Mall Fire Alert

Purpose of the installation

In accordance with the requirements of the Set of Rules SP 3.13130.2009, a type 3 warning and evacuation control system (SOOE3) has been developed for the shopping center.

The developed EPSS system is an integral part of the complex of engineering systems for fire protection of the building and provides:

dividing the building into warning areas;

transmitting voice messages and special pre-recorded texts both to a separately selected zone, a group of zones, and to all zones simultaneously;

transmission of voice messages from remote microphone consoles, with the possibility of selecting translation zones;

provision of notification about evacuation of people with hearing impairment, by means of light stroboscopic annunciators;

the possibility of implementing several options for evacuation plans from each zone;

coordinated control from one fire department of the building systems ensuring safety of people in case of fire;

24-hour operation of all equipment and prompt transmission of voice messages about the occurrence of a fire, about escape routes, as well as about any emergency situations throughout the building;

possibility of operation in the mode of voice messages (announcements, instructions) broadcast via the EMSS network, as well as shutdown of this mode at reception of "FIRE" signal with switching to the fire warning mode according to the specified algorithm;

check of equipment serviceability and integrity of EPSS lines and circuits;

operation of the warning system in case of loss of main power supply (220V 50Hz) required for complete evacuation of people;

3. Technical solutions

The selection of equipment for the construction of the EMSS system was made on the basis of the requirements for the system. The fire warning and evacuation management system was designed using 600 series equipment from InterM (Korea).

Fire warning system includes:

Central equipment

- Alarm panel "EP616";

- Audio signal distributors "PE-606";

- Warning system controller "ECS616";

- Translation line control unit "SC624";

- Digital tape recorder "PV632A";

- 480W power amplifiers "PA648";

- 360Vt power amplifiers "PA636";

- Power amplifiers 240Vt "PA624";

Message Playback Equipment in Alert Areas

- Loudspeaker, 10 W, 90 dB, 15012000 Hz, "SWS10";

- Loudspeaker, 3 W, 89 dB, 18010000 Hz, "SWS03";

- Remote microphone console "RM616";

- Lightning annunciators "Light220";

Additional equipment

- Power supply units "PD659";

- Power expander "PD658";

- Charger "PB607";

- Batteries.

Central equipment is installed in 19 "equipment cabinets and is located in the security room on the 1st floor (pom. 112),. Power supply of the central equipment 220V 50Hz is provided according to the I category of power supply with redundancy. The use of redundant power supplies enables uninterrupted power supply of the central equipment when the main primary power supply of the sources (220 V 50Hz) disappears, due to the energy of the storage batteries.

In the security room on the 1st floor, install emergency lighting and provide artificial lighting of at least 150 lux for fluorescent lamps and at least 100 lux for incandescent lamps. Emergency lighting shall provide illumination on working surfaces of at least 10% of the corresponding standards. Provide measures excluding access of unauthorized persons to EMSS equipment.

Remote microphone consoles of the warning subsystem are installed in the administration room on the 1st floor.

Power supply of the peripheral equipment of the EPSS system is provided from the central equipment installed in the security room via communication lines.

Power supply of "EXIT" annunciator is performed from emergency lighting panel.

In the premises of the building, voice annunciators are installed, according to the drawings, and are connected to the power warning lines provided by the drawings. The alert lines are connected to the amplifiers at 100V terminals.

4. System operation

The warning subsystem is started automatically by the signal of the automatic fire alarm system, according to the algorithm programmed in it.

Signals of automatic warning start from the automatic control system are transmitted to ECS1 unit inputs. The system controller controls the activation of alert lines and the operation of translation amplifiers. The algorithm of automatic warning start is determined during programming of automatic fire alarm system operation.

In the case of manual notification, as well as voice messages, in the voice message transmission line (out of 11 possible), the operator selects by pressing the corresponding buttons on the microphone consoles RM1.

5. Electrical wiring.

Installation of EMSS warning lines is carried out by open laying method, with the condition of their integrity monitoring along the entire length. Connections and branches of wires and cables are made in junction or junction boxes by soldering or by means of screws.

The distribution network of the warning system is made by the VBGngFRLS cable in PVC pipes rigid along the walls and floors (as per drawings).

Switching between EMSS central equipment devices is performed by different types of cables, as per drawings, as well as cables included in the equipment supply package.

Vertical laying of cables and wires of the ECSS system, between floors, is provided in a low-current riser made of two PVC pipes with smooth rigid dy = 63 mm.

6. Power supply and grounding (connection)

According to the degree of reliability of the power supply, automatic fire protection units are consumers of reliability category I and must be provided with electricity from two independent mutually redundant power supplies, and their power supply interruption in case of power supply failure from one of the power supplies can be allowed only for the time of automatic power recovery.

If there is one power supply, it is allowed to use fire protection units, storage batteries or uninterruptible power supply units as a backup power supply source, which must provide power to the specified electric receivers in standby mode for 24 hours and in "Alarm" mode for at least 3 hours.

Power supply of light stroboscopic annunciators is provided with project 04511APM, with a constant voltage of 24B, with reservation.

Grounding (boring) of equipment shall be performed in accordance with "Electrical Installation Rules," seventh edition (PUE); SNiP 3.05.068 "Electrical Devices"; requirements of GOST 12.1.03087, and technical documentation of manufacturers of components. Protective grounding (ground) resistance must be not more than 4.0 Ohm.

All metal parts of electrical equipment that are not normally energized, but which may be energized due to insulation failure, shall be grounded (grounded).

Power supply of the central equipment of the EMSS system (devices located in the hardware cabinets 19 ") 220V 50Hz is performed by cables included in the equipment supply set, from plug sockets of the distribution and separation power system connected according to the I category of reliability of power supply.

The following devices of the EMSS system are subject to grounding (earthing):

- metal housings of the ESMS central equipment located in the hardware cabinets in the security room;

- 19 "metal equipment cabinets located in the security room;

Grounding of the hardware cabinets 19 "and the housings of the equipment installed in them should be performed by a separate cable from the grounding bus of the power panel (performed by the section of internal electrical networks). Connect the equipment rack and housings of ESDS equipment to the grounding bar by bolting.
