Complex testing of systems

Quality control should be carried out at each stage of the life cycle of automatic fire protection systems at the stage of design, installation and operation of the system. The efficiency of the system and its viability depends on many parameters. At the stage of commissioning the system, the level of compliance with the required parameters can be determined only when carrying out complex tests. Tests must be conducted in order to establish compliance with the requirements of the basic parameters of the relevant regulations.

The need for the procedure, development techniques and complex testing programs regulate the following documents - SP, GOST, SNIP, VSN, PNB, RD. For each type of automatic fire protection system the tests are conducted to meet the requirements of several documents that define how the general requirements for the rules acceptance and regulatory parameters that the system must comply with.

The tests should be performed before the commissioning of not less than 1 time in 5 years.

Complex tests must be carried out under the program and methodology, duly approved and coordinated with the supervisory bodies of the Ministry of Emergency Situations. The tests are usually carried out by enterprises (organizations), that operate such system, or by a specialized organization.

Techniques of complex tests are divided according to the type of fire protection system. Tests are carried out for:

·         automatic fire extinguishing systems of all types;

  • automatic fire alarm;
  • warning system and evacuation management;
  • automatic smoke protection system;
  • testing of taps on water loss.

Depending on the amount of works, the following tests are performed:

  • using impact of technical devices, that simulate the impact factors of fire, without triggering the extinguishing agent, on automatic fire extinguishing system;


  • using impact of technical devices, that simulate the impact factors of fire, with triggering the extinguishing agent, on automatic fire extinguishing system.


Furthermore, fire tests are divided into natural and model. Fire tests are usually carried out with the help of model fires, however, on especially important objects it is advisable to carry out full-scale fire tests. The program structure of the complex tests common to all types of automatic fire extinguishing systems. It may consist of the following sections.

An example of the program of comprehensive testing: water-filled sprinkler fire extinguishing system based on water mist, is mounted in the underground parking;

and a fragment of the program testing: smoke removal systems and pressurization of air with the launch of the smoke detectors.

I. The main characteristics of an object under test. 

It describes the basic technical solutions adopted in the project.

II. The purpose of the test.

The purpose of the test is to check the quality and conformity of assembling and commissioning works with the project documentation, the determination of the actual values, regulated by norms of fire protection system parameters, as well as its comprehensive probation. During testing is necessary to carry out: a comprehensive functionality check of the mounted system; a check of the irrigation intensity of protected area; a check of activation and issuance of all the necessary signals to the alarm control panel; check of overpressure. Fire tests were decided to be conducted on the model fire.

 III. Composition of the acceptance committee.

The chairman (usually a representative of the customer) and the members of the commission.

IV. The amount of tests and inspections.

The scope of the tests include: the executive documentation checking, visual inspection and testing of the system.

The program displays several versions of the system health validator. In coordination with the authorities and the decision of the acceptance committee, the tests can be carried out in full or optionally, taking into account the results of previous certification and other tests.

Let's consider some options for checking automatic fire extinguishing system efficiency, its interaction with the fire alarm system, as well as the issuance of operating impulses to technical equipment.

Variant 1. Conducting fire tests of the water-filled sprinkler fire extinguishing system based on water mist, using the model fire, as well as checking operation of the system with the launch of the extinguishing agent.

Initial condition: In the room chosen for the test, instead of just one sprinkler deluge sprinkler with ball valve (test valve) is twisted. The water pressure in the system is operating.

Preparing the model fire site, Class A (Figure 1.): Piles of five rows of bars stacked in a well, which forms square in a horizontal section, and attached to one another. Three bars are stacked in each row, forming a square (size 39 ± 1 mm and a length 150 ± 5 mm) in a cross-section. Middle bar is placed in the center parallel to the side edges. The stack is placed on the two steel angles (GOST 8510), set on concrete blocks or hard metal supports so that the distance from the bottom of the stack to the floor is 100 ± 10 mm. The length of the steel angle must be not less than the specified length of the bar. As a combustible material coniferous tree bars are used (not lower than grade 3 according to GOST 8486). Humidity of lumber should be between 10 to 14%. A metal pan (150x150 mm) with petrol is placed under the stack of bars to set fire to the wood.

Our organization has been conducting tests based on a certificate (in the certification system "quality and safety"), confirming the availability of qualified personnel and the necessary equipment.

According to the test results, we issue the certificate confirming the operability of the system.
