Automatic fire alarm and warning systems. Upgrade of odoriza node

General part

The technical solutions adopted in the project comply with the requirements of environmental, sanitary, fire and other applicable norms and rules, and ensure safe operation of the facility for life and health of people, subject to the measures provided by the project.

The following regulatory and technical documents were used in the development of the project:

SNB 1.03.0296 "Composition, procedure for development and approval of design documentation in construction";

SNB 2.02.0201 "Evacuation of people from buildings and structures in case of fire"

PUE "Electrical Installation Rules," sixth edition;

SNB 2.02.0504 "Fire automation";

NPB 152004 "Field of application of fire alarm systems and fire extinguishing systems"

GOST 30331.395 (MEK.36444192) "Electrical installations of buildings. Part 4. Safety requirements. Protection against electric shock. "

The initial design data was the approved design assignment and drawings submitted by the customer.

Description and characteristics of the object

The object is a one-story separate capital building.

Height of protected rooms up to 4.5 m.

The facility is located at: Pinsk.

Key Technical Solutions

Selection of automatic fire alarm system (AFS) hardware was made on the basis of analysis of structural and construction characteristics and purpose of premises, taking into account requirements of technical specification, regulatory and guidance documents, tactical and technical characteristics and equipment cost.

The fire alarm is organized on the A606 device which is installed in operator.

Control of the fire alarm system (setting, removal, clearing of alarms, etc.) is carried out from the A606 device using the access key. The system status information is displayed on the A606 device.

Fire alarm is made using automatic fire smoke optic-electronic detectors IP 21241M, thermal 1035IB and manual fire detectors AC05.

Thermal detectors IP1053IB are used in explosive rooms, and loops are output to intrinsically safe BiOP00 unit.

According to SNB 2.02.0201, a fire warning system of the SO-2 type is provided at the facility. As means of the notification light-sound banners of ACTO12C2 with the inscriptions "Exit/fire" and ACTO 12C with the inscription "Exit" are used.

In explosive rooms placards with degree of

protection of IP54 ASTO12S-2 VZ.

Signals "Fire" and "Malfunction" are output to the EMERCOM panel. The project provides contacts for shutdown of ventilation.

Equipment placement

During installation of fire alarm system elements, refer to references on drawings, certificates and technical descriptions for used equipment and materials.

In the control room (place with permanent presence of personnel) the system equipment is installed: A606 device and BIOP00 unit at altitude 0.8-1.5m. The distance between instruments shall be not less than 0.05m.

Manual AC05 fire detectors are installed on the escape routes at an altitude of 1.5 m from the floor level. Place the installation of manual fire detectors according to GOST 12.4.009 and 12.4.026.

Fire alarm system detectors shall be installed in all rooms except the fireplace.

ASTO12 12 2 light-and-sound placards with "Exit/Fire" placards and ASTO light placards with "Exit" placards are installed above evacuation exits at altitude 2, 6 m .

Electrical wiring

The fire alarm network shall be wired by KSPV cable in the duct by walls and ceilings. In explosive rooms, make wiring using PVC wire open. Mark the ends of PS2, PS3 loops in blue.

Light-and-sound indicators of fire warning system are connected

by PVC wire, wire branching is performed through UKP boxes.

In explosive rooms, fire warning is wired in a water and gas pipe, branching is performed through CTO boxes, and passage through walls through KPL boxes.

The main power supply of the equipment is designed by the customer according to the task "PKI Spetsautomatics"

Power supply of equipment

The fire alarm unit is a category 1 consumer and requires two independent power supplies.

Working input 220B, 50 Hz moves the A606 device.

Calculation of battery capacity for A606 device.

Backup power supply for A606 device is provided from battery 12V, 7a/h and provides operation of fire alarm and fire warning unit during 24 hours in standby mode, 3 hours in

"alarm" mode for fire alarm and 1 hour in "alarm" mode for

notifications about the fire (is established in the A606 device ).

Calculation of battery capacity for VZ IP.

The standby power supply for the VZ IP power supply is provided from the battery 12V, 4 2a/h and provides operation of the fire alarm unit for 24 hours in standby mode and 3 hours in

"Alarm" mode (set in VZ IP).

Security arrangements

PLANT MAINTENANCE

To protect maintenance personnel from dangerous voltages that may occur on electrical equipment housings as a result of

insulation curing, grounding of electrical equipment housings is provided. Grounding of electrical equipment shall be performed by metal connection of its housings to neutral of power supply network of objects, for which a separate third, protective conductor, laid together with wires of other purposes, is used. When performing works, follow GOST30331.395 (IEC 36444192)

"Electrical installations of buildings. Part 4. Safety requirements. Protection against electric shock. "
