Fire alarm system; (ATP) - a set of technical means intended for detection of fire factors, generation, collection, processing, recording and transmission in the specified form of signals about fire, operating modes of the system, other information and, if necessary, output of signals for control of technical means of fire protection, technological, electrical and other equipment.

The technical solutions adopted in this project comply with the requirements of environmental, sanitary, fire and other applicable norms and rules and ensure safe operation of the facility for life and health of people, subject to the measures stipulated by the project.

Description and characteristics of the object

The object is a separate five-story residential building with a basement. The store occupies part of the first floor and the basement. In the basement there are technical rooms with a ceiling height of up to 3.5 m. The walls are capital, the floors are reinforced concrete. From the basement there is one exit to the street.

The trading hall is located on the ground floor of the building. Ceiling height from 3.5 m to 6 m. Capital walls, reinforced concrete floors. On the ground floor there are three exits to the street.

The total area of ​ ​ the fire compartment of the premises is 314.59.

Premises not subject to ATP protection are located on the facility: san. units, vestibules, refrigerators.

Selection of FP type is made on the basis of SNB 2.02.0504 and Appendix P. Smoke FP and thermal FP are selected for protection of premises.

There is no 24-hour post. The object is telephoned.

Basic System Technical Solutions

The developed system shall provide the following tasks:

monitoring of 8 fire alarm loops with backless PIs;

detection of fire factors (smoke, heat) in protected premises;

provision of "Norm," "Break," "Short circuit," "Fire" notices;

generation, collection, processing, recording and transmission in the specified form of signals about fire, system operation modes, other information to the observation point and to the dispatching point of RB fire automation;

output of signals for fire warning equipment start-up

output of signals for ventilation devices control.

ATP shall provide control of fire warning system and have function increasing reliability of fire detection.

When analyzing technical data, cost and other indicators, the A16512 device was chosen as the PPKP, which allows you to connect all alarm loops and use the capacity of the device as efficiently as possible.

Selection of ATP equipment is made on the basis of analysis of building design characteristics and purpose of premises, as well as on the basis of the following documents:

- "List of fire protection devices allowed for use in the territory of the Republic of Belarus";

- "Information list of fire protection equipment produced in RB"

By Union of Right Forces it is executed on the basis of PPKP A16512 and consists of the following components:

PPKP A16512;

VPU-A-16;

UD3T access device;

DS1990A, DS1991DS1996 Internal Key Reader

Relay module PM642;

Smoke fire detector IP2125MU;

Thermal fire detector IP1035;

Fire detector manual IPR3SU;

"Lightning" message transmission unit;

ZOS1M light-and-sound annunciator.

Fire warning system consists of the following components:

ASTo12S light-and-sound placard;

The system status is monitored by the instrument itself.

The fire alarm system (setting/removal, alarm clearing, etc.) is controlled by reading the DS1990A electronic keys through the access device UD3T.

The outputs of the relay of PKP "A16512" are programmed on dumping of food of smoke announcers, control of the warning system, control of the ventilation system and signaling on BPS "Lightning".

The fire alarm system is organized using fire smoke detectors IP2125MU, fire heat detectors IP1035 and manual detectors IPR3SU. Smoke fire detectors are powered by SCP, through relay 3 programmed for "smoke detector power release."

Each point of the protected surface is controlled by one fire smoke detector, but at least two in each room.

According to SNB 2.02.02, the object provides for a fire warning system of the SO-2 type with automatic start-up. Light-and-sound banners with the inscription "Exit" and "Fire" ASTO12S are used as means of indication of escape routes and sound warning about fire. These devices are connected to outputs of SCP A16512. ZOS1M light-and-sound annunciator is installed on the building facade. This device is connected to outputs of PKP MPS. The store alert system includes one alert area.

The installed placards ensure that the sound pressure level above the noise background (in accordance with TKP/OR/452.02-22-2006) exceeds by 10 dB .

Backup power supply of the SCP of the Warning System and current-consuming detectors is carried out from the storage battery with capacity of 18 A * h, which is installed in the SCP housing. The SCP and power supply units provide automatic charging and monitoring of the ACS condition. Calculation of the capacity of the batteries installed in the PCB housing and power supply units is given in Section 5.

According to SNB 2.02.0504, the output of signals on actuation and malfunction from the PPKOP "A16512" receiving and control fire protection device (through the relay 1,2 PKP) to the fire automation dispatch point (PDPA) of the Ministry of Emergency Situations of the Republic of Belarus. The BPS "Lightning" is used as a transmitting device.

ATP outputs signal for ventilation shutdown by opening of normally closed contacts of relay 4 of SCP A16512.
