2. Brief description of the protected object.

The object is a 2-story radio center building with an area of ​ ​ 878.4 m2.

All administrative premises shall be protected by automatic fire alarm except those specified in SP 5.13130.2009. Appendix A, item A.4.

4. Warning system for people in case of fire.

All floors of the building are equipped with a fire warning system in accordance with SP 3.13130.2009 "Fire protection systems. C-system of warning and management of evacuation of people in case of fire. Fire safety requirements, "

According to Table 1 and Table 2 (16-number of floors - up to 6) SP 3.13130.2009,

At this facility, a type 2 warning system is used, providing for the installation of:

- sirens;

- "OUTPUT" light indicators;

Sirens are attached at a height of at least 2.3 m from the floor level, the distance from the ceiling to the detector must be at least 150 mm.

On the escape routes, exits to the staircases, "EXIT" light indicators and escape direction indicators are installed, constantly connected to an uninterrupted power supply.

Monitoring of sounder lines is performed by UKMEDiP isp. IS

manufactured by Hephaestus LLC, St. Petersburg. Information on malfunction of the sound notification arrives on PPKOP of "Signal20P" located on the 2nd floor from which on the communication line arrives on the nakhodyashchiysyaa C2000M control panel in office No. 34 on the second floor.

Control of lines of light annunciators is exercised by block UKLSIP isp. IS

manufactured by Hephaestus LLC, St. Petersburg. Information about the failure of the light warning line is transmitted to the "Signal20P" PPKOP located on the 2nd floor, from which it is transmitted through the communication line to the "S2000M" control and monitoring panel located in room No. 34 on the second floor.

Power supply is provided from external power supply source 220V 50Hz (category 1 as per PUE). Backup power supply of devices is provided through BRP12 units, which have sealed unattended accumulators with voltage of 12V, capacity of 7 A * h. Storage capacity of accumulators provides operation of CO during 24 hours in standby mode ("Normal") and at least 3 hours in "Fire" mode (in accordance with para 4.3 of Sp 6.13130.2009).

5. Principle of operation.

When fire detectors are activated on the receiving equipment, an audible and light alarm is turned on, indicating the number of the loop (line) in which the activated detector is included.

In case of damage of trunk lines or loops with fire detectors (break, short circuit) on receiving equipment sound and light signal of damage with indication of number of damaged loopback is activated.

The sound signal in case of fire differs in tone from the sound signal about damage, malfunction.

Detailed description of the principle of operation of the receiving equipment and individual elements included in the plant is given in the technical documentation of the factory manufacturers.

6. Installation instructions.

Installation of alarm equipment shall be carried out in accordance with the approved design and estimate documentation or inspection certificate (in accordance with standard design solutions), working documentation (work execution project, technical documentation of manufacturers, process charts) and these rules.

Cable lines of fire alarm and fire warning systems shall be laid in accordance with para 4.13. SP 6.13130.2009. (cable lines of fire protection systems can not be laid together with other cables and wires in one conduit, pipe, bundle, closed channel of construction structure or on one tray)

According to item 4.1. SP 6.13130.2009 (Cable lines of fire protection systems shall be made with a fire-resistant cable with copper cores that do not spread combustion during group layout according to category A according to GOST R IEC 60332322 with low smoke and gas release (ngLSFR), or containing no halo genes (ngHFFR).

7. Equipment placement.

Equipment is placed in accordance with SP 5.13130.2009 "Fire protection systems. Fire alarm and fire extinguishing units are automatic. Design Codes and Regulations, "paragraph 13.14:

13.14.1 Acceptance control devices, control devices and other equipment shall be used in accordance with the requirements of state standards, technical documentation and taking into account climatic, mechanical, electromagnetic and other impacts in their places of placement, as well as if appropriate certificates are available.
