2. automatic fire alarm (aups)

All rooms except wet process rooms, staircases and rooms for engineering equipment of the building shall be protected by automatic installation of fire alarm with the voice of NPB 11003.

The fire alarm system provides receiving, processing and transmitting to the device the receiving and control signals supplied from automatic fire detectors installed in protected rooms.

The main functions of fire alarm are provided by various technical means. Detectors are used for fire detection, for processing and recording of information and generation of control alarms - receiving and control equipment and peripheral devices.

In addition to these functions, the fire alarm generates commands for actuation of fire warning systems and control of technological, electrical and other engineering equipment of the facility.

To obtain information about the alarm situation at the facility, the fire alarm includes detectors that differ from each other in the type of the monitored physical parameter, the principle of the sensor element operation, and the method of transmitting information to the central alarm control panel. The system presented in this project is address-analog. The address-to-analog fire alarm system (AA ATP) monitors the state of the environment in the room in dynamic mode, detecting in a short period of time the beginning of the change in temperature or smoke and issues a warning signal to the duty officer. The address-to-analog system uses a two-wire ring loop, which includes automatic and manual detectors, interface modules for control, dry contact control, non-address sub-shelf control, etc. Fire address-to-analog receiving and control panel (AA PCP) provides power supply to all devices connected to the system and exchanges information with them on the same pair of conductors. Each device connected to a loop has its own "address." The device exchanges information with each device, alternately in order of increasing addresses. The ring loop is connected to the output and to the input of SCP AA. If a loop break occurs, the ring loop is converted to two radial loops and the system remains fully operational, at the same time information about the fault location is displayed. If the loop is short-circuited, the near insulators on both sides automatically disconnect the faulty loop section. Thus, only devices located between adjacent insulators are excluded. Insulators are built into detector bases.

AUPS was developed on the basis of the equipment of ZAO NVP "Bolid."

The central core of the object system is the control and monitoring panel of C2000M CCP. SCP is designed for operation as part of the security and fire alarm systems for monitoring the state and collecting information from the system devices, keeping a record of events occurring in the system, indicating alarms, controlling the setting for protection, removal from protection, and controlling automation.

3. warning and evacuation control system (sooe) in case of fire

According to NPB10403 (Table 2, Item 7) for schools with the number of floors equal to 3 and the number of students 3511600, the III type of fire warning is designed.

The third type involves the following notification methods:

• Speech (transmission of special texts);

• Light (light indicators "Output").

Generation of a signal for activation of fire warning is performed from the control and receiving device at actuation of one fire detector.

The voice announcement at the school is divided into several zones: the first zone notifies the staff. The first zone includes premises in which the school administration and maintenance staff are located. The first zone is switched on automatically when the signal from PPKOP is transmitted to the alert control device. The second and subsequent zones notify all other rooms located on different floors of the building. Each floor is designated as a separate warning area. The second and subsequent zones are automatically or semi-automatically activated by the person in charge.

The scenario of evacuation of people is prescribed in the control unit and involves several evacuation options depending on the place of fire and the distribution of fire hazards.

In accordance with the "General Requirements" of NPB 10403 "Warning and Evacuation Management Systems for Fires in Buildings and Structures" and NPB 882001, the following are combined into a single complex:

• fire alarm system performing the task of fire detection and output

• command pulse for actuation of EMSS generated by automatic installation

• fire alarm and fire fighting,

• civil defence warning system,

• evacuation lighting system,

• light warning system including evacuation safety signs,

• access control system with remote opening of additional doors

• evacuation exits,

• sound warning system for sound signals and translation of texts: a)

• specially developed texts of speech information (recorded phonograms) and b)

• live translation of voice messages and control commands via microphone (i.e. "from voice")

• translational network of the building,

• external source of audio programs.

To combine these systems into a single complex of fire alarms, warning and evacuation of people, the Trombone-PU- 4 control device is used.

"Trombone - PU-4" warning and evacuation equipment control device is used for integration of fire alarm system, which provides output of command pulse for actuation of EPSS, civil defense warning system, with EPSS.

The control device receives command pulses generated by the automatic fire alarm and fire extinguishing unit and turns on the EMSS. Further, after processing command pulses, the device issues commands and signals to the sound and voice warning system, to the access control system, to the evacuation lighting system and the light warning system (inclusion of evacuation safety signs).

The device provides the following functions:

1) transmission of electrical signals to annunciators;

2) monitoring of communication line serviceability with annunciators;

3) automatic switching of power supply from the main source to the standby one and

back without false signals;

4) controls shall have protection against unauthorized access

outsiders;

5) monitoring the state of the standby power supply;

6) manual disconnection of sound alarm while maintaining light alarm.

7) possibility of alerting algorithm correction;

8) manual and (or) automatic serviceability check of bonds and instrument units;

9) remote opening of doors or additional evacuation exits.

In the PU4 Trombone monitor five "lines" or notification "zones". One is the first to alert staff, and four to alert people in four zones (floors).

In the control device, "independent activation of each line" is carried out, i.e. the warning in the line is turned on upon receipt of the command pulse coming from a specific fire alarm area (sensor actuation on the floor on which this warning line is located). This determines the subsequent sequence of alerts - first on the same floor and on the upper (zones of greatest danger), then (after the delay time) on the lower floors or "zones of lesser danger."

In the Trombone — PU4 monitor the lines of evacuation signs of safety join along with inclusion of the speech notification of zones. Safety evacuation sign activation lines and voice announcement lines operate independently of each other.

The warning sequence is implemented in the Trombone PU-4 control device as follows: when a command pulse arrives, first of all, personnel developed for it is notified via their line,

- further (after the delay time T1 expires) with a general text on the need for evacuation, the "dangerous" line or zone from which the command pulse came and all lines (floors) above - "high danger zones" is notified,

- at the last (after delay time T2), all zones are notified, including the lower floors - "zones of lesser danger."

"Verb-SM" loudspeakers are used to translate voice messages. Annunciators are used in wall design: (index H). Alerts are installed in each room with a permanent stay of people. Loudspeakers with a power of 1.3.5 or 10 watts are used to create the required sound pressure level determined by NPB 1042003, depending on the size of the room.

The frequency range of reproducible frequencies is significantly higher than the range defined in the BPU and ranges from 100 to 12000 Hz. The frequency response uniformity in the range from 500 to 5000Hz is not more than 3 dB.

The annunciators are connected to the 120V alert network.
