1. common part

1.1. The working design of automatic fire alarm installations and a fire warning system for people was developed for boiler room 37, located at 201 Normandio Neman St., Ivanovo.

1.2. The development organization of the project LLC "SP FPB Plus" - has a license to perform this type of design work.

1.3. The initial design data was measured drawings of the construction part issued by the customer.

1.4. 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.

1.5. The working design is developed in accordance with the requirements

- Construction Norms and Regulations 110195 "The instruction about an order of development, coordination, a statement and structure of the project documentation on construction of the enterprises, buildings and constructions ";

- SNiP 3.05.0685 "Electrical devices";

- NPB 882001 * "Fire fighting and alarm units. Design Codes and Regulations ";

- NPB 11003 "List of buildings, structures, premises and equipment to be protected by automatic fire extinguishing units and automatic fire alarm"

- SNiP 210197 * "Fire safety of buildings and structures";

- NPB 10403 "Design of fire warning systems for people in buildings and structures";

- "Electrical Installation Rules" (PUE), sixth and seventh editions;

- departmental regulatory documents

1.6. During the design, decisions, equipment and materials corresponding to the latest achievements of domestic science and technology were made. The main equipment has Russian certificates of conformity and fire safety.

Brief description of the object

2.1. In accordance with the above documents, all rooms and corridors of the boiler house building are equipped with fire alarms, with the exception of bathrooms, washing and other rooms with wet processes, as well as staircases and other technical rooms where there are no burnt materials.

2.2. The boiler room is three one-story separate buildings.

Protected rooms have the following characteristics:

heated;

relative humidity up to 80%;

air flow rate is not more than 1 m/s.

3. main design solutions

3.1. Automatic fire alarm installation.

3.1.1 The design provides for the registration of the fire by means of the "HunterPro" Safety and Fire Control Device (PPKOP) and the transfer of fire information to the EMERCOM console.

3.1.2. The fire alarm system is constructed on the basis of the systems of transfer of notices Andromeda, PPKOP of "SignalVK2" and the equipment of radio control by the security alarm system "Reef Ring ".

3.1.3. In standby mode, receiving and control devices located in the room of the shift supervisor in the DKVR boiler room and in the personnel room of the III lifting station monitor the serviceability of detectors, connecting lines and alarm loops. In case of damage of trunks and loops with fire detectors, a fault signal is output via the line to "HunterPro" CCCP.

3.1.4. In case of fire, smoke detectors of type IP2123SU, IP212-4SB or flame detectors of type Pulsar 1011P are activated in protected rooms. In case of fire detectors actuation, the control and receiving device generates acoustic and light alarms indicating the number of the area in which the activated detector is included.

3.1.5. Manual fire detectors of the type IPR3SU are installed on people's evacuation routes.

3.1.6 The selection of fire detectors of the specified type is justified by the most complete compliance of their parameters with the characteristics of the protected premises.

3.1.7. Detailed information on the operation of the control instrument and fire detectors is given in their technical descriptions.

3.1.8. Fire alarm system generates command pulse for actuation of light and sound fire warning system.

3.1.9. This project provides for communication via a telephone line with the central city security panel (EMERCOM). For these purposes, the project generated a duplicate fire signal from the zones to the Andromeda notification transmission system. It includes the "HunterPro" control panel, the RX150 keyboard, EXP1001 expander, and the VU20 voice module. The system enables the transmission of duplicate notifications via a radio channel or a dedicated telephone line. The customer determines the type of communication with the central fire department.

3.1.10. For communication between the station of the II-nd rise and the boiler house DKVR in the project were the radio control equipment is put by the security alarm system "Reef Ring" which is intended for transfer of the message about the arisen fire with PPKOP of "SignalVK2" on PPKOP of "HunterPro" on a radio channel.

3.1.11. The fire alarm system belongs to category I of reliability of power supply and, according to PUE, it is provided with electricity from 2 independent power sources. Storage batteries are used as backup power supply source in fire alarm system.

3.2. Fire warning system for people.

3.2.1. All rooms with permanent or temporary stay of people shall be equipped with fire warning system.

3.2.2. The fire evacuation warning and control system is one of the components of the complex of technical means and organizational measures that ensure the safety of people in case of fire or other emergency.

The fire warning system is designed to inform people about the fire and control their evacuation to a safe area.

3.2.3. In accordance with NPB 10403, an automatic warning system of the second type is designed. EMSS of this type provides audible warning and actuation of "Output" annunciators.

3.2.4. The following type of annunciators are designed as light annunciators:

- in the boiler room and oil pump station "BlikS24";

- at the III lifting station "BlikS12."

The following type of annunciators are designed as audible annunciators:

- in the boiler and mazutnonasosny station "AC24";

- at the station of the II-nd rise "AC10".

3.2.5. The fire warning system consists of central equipment, annunciators and a communication line.

3.2.6. The central equipment includes:

PPKOP of "HunterPro", PPKOP of "SignalVK2", switch of "UKVK/04" and stand-by power supply.

PPKOP of "HunterPro", PPKOP of "SignalVK2" provides turning on of sound and light annunciators.

3.2.7. Wiring to the annunciators is made with a non-spreading cable and laid in a corrugated hose.

3.2.8. Power supply of the warning system is provided according to the 1st category, as per PUE, from two independent power sources after ALT. Storage batteries are used as a backup power source.

3.2.11 To ensure safe operation of the warning system before the installation of the device housing, it is necessary to ground them to the protective grounding bar. Protective grounding is provided in accordance with PUE, SNiP 3.05.0685, GOST 2.1.03081. Grounding resistance is not more than 4 ohms.
