3. MAIN DESIGN SOLUTIONS

3.1. Automatic fire alarm installation.

3.1.1. Fire alarm is an integral part of the complex of engineering and technical systems for fire protection of the building and serves for timely detection of fire, transmission of information on fire to the central control panel of fire protection systems and generation of a pulse for control of engineering life support systems of the building.

3.1.2. The design provides for fire detection using fire alarm equipment and transfer of fire information to the control and receiving device to the personnel room.

3.1.3. The fire alarm system is built on the basis of the integrated Orion security system of Russian production, which has a certificate of conformity and a certificate of fire safety.

3.1.4. Automatic fire alarm equipment is provided for all rooms and corridors of the shopping center, electric switchboard, gas boiler rooms with the exception of rooms with wet processes - bathrooms, washing rooms, refrigerating chambers, as well as technical rooms where there are no combustion materials of the ventilation chamber.

3.1.5. Smoke address-analog fire detectors of "DIP34A" type are installed in the above rooms. Automatic fire detectors are installed on the floors of protected rooms. Manual fire detectors of type "IPR5133A" are installed on the escape routes. An alarm when a fire is visually detected is sent by destroying a plastic window.

3.1.6. The technical implementation of the Orion integrated security system is based on the use of the head (master control) network controller of the system, as which the C2000M monitoring and control panel is used.

On the basis of Orion equipment, a combined system was built that combines the functions of a fire alarm system and the management of the building's engineering systems. The Orion integrated security system provides a modular construction structure, is multifunctional and economical, has an addressable construction principle, which ensures the monitoring of the state of each fire detector separately and the state of the system elements of the entire fire protection complex via a two-wire address alarm loop through the S2000KDL controller. Loops are formed according to the ring principle, which makes it possible to communicate with detectors on both sides during a break. Branches from the ring loop are provided in small sections. To protect the address line from short circuits, installation of "Breeze" branching-isolating units is provided.

3.1.7. The fire alarm system generates signals for the control of the building's engineering and fire systems in case of fire: - disconnection of general ventilation; - cessation of gas supply; - activation of the fire warning system for people; - generation of the "Fire" signal to the local bodies of "State Supervision." Information is provided on liquid crystal indicator of control and monitoring panels in Russian language. The messages are easy to read, and the address information necessary for accurate detection of the fire or malfunction area in the system is displayed. All elements of the system are in constant diagnostic mode and any deviations from the norm are displayed accordingly on the panel screen and are accompanied by an audio signal, and the fire sound signal differs in tone from the fault signal. 3.1.8. In standby mode, the network controller monitors the serviceability of detectors, connecting, address and interface signaling lines. If the interface line and address lines with fire detectors are damaged, a fault signal is output. 3.1.9. In case of fire, smoke detectors operate in the protected room. When fire detectors are activated, the network controller issues acoustic and light alarms indicating the address of the triggered detector. 3.1.10. Smoke fire detector "DIP34A" operates in the mode of address threshold detector, independently making a decision when the smoke threshold is exceeded. When smoke approaches "Fire" threshold, "Attention" signal is generated. If the detector dust exceeds the critical level, a "dust" message is sent to the network controller. This signals the need to clean the smoke chamber. 3.1.11. The notice on the fire and condition of installations of the fire alarm is displayed on the display of the C2000M remote controller, the block of indication "by S2000BI, established in personnel of the mall with the round-the-clock personnel on duty. 3.1.12. To transmit a fire signal via a radio channel to the territorial bodies of the State Supervision Service, contacts are formed on the executive relay unit SP1 is.01, which, if necessary, are connected to the transmitter. 3.1.13. Wiring is made by non-spreading cable laid in installation boxes and corrugated PVC pipes. 3.1.14. According to PUE, fire alarm installations in terms of ensuring the reliability of power supply are classified as electrical receivers of the 1st category, therefore, the power supply of the plant is carried out from two independent sources. As a backup source, storage batteries designed to provide power to the system for 24 hours in standby mode and 3 hours in "Fire" mode are used. The project uses three 17A/h batteries. 3.1.15. Detailed information on the operation of the control instrument and fire detectors is given in their technical descriptions. 3.1.16. To ensure the safety of people, elements of electrical equipment of the automatic fire alarm installation must meet the requirements of GOST 12.2.007.0. All metal parts of electrical equipment that are not normally energized, but which may be under it, due to failure of insulation, are subject to grounding (earthing). The potentials must be balanced.

Protective grounding (grounding) must be performed in accordance with the "Electrical Installations Design Rules" (PUE, Edition 7, Chapter 1.7), SNiP 3.05.0685 "Electrical Devices," the requirements of GOST 12.1.03081 and technical documentation of manufacturers of components. The resistance of the grounding device shall be not more than 4 ohms and shall be provided by the customer.

3.2. Fire warning system for people.
