3. process part

3.1. Main decisions made in the project

"3MTMNovecTM 1230" gas fire extinguishing agent is used as fire extinguishing agent for protected premises. In installations with a gas fire extinguishing agent (GOTV) Novec implemented a volumetric method of extinguishing fires, based on the cooling effect .

When supplying fire extinguishing agent, the following methods of starting the plant are provided :

a) automatic - from automatic fire detectors;

b) remote - from the manual fire detector installed in the protected room.

The project provides for 100% stock of GHTV, which is used in the event of fire in the protected room during the reloading of modules with the main stock and is stored in the warehouse of the organization providing service for fire extinguishing plants.

The reserve is provided in the volume sufficient to restore the operability of the plant, which worked in the protected room of the object.

The service life of the plant is at least 10 years.

The plant includes the following equipment:

1. The module of gas fire extinguishing of MPATMS 1230 about GOTV "3MTM NovecTM 1230" of 106 l with an operating pressure of 25 bars at 20 °C intended for storage and production of fire extinguishing substance. The module is supplied with a filled fire extinguishing agent .

2. Pressure switch intended for output of signal on actuation of installation is installed directly on shutoff-starting device of module.

Module is connected with pipeline by means of high-pressure hose. A nozzle is installed on the pipeline to uniformly disperse the 3MTM NovecTM 1230 GTV in the protected room.

3.3. Equipment placement

The main stock module is located in the protected room.

The module with reserve stock in accordance with SP 5.13130.2009 is stored in the warehouse of the facility or organization providing service for fire extinguishing units.

Piping is routed to walls and ceiling from the roof.

3.4. Requirements for installation and operation of the plant

Installation and operation of the gas fire extinguishing unit is recommended in accordance with the instructions of VSN 2509.67-85 "Rules for the production and acceptance of works. Automatic fire-fighting installations, "as well as requirements laid down in the technical documentation by the equipment manufacturers.

4.1. Main decisions made in the project

As control stations the installation of modular fire extinguishing in the project used the S2000m monitor (M) isp. 10 companies LLC Bolid (Russia). "C2000M" is the two-threshold device and provides performance of the following main functions:

- reception of "Fire" and "Fault" signals by one loop from smoke address optoelectronic fire detectors, as well as from manual fire detector;

- reception of information from the door position sensor, automatic start-up recovery device;

- monitoring the condition of loops, external circuits and devices and displaying the received information;

- formation of an output signal on the starting chain of S2000ASPT bringing the module of a system of gas fire extinguishing into work ;

- actuation of "Gas - leave!," "Gas - do not enter!," "Automation is off" light and light-sound annunciators;

- issuing a command to disconnect ventilation and process equipment;

- output of "Fire" signal to fire alarm system.

For fire detection the project provides installation of announcers of fire smoke optical-electronic DIP-34A-01-02

For remote start of the gas fire extinguishing unit in case of visual detection of fires, a manual fire detector (IPR3SU) is provided.

When the door is opened in the protected room (by the signal from the magnetic-contact annunciator), the automatic gas start mode is switched off and the installation sets to manual mode.

To restore the automatic start-up of the fire extinguishing system, an automatic start-up recovery device (CPA) installed at the entrance to the protected room is provided.

The project also provides for the installation of light and light-and-sound displays "Gas - leave!," "Gas - do not enter!," "Automation is off."

Delay of gas release from gas fire extinguishing unit, from the moment of sensors actuation or actuation of remote gas starting is not less than 30 seconds.

From the C2000M monitor (M) by means of dry contacts the signal output "Fire" is carried out

Multiplication and reinforcement of contacts is carried out by the Customer.

For indication, recording of states of "C2000ASPT" control device and equipment connected to it, remote control of control device devices, remote generation of "CP reset" command, the project provides for a price-tral indication panel (C2000PT) installed in the "Security Post" room, provided with round-the-clock maintenance personnel.
