This European standard defines the requirements and provides guidelines for design, installation and maintenance. stationary systems sprinkler type fire extinguishing industrial buildings and installations and defines the specific requirements for systems, the disappearance of the sprinkler type is an integral part of personal protective measures. The requirements and recommendations of this European standard also apply to any addition, expansion or other modification of a sprinkler type fire extinguishing system and do not apply to water spray or flood spray installations.
Modern water fire extinguishing systems are complex engineering structures that require regular inspection and maintenance. Maintaining a water-based fire suppression system is a necessary procedure to help keep the entire system in working order and to prevent the occurrence of problems that could affect the efficiency of its operation in the future.
This standard covers hazard classification, installation of water sources, components used, installation and testing of the system, maintenance and expansion of existing systems, and specifies the structural details of buildings that are necessary for the satisfactory operation of sprinkler-type fire extinguishing systems that comply with the European standard. This European Standard does not cover water supplies other than sprinkler systems. Its requirements can be used as a guide for other fixed fire-extinguishing installations, provided that the requirements specific to these other fire-extinguishing systems are taken into account.

Choosing a specialist
In the event of a malfunction, our specialists will promptly eliminate the problem by performing Maintenance automatic water fire extinguishing systems.
This European Standard is intended for those responsible for purchasing, designing, installing, testing, inspecting, approving, using and maintaining automatic systems fire sprinklers and will assist them in getting a rated job throughout their lives. This European Standard only applies to stationary fire-fighting installations sprinkler type installed in buildings and other areas on the farm land. Though general principles may apply to other uses, other considerations should be considered for those other uses.
Standard service maintenance of a water fire extinguishing system includes about 20 manipulations.
During scheduled inspection its operability, specialists carry out a whole range of test activities, from an external examination of the main units to flushing of pipelines, tests for fluid loss and complex testing of the entire system as a whole.
Requirements do not apply to automatic sprinkler-type sprinkler systems installed on boats, aircraft, mobile vehicles and fire trucks or underground fire extinguishing systems in the mining industry. Differences in the design of sprinkler systems can be resolved if such deviations have been demonstrated to provide a level of protection at least equivalent to this European Standard, for example by testing.
The sprinkler system belongs to the family of automatic sprinkler systems. This type is usually required in case of protection large areas... As with all fire extinguishing systems, heat is generated by the flame, the system is activated, and the fire is faked by distributing a jet of water. The automatic shutdown system consists of a network of pipelines and water supply. The nozzles dispensing nozzles sealed with a thermosensitive ampoule are located at an appropriate distance. In the event of a fire, the heat generated by the flame causes destruction of the thermosensitive element, thereby activating the atomizers and thus water flooding.
Equipment selection
The most optimal and demanded is the water automatic fire extinguishing... It is subdivided into two types: deluge and sprinkler.
The regularity of servicing water fire extinguishing affects not only its reliability, but also its service life. Timely checks extend the life of the system to 25 years. In case of neglect service, the service life of the system can be cut in half. In addition, fixing minor issues is significantly cheaper than overhaul and even more so the replacement of the entire system.
There are several types of sprinkler systems. The term "wet" refers to the presence of pressurized water within the piping system. The advantage of this system is, undoubtedly, the speed of operation and the quick recovery time of the installation after a reset, and the limit is possible risk freezing water inside water supply network... The most common are wet sprinkler systems.
Unlike the previous one, the water network contains pressurized air instead of water. In the event of a fire, pressurized air exits the nozzles, thereby changing the pressure within the pipeline network, thereby activating a control valve that allows water to enter the plant. This solution is suitable for installations in chilled or uncooled environments where wet systems can have frost problems. The disadvantage of this system is the time it takes to activate and restart the system.
Our guarantees
A mandatory requirement of the current regulations is the periodic maintenance and service of the system in order to prevent and prevent malfunctions before activating the fire extinguishing system.
It is advisable that the maintenance of the water extinguishing system be carried out by the same company that installed the equipment. The frequency of inspections is set in accordance with the documentation attached to the equipment and depends on the complexity of the system. Objects, through which a large flow of visitors passes, are checked at least once a month. In premises that are not intended for mass visits, inspections are carried out at least once a quarter.
A feature of this system automatic shutdown is the presence of nozzles that always open. The pipes are thus empty: neither under pressure, nor in water, nor in air. The system without thermosensitive elements is connected to the smoke or heat detection system, which triggers the start of the “flood” valve.
Sprinkler preloading combines the benefits of wet and dry systems by supporting a smoke or heat detection system. Fire detection by the installation allows pumping unit start in advance, accelerating the discharge of water, but the effective activation of the shutdown occurs, however, after the rupture of the heat-sensitive lamp. Dual detection allows one side to reduce water discharge due to false alarms and other reduced water flow timings.

The main advantages of the systems under discussion are the timely detection of a hazardous situation, as well as the ability to independently eliminate the threat of a fire source after pressing only the fire alarm button. Various gases such as nitrogen or argon, powder formulations, foam solutions and, of course, ordinary water can act as fire extinguishing agents.
it different shapes legal entities... Usually the landlord became a housing cooperative that was founded by tenants. For housing cooperatives that pay the purchase price for a home to the original owner, then often members demand the transfer of apartments to personal ownership, which is associated with the emergence of associations of unit owners.
Public Sector Housing Management

As of today, it is customary to distinguish between three main types of fire extinguishing systems. These are complexes that use water, specialized gases or powder mixtures. Will take a closer look at each of them.
Water fire extinguishing
Nowadays, the elimination of fires in buildings using a water fire extinguishing complex is the safest and most effective method. About 90 percent of all fires are extinguished thanks to just such installations. At the same time, these systems also have certain disadvantages. Their operation always implies high costs for the purchase of water necessary to extinguish a fire. It is customary to store water in specialized drainage facilities, reservoirs and pumping stations... As a rule, it is required to erect special capital engineering structures... The disadvantages of extinguishing with water also include a considerable likelihood of causing significant damage to the building, premises or material values.
Technical management of buildings and centers
We provide our clients with all the administrative and technical activities necessary to ensure a smooth operation. The subject of activity is the operation and maintenance of the building of the administrative complex, shopping center, warehouse complex or industrial premises... For our clients, we provide professional building technical services, regular inspections and inspections. We carry out periodic inspections of specialized technical devices based on the requirements of Czech legislation, such as revision of power distribution systems and appliances, emergency lighting, gas distribution systems and appliances, conduits, chimneys, fire extinguishers, pressure vessels, lifting equipment.
To some extent, the disadvantages can be overcome by using specific technologies. This is about water mist, providing for a fairly rational consumption, as well as artificial reduction of water droplets. Indeed, according to existing statistics on the course of extinguishing a fire with the help of water installations, only 30 percent of the total consumption is used to extinguish the fire. Extinguishing water mist implies the formation of a water mist, characterized by high cooling and penetrating properties. The technology makes it possible to more reliably localize and eliminate fires with less water consumption.
During this activity, we can provide electrical, plumbing, heating, castle, construction, carpentry, painting and painting works. Repair and installation plumbing installations, floor coverings, interlocking pavers or plasterboard installations.
We provide optimization of the operating economy, maintenance, repair and revision of the following facilities. We provide a range of services related to administration, economy and, above all, service and maintenance of the managed object.
Gas fire extinguishing
Gas extinguishing mechanisms are also used to identify the source of fire, alert and extinguish with a specialized fire extinguishing gas. Such systems make it possible to protect various expensive equipment from possible corrosion. The consequences of the operation of the installations are easily eliminated by the most ordinary ventilation of the room. The discussed systems are characterized by increased resistance to low and high temperatures. They are almost ideal in rooms where DC voltage electrical equipment is located.
All spheres technical operation including preventive services, daily traffic monitoring system maintenance 24 hours service emergency, professional disposal services, audits, provision of inspection documents. Electrical appliances are all around us these days. It is important to understand that many fires occur due to short circuits and at a time when no one is present so that they can intervene immediately.
At normal temperatures, up to 250 g of a fire extinguisher is retained in this relatively small space thanks to the 5 bar pressure. The start-up of the system itself is activated by temperatures above 120 °, when the softened polyamide wall explodes precisely at the places with the highest thermal stress and releases the exhaust gas into the space. It reliably and effectively extinguishes the fire in the embryo and does not damage electrical components during extinguishing, even during operation. The entire system is fully automatic, does not require an operator, and starts immediately when a fire breaks out.
A complex of this type operates on the basis of oxygen reduction as a result of the supply of non-combustible gases directly to the ignition zone. In addition, the method of liquidation can be not only voluminous, but, if necessary, also local.
Powder fire extinguishing
According to current regulations fire safety and maintenance of the urban economy as a whole, all administrative and public buildings, premises of a production or warehouse type must be equipped with powder fire extinguishing systems.
In this case, the flame is extinguished due to the instant supply of a non-toxic, finely dispersed powder composition directly to the ignition zone. Ease of use and relatively low cost with no damage to equipment and premises are the main advantages of such installations. The results of using these systems can be easily canceled by ordinary cleaning. The only drawback is the limited shelf life.
Design and installation of fire extinguishing systems
The installation of automatic fire extinguishing in accordance with the current requirements is a whole complex of specialized technical equipment designed for quick localization of internal fires. Such a complex includes monitoring and control systems, sprayers and pipelines, as well as devices and tanks containing extinguishing agent. Installation is the most costly stage of providing the facility with reliable fire protection. It is carried out after the design of all the necessary fire extinguishing equipment, as well as fire alarm.
The technical design of fire extinguishing complexes implies a number of the following goals.
- The discussed installations should be as modular as possible, connected to separate control units, which increases the overall performance.
- The functionality of the general and separate branches can be provided if there is a wireless connection between each unit and the control unit. This completely eliminates the likelihood of failure when low-current lines are broken under the action of open flame or high temperatures.
- The fire alarm and the installation itself must have several independent sources of electrical power at once, although this somewhat complicates the maintenance of fire extinguishing systems.
- The places of the most probable fires must be equipped with automated powder or aerosol fire extinguishing systems.
In general, the design of the discussed complexes is determined by with total area the object under consideration, the condition and nature of the materials located on the territory, as well as the category of fire and explosion hazard, the presence of service personnel.
Service maintenance of fire extinguishing installations is a set of specific works that are carried out at a specified frequency and ensure long-term, trouble-free operation of communications, a significant reduction in energy resource costs.
Water fire extinguishing service
Localization and complete extinguishing of fires with water is still the most popular technique. At the same time, the complexes using water are the most complex and require constant, enhanced control. Therefore, we will consider in more detail the maintenance of a sprinkler and just a water system.
Standard instructions and a list of maintenance of such a complex, as a rule, have about 20 points. It all starts from external inspection of parts and ends with complex tests.
The entire mechanism is obliged to function offline. Of course, what to completely isolate from others engineering communications its impossible. Therefore, you should have a backup additional element for plumbing (or water tank), power supply and pump.
The main difficulty of maintenance lies not only in maintaining the functionality of all elements of the system, but also in establishing good and constant communication between them. For example, turning on should be accompanied by an alarm, and a drop in pressure - turning on an additional pump.
It is enough to consider the internal fire-fighting water supply of the residential storey building, which must be present by law. It is known that the device of such a water supply system is approximately comparable in complexity to a household water supply system. Indeed, various difficulties with water supply often appear in the house, such as insufficient pressure, malfunctioning taps or primary leaks. Exactly the same problems can arise with fire-fighting water supply... The difference is that the consequences are real danger for the residents of the house.
Therefore, the discussed water supply is often duplicated. automated system... Of course, the maintenance of fire extinguishing installations is much more difficult and requires professional skills. For example, drencher complexes receive a signal from incentive systems or external sensors... Such a system requires periodic verification of the reliability of the connection between the drencher and the sensor. In turn, the sprinkler mechanism is a heat-sensitive device that collapses when exposed to high temperature, and requires constant appropriate care.
As you can see, the described modern systems are quite difficult to operate and maintain. But at the same time, it is they who can save human lives, health, or material values in case of fire.
