the building. This includes the type and size of the building, its uses, existing equipment, the need to protect life and property, and the need to protect electronic equipment.
To design a fire suppression system, you must be familiar with fire-related standards and regulations. This includes national and international standards related to fire suppression and building safety. The Engineering System Organization has developed a code of conduct for fire suppression in buildings. Some of its points are listed in the table below.
Conducting a fire analysis typically involves assessing the fire hazards in a building and determining the likelihood and impact of different fires on the building. This analysis can help determine the need for fire suppression systems and their appropriate location. It must be decided which type of fire suppression system (e.g. sprinkler, gas, foam, dry, aerosol, etc.) is appropriate.
This stage involves the detailed design of the fire extinguishing system, including the location and number of sensors, piping, sprinklers or other equipment. After design, the fire extinguishing system must be installed and commissioned by specialist teams.
After installation, people working in the building should receive the necessary training on using the fire extinguishing system.
Also, the system must be tested and verified. To keep the fire extinguishing system functioning properly, you need regular maintenance and periodic inspections.

Fires can be divided into several categories based on their origin, type of fuel, and other classification methods. These classifications help to better understand the nature of fires and the types of fire suppression systems, including the extinguishing agents used. Common fire classifications include:
Each fire can have unique characteristics and require different extinguishing methods and extinguishing agents. Therefore, correctly classifying fires helps in selecting appropriate extinguishing methods and creating effective safety programs.
Class A fires, also known as dry fires, refer to fires that involve the burning of solid materials such as wood, paper, cloth, linen, trash, plastic, and similar organic materials. These types of fires are classified as Class A fires based on the type of combustible material burning. Dry fire extinguishers can be used to fight Class A fires.
Class B fires refer to fires caused by the burning of flammable liquids such as gasoline, oils, diesel, plastic melts, other oils, and similar chemical liquids. To combat Class B fires, dry fire extinguishing agents and special neutralizing agents are used as one of the primary means of extinguishing the fire.
Class C fires refer to fires caused by electrical equipment such as electrical cables, electrical and electronic equipment, electrical machinery and similar equipment. Class C fires are usually fought with gaseous extinguishing agents or special fire extinguishing agents. These agents are used as a means of extinguishing fires and have oxygen-neutralizing effects.
Class D fires refer to fires caused by the burning of flammable metals such as magnesium, sodium, potassium, and similar flammable metals. These types of fires require special neutralizing fire extinguishing agents to combat them.
The price of fire suppression systems varies greatly and is affected by a variety of factors, including the type of system, the size and specifications of the system, the type of extinguishing agent, and the installation and maintenance required. The geography of the installation location can also affect the price. Some of the factors that affect the price of these systems include: type of fire suppression system, type of extinguishing agent, and … .

For example, in factories and small manufacturing units, homes, etc., two-mode plastic and metal nozzles can be used. However, if you can choose all-steel or metal nozzles, it is better because they are more resistant.
The best option for extinguishing a server room fire is to use clean agent fire extinguishing systems such as FM200 and NOVEC1230 because they leave no residue.
CO2 fire extinguishing was developed for use in electrical equipment, suppressing fires by displacing oxygen. In fact, in this system, carbon dioxide (CO2) gas is usually used in the compositions inside fire extinguishers.
Fire suppression system servicing is very important. These systems are pressurized tanks that can explode due to corrosion or damage, and research has shown that in some cases they can cause serious injury and even death. Maintenance methods include visual inspection by the user and servicing and maintenance by reputable construction companies.
