Key Policy Decisions

4.1.2.1 Fire alarm (prompting smoke removal automation system).

Detectors "IP21250M" are designed to detect the ignition, accompanied by the appearance of smoke of low concentration and issue alarm notices in the form of loud sound signals. Detectors "IP2donbass 5" are designed to detect the ignition, accompanied by the appearance of smoke of low concentration and issue alarm notifications in the form of a jump-like decrease in the internal resistance of the detector, connected to the alarm loop, to a value of not more than 500 Ohm.

"IP21250M" detectors are powered by built-in battery of "Krona" type, voltage 9V. The "IP2Would" detectors are powered by the alarm loop from the control and receiving device.

As a rule, detectors are installed on the ceiling of protected rooms, in special cases specified in SP5.131302009 it is allowed to install on the wall at a distance of 0.1 to 0.3 m from the floor, including the dimensions of the detector.

Manual fire detectors IPR-I are installed on escape routes and staircases. Detectors are installed on the wall at a height of 1.5 m from the floor level. ADU system is started by signal from IPR-I

Equipment of the C2000M fire alarm, "Signal20M", S2000-SP1, S2000KPB and RIP12 stand-by power supply isp. 05 is installed in the automation cabinet and/or attached side by side on the wall in the electrical panel, in the technical subpole. To turn off ventilation, a VHCU unit is provided, 5 installed in also in the automation cabinet.

The Signal20M device is intended for control of a condition of loops of the fire alarm and valves of smoke removal, and issue of notices on internal and external sound and light annunciators.

The fire alarm system via RS485 interface transmits the operating signals to inclusion of the notification of the fire, shutdowns of ventilation systems and control of other engineering equipment by means of blocks alarm and starting "S2000SP1". The device is powered from 220 V mains, the backup power is supplied from 12 V/7 A * h battery built-in to RIP12.

Make fire alarm networks with non-combustible, low-smoke cable of KPSengFRLS grade of various capacities. Fire alarm cables and wires shall be laid open on walls and ceilings in plastic PVC boxes 15x10 and on walls between floors as per riser in plastic PVC diam.50. All connections shall be made in screw junction boxes or by soldering. Installation of detectors, control devices, wires and cables shall be carried out in compliance with applicable norms and requirements: SP 5.13130.2009, RD 78.14593 and PUE. Connect and configure the devices and detectors according to the manufacturer's technical documentation.

According to SP 12.131302009 fire warning system in buildings of this type is organized according to EPSS - 1 type (sound warning).

The fire warning system used allows receiving an alarm from the fire alarm system and automatically transmitting a voice fire warning signal to the warning area. Fire alarm loops operate around the clock in the "no disconnection" mode, the type of loop is installed "with recognition of double operation." When the "Fire" signal is received, the device outputs control signals to turn on the fire warning and turn on the smoke removal system in the corridor. AC10 sirens and "Exit" annunciators installed in corridors on the wall at the level of 10 cm from the ceiling are used for fire warning.

Cable distributing of the notification is carried out by cable VVGNG (A) FRLS 2x1.5. Warning cables in rooms and corridors are laid along the ceiling and walls in non-combustible metal shells Ø15mm laid in open areas, in PVC 40x25 mm cable channels or hidden in building structures .

All cable and wire connections shall be made in junction boxes. Install loudspeakers and other equipment in compliance with applicable standards and requirements: RD 78.14593, SP 3.131302009, PUE. Connect and configure the equipment according to the technical documentation supplied by the manufacturer.

Protective grounding and connection of instruments shall be performed in accordance with PUE, SNiP 3.05.0685 and technical documentation for instruments.

4.1.2.2 Smoke removal automation

1. Automation of the smoke removal system is implemented on the basis of ISO Orion, provided for in the fire alarm section (PS). The system, when receiving the "FIRE" signal, provides opening of smoke removal valves, starting of engines of the smoke removal system, opening of external air dampers.

2. Opening of smoke removal valves is performed:

- automatically, from fire alarm;

- remotely, from the C2000 console installed in switchboard;

- by local start-up from the button located near the valve.

- manual start-up from manual fire detectors installed on escape routes

3. Automatic opening of valves is carried out from the relay of the Signal20M devices provided in the section - PS, via the amplifier of contacts UKVK/05. The valve opening relay is activated when two or more fire detectors operate on one loop or two loops simultaneously on the floor where the operation occurred.

4. Start of engines of a system of smoke removal (SD1), opening of gates of external air is carried out from the relay of the S2000SP1 block, via the amplifier of contacts UKVK/05. The system is designed to block the start of engines and dampers if none of the smoke removal valves are open.

5. Smoke removal valves are started by short-term application of 220 V voltage to the valve electrical magnet. KVGngFRLS 4x1 cable laid horizontally in metal sleeve is used to power the starting circuit.

6. Start of engines of systems a subtime of air is carried out from the relay of the S2000SP1 block, via the amplifier of contacts UKVK/05. Valves of the air pressure system are started by short-term application of 220 V voltage to the valve electrical magnet. KVGngFRLS 4x1 cable laid horizontally in metal sleeve is used to power the starting circuit.

7. KPSeng (A) FRLS cables are used as signal cables. Low-voltage signal cables are laid to the horizontal conduit in the duct, along the vertical riser in PVC diam pipes. 50.

8. All connections shall be made in screw junction boxes or by soldering. Installation of instruments, actuators, wires and cables shall be carried out in compliance with applicable norms and requirements: SP 5.13130.2009, RD 78.14593 and PUE. Connect and configure the instruments according to the manufacturer's technical documentation.

9. When programming the system, the process loops of the valve opening alarm are combined into one section (for all valves). The valve start-up relay shall be connected to the corresponding fire alarm sections within one floor. Limit the duration of relay operation to the value required to actuate the valve.

The system is programmed from the computer by the programs PPROG.exe and UPROG.exe.

Grounding

Grounding of smoke removal system devices, power equipment, metal sheaths and cable screens shall be performed in accordance with Chapter 1.7 of PUE, GOST 46479 *.

Grounding and lightning protection issues are discussed in the electrical section of the project.
