3. Description and characteristics of the object

Commercial and office complex on ave. Hamidova in Makhachkala, the construction of which is planned according to an individual project, is a six-story building with an attic and basement.

On the basement there is an underground car parking, which consists of one compartment with an area of ​ ​ 565.8m2 and designed for 16 cars. Autoparking has one entrance and one emergency exit. The entrance to the parking lot and the spare exit are located dispersed .

The walls of the buildings are reinforced concrete, the internal partitions are stone. Floors and ceilings made of concrete slabs. The windows in the buildings are different types, plastic. Heating is an autonomous boiler house. Operating temperature limits from + 5С to + 30С.

On the basement there are also technical rooms.

Dust, smoke formations, vibration, aggressive media and significant electromagnetic interference in the premises of the shopping and office complex are absent. However, smoke formations and dust content may be present in the underground autoparking room.

4. The main technical solutions adopted in the project:

1) Automatic fire alarm installations

All fire alarm equipment shall be equipped

underground car parking rooms.

The signal reception and processing equipment is an address control device (PKP) Signal 20P SMD with a capacity of 20 loops, installed in the autoparking checkpoint room with round-the-clock security on the basement floor. The C20P device is integrated into the common system using the Signal2000 programming and control panel installed in the same room. Programming of S20P SMD receiver-and-monitor, C2000 KPB test and start-up units, S2000SP1 relay unit in order to establish individual addresses, selected parameters and modes, as well as control of the entire integrated system is carried out from the keyboard of C2000 panel. Programming is also possible from a personal computer using the Pprog and Uprog programs.

Fire alarm of autoparking consists of 6 fire loops connected to inputs of SCP C20P SMD (1) (14 standby inputs). Input 1 monitors the condition of fire detector loops in the checkpoint and technical rooms. Inputs 2-6 monitor condition of fire detector loops in auto-parking compartments.

Technical means of fire detection at an early stage of development are:

• Smoke optical fire detectors IP2donbass 4; (installed at the checkpoint and in other technical rooms, except for wet production rooms, stairways and toilets).

• Fire detectors of type "Spectron202" (installed in the car parking room in the basement, where there can be a high concentration of dust, the presence of exhaust gases of cars, through holes).

When choosing the type of fire detectors, environmental conditions, the purpose of the premises, the probability of a fire and the dynamics of its development are taken into account.

The facility uses Russian-made PS equipment with certificates of compliance in the field of fire safety.

Fire detectors are included in independent fire alarm loops, which are connected with "No disconnection right" function on C20P SCP. Fire loops in the premises where the AUPT installation is provided during programming are assigned type 1 (double operation with re-request). The output of alarm messages from the C20P device is carried out on an external light-and-sound annunciator of the MCS 1 type, installed in the checkpoint room with round-the-clock presence of personnel, as well as the possibility of displaying signals to the centralized monitoring panel (PCP) of the ROVD, the Ministry of Emergency Situations.

According to the signal from fire detectors, PKU S2000 generates signals for starting the fire warning system of the 2nd type as per SP3.13130.2009 "Fire warning and evacuation control systems, Fire safety requirements" and control equipment that enables the automatic installation of powder fire extinguishing. Automatic fire alarm installation is designed for 24-hour continuous operation.

2) Automatic fire warning and control system

evacuation of people

Fire Warning and Evacuation Management System (EPMS) is designed for timely warning of people about a fire in the initial stage of its development. EPSS complies with SP3.13130.2009 "Fire Warning and Evacuation Control Systems. Fire safety requirements. " EPSS is an integral part of the complex of technical means of fire protection .

To notify people about fire in accordance with SP3.13130.2009 (Table 2. item 17) in the auto-parking room of the shopping and office complex there is a type 2 warning system (sound warning) with installation of Blik12 "EXIT" light alerts above the exits of the premises on the escape routes at an altitude of 2.5 m from the floor.

Sound notification is performed on the basis of AC10 dual-tone annunciators. The number of annunciators is selected based on the need to ensure the audibility of alert signals in all rooms with people staying. EMSS sound signals shall provide a common sound level together with all signals produced by the annunciators at least 75db at a distance of 3m from the annunciator, but not more than 120db at any point of the protected room. AM are attached at a height of at least 2.3m from the floor level, but the distance from the ceiling to the annunciator must be at least 150mm.

ECSS control function is performed by C20P SCP via relay output 1. PKP C20P shall be programmed to issue to relay output 1 command to actuate ECSS when one fire detector or manual detector is activated.

To increase reliability of fire detection in C20P SCP it is necessary to program the function of reacquisition of fire detector actuation. During programming of SCP C20P relay 1, ECSS control function is assigned (program 3). EPSS shall operate for the time required for evacuation of people, but not less than the estimated duration of evacuation (26 seconds from auto-parking). Therefore, the switching time 35 seconds is programmed for relay 1 of SC20P (1) SCP device.

3) Automatic installation of powder fire extinguishing

According to the Code of Rules SP5.13130.2009 "Automatic fire alarm and fire extinguishing installations. Design rules and regulations "premises for storage of vehicles in basements and underground floors located in buildings of other purpose (Table A.3, item 25.1) shall be equipped with automatic fire extinguishing units (AUPT).

The project provides for the construction of AUPT based on Buran15I powder fire extinguishing modules (WFP). They belong to the pulse type of action - the time of powder release in these modules does not exceed 1 second. Due to this, the intensity of powder supply is 10 times higher than the standard - about 3 kg/m2 .

Modular powder fire extinguishing installations can be used both to extinguish the entire area or the entire volume of the room to be protected, and to locally extinguish part of the area or volume. In the Buran fire extinguishing modules, the Phoenix ABS70 and VexonABS powder is used. Powders are chemically inactive, non-aggressive and do not have a poisonous effect on people.
