The main control device of the system is PC with installed AWS "Orion" software. 10, read for control of 10 devices ("S2000," "Signal20P," "S2000-4," etc.); at shutdown of network food of PEVM the system passes under management of the C2000 device.

The automatic system of the okhrannopozharny alarm system and the notification about the fire is intended for delivery of signals "Attention", "Fire" and "Malfunction" to personnel on duty to a post of the round-the-clock watch in the building of the temple, for transfer of a disturbing signal on PCN in the system of "Inflow" and formation of an impulse for management of the system of the sound and speech notification about the fire.

3.1 Organization of fire alarm system

3.1.1 Description of OPS units

The following equipment is provided in the design. Equipment of NVP "Bolid" company - address devices: fire safety control and monitoring panel "S2000," receiver-control device "Signal-20P SMD," receiver-control security device "S2000401," repeat RS485 interface with galvanic isolation "S2000PI."

Equipment of the company "System Sensor" - fire detector smoke-electronic "IP 21273" (Profi-O), fire detector thermal maximum-differential "IP 10131 A1R" (Profi-T), fire detector smoke linear "6500R," fire detector manual "WR2061SR" for remote control "KR,"

Equipment of other companies - security volume detector "Photon," security magnetic contact detector "IO1026."

3.1.2 Technical data of OPS units

Orion AWS software is installed on IBM compatible PC and runs Microsoft Windows 2000, Windows NT 4.0, Windows XP. Russified versions of OS data are desirable. Minimum requirements for PCMs: Pentium III 850, 128Mb RAM, SVGA 32Mb, 50GB on HDD, mouse, sound card, recommended monitor screen size from 19 to 21 inches.

The following Orion AWS software subsystems are involved in this project:

• "Operational task" - is intended for logging of events, control of security and removal from security of objects, monitoring and graphical display of the state of sections and zones of the object, voice warning in case of alarm situations.

• "Database Administrator" - is designed to manage the input, editing, sorting and exchange of data necessary for the correct operation of the security system.

• "Report Generator" - is designed to generate reports on the status and events of the hardware part of the integrated system at a user-defined time interval.

• "System Wizard" - designed to archive, restore, delete information entered into the system database.

• "Shleifes" - designed to display the state of loops in real time.

• "Plan Editor" - designed to draw plans of premises of security objects.

• components "Uprog," "Demonstrator" and "Configuration of C2000 console" - are designed to emulate the operation and configuration of devices.

Orion or the C2000 remote controller provides to PEVM with an automated workplace reception of signals, through the addressed devices "C2000", "Signal20P SMD", "C2000401" from automatic and tame announcers.

Simultaneous operation with PC devices with AWS "Orion" and "S2000" bullets is not possible, therefore redundancy is performed by switching over of devices control from PC to "S2000" panel at disconnection of PC. When the PC is restored, the control is rotated by the Orion AWS. For redundancy "C2000" panel operation mode is used, when it acts as RS232 - RS485 interface converter, if PC polls the devices, and if there is no interrogation within the specified time it goes into active state (starts working with the devices). Once the PC device poll is restored, the console returns to interface converter mode. When the console is in interface converter mode, any control of the instruments from this console is not possible. Also in this station, the console does not display information from connected devices, there is no access to the event buffer. When the console enters the active mode, its functions (instrument control, event log viewing, etc.) become available. Events that occurred in the system during operation of the panel with instruments will remain in the buffer of events of this panel and will not be subtracted by AWS "Orion" at restoration of PC operation.

To set the mode of interface converter with automatic switching to active mode in the panel, set the mode of panel operation as per RS232 ("MODE" parameter of "55 RS232" menu) to "PI/RESERVE." Besides, it is necessary to set a delay of transition to the active mode at loss of contact with the computer (BOCCT TIME parameter of the 55 RS232 menu). The delay can be in the range of 1-255 seconds, the recommended value is at least 60 seconds.

The system has an interface line, which is a two-wire communication line of the trunk structure with visual and audible indication of alarm and malfunction on the system devices.

The system generates the signal "Attention" at actuation of one detector in the fire loop and the signal "Fire" at actuation of the second detector in the same loop, as well as the signal "Fault" at short circuit or alarm loop break.

Fire alarm loops are connected to "Signal 20P SMD" device (designation on diagrams - ARK2). Distribution of firefighters:

Remote control panels "RTS451KEY" are designed for monitoring and remote testing of linear smoke detectors "6500R." On the front panel of the remote control panel there is a two-color LED indicator of green and red color and a test trigger.

3.2 Fire Warning Organization

Notification of people about the fire at the facility is carried out in the following ways: 1) Voice notification via 5 independent channels (jointly or separately) by broadcasting pre-recorded messages or by broadcasting messages of on-duty personnel through a microphone from a round-the-clock duty post in the temple building. 2) Sound warning by switching on the combined light-and-sound alert at the 24-hour duty station in the temple building. 3) Light warning by turning on "EXIT" wall signs on escape routes from the building.

3.2.1 Description of warning installations

KARAKElectronics equipment - a portable amplifier for 5 zones "TOWER 5200," equipped with an additional module of the CDplayer and radio receiver "KCR1000," is designed to broadcast voice messages and alert in emergency situations; wall speakers with attenuator "KPAWS10" and speakers of column type "KPAC020"; dynamic microphone "D6" with bracket "KMS10D."

1) Selection of translation zones: 1,2,3,4,5 or all together;

2) Automatic fire warning when connected to the fire alarm panel;

3) Attention signal generator (sirens);

4) 2-band equalizer for each input;

5) Built-in monitoring loudspeaker (1 W);

6) Support of the priority broadcast function;

3.2.2.2 Connection of loudspeakers

The alarm amplifier has an output of 100 V. This system involves the use of a large number of loudspeakers connected to one long loop. Output resistance of amplifier is calculated by formula:

, where 100 V. is the output voltage, 240 W. - output power of amplifier.

The overall loudspeaker line resistance shall not be lower than the amplifier output resistance. If the overall loudspeaker line resistance is lower than the amplifier resistance, this may cause the amplifier to overload and fail.

Wall speakers "KPAWS10" (10 W) due to the presence of an integrated attenuator, allow you to set one of four levels of sound volume; are connected to the line by contacts "COM" (Black) and "500 Ohm" (White).

Wall speakers of column type "KPAC020" (20 W) have input resistance - 500 ohms.

The total resistance of the loudspeaker lines is calculated according to the formula:

The total resistance of the loudspeaker lines for each translation area is:

1 zone (line) "KPAWS10" (2 pcs.) - R = 250 Ohm.;

2 zone (line) "KPAWS10" (2 pcs.) - R = 250 Ohm.;

3 zone (line) "KPAWS10" (3 pcs.) - R = 166.6 Ohm.;

4 zone (line) "KPAWS10" (3 pcs.) - R = 166.6 Ohm.;

5 zone (line) "KPAC020" (2 pcs.) - R = 250 Ohm.;
