Characteristics of protected premises

The protected room is located on the 2nd floor of the building. Category of protected rooms according to explosion and fire hazard - B (according to NBP 10595), area class according to PUE86 - B2a. space settings:

-a total area of 30.7 m2.

there is no false floor.

There are no dust, smoke formations, vibrations and aggressive media in the protected rooms above the permissible limits.

The combustible load in the premises can be: insulation of cable wires, linoleum, furniture. Class of possible fire as per GOST 27.33187 - "A."

Air temperature in rooms is not lower than + 5 * С. With natural ventilation, relative humidity - no more than 70% at T = 20 * С, dust - up to 2mG/m3, air flow rate - up to 1 m/s, aggressive medium - absent.

In order to increase the level of fire protection of premises and tighten possible combustion centers at the facility, manual fire extinguishing devices are used.

MAIN DECISIONS TAKEN IN THE DRAFT.

The working design contains solutions for installation, installation of the automatic gas fire extinguishing system equipment, the premises of the server station located on the second floor of the Maple Production and Storage Complex.

The automatic gas fire extinguishing system, modular type, is made on the basis of the PPKP device "Poc2SL" (TU PL36.00.00.000TU), and the gas fire extinguishing modules MGP1640 (TU 48540013307508896PS) produced by ZAO ARTSOK (Chekhov).). Chladone 318C ("IGMER") is used as a fire extinguishing agent. The layout of the system equipment is shown on sheet 6.

The automatic fire extinguishing system has one direction and is designed to detect the fire source in the protected room, followed by a signal for starting the gas fire extinguishing module. Signals about fire and failure of fire extinguishing installation are output to base station inputs and further via service channel - to the price control room with round-the-clock stay of personnel.

Duplicate signals "Fire" and "Fault" from "Poc2SL" device are output to the fire control room of the building to the existing fire alarm station PPKOP "Signal20." Structural diagram of the system is given on sheet 5, electrical connection diagram is given on sheet 9.

Poc2SL is a 1-zone controller providing fire extinguishing in the 1st direction. In this direction, control of the fire alarm loop, control of the condition of the entrance doors, light and sound alarms about the fire, as well as the launch of the gas fire extinguishing module is provided.

To prevent false start of the fire extinguishing system, it is provided to actuate it from two sensors in the fire alarm loop or from the remote launch panel (RMP).

Principle of fire extinguishing system operation

In the standby mode of operation, the "Poc2SL" device constantly monitors the condition of the fire alarm loop in the protected room. In case of fire detection (operation of at least two sensors in the fire alarm loop), the "Poc2SL" device checks the signal validity by resetting the loop. At repetitive reception of "FIRE" signal, the device sets to "FIRE" mode. At the same time:

• on the device itself, the light and sound alarm about the fire is activated, a "FIRE" signal is output to the "ALARM" input of the base station and to the fire control room of the building;

• signals for ventilation shutdown (closing of air dampers) and process equipment shutdown (if necessary) are output;

• audible warning and "GAZ _ LEAVE" annunciators are ON inside the protected room;

• start of pre-start delay countdown;

• at the end of the pre-start delay (30 s. is installed during commissioning) the condition of the entrance doors of the protected room is checked. If the doors are open, restart the pre-start delay counter until the doors close at the end of the pre-start delay (30 s. set at commissioning) if the room doors are closed - start of gas fire extinguishing modules with + 24V, 4F pulse;

• solenoid shut-off valves of IHL modules from the starting current pulse open the heads - gates and discharge fire extinguishing gas through the distribution pipeline to the room volume

• when gas enters the distribution pipeline, the pressure switch (SDU) operates and outputs a signal about the plant actuation and fire extinguishing agent supply to the protected room;

• the fire extinguishing agent, entering the protected room through the nozzle, creates a fire extinguishing concentration with its vapors, which leads to the elimination of the fire.

If a fire has started in the room, which cannot be extinguished using improvised means, and the fire extinguishing system has not yet detected it, it is possible to start the system by remote start-up of the RDP installed outside, at the front door of each protected room.

In case of alarm loopback, failure of alarm sensors, break of fire extinguishing modules starting line, on "Rosa2 SL" device the light-and-sound alarm of alarm loopback or starting line failure is activated.

In case of loss of power supply voltage of main network 220V 50Hz, "Rosa2 SL" device automatically switches to power supply from built-in accumulator is sufficient for system operation during 24h in standby mode and not less than 30 min in fire mode. When restoring the voltage of the main network, "Rosa2 SL" automatically switches to power from the network, the battery goes into recharge mode.

In all cases, the system goes into the automatic start off mode when opening the entrance doors in the protected room. After closing the doors, the automatic start mode is restored by laying the corresponding Touch Memory key from the set of "Rosa2 SL" device to the reader installed on the STP.

PPKP device "Rosa2 SL" is installed in accordance with the requirements of paragraphs 4.22 - 4.27 of SNiP 2.04.09 - 84 in the protected room, the installation place is given on the equipment position plan. It is allowed to specify the installation place during installation in place.
