3. Key Technical Solutions

3.1 General provisions

The designed warning system is based on equipment manufactured by Wheelock inc. (USA) and Omega Sound LLC (St. Petersburg).

The system architecture requires local and centralized system management.

The Omega SP40/2 panel is used as a local control device, which is responsible for notifying people in the premises of building No. 1. To increase the audio output power, the Omega SPB160 amplifier is used. Omega SP40/2, Omega SPB 160 is supposed to be installed in the room of the Dean's Office on the second floor of building No. 1 (pom. 27, see fig. 0311006CO04). In this case, the control of the system is carried out by the responsible personnel from the dean's office (transmission of "live" messages by means of an integrated microphone to correct evacuation routes ).

Monitoring and centralized control of the local Omega SP40/2 panel installed in the building No. 1 (later in other buildings) is carried out using the Omega SP4S console located in the temporary room of the security post (building No. 2, its transfer and reconstruction in the reconstruction plan for 2007 year) with a 24-hour stay of duty personnel. The responsible duty station has the ability to effectively monitor and control the entire system (transmission of live messages via the built-in microphone, activation of voice messages recorded in the memory of the Omega SP40/2 panel).

Also, the designed CO provides for the ability to transfer information voice messages through phones connected to the PBX of the CGP, background music, various programs, training calls to selected broadcast areas. The premises of building No. 1 are divided into three broadcasting zones:

1) office premises;

2) halls, corridors;

3) training rooms.

Selection of areas for background music broadcasting is carried out at the stage of commissioning and can be adjusted by responsible personnel during subsequent operation of the system. The source of background music, programs, training calls is the use of existing customer equipment. The area paging functions are controlled by the SP4TZC, the address area splitter SP4APS.

3.2 Organization of warning of people in case of fire

In the premises of the facility, a type 3 warning and evacuation control system is provided (in accordance with item 8 of Table 2 of NPB 10403).

In accordance with this type of EPSS, the project provides a voice method of notification. The "Exit" annunciators are considered in the design for the reconstruction of the fire alarm system of building No. 1.

Fire warning area - 1 (simultaneous notification in all rooms of building No. 1).

This project provides for the installation of voice alerts in all places of permanent and temporary stay of people.

Sound level of information from voice annunciators is not less than 15 dBA higher than permissible sound level of constant noise in the protected room. Standard sound levels of constant noise - in accordance with GOST 12.1.03681. The calculation of the number and power of activation of the annunciators is based on the procedure presented by Wheelock inc. (OSCal _ Speaker (ver3) calculation program, located on the manufacturer's website at http://www.wheelock.ru/soft_spec/oscal_speaker%20 (ver3) .rar). Alerts do not have volume controls.

The Omega SP40/2 panel is adopted as the local alert control. An increase in audio output power is provided by the Omega SPB160 amplifier. Omega SP40/2 is a multifunctional controlled system designed for voice and light warning in emergency situations, announcements and background music. The SP40/2 control panel has a built-in 40W audio power amplifier and output 2A to power the light warning circuit and actuators with voltage = 24V. The SP40/2 is standard equipped with a built-in digital message module (3 messages with a total duration of 57 seconds), a manual microphone, a power supply and a battery charger for a backup power supply. SP40/2 performs full monitoring with self-diagnostics on faults:

- lines of light and voice annunciators - for short circuit, circuit break, ground fault;

- manual microphone - for connection or termination of the circuit;

- amplifier - for operation;

- digital module - for operation and integrity of messages;

- built-in power supply and charger - for input voltage and charging of batteries.

The Omega SPB160 provides additional audio power expansion to the SP40/2 panels. SPB160 consists of a 160W amplifier with two outputs of 80W each. The amplifier also performs monitoring with self-diagnostics of all internal units.

The SP4S console is used to centrally manage and diagnose the entire system. SP4S includes SP4-M, SP4A modules. The console allows to perform:

- selection of fire warning areas (s) (the number of zones corresponds to the number of Omega SP40/2 panels) and delivery of live messages to the selected zone (s) through the operator's built-in microphone;

- remote start of messages recorded in Omega SP40/2 digital memory (SP4A unit).

The panel provides:

- monitoring of the status of Omega SP40/2 panels with the output of fault information, activation;

- amplification and retransmission of civil defense warning texts (signals) to all warning panels simultaneously;

- protection against unauthorized actuation by means of an installed lock allowing operation through the operator's microphone;

- in case of simultaneous reception of signals of HHF and operator's microphone, the microphone has higher priority.

STB4 annunciators - wall version, STC8 - ceiling version are selected as voice annunciators. For the installation of ceiling annunciators, a dust-moisture-proof cap CBB8 is used. These annunciators have the ability to select the voltage of the alert line and the power on. The alarm line voltage is 70V. Quantity and installation sites and also inclusion power see fig. 0311006CO03...07.

Designed equipment designed to alert people about a fire has valid fire safety certificates.

Start of voice fire warning system in all protected rooms of housing No. 1 in case of alarm events (fire, fire threat) can be performed automatically (from actuators of existing fire alarm system, activation of IN1, IN2, IN3 SP40/2 inputs with corresponding priorities)semiautomatic mode (when the dispatcher operates when receiving command pulse from automatic fire alarm units using SP4A unit, which is part of SP4S console) and manual mode (live text transmission using the built-in microphone from both the Omega SP40/2 panel and the SP4S console).

The solution for interfacing with the fire alarm system for CO operation in automatic mode will be considered in the project for reconstruction of the fire alarm system of building No. 1.

3.3 Organization of information messages, background music, training calls/signals

The project provides for the organization of a system for broadcasting information messages, background music, sending training calls, using the resources of the designed fire warning system. In addition, the area telephone controller SP4-TZC and the address zone splitter SP4APS are used. The local application of SP4APS and SP4TZC allows you to complete the transmission of informational voice messages to the selected zones and transfer background music to the selected zones. The SP4TZC controls selective paging and background music functions via the RS485 interface. To amplify the audio signal from the output of the SP4TZC, the PRM150 unit is used with the ability to adjust the level. The SP4TZC, PRM-150 controller is to be installed in the TSO and St room located on the third floor of building No. 2.

According to the technical assignment, the rooms of building No. 1 in terms of functional purpose are divided into three translation zones.

The individual translation area refers to one of the individual outputs of the SP4APS splitter. The project provides for the organization of four individual broadcasting zones:

1) Office premises;

2) Halls, corridors 24, tech. floors;

3) Hall, corridors of the 1st floor;

4) Training rooms.

The software supplied with the SP4TZC will logically combine the individual translation zones. In our case, individual zones No. 2.3 are subject to unification in order to meet the requirements of the TA.

Information messages are sent to the selected translation zones (paging) from dial tone telephones connected to the PBX of the CGP and having pre-access to the paging port of the PBX. Translation area access codes are defined at the commissioning stage. The presence of a paging port in the PBX, as well as the communication links between the PBX and SP4TZC are provided by the existing ones.

The selection of zones for background music broadcasting and training calls is carried out using the application software of the SP4TZC controller. The source of background music, training calls/signals is the customer's equipment. The requirement for this equipment is the presence of an audio output with a level of 300mV (rms) (the input impedance of the BGM input SP4TZC is 600 ohms).

The equipment used allows you to adjust the sound volume of both information messages (paging) and background music.
