Introduction

The project is executed on the basis of contract No. ____ by PR ___________ from _____. ______. 2012, the specification, basic data provided by the Customer. The development of this project "Automatic fire alarm installations" (OPS) is caused by the need to detect primary signs of fire in protected premises and penetrate the protected facility.

AUPS complex is designed for installation in rooms located in a separate building of a domestic building

1. common part

Purpose of the system.

Automatic Fire Alarm Installation (AUPS) - Automatic Fire Alarm Installation (AUPS) - a set of technical means for fire detection, processing, presentation in a given form of a fire notification, special information and issuing commands to technical devices.

The Evacuation Warning and Control System (ESMS) is a set of organizational measures and technical means designed to timely inform people about the occurrence of a fire and the need for evacuation.

Automatic and semi-automatic (according to the operator's signals) monitoring of alarm elements status is performed.

When fire information is received at PKU, the duty officer sends a fire message via the telephone line to the console of the Unified Dispatch Rescue Service of the Ministry of Emergencies of the Russian Federation in Mezhdurechensk.

3.1 Fire Alarm Organization

3.1.1 Basics of the complex construction, arrangement of instruments

On the basis of SP3.13130.2009 and SP5.13130.2009, a design decision was made to protect the facility with an automatic fire alarm system equipped with smoke and manual detectors (Working documentation 003012AUPS).

The project provides in accordance with SP5.13130.2009 protection of AUPS of all premises of the facility regardless of the area, except for the premises:

- with wet processes (showers, bathrooms, cooled chambers, washing rooms, etc.);

- ventilation chambers (plenum, as well as exhaust, not servicing production rooms

category A or B), pump water supply, boiler and other rooms for engineering equipment of the building in which there are no combustible materials;

- categories B4 and D by fire hazard;

- staircases.

According to SP5.13130.2009 p.p. 13.2.2, the maximum number and area of rooms protected by the same address line with address fire detectors or address devices is determined by the technical capabilities of the reception and control equipment, the technical characteristics of the detectors included in the line and does not depend on the location of the rooms in the building. At the same time, a ring loop with branches connected to it by means of short circuit avoidance devices is more preferable before radial.

According to SP 5.13130.2009 item 13.3.3 It is allowed to install one automatic fire detector in the protected room or dedicated parts of the room, if the following conditions are met at the same time:

a) the area of the room is not more than the area protected by the fire detector specified in the technical documentation for it, and not more than the average area specified in Tables 13.3 - 13.6;

b) automatic serviceability check of the fire detector is provided under conditions of external environment factors, confirming its performance of its functions, and a notification of serviceability (malfunction) is generated on the control and receiving device;

c) provide identification of the faulty detector by means of light indication and possibility of its replacement by duty personnel within the set time determined in accordance with Appendix O;

d) upon fire detector actuation no signal is generated for control of fire extinguishing units or fire warning systems of the 5th type according to [15], as well as other systems, false functioning of which can lead to unacceptable material losses or decrease of safety level of people.

Control of a condition of announcers is made via the S2000KDL controller. Controllers are installed see sheet 8 - 10 Work documentation 003012AUPS. In "Fire" mode, the system through address relay units provides activation of warning devices, with line control. As well as turning off the ventilation. Manual detectors are installed at the exits, and at the exits from the floors.

The number of automatic fire detectors is determined by the need to detect fires in the controlled area of ​ ​ the room.

To control the system, the monitoring and indication unit is installed in the "duty guard" room (room No. 41 of the first floor), the output of all information and complete control of the system is carried out through the security post, round-the-clock duty is organized.

Removal/installation of fire alarm for protection is performed through C2000M PCM, C2000BKI monitoring and indication unit. This system is connected to ISO Orion with the output of information to the security unit of PSC Alpha. Communication with the Orion system is carried out using the RS485/232 interface converter to the local network (C2000Etheta).

3.2.3 Voice announcement.

According to SP3.13130.2009, in the building of the domestic building for 2, 3 there should be equipped with CO of the third type: voice automatic (recording and transmission of special texts) and light (light indicators "Output").

The notification shall be carried out by translating voice information about the need for evacuation and other actions aimed at ensuring safety.

Evacuation management shall be carried out by:

- actuation of evacuation lighting;

- Transmission of specially developed texts on JI aimed at preventing panic and other phenomena that complicate the evacuation process (crowding of people in passages, etc.);

translation of texts containing information on the need for a direction of movement;

- actuation of direction of motion light indicators.

The warning system shall be controlled from the security room (fire station). First of all, there is an alert to the security service, and then all the others according to a specially designed sequence. To provide this type of warning, the equipment of NPO "Bolid" is used: voice warning device of RUPOR series "Horn 01." This device controls the warning line to the acoustic modules. The project selected acoustic modules of the type "Orpheus" AM Spanish. 01 with wall mount. The AM data has a power of 3W and a resistance of 8 ohms.

AM were arranged taking into account the peculiarities of the premises.

The selection of this equipment is due to the type of alert system, the large area of each alert area, the installation of a large number of speakers in one alert area. The equipment used has a fire safety certificate. Alerts used in the system do not have regulators

Volume and are connected to the network without detachable connections .

Notification is performed from C2000M monitoring and control panel in automatic mode corresponding to actuation of a specific detector. The stored alert modes are enabled according to the programmed tactics in each evacuation scenario. In the event of a change in the alarming situation, the evacuation tactic changes to the next evacuation scenario. Programming of the device for tactics and recording of the evacuation scenario is performed after installation of the AR system and coordination with the responsible persons.

The diagram of the warning system is provided in the drawings.

3.2.5 Light warning

Light annunciators indicate the direction of evacuation.

Light annunciators are installed of "Lightning 24V" type ("EXIT" green):

Warning signs, their colors and place of installation are selected according to SP3.13130.2009.

4. Selection and installation of cable products.

4.1 Selection of wires and cables, methods of their routing.
