3. MAIN TECHNICAL SOLUTIONS ADOPTED IN THE PROJECT.

Purpose of the system

The designed complex of technical security equipment (PSTC) of the facility is designed to:

to detect and record the occurrence of fire in the room;

for automated notification of people in case of fire at the facility;

to monitor the situation and prevent unauthorized entry into the facility and premises;

to maintain a log of events and write them to memory;

to control the performance of security services.

The PSTC provides the possibility to solve the following tasks:

protection of equipment and material assets in the building;

implementation of necessary measures to protect the life and health of persons in the premises of the building in case of emergency.

Short description of PSTC elements, proposed scheme and tactics of facility security

The PSTC installed structurally consists of several

related elements:

- security alarm system;

- fire alarm system (ATP);

- fire warning system for people;

- access control system (ACS).

Control and control of PSTC elements is performed at the security post (ground floor of the main building in the security room):

- from the device of acceptance and control PPKOP "Frontier 073";

- at the automated workstation of AWS "Intelligence"

For this purpose, PPKOP "Border-07-" is installed in the premises of the security post

3 "(BSP) and a computer with a set of programs of an automated workstation (AWS) configured in it.

PSK OP 010592501 "Frontier 073" monitors and controls all PSTC elements through connected line units (LB) and network devices (NS).

Using line units (LB), fire alarm loops (SH) are monitored and controlled.

Linear units LB06 carry out:

• reception of electrical alarm messages from detectors with normally closed contacts;

• monitoring of alarm loops serviceability with automatic detection of short circuit or bypass;

• transmission of signaling loops (SH) status information to the communication link (LS).

Each LB06 receives information from 4 (four) security SGs.

Linear units LB07 are designed for:

• reception of electrical alarm messages from automatic and manual fire detectors with normally closed and normally open contacts, from active fire detectors with non-contact action by two-wire SGs;

• SB serviceability check with automatic detection of a break and short circuit;

• transmission of information on the state of the FS to the communication line with the MSC.

Each LB07 receives information from 4 (four) SB firefighters.

The communication line of the LAN LB is laid in a linear-radial way with branches in the places of main line crossings along the vertical and horizontal lines .

Relay address unit BRA034 is used for:

• reception of control signals from the central processing unit;

• control of actuating actuators.

ARB has 4 (four) control outputs. In the designed system, this device controls the devices of the object warning system.

Redundant power supplies are designed for:

• 12V power supply to safety system consumers.

Power supplies have 1 (one) 12V or 24V power output. Power supply reserve of sources at loss of 220V network is performed using batteries installed in RIP compartments or in boxes.
