Bibliography

The number of point fire detectors installed in the room is determined by the need to solve two main tasks: ensuring high reliability of the fire alarm system and high reliability of the fire signal (low probability of generating a false alarm signal).

First of all, it is necessary to designate the functions performed by the fire alarm system, namely, whether the fire protection systems (fire extinguishing, warning, smoke removal, etc.) are triggered by the signal from the fire detectors, or the system only provides a fire alarm in the premises of the staff on duty .

If the function of the system is only to signal a fire, then it can be assumed that the negative consequences of generating a false alarm are negligible. Based on this premise, in rooms whose area does not exceed the area protected by one detector (according to tables 13.3, 13.5), to increase the reliability of the system, two detectors are installed, switched on according to the OR logic circuit (a fire signal is generated when any one of two installed detectors). In this case, in case of uncontrolled failure of one of the detectors, the fire detection function will be performed by the second one. If the detector is capable of testing itself and transmitting information about its malfunction to the control panel (meets the requirements of clause 13.3.3 b), c)), then one detector can be installed in the room. In large rooms, detectors are installed at a standard distance .

Similarly, for flame detectors, each point of the protected premises must be controlled by two detectors connected according to the OR logic scheme (a technical error was made in clause 13.8. logic circuit "OR"), or one detector that meets the requirements of clause 13.3.3 b), c).

If it is necessary to generate a control signal for a fire protection system, then when designing, the design organization must determine whether this signal will be generated from one detector, which is acceptable for the systems listed in clause 14.2, or whether the signal will be generated according to clause 14.1, i.e. e. when two detectors are triggered (logical "AND").

The use of the "AND" logical scheme makes it possible to increase the reliability of the formation of a fire signal, since a false operation of one detector will not cause the formation of a control signal. This algorithm is required to control fire extinguishing and warning systems of the 5th type. To control other systems, you can get by with an alarm signal from one detector, but only if the false activation of these systems does not lead to a decrease in the level of people's safety and / or unacceptable material losses. The rationale for such a decision should be displayed in the explanatory note to the project. In this case, it is necessary to apply technical solutions to improve the reliability of the formation of a fire signal. Such solutions may include the use of so-called "intelligent" detectors that provide an analysis of the physical characteristics of fire factors and (or) the dynamics of their change, providing information about their critical state (dustiness, pollution), the use of the function of re-requesting the state of detectors, taking measures to eliminate (reduction) of the impact on the detector of factors similar to fire factors and capable of causing a false alarm.

If during the design it was decided to generate control signals for fire protection systems from one detector, then the requirements for the number and arrangement of detectors coincide with the above requirements for systems that perform only the signaling function. The requirements of clause 14.3 do not apply.

If the fire protection system control signal is generated from two detectors switched on, in accordance with clause 14.1, according to the “AND” logical scheme, then the requirements of clause 14.3 come into force. The need to increase the number of detectors to three, or even four, in rooms with a smaller area controlled by one detector, follows from the high reliability of the system in order to maintain its performance in the event of an uncontrolled failure of one detector. When using detectors with a self-test function and transmitting information about their malfunction to the control panel (meets the requirements of clause 13.3.3 b), c)) two detectors necessary for the implementation of the "AND" function can be installed in the room, but on condition that the operability of the system is maintained by the timely replacement of the failed detector.

In large rooms, in order to save the time of generating a fire signal from two detectors switched on according to the “AND” logical scheme, the detectors are installed at a distance of no more than half of the standard one, so that the fire factors reach and trigger two detectors in a timely manner. This requirement applies to detectors located along the walls and to detectors along one of the axes of the ceiling (at the choice of the designer). The distance between the detectors and the wall remains standard.

Application of GOTV Freon 114V2

In accordance with the International Documents for the Protection of the Earth's Ozone Layer (the Montreal Protocol on Substances that Deplete the Earth's Ozone Layer and a number of amendments to it) and Decree of the Government of the Russian Federation No. 1000 dated December 19, 2000 "On specifying the time frame for the implementation of state regulation measures for the production of ozone-depleting substances in the Russian Federation, the production of Freon 114V2 has been discontinued.

In pursuance of International agreements and the Decree of the Government of the Russian Federation, the use of freon 114B2 in newly designed installations and installations whose service life has expired is recognized as inappropriate.

As an exception, the use of freon 114V2 in AUGP is provided for fire protection of especially important (unique) objects, with the permission of the Ministry of Natural Resources of the Russian Federation.

For fire protection of objects with the presence of electronic equipment (telephone exchanges, server rooms, etc.), ozone-non-destructive freons 125 (C2 F5H) and 227 ea (C3F7H) are used.

The project documentation must define the recipient of the fire notice to ensure that the tasks in accordance with Section 17 are completed.

At objects of functional hazard class F 1.1 and F 4.1, fire notifications should be transmitted to fire departments via a duly allocated radio channel or other communication lines in automatic mode without the participation of facility personnel and any organizations broadcasting these signals. It is recommended to use technical means with resistance to electromagnetic interference not lower than the 3rd degree of rigidity in accordance with GOST R 53325-2009.
