Fire Evacuation Warning and Control System

Contents

1. GENERAL PART

1.1. The working design of automatic fire alarm installations and a fire warning system was developed for secondary school No. 18, located at 6a Marshal Vasilevsky St. Ivanovo

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

1.3. The initial design data was detailed 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 the fire, transmission of information about the fire to the central control panel of fire protection systems and generation of a pulse for the management of engineering life support systems of the building

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

- Construction Norms and Regulations 11-01-95 "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 3.05.06-85 "Electrical devices";

- "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. Main equipment has Russian certificates of conformity and fire safety

2. BRIEF DESCRIPTION OF THE OBJECT

2.1. The school is a three-story brick building

Protected rooms have the following characteristics:

- heated;

- relative air humidity up to 80%;

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

3. MAIN DESIGN SOLUTIONS

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

3.2. 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 the safe area

3.3. In accordance with SP 3.13130.2009, an automatic warning system of the third type is designed. EMSS of this type provides voice warning and actuation of "Output" annunciators

The design provides for voice announcement only, since the "Exit" lights are already present at the facility in accordance with the current standards

3.4. As voice annunciators the following type of annunciators are designed:

- "WP-06T" и "SWS-10";

3.6. The central equipment includes:

"RECHOR" automatic voice fire warning devices:

- ALS - automatic messages unit;

- BOOM-2 - power amplification unit, 2 pcs

3.7. Electrical wiring to the annunciators is made with a non-spreading cable and laid in a corrugated hose

3.8. 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 backup power source

3.11 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 3.05.06-85, GOST 2.1.030-81. Grounding resistance not more than 4 Ohm

4. OCCUPATIONAL SAFETY
