Brief description of the object

3.1. Protected rooms are located on the attic of a four-story building with a basement and a technical floor. Brick building. The mansard is made of light metal structures. Fire resistance degree -II. Plenum ventilation. The rooms are equipped with suspended ceilings. Duty is carried out around the clock.

Key Solutions

4.1. Automatic fire alarm is made on the basis of PPKOP "VERSPK16," installed in the security room on the 1st floor.

4.2. In the premises to be protected, automatic fire detectors optoelectronic smoke "IP 21245" are installed. Detectors are installed on the suspended ceiling and the main ceiling in the dam space with separate loops. For maintenance of detectors installed behind the suspended ceiling, removable tiles of the Armstrong suspended ceiling are used.

For visual monitoring of the condition of the detectors installed behind the suspended ceiling, remote optical signalling devices "VUOSK" are provided (installed next to the detectors on the suspended ceiling). At the evacuation exits, manual fire detectors "IPRKsu" are installed. At the end of fire alarm loops, "UKSH1" loop monitoring devices are installed on the walls at a height of 1.52 m from the floor level.

4.3. According to NPB10403, the protected premises are to be equipped with a warning and evacuation control system for people in case of fire - the third type, consisting of "EXIT" "Lightning 12" light annunciators, "Mayak12K" light and "ORPHEY" voice warning system. The system of the speech notification ORPHEUS consists of the block of the speech notification (BSN) and acoustic modules "AM isp. 1 "(AM) ceiling unit. BRO voice warning unit is installed in the mansard corridor at the level of 2.2m.

The project provides for:

- Activation of fire warning system on attic floor from existing fire alarm;

- Actuation of the existing fire warning system in case of fire alarm on the attic floor;

- Serviceability check of warning lines (LO) and AM.

4.4. When one fire detector is activated in the loop, the device enters the "attention" mode.

When two fire detectors operate in the loop (fire occurrence in one of the protected rooms), the device sets to "fire" mode, the fire warning system for people and the ventilation shutdown and elevator control relay UK1UK4 "UK-VK/02" are activated. Matching of ventilation shutdown signal in case of fire with ventilation control automation is considered in section EM (Volume 5.1.2).

When the alarm loop is broken or short-circuited, the device enters the "fault" mode.

4.5. Installation of loops with automatic and tame fire announcers is carried out by a cable - KPSVVng-LS 1х2х0.5 in nonflammable PVC a corrugated pipe and nonflammable PVC a box taking into account requirements of NPB 882001 * and RD78.14593.

4.6. Installation of the warning system of people about the fire is carried out by a cable - KPSVVngLS 1х2х0.75 in nonflammable PVC to a corrugated pipe taking into account requirements of NPB 882001 *, NPB 10403 and RD78.14593.

4.7. Change of configuration of PPKOP "VERSPK16" to "Firefighter":

- Turn off the power supply of the device;

- Open the device cover;

- Set J1J3 configuration jumpers to OFF position on board attached to cover;

- Close the device cover;

- Switch on the power supply of the device;

- Perform "Test" (see Operating Manual).

4.8. Calibration of "VERS-PK16" PCCP:

- All fire alarm loops shall be connected to PPKOP according to the connection diagram;

- press the button of the 1st loop and do not release the button to supply power to the device - the device will enter the current calibration mode. At the end of calibration, the LED of the first channel will light up in red;

- after calibration it is necessary to remove power from the device. The device is ready for operation.

4.9. BRO programming. Connect one acoustic module to terminals "M1" and "O1," and 8.2 ohm resistor from the delivery set to terminals "M2" and "O1." To connect all general terminals of blocks "O1 O15" among themselves crossing points.

4.9.1. To enter programming, you must:

- remove jumper P1 (located on BRO board);

- for recording from built-in microphone set jumper P2 to position 1-2 (located on BRO board);

- connect button with normally open contacts to terminals "K3" and "General" (further - "TEST" button);

- connect the built-in accumulator to "Akk +" and "General" terminals in compliance with polarity - it is not allowed to connect the main power supply first, and then the accumulator;

- during 3 about a faltering luminescence of VKL and AWAR indicators signals about readiness for installation of parameters, the faltering luminescence of the OPOV indicator demonstrates that check of integrity of the Leningrad Region and AM is included;

- make sure that there is continuous illumination of "ON" indicator (BRO is in standby mode).

4.9.2. Erase messages from memory (complete cleanup).

- During erasure, all previously recorded messages, time delays are cleared from memory and LO monitoring mode is started.

- If the memory is clear, the attempt to erase again is ignored.

- To enter erasure procedure press S1 control button 4-5 times (located on BRO board) for approximately 2-3 s:

- Continuous glow of "AVAR" indicator during (10 ± 2) sec will indicate normal erasure procedure;

- After return of the AVAR indicator to a condition of a faltering luminescence, BRO it is ready to record of new messages.

4.9.3. To record a message from a microphone:

- Press S1 control button and hold it in pressed state to wait for "OPOV" yellow indicator to start recording;

- Intermittent illumination of "OPOV" indicator in this mode indicates overflow of memory;

- Hold S1 in the pressed state, at continuous illumination of the "OPOV" indicator, from a distance of 1520 cm from the microphone, deliver a pre-prepared message. The AVAR indicator at the same time plays a role of a signaling device of an overload and has to flash quickly according to voice loudness peaks, but should not shine continuously;

- The message should be concise, contain the direction of the escape route, for example: "Fire alarm, everyone urgently leave the building";

- When the message recording is finished, release S1 button;

4.9.4. Checking memory messages:

- Press "TEST" button 1 time for not more than 4 s;

- After 4 s from the moment of pressing the indicator "OPOV" (yellow) is activated and the message playback starts, intermittent illumination of yellow indicator in this mode indicates absence of message in memory;

- the message will be reproduced cyclically, with pauses between the end and the beginning of the cycle no more than 2 s;

- To stop playback press "TEST" button and hold the button pressed until "OPOV" indicator stops illuminating;

- After the recording procedure, shut down the system by disconnecting the terminal of the built-in accumulator;

- Disable "TEST" button and AM button.

4.9.5. After programming, install jumpers P1 and P2 in accordance with the required warning mode on the aircraft:

- jumpers P1 must be installed at actuation of warning from contacts "K1";

- jumper P2 must be set to position 2 - 3;

- Connect BRO to LO.
