In this case, the diagram of the concentration of the used HFV in the area of ​ ​ the coating given in the AT is taken into account.

6.1. Automatic fire alarm

Automatic fire alarm is an integral part of the complex of fire protection systems and serves for timely detection of the fire source at the protected facility. The address signaling system is installed on this site.

One automatic fire detector is installed in the protected room or dedicated parts of the room, since at the same time the following conditions are met:

a) the area of the room is not more than the area protected by the fire detector specified in the technical documentation for it, and not more than the average area specified in Tables 13.3 - 13.6 of SP 5.13130.2009;

b) automatic serviceability check of the fire detector is provided under conditions of external environment factors, confirming its performance of its functions, and a notification of serviceability (malfunction) is generated on the control and receiving device;

c) identification of the faulty announcer by means of light indication and a possibility of his replacement with personnel on duty for the determined time defined according to the application About the joint venture 5.13130.2009 is provided;

d) upon fire detector actuation no signal is generated for control of fire extinguishing units or fire warning systems of the 5th type according to [15], as well as other systems, false functioning of which can lead to unacceptable material losses or decrease of safety level of people.

To detect fire centers, use DIP34A detectors. Fire smoke optoelectronic address detector IP21234A "DIP-34PA" (hereinafter - detector)

It is used in fire alarm systems and is designed to detect fires accompanied by smoke in closed rooms of various buildings and structures by registering optical radiation reflected from smoke particles and giving "Fire," "Warning" or "Norm" notifications in response to an address request from the control and control panel (PCC) "C2000" or AWS "Orion" through the controller of two-wire line "KL" 2000. In addition, the detector, at the request of the console, reports the current state corresponding to the level of smoke or dust of the smoke chamber. Based on this message, the console operator can decide to prevent or wait for the message "Attention" when smoke appears in the initial stage of the fire. Supports the DPLC _ v2.xx two-wire link protocol and allows you to obtain the DPLC voltage value at the point of its connection. The version of the software of "DIP-34A-01-02" is v.1.30. The detector can be tested using a laser tester from System Sensor or Astra941 from TEKO.

There are three options for attachment of PIA 34PA detectors. For installation to the solid surface, a connection socket is used, which is included in the supply of the detector. In addition, installation kits "MK1" (variant B) or "MK2" (variant B) can be purchased to attach the detector to the suspended ceiling .

Detector provides storage of exchange address via DPLS in nonvolatile memory. The address range is 1 to 127. The detector is delivered at 127. To set the address, you must send the command "Change device address" from the C2000 console or personal computer with the old and new detector address. In this case, the console or computer will display messages about disconnection of the detector by the old one and its appearance at a new address .

With the Program Device Address command, you can specify the address of the detector regardless of which address is currently assigned to it. This can be used in case of erroneous assignment of the same addresses to two or more detectors. To do this, from the console or computer, issue a command to program with the number of the desired address. After that, you need to press the light emitter or illuminate it with a laser tester beam. In this case, the console or computer will display messages about the detector connection at the programmed address. If the detectors had the same address, then there will be no message about disconnecting the detector at the old address. Record the assigned address on the Address label and glue it to the detector base.

In rooms with thermal processes (kitchen) we use thermal address detectors S2000-IP-02-02. Designed to protect objects from fires by controlling the rate of temperature rise and exceeding the threshold value.

The detector transmits ambient temperature values in degrees Celsius at the request of "C2000" control and control panel or "Orion" workstation. Power supply and information exchange of the detector are carried out via a two-wire communication line (DPLS) of the controller "S2000KDL." The version of the software of "S2000IP0202" is v.1.01. The detector supports the protocol of the two-wire communication line DPLS _ v2.xx and allows you to obtain the value of the DPLS voltage at the place of its connection. The detector can be tested using a laser tester from System Sensor or Astra941 from TEKO.

The detector is designed for continuous round-the-clock operation. The detector refers to recoverable, periodically serviced products.

Three versions of C2000IPPA detectors attachment are provided. For installation to the solid surface, a connection socket is used, which is part of the detector's rate kit. In addition, installation kits "MK1" (variant B) or "MK2" (variant B) can be purchased to attach the detector to the suspended ceiling.

To work, you must assign an address in the range 1 to 10 to the detector.

The announcer the firefighter manual address "513ZPA" (further - the announcer) is applied by the International Party of Russia in fire alarm systems and automatic fire fighting, is intended for manual formation of a signal of fire alarm or start of systems of fire automatic equipment .

The detectors work with the instrument "S2000KDL," which is part of the notification transmission system "SPI2000A."

The controller of the two-wire communication line "S2000KDL" is designed to protect objects from penetration and fires by monitoring the state of address areas (zones) that may be represented by targeted security, fire and fire detectors and/or controlled chains (CC) address expanders (AP), control outputs of address signal-start units connected in parallel to two-wire communication line (DPLS), issues of disturbing notices at operation of announcers or violation of KC AR on the C2000 control panel (UCP) (versions 1.20 and above) or a computer via the RS485 interface, also for local management of its own address zones and centralized management of zones included in sections of the system .

The controller can operate in the following operating modes:

- "Duty";

- "Diagnostics" (see item 3.2).

1.2.15 The controller distinguishes the following AU states depending on the type of AU and the specified zone type:

- "Norm" - there is no violation or malfunction of the zone;

- "Alarm" - detection of zone violation occurred;

- "Fire" - fire detection occurred in the zone;

- "Dust" - smoke chamber dust;

- "Fault" - internal failure of automatic control unit;

- "Break" - there was a break in the CC zone;

- "Short circuit" - short circuit of CC zone occurred;

- "Hull opening" - automatic control unit hull opening occurred;

- "Hull recovery" - the integrity of the automatic control unit hull was restored;

- "Instrument reset" - power supply or restarting of AP program was interrupted;

- "Incorrect answer" - from AU there is a constant incorrect answer;

- "Unstable answer" - from AU comes an unstable answer;

- "Connected" - AU connection occurred;

- "No DPLC1 communication" - contact on DPLC1 branch is lost;

- "No DPLC2 communication" - contact on DPLC2 branch is lost;

- "OFF" - automatic control unit is disconnected;

and the status of the two-wire link:

"Norma";

"Short circuit";

"No DPLS1 connection" - contact on DPLS1 branch is lost;

"No DPLC2 connection" - contact on DPLC2 branch is lost;

"DPLS accident."

The Signal 10 device is capable of operating both autonomously and as part of the Orion system network of devices under the control of a network controller, which is the C2000M monitoring and control panel. For start of pumps TRV we apply to signal output Blok control and starting "S2000SP1". Loops of the fire alarm are executed with application of KPSEngFRLS cable 1х2х0.75. RS485 interface cable is a cable of KPSEngFRLS 2x2x0.75 cable.

6.2. Evacuation Warning and Management System

Fire evacuation warning and control system is designed for timely warning of people in case of fire detection.

When forming a signal of detection of the center of ignition on loops of the automatic fire alarm the C2000 monitor via the block control and starting "S2000KPB", KOP24 V "EXIT" issues the command for start of annunciators of light-sound boards (C) and sound Bumblebee annunciators.

"S2000KPB" unit is designed for control of actuating devices (light displays, sirens, video cameras, electromagnetic locks, etc.), as well as fire modules and fire automation equipment

"Exit" light annunciators are installed:

- in rooms with simultaneous stay of 50 or more people - above evacuation exits;

- above evacuation exits from the floors of the building, directly outside or leading to the safe zone;

- in other places, at the discretion of the project organization, if, in accordance with the provisions of the code 3.1310.2009, the building requires the installation of "Exit" light indicators.

Firefighting light-and-sound annunciator KOP24S (hereinafter - the product) is intended for installation in internal premises of industrial enterprises, civil buildings and structures for light and sound warning of heat or other emergency situations, as well as for various information purposes.

To ensure conditions:

- EMSS sound signals shall provide a common sound level (constant noise sound level together with all signals produced by the annunciators) of at least 75 dBA at a distance of 3 m from the annunciator, but not more than 120 dBA at any point of the protected room,

- EMSS sound signals shall provide sound level not less than 15 dBA above permissible sound level of constant noise in the protected room. The sound level shall be measured at a distance of 1.5 m from the floor level;

install additional Bumblebee sounders. Loops of the notification are executed by a cable of KPSEngFRLS cable 2х2х1.0.

6.3. Gas fire extinguishing

To extinguish the fire in the protected rooms, the UGPT 150106 gas fire extinguishing module (Novek 1230) is used. The bottle is intended for storage of GTV. The gas extinguishing installation with application 3M™Novec™1230 (Novek 1230) differs in a wide line of the equipment: LLC Pozhtekhnika delivers seven options of cylinders, with a capacity of 8, 16, 32, 52, 106, 147 and 180 liters. Thus, the most economical configuration can be selected during design. The main configuration includes: a cylinder with GOTV 3M™Novec™1230 (Novek 1230), the valve for GOTV 3M™Novec™1230 (Novek 1230) and a siphon tube.

3M™Novec™1230 (Novek 1230) - the last development in the market of gas fire extinguishing substances (GOTV). Gas fire extinguishing agent is intended for fire extinguishing, including fire of combustible liquids, gases and components of electrical equipment. Note the last point: extinguishing electrical equipment. Gases do not conduct electricity and therefore the Gas Fire Extinguishing Plant (GFW) extinguishes electrical equipment without damage, unlike the installation of water, foam and powder fire extinguishing.

3M™Novec™1230 (Novek 1230) - the first "pure" gas for an ognetusheniye. It is safe for humans and the environment. Why did you need a novelty? What is her advantage? In order to answer these questions, let's see what gases have been used in fire extinguishing so far. Before emergence 3M™Novec™1230 (Novek 1230), in Russia in gas extinguishing installations (UGPT) were applied: - Hladona: Freon 114, Freon 125, Freon 227, Freon 318, - inert gases: carbon dioxide, nitrogen, argon, - Inergen. Pro-analyze their composition and method of fire extinguishing.

Level of filling of cylinder 3M™Novec™1230 (Novek 1230) is defined by room parameters. After filling with dried nitrogen, the cylinders shall be pressurized to 24.8 bar + 5 per cent (at 20 ° C). The maximum density of filling 3M™Novec™1230 (Novek 1230) is 1.2 kg/l, minimum - 0.5 kg/l.

The cylinders are painted red. Instructions are fixed on the cylinders. Cylinders are designed for operation only in vertical position.

The shut-off and start-up device (ZPU) ensures the release of the fire extinguishing agent during the standard time - not more than 10 seconds. The operation of the ZPU is based on the principle of pressure difference: the body is made of copper-zinc alloy, and the piston is made of stainless steel. The RAM is actuated by a solenoid and manual launcher.

Actuation of any of the starting devices results in pressing the nipple valve, the pressure above the piston is released, after which the valve is completely opened under the influence of the pressure in the bottle. The Zapornopuskovy device for cylinders 3M™Novec™1230 happens two sizes: 25 and 50 mm, depending on the capacity of the used cylinder. To determine the pressure in the cylinder, a pressure gauge is included in the standard configuration of the system. A safety bursting disc is inserted into the valve, it is destroyed at a pressure of 50 bar, i.e. at a temperature of more than 80 ° C (at maximum tolerance of filling density). A universal pressure switch is included in the delivery set of the RAM. It monitors the operating pressure in the module, i.e. gas leakage, and the supply of GTV when the module is activated. If the pressure in the cylinder falls below 18 Bar in standby mode, the relay outputs a "dry contact" type signal. Presence of built-in SDU makes it possible to refuse to install universal pressure switch on distribution pipe. In normal mode, the relay has N.R.K. (N.O.).

The solenoid drive is used to activate the module by means of an electrical signal. The drive is an electromechanical device, which, when activated, moves the central rod down, which mechanically acts on the starting nipple of the RAM. Solenoid operating voltage - 24V, actuation current - 0.2A DC. The solenoid is installed on the upper threaded connection of ZPU. From one main module, up to 10 slave modules can be controlled, connected by a pipe with a maximum of 30 m from the drive device. A second main module shall be provided to connect additional modules or to install a longer pipeline. Note: Before the solenoid is installed, the central rod must be returned to the initial position, otherwise the bottle valve will go OFF and the GTV will be released.

Nozzles sprays are intended for release of GOTV Novec™ 1230 (Novek 1230) in the protected room. The design of the nozzles is designed to ensure the optimal mode of mixing of the fire extinguishing composition with ambient air and uniform distribution of the GTV over the volume of the protected room with a concentration not lower than standard. The nozzles are made of aluminium or copper alloy and have internal at-connection thread and holes for exhaust of GTV.

The device reception and control and managements of automatic fire extinguishing means and S2000ASPT annunciators is used to autonomous fire-prevention protection of objects on one zone of fire extinguishing.

The device is powered by:

- main power supply (MV) - AC mains, rated voltage 220 V, frequency 50 Hz;

- standby power supply (RP) - from 2 batteries, rated voltage 12 V, 4 A/h.

The device is designed for round-the-clock operation.

The device provides monitoring of two SGs having the following parameters:

- resistance of SB wires excluding terminal resistor - not more than 100 ohms;

- leakage resistance between LC wires or each wire and ground - not less than 50 kOhm.

The plume is used to detect a fire under the ceiling.

Smoke IP 2123SU detectors are used to detect fire in loops.

The detector is designed to detect sunbathing, accompanied by the appearance of smoke in closed rooms of buildings and structures for various purposes. In case of smoke in the detector area, it generates an electrical signal about the fire that has occurred, recorded by the C 2000ASPT instrument.

Electrical power supply of the detector and transmission of the "Fire" signal are performed via a two-wire alarm loop. Actuation of the detector is accompanied by activation of the built-in optical indicator. The detector has built-in overload protection at actuation, limiting current flow through the detector to not more than 30 mA. 2.5. The detector is designed for continuous operation at ambient temperature from minus 40 to plus 60 ° С and relative humidity up to 95 ± 3% at temperature 35 ° С.

Signal of detector actuation is preserved after end of action of combustion products on it. The minimum detector holding current is 5 mA. Actuation signal is reset by polarity adjustment or disconnection of detector power supply for at least 2.5 ± 0.5 s.

Instrument S2000ASPT distinguishes between the following states of DS door and manual start-up circuits:

- "Norm";

- "Violation";

- "Break";

- "Short circuit."

Condition of door and manual start DC circuits is determined by its parameters. Integration time (minimum time of disturbance recorded by the instrument) for door DS circuits, automatic control system manual start circuits and SDU circuit is 300 ms.

For control of a chain of DS of a door the magnetocontact announcer of IO 1022 (CMK1) is used. The detectors consist of a magnetically controlled sensor based on a reed coat and a master element (magnet). Detectors issue "Alarm" notification by opening the reed reed clock to the receiving and monitoring device, concentrator or centralized monitoring panel.

When monitoring the manual starting circuit, use the manual fire detector IPR3SU .
