Heating is central. Operating temperature limits from + 5 ° С to + 30 ° С.

Relative humidity up to 70% at 20 ° C.

Dust, smoke, vibration, aggressive media and significant electromagnetic interference are 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.

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

Automatic installation of powder fire extinguishing on the basis of powder fire extinguishing modules of WFP type (p) -5-I-GE-UKhL cat.3.1 TU485002580107302005 (trademark "Guarant5") is intended for detection, localization and extinguishing of fire, in accordance with GOST 12.3.04691 in protected rooms and fire alarm signal (contacts 3.4 "CCS S S room

WFP powder fire extinguishing modules (p) -5-I-GE-UKhL cat.3.1 have fire safety certificate No. SPB.RU.OP014.B.00636, compliance certificate No. ROSS RU.H03.H00977.

PPKPU "URSCP (bp)" has 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:

- the laboratory (zone 1) is protected by thermal fire SP 1033A21M announcers.

.- office space (zone 2) is protected by smoke fire detectors of IDP 3.2 type.

The method of extinguishing in the laboratory room is by 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 * (para. 13) in the Working Design, the distance between thermal fire detectors is halved, since the automatic fire alarm system controls fire extinguishing.

Configuration of fire extinguishing zones is given in drawing PR 14/0125.PT.PS sheet 3.

At actuation of one fire detector in the alarm loop at the output of URSCP (bp) the signal "Attention" is generated (sound signal will be activated and the corresponding indicator will be illuminated), the warning system is activated.

ULRSCP (bp) provides switching off of automatic fire extinguishing equipment starting mode at opening of doors to laboratory room or switching of ULRSCP (bp) to "Manual operation mode" with illumination of "Automatic shutdown" annunciator.

At simultaneous actuation of two fire detectors "Fire" signal is generated in the signalling loop of zone 1 at the output of CCPCS (bp). After delay time 30 ± 5 s. Control pulse U = 12 V for starting of powder modules of WFP (p) "Garant5" is generated in PCCP of URSCP (bp ).

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) 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 great 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 sound annunciators "Oriole" and light-and-sound annunciators "Blick 3C12 ."

The device is powered from 220V, 50 Hz mains. Launch of modules of fire extinguishing of MPP (p) is made from the built-in power supply with the output voltage of 12 V load current up to 3A via UURSTSP PPKPU control circuits (bp)

The extinguishing command is generated when two fire detectors are triggered simultaneously, which excludes the start of automatic fire extinguishing equipment in case of false actuation by one of the detectors.

Alarm loops with fire detectors are formed in accordance with the requirements of the CCCP of URSCP (bp). Signal reception from fire detectors is performed by means of control of current value in circuits of alarm loops.

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.

General description of the protection area
