Purpose and principle of automatic installation of powder fire extinguishing and fire alarm

Automatic installation of powder fire extinguishing based on powder fire extinguishing modules of WFP type(p) 12IGEUKhL cat.3.1 TU4854002580107302005 (trademark "Garant12"), type WFP (p) -7-I-GE-UKhL cat.3.1 TU4854002580107302005 (trademark "Garant7"), type WFP (p) -5-I-GE-UHL cat.3.1 TU4854002580107302005 (trademark "Garant5"), type WFP(p) 8VIGEUKhL cat.3.1 TU4854006524593342001 (trademark "Buran8") and WFP type (p) -8-I-GE-UKhL cat.3.1 TU4854006524593342001 (trademark "Buran8") in explosion-proof design, with explosion protection marking - 2ExdsIIBT4X (WFP (r) -8 (Vz)), in the version "Wall" is intended for fire detection, localization and extinguishing, in accordance with GOST 12.3.04691 in protected rooms and issuing a fire alarm to the room with the permanent presence of duty personnel.

Powdered fire extinguishing modules WFP (p) 12IGEUHL cat.3.1, WFP (p) -7-I-GE-UHL cat.3.1 and WFP (p) -5-I-GE-UHL cat.3.1. have fire safety certificate No. SPB.RU.OP014.V.R.00636, certificate No.

PPKPU "URSCP (bp) have fire safety certificate No. SSPB.RU.OP021.B.00286, compliance certificate No. ROSS RU.OS03.H00286.

In accordance with NPB 11003, all rooms are subject to protection by fire alarm installation, except for wet process rooms (bathrooms), water metering unit and other rooms for engineering equipment of the building, staircases, as well as rooms of categories B4 and D for fire hazard (in the absence of combustible material in them).

Based on the characteristics of the premises equipped with automatic fire alarm and automatic powder fire extinguishing system, the type of fire load, the features of the combustion center development, the design provides for protection of the premises using the following types of fire detectors:

Rooms of the warehouse case it is protected by thermal announcers of SP 1033A21M.

The premises of the administrative building are protected by smoke fire detectors ISP 2123SU, the signals from which are transmitted to the instruments receiving and control security and fire protection "Signal 20P SMD."

Smoke fire detectors ISP 2123SU installed behind the false flags have remote light indicators VUOS1 in accordance with NPB 882001 (para 12.23).

Manual fire detectors IPR 5133 are installed on the escape routes and at the exits in accordance with Annex 13 of NPB 882001, the signals from which are also transmitted to the "20P SMD Signal" security and fire control devices.

The method of extinguishing in the warehouse premises is local in area.

The mechanism of extinguishing powder compositions used in WFP (p) Garant consists in inhibiting the active centers of the combustion center and isolating the combustible medium.

In accordance with NPB 882001 (item 12) in the Working design, the area controlled by one fire detector, as well as the maximum distance from the detectors to the walls and between the detectors, does not exceed the values ​ ​ given in Table 1.

In accordance with NPB 882001 * (p.13.1) in the Operating Design, the distance between fire detectors is reduced by half, since the automatic fire alarm system controls fire extinguishing, warning, ventilation, smoke removal and elevator blocking.

At least three fire detectors are installed in each room (p.13.3 NPB 882001).

In order to increase the efficiency of the fire extinguishing unit operation, to prevent spontaneous actuation of all modules, the Working Design uses a posture extinguishing. Protected rooms are divided into 69 extinguishing zones.

At actuation of one fire detector in the alarm loop at the output of URSCP (bp) the signal "Attention" is generated (sound signal is triggered and corresponding indicator is illuminated).

SCCP of URSCP (bp) provides disconnection of automatic fire extinguishing equipment starting mode.

At simultaneous actuation of two fire detectors "Fire" signal is generated in the alarm loop at the output of CCPCS (bp). After delay time 30 ± 5 s. Control pulse U = 12 V is generated for starting of the zone with powder modules of PWP (p) in which the fire occurred.

To extinguish the fire in case of its visual detection, the "Manual start" mode of fire extinguishing equipment is provided in the ULRTsP PPKU (bp).

USRTCP (bp) are installed on the wall at a height of about 1.5 m from the floor.

SCCP of URSCP (bp) are located in the warehouse in groups in order to minimize the length of cable communication lines. The distance between instruments of one group is 50 mm. Compliance with the requirements of item 12.48 of NPB 882001 is provided by the operating mode of the enterprise. Fire or malfunction notices shall be sent to the dispensary room with permanent presence of personnel on duty.

SCCP of URSCP (bp) provides continuous check of alarm loops serviceability and fire extinguishing equipment start-up.

ULRSCP (bp) is a complex electronic device assembled on the basis of integrated circuits of large and medium degree of integration. The microprocessor in the ROM of which the control program is recorded controls the whole operation of the ULRTCP (bp). The device is designed to receive alarm signals from fire detectors installed in protected rooms, monitor the integrity of communication lines between them, start fire extinguishing equipment and issue a status signal to the PSK.

In case of fire, CCCP URSCP (bp) outputs sound and light signals indicating the number of the loop that detected the fire. The project provides for the installation of Svirel sounders. The number of alerts, their arrangement and power provide the necessary audibility in all places of possible stay of people.

The device is powered from 220V, 50 Hz mains. Start of WFP fire extinguishing modules (p) is performed from built-in power supply source with output voltage of 12 V with load current up to 3A through control circuits of CCCP of URSCP (bp).

When protecting one fire extinguishing zone, the extinguishing command is generated when two fire detectors are triggered at the same time, which excludes the launch of automatic fire extinguishing means when false actuation occurs on one of the detectors.

Receiving and control devices (PPK) are designed to receive alarm signals from PPKPU URSCP (bp), fire detectors and to monitor the integrity of communication lines between them. As PPK devices are used - reception and control safety and fire protection devices "Signal 20P SMD."

Alarm loops with fire detectors shall be formed in accordance with the requirements of "SMD 20P Signal" PPKCP and URSCP (bp) PPKCP. Signal reception from fire detectors is performed by means of control of current value in circuits of alarm loops.

At drawdown in the protected room of two firefighters izveshchatnly in one SS or the tame fire announcer "the International Party of Russia 5133" the corresponding device "Signal 20P SMD" via the C2000M control panel turns on the corresponding relay in the Signal 20P SMD device or S2000SP1 blocks, which include warning, smoke removal, open smoke removal valves, close fire protection valves, supply and exhaust ventilation are switched off, signals are sent to lower elevators to the first floor. For control, relays of four devices "Signal 20P SMD" No. 2125 and eleven devices "C2000SP1" is.01 No. 111 are used to switch control circuits with currents up to 10A and voltage up to 280 in.

For extension and galvanic isolation of the RS485 interface line with short circuit protection, two converters of the S2000PI interface No. 1-2 located on 3 and 6 floors are used.

For visual control of a condition of the alarm system and fire extinguishing of all floors and drawdown of the alarm system two blocks of indication "S2000BI" serve (rooms 209) established in dispechersky.

All messages are displayed and registered on the C2000M control panel.

Functional diagram of the powder fire extinguishing and fire alarm system is shown in the drawing of PR. 30/15 PT.PS Sheet 2.

Fire loops of type 1 "Signal 20P SMD" devices allow you to determine the double operation of detectors in one loop. When the detector goes off, the device removes the power from the loop (reset the notification) and supplies it again. If within one minute there is no repeated drawdown of the announcer, the device forms and transfers to "C2000M" the message "Drawdown of the sensor" and remains in the mode on duty. This eliminates false fire alarms. If the detector is actuated again within one minute after the first tripping, the device issues a notice "Warning." When another detector is triggered in this loop, the device issues a "Fire" message. The C2000M device having received the message "Fire" through RS485 interface the relay of Signal 20P SMD and S2000SP1 devices on inclusion of the notification, smoke removal, etc. operates.

Power supply of all devices of the system (with the exception of CCCP of URSCP (bp)) is carried out from four redundant DC power sources (RIP) with a voltage of 24 V "Scat2400 I7."

On the basis of NPB 882001 (Appendix 13), to send a signal about a fire in case of its visual detection, it is provided to place manual fire detectors of the IPR type on the escape routes, at the exits of the room.

Automatic fire detectors of each loop control not more than ten isolated or adjacent rooms leaving in one corridor, which corresponds to item 12.13. NPB 882001.

The automatic powder fire extinguishing unit consists of the following main functional units and devices:

start-up loops with WFP powder fire extinguishing modules (p);

ULRSCP (bp) with built-in uninterruptible power supplies;

alarm loops with fire detectors.

Functional diagram of the unit is given in Fig. 1.
