Design of fire extinguishing installations is quite not an easy task. Making a competent project and choosing the right equipment is sometimes not so easy, not only for novice designers, but also for engineers with experience. There are many objects with their own characteristics and requirements (or their complete absence in regulatory documents). Seeing the need among our clients, TC TAKIR developed a separate program in 2014 and began regularly conducting training on the design of fire extinguishing installations for specialists from different regions of Russia.
Training course “Design of fire extinguishing installations”
Why many students chose TC TAKIR and our fire extinguishing course:

- We do not have the task of selling you equipment from a specific manufacturer or convincing you to include it in the project;
- Lectures discuss the requirements of the standards and the specifics of their application;
- we are aware of current changes in regulatory documents and legislative acts;
- Hydraulic calculations are discussed in detail in the classes;
- contacts received during training may be useful to students in their work. You can get an answer to your question faster by writing directly to the teacher by email.
Fire extinguishing design training is provided by:
Practical teachers with more than 10 years of experience in the design of fire extinguishing systems, representatives of VNIIPO and the State Fire Service Academy of the Ministry of Emergency Situations of Russia, specialists from leading companies providing consulting services on the design of fire protection systems.
How to enroll in fire fighting courses:
Courses are held once a quarter. Employees training center We advise you to sign up for them in advance by filling out an application on the website or by phone. After reviewing your application, staff will agree on a training date. Only after this you will be sent an invoice for payment and a contract.

This is the most critical stage of work, preceding the immediate installation of the water fire extinguishing system. To draw up a correct project, you need to know all the quantitative and qualitative characteristics of the equipment for each room. It is also necessary to accurately calculate the results of the interaction of the fire extinguishing system with other engineering networks(different remote controls and sensors must have different power sources, the water supply system must have a backup pump, backup systems and other points).
The safety of material assets and people’s lives depends on the successful completion of this stage. Moreover, if a mistake is made in the project, then even the most best editing may turn out to be useless. You can’t save money here, but no one wants to spend too much either. Therefore, let's understand the process of installation and selection of a water fire extinguishing system.
Types of water fire extinguishing systems.
The entire range of water fire extinguishing systems popular today can be divided into two parts: sprinkler and deluge. First the best way suitable for suppressing local fires in various rooms. The latter work better to prevent the spread of a fire.
Water fire extinguishing sprinkler systems are simpler in design and therefore easier to install and commission. These devices are also highly reliable due to the simplicity of the actuation mechanism (overheating causes the valve to deform and water begins to flow into the room).

Appendix B. METHOD FOR CALCULATING PARAMETERS OF AUP FOR SURFACE FIRE FIGHTING WITH WATER AND LOW EXPANSION FOAM
IN 1. Algorithm for calculating AUP parameters for surface fire extinguishing with water and low expansion foam
B.1.1. The type of fire extinguishing agent (sprayed or atomized water or foam solution) is selected depending on the class of fire at the facility.
B.1.2. The type of fire extinguishing installation is selected taking into account the fire hazard and speed of flame spread - sprinkler or deluge, modular or modular or sprinkler-deluge, sprinkler with forced start.
Note - In this Annex, unless otherwise specified, a sprinkler means both the actual water or foam sprinkler and the water spray.
B.1.3. The type of fire extinguishing sprinkler system (water-filled or air-filled) is set depending on the operating temperature of the AUP.
B.1.4. Determined according to temperature environment in the area where sprinklers are located, the nominal temperature of their operation.
B.1.5. Taking into account the selected group of the object of protection (according to Appendix B and tables 5.1 - 5.3 of this SP), the intensity of irrigation, the consumption of fire extinguishing agent (FMA), the maximum area of irrigation, the distance between sprinklers and the duration of supply of FMA.
B.1.6. The type of sprinkler is selected in accordance with its consumption, irrigation intensity and the area it protects, as well as the architectural and planning solutions of the protected object.
B.1.7. The pipeline network layout and sprinkler placement plan are outlined; for clarity, the routing of the pipeline network through the protected object is depicted in axonometric form (not necessarily to scale).
B.1.8. The dictating protected irrigated area is highlighted on the hydraulic plan diagram of the AUP, on which the dictating sprinkler is located.
B.1.9. A hydraulic calculation of the AUP is carried out:
It is determined taking into account the standard irrigation intensity and the height of the sprinkler location according to irrigation diagrams or passport data, the pressure that must be ensured at the dictating sprinkler, and the distance between the sprinklers;
Pipeline diameters are assigned for various sections of the AUP hydraulic network; in this case, the speed of movement of water and foam concentrate solution in pressure pipelines should be no more than 10 m/s, and in suction pipelines - no more than 2.8 m/s; the diameter in the suction pipelines is determined by hydraulic calculation, taking into account the provision of cavitation reserve of the fire pump used;
The consumption of each sprinkler located in the accepted dictating protected irrigation area is determined (taking into account the fact that the consumption of sprinklers installed on the distribution network increases with distance from the dictating sprinkler), and the total consumption of sprinklers protecting the area irrigated by them;
The calculation of the distribution network of the sprinkler AUP is checked based on the condition that such a number of sprinklers are activated, the total consumption of which and the intensity of irrigation on the accepted protected irrigated area will be no less than the standard values given in Tables 5.1 - 5.3 of this SP. If in this case the protected area is less than that specified in tables 5.1 - 5.3, then the calculation must be repeated with increased diameters of the distribution network pipelines. When using sprayers, the irrigation intensity or pressure at the dictating sprayer is assigned according to regulatory and technical documentation developed in accordance with the established procedure;
The distribution network of the deluge AFS is calculated based on the condition of simultaneous operation of all deluge sprinklers of the section, ensuring fire extinguishing in the protected area with an intensity not less than the standard (Tables 5.1 - 5.3 of this SP). When using sprayers, the irrigation intensity or pressure at the dictating sprayer is assigned according to regulatory and technical documentation developed in accordance with the established procedure;
The pressure in the supply pipeline of the calculated section of the distribution network protecting the accepted irrigated area is determined;
The hydraulic losses of the hydraulic network from the design section of the distribution network to the fire pump are determined, as well as local losses (including in the control unit) in this pipeline network;
Its main parameters (pressure and flow rate) are calculated taking into account the pressure at the inlet of the fire pump;
The type and brand of fire pump is selected based on the design pressure and flow rate.
AT 2. Distribution network calculation
B.2.1. The layout of sprinklers on the AUP distribution pipeline is most often carried out according to a symmetrical, asymmetrical, symmetrical ring or asymmetrical ring design (Figure B.1).
B.2.2. The calculated flow rate of water (foaming agent solution) through the dictating sprinkler located in the dictating protected irrigated area is determined by the formula:
d_1-2 - diameter between the first and second sprinklers of the pipeline, mm;
Q_1-2 - waste water consumption, l/s;
mu - flow coefficient;
v - speed of water movement, m/s (should not exceed 10 m/s).
B.2.5. Pressure loss P_1-2 in section L_1-2 is determined by the formula:
Q_1-2 - total consumption of waste water of the first and second sprinklers, l/s;
K_t - specific characteristic pipeline, l^6 / s^2;
A is the resistivity of the pipeline, depending on the diameter and roughness of the walls, s^6 / l^2;
B.2.6. Resistivity and specific hydraulic characteristics of pipelines for pipes (from carbon materials) various diameters are given in Table B.1 and B.2.

B.2.7. Hydraulic resistance plastic pipes is taken according to the manufacturer's data, it should be taken into account that, unlike steel pipelines, the diameter of plastic pipes is indicated by the outer diameter.
B.2.8. Pressure at sprinkler 2:
| R | = P | + R | . | |||
| 2 | 1 | 1-2 |
B.2.9. Sprinkler 2 consumption will be:
B.2.10. Features of calculating the symmetrical scheme of a dead-end distribution network
B.2.10.1. For a symmetrical scheme (Figure B.1, section A), the calculated flow rate in the area between the second sprinkler and point a, i.e. on section 2-a, will be equal to:
| Q | = q | +q | . | |||
| 2-a | 1 | 2 |
B.2.10.2. The diameter of the pipeline in section L_2-a is assigned by the designer or determined by the formula:
B.2.10.4. The pressure at point a will be:
| R | = P | + R | . | |||
| a | 2 | 2-a |
B.2.10.5. For the left branch of row I (Figure B.1, section A), it is required to provide flow Q_2-a at pressure P_a. The right branch of the row is symmetrical to the left, so the flow rate for this branch will also be equal to Q_2-a, therefore, the pressure at point a will be equal to P_a.
B.2.10.6. As a result, for row I we have a pressure equal to P_a and water flow:
The diameter is increased to the nearest nominal value according to GOST 28338.
B.2.10.8. The hydraulic characteristics of the rows, made structurally identical, are determined by the generalized characteristics of the design section of the pipeline.
B.2.10.9. The generalized characteristic of row I is determined from the expression:
B.2.10.11. The pressure at point b will be:
B.2.10.13. The calculation of all subsequent rows until the calculated (actual) water flow rate and the corresponding pressure are obtained is carried out similarly to the calculation of row II.
B.2.11. Features of calculating an asymmetrical dead-end network scheme
B.2.11.1. The right side of section B (Figure B.1) is asymmetrical to the left, therefore the left branch is calculated separately, determining P_a and Q"_3-a for it.
B.2.11.2. If we consider the right side of row 3 (one sprinkler) separately from the left side of row 1 (two sprinklers), then the pressure in the right side P"_a should be less than the pressure P_a in the left side.
B.2.11.3. Since there cannot be two different pressures at one point, a larger value of pressure P_a is taken and the corrected (refined) flow rate for the right branch Q_3-a is determined:
| Q_3-a = Q"_3-a | / | R_a / R"_a. |
B.2.11.4. Total water consumption from row I:
| Q | = Q | + Q | . | |||
| I | 2-a | 3-a |
B.2.12. Features of the calculation of symmetrical and asymmetrical ring circuits
B.2.12.1. Symmetrical and asymmetrical ring circuits(Figure B.1, sections C and D) are calculated similarly to a dead-end network, but at 50% of the calculated water flow for each half-ring.
AT 3. Hydraulic calculation of AUP
B.3.1. The calculation of sprinkler AUP is carried out from the condition:
| Q | <= | Q | , | ||
| n | With |
Q_н - standard flow rate of sprinkler AUP according to tables 5.1 - 5.3 of this SP;
