1. AUTOMATIC FIRE FIGHTING.
For fire extinguishing the following are provided:
-automatic installation of sprinkler water fire extinguishing with finely atomized water with installation of internal fire extinguishing valves on the supply pipelines to protect premises;
-interior fire water supply to protect office and auxiliary premises;
-equipment pumping station fire extinguishing
To protect the premises of the shopping center there is a water-filled sprinkler installation automatic fire extinguishing finely atomized water (water mist) using finely atomized water sprinklers CBS0-PHo(d)0.07-R1/2/P57.B3 "Aquamaster".
An automatic water sprinkler fire extinguishing installation consists of:
- supply pipelines;
- fire extinguishing station NS 70-65-3/100, which consists of
- pumping station module (MNS 70-65);
- module of two sprinkler control units MUU-ZS (MUU-3/100);
- module for connecting mobile fire fighting equipment.
Technical data of the fire extinguishing installation:
The “Potok-3n control device” manufactured by Bolid is used as a control device for the pumping station.
The "S2000M" remote control provides reception of signals, through addressable devices, from standard automatic addressable and manual call points, as well as technological sensors of fire extinguishing systems.
The system has an interface line, which is a two-wire communication line of the main structure with visual and audio indication of alarm and malfunction on the system devices. Possibility of programming devices for signaling the state of the fire extinguishing installation.
Additional installed modules allow for protection technical premises discrete smoke detectors, which are used for automatic control engineering systems; issuing information to light and sound annunciators, issuing sound alerts and documenting events. An indication module “S2000 BI isp.01” is installed in the duty personnel room, which allows for visual control of the operation of the automatic fire extinguishing pump station equipment.
A fire reservoir is used as a source of water supply.
To supply water to the pipelines of the sprinkler installation, booster fire pumps of the GRUNDFOS NB 50-257 type with a 30 kW electric motor (main and backup) are provided. Supply - 75 m3/h, with pressure - 81 m.
Operating principle of water fire extinguishing installation.
In standby mode, the supply pipeline (to the control units), supply and distribution pipelines are filled with water and are under pressure P = 0.5 MPa (50 m) created by the jockey pump.
Automation elements are in standby mode.
When a fire occurs in the protected premises, the temperature rises. An increase in temperature to 570C leads to the destruction of the glass flask of the sprinkler.
Opening the sprinkler leads to a drop in pressure in the supply and distribution pipelines.
The water pressure in the supply pipeline lifts the valve of the KS water-filled sprinkler valve of the "Bage" type.
When the valve of the control unit is opened, pressure alarms installed on the control unit generate a pulse to turn on the working booster pump for water supply, as well as a fire alarm (in case of failure smoke detectors earlier) and about the start of the installation.
If the working pump fails to create the design pressure Rcalc = 0.70 MPa, the backup pump is turned on and the working pump is turned off. Water flows through the open control unit through supply and distribution pipelines to the source of fire; the jockey pump is turned off.
Automatic start-up is carried out using the contacts of the Potok 3N device, which ensure the activation of the pumps of the fire extinguishing booster pumping station. Remote start of automatic smoke protection and warning people about a fire is carried out from manual fire detectors installed on evacuation routes. Manual start-up of booster pumps is carried out at the location of the equipment on the pump control cabinets.
After extinguishing the fire it is necessary;
- check the sprinklers and pipelines located in the combustion zone; if they fail, replace them;
- fill the distribution, supply and inlet pipelines with water;
- bring the opened control unit into working condition;
- bring automation elements into a state of control.
When operating the installations, it is necessary to carry out following rules:
1) repair work related to the installation and dismantling of equipment must be carried out in the absence of pressure in the unit being repaired;
2) cleaning and painting of pipelines located close to current-carrying elements is permitted only after removing the voltage from them and issuing a work permit;
3) persons involved in hydraulic tests must be in safe places or behind a specially provided screen at the time of testing;
4) hydraulic and pneumatic tests of pipelines must be carried out in accordance with the approved instructions for testing pipelines;
5) lubrication of engines while moving, tightening bolts on moving parts of mechanisms is not allowed;
6) instructions and safety posters must be posted in the premises of control units and in the fire extinguishing station;
7) carry out repair work on electrical equipment after turning off the power supply;
8) when carrying out adjustment, repair and maintenance work, it is necessary to take into account that when installing an automatic fire extinguishing system, when the voltage is removed from any control cabinet (box), a voltage of 220V, 50 Hz may be present on electrical devices, terminal blocks of this device, since the automation control circuits are interconnected , and the remaining sources are not de-energized, therefore, before carrying out the specified work, it is necessary to carefully study the power supply circuit of the installation consumers, then de-energize necessary devices;
9) when performing work with electrical equipment, dielectric mats and gloves are required;
10) when executed repair work portable lamps with a voltage not exceeding 42 V should be used;
11) all non-current-carrying parts of electrical equipment that may become energized as a result of insulation failure must be grounded (zeroed);
12) all work should be carried out only with working tools; the use of wrenches with extended handles, tool handles must be made of insulating material.
