- protection against false actuations by automatic reset of detectors fed via a loop;

- connection of address detectors;

- measurement of dust, smoke and temperature values and graphical display of statistics on the monitor of the Automated Workplace (AWS);

- a set of statistics for the development of measures to improve fire safety, organization of maintenance;

- visual display on the plans of the premises for the location of detectors and devices, the most smoky detectors, temperature in controlled points, statistics for the day, for the month, for the year;

- check of serviceability of starting circuits for break and short circuit;

- transfer of office and disturbing messages on the C2000M control panel, with further transfer to "ORION the missile defense".

3.2.System composition

The composition of the system is as follows:

- address controllers of two-wire notification transmission subsystem "S2000KDL";

- address-analog smoke detectors "DIP34A";

- address tame fire announcers of "IPR5133A";

- address relay S2000SP2 blocks;

- RS232/RS485 interface converters with galvanic isolation "S2000PI";

- standby power supplies "RIP24."

Conclusion of signals of all alarm systems and information on operation of loops of the fire alarm it is brought to the C2000M control panel, with further information transfer on the automated automated workplace workplace ORION located on the first floor at a protection post.

As the reception and control device the panel of control and control of "C2000M" is used.

3.3.BASS equipment main functions

- monitoring of up to 127 devices connected to the console via RS485 interface;

- display of events occurring in the system on the liquid crystal indicator, storage of the event archive;

- alarm signaling on the built-in audio annunciator;

- control of taking/removal and monitoring of alarm loops condition from the panel;

-programming of devices configuration;

- restricting access to control functions and programming using passwords.

3.3.2.S2000KDL - controller of two-wire communication line provides:

- power supply of connected address devices via two-wire communication line;

- work with adresnoanalogovy smoke announcers of DIP-34A:

- setting of "Warning" pre-warning threshold and "Fire" threshold;

- setting of time zones "Day" and "Night" with assignment of thresholds "Attention" and "Fire" separately for each time zone;

- dusty level designation;

- transmission of notices "Maintenance required," "Attention," "Fire," "Fault."

- connection of the address tame fire announcer of IPR5133A;

- control of actuation mechanisms via the address relay S2000SP2 block;
