Key Technical Solutions

Selection of automatic fire alarm system (AFS) hardware was made on the basis of analysis of structural and construction characteristics and purpose of premises, taking into account requirements of technical specification, regulatory and guidance documents, tactical and technical characteristics and equipment cost.

The fire alarm of the hostel is organized on the basis of the Berezina automatic fire alarm system, the equipment of which is installed on the 1st floor in the security room (a place with permanent staff). The system also includes aerosol and gas fire extinguishing equipment (see sections APT2 and APT4).

Fire alarm system (setting, removal, alarm release, etc.) is controlled by "Berezina UKP 10/18 PS" control and monitoring panel. System status information is displayed on LCD display of "Berezina UKP 10/18 PS" panel and on "Berezina UKA 12.5/1 PS" device.

The automatic fire alarm system outputs control signals for actuation of the warning system by means of contacts of the relay module RM 24 of the Berezina system. The project provides for the output of "Fire" and "Malfunction" signals to the EMERCOM panel. There are also contacts for turning off ventilation.

Fire alarm is performed using automatic

fire smoke optoelectronic detectors IP2125M and manual fire detectors IPR3SU.

According to SNB 2.02.0201, a fire warning system of the SO-2 type is provided at the facility. Light-and-sound placards ASTO 12S/1 with the inscription "Exit," ASTO12S/12 with the inscriptions "Exit/Fire" and "Exit/arrow to the right" are used as warning devices. The warning system is controlled by Tango CP/BP8 device and area switches of Tango CP/CP.

Operation of the installation

In garages for autonomous aerosol fire extinguishing, fire extinguishing aerosol generators of the "BOR5" brand manufactured by UP Belspetsremont are used, designed for volumetric extinguishing of fires.

Fire occurrence in protected rooms is recorded by heat detectors IP10503/2, which react to heat. To detach from false positives, each point of the ceiling surface is controlled by two detectors. Fire alarm loops are installed on devices "Berezina UKA 12.5/1 AT" 2pcs, which work in the Berezina system together with fire alarm devices and gas fire extinguishing device. When two fire detectors are activated, the PPKPU device outputs a fire signal. The light and sound alarm is activated, informing the personnel of the fire and the need to evacuate people from the protected room. The time of evacuation of people from the protected room where the fire detectors worked is programmed on the instrument. After the evacuation of people, but not less than 30 seconds. fire extinguishing agent is supplied by pulse supply to "BOR5" generator electric initiator, membrane is opened, fire extinguishing agent is discharged as a result of which aerosol of required concentration is supplied to protected room, it is filled and combustion processes are stopped.

When opening the front door to the protected room, the installation is set to remote mode. In this case, the plant is started by the button on the PCKPU device or from the remote start buttons located at the entrance doors. The automation is restored from the dispatcher's console with closed entrance doors to the protected room.

The alarm panel of "Berezina UKP 10/18" instrument, isp. AR (see section of AUS). The design provides dry contacts for disconnection of ventilation systems in case of fire. For strengthening of contacts the PM 24 3/1 relay module is used (see the section AUS). The ventilation shutdown line is designed by the customer on the instructions of Belspetskproekt OJSC. Contacts are also provided to start the fire warning unit (refer to Section AUS).

Signals "Fire" and "Malfunction" are brought to point of scheduling of fire automatic equipment of the Ministry of Emergency Situations of RB, using an object repeater (see the section AUS).

Power supply of equipment

The fire extinguishing unit is a category 1 consumer and requires two independent power supplies.

Power supply of PPKPU devices "Berezina" is carried out by UKA 12.5/1 AT from the IRPA 124 BP VZ2 power supply considered in the section AUS.

Plant Maintenance Security Measures

During operation of aerosol generators refer to operating instructions and certificates for devices.

To ensure high-quality operation and maintenance of the GOA units, the person responsible for their operation must be appointed.

In the garages where the GOA units are located, it is necessary to exclude cluttering of the exhaust holes by the equipment, which will limit the jet during the operation of the GOA.

When working with generators, it should be remembered that they include ignition compositions.

In the event of a fire, persons who are at this moment in the protected room must quickly leave it, tightly closing the doors behind them,

windows, turn off ventilation and take no action to extinguish the fire.

It should be remembered that during the operation of the generators, the temperature of the gas aerosol flow at a distance of 0.5 m from it is about 100 ° C.

Do not:

strike generators;

use open fire and electric heating devices near generators;

smoke near generators.
