The block "ALTO 2000 BKP" is designed for operation in the device performance 1, 2 and 4 according to TS 31.6-16307479-001: 2006. The block operating modes in all performances are as following:

• rest mode;
• fire alarm mode;
• fault warning mode;
• disconnect mode (Applicable only during regular maintenance work);
• disable programming mode (Applicable only when performing maintenance work);
• log view mode;
• light and sound indication test mode;
• date setting mode;
• start mode.

The block in the device of execution of 1 and 2 works as an autonomous fire control unit with functions of the FACIE and ensures:

• receiving reports of fire and malfunction detectors included in the two loops;
• manual and automatic launch of fire extinguishing methods;
• block, reset, and discharge of the startup;
• forming of alarm signals, errors, disabling of ventilation;
• the inclusion of warning blocks ("GAS, CARE!", "GAS, DO NOT ENTER", etc.);
• light and sound indication of operating modes;
• the issuance of a starting impulse with a nominal current of up to 0.8 A for each of the four starting lines (execution device 1);
• the issuance of a starting impulse with a nominal current of up to 10 A for each of the four starting lines from the ISCAU appliance, which is included (execution device 2).

           The block in the device of execution 4 works as a fire control device with the functions of the control panel and ensures:

• the reception of fire notifications and errors from detectors connected within two ADC;
• manual and automatic launch of fire extinguishing;
• stop, reset and discharge of the launch;
• forming of alarm signals, errors, disabling of ventilation;
• the inclusion of warning blocks ("GAS, CARE!", "GAS, DO NOT ENTER", etc.).;
• light and sound indication of operating modes;
• the issuance of the trigger pulse with a nominal current of up to 10 A for each of the four launching lines from the ISCAU device, which is incleded (device in execution 4);
• the transmission of information signals, concerning the main modes of operation, fire, errors, automatic and manual launch to the "ALTO 2000 SCB" block by the controlled two-wire information line;
• the reception of control signals from the "ALTO 2000 CPU" block by the controlled two-wire information line.

              Intended use       

The scope of application consists in protection of industrial objects premises, banks, warehouses, underground and aboveground garages, tunnels, residential and administrative buildings, as well as other objects, on which, the conditions of blocks usage are constructive.

Functional features of the block:

• the reception of messages from sensors or from external FACIE, connected directly with the alarm detection circuit (number of ADC - 2);
• the issuing of a signal of fire alarm with light and sound signals indicating the loop number;
• issuing a fire alarm signal by closing the contact of the relay at the trigger of one alarm signal, or by turning on the manual launch;
• the issuing of a signal of error with light and sound signals indicating the number of the loop;
• the issuing of a signal of error by closing the contact of the corresponding relay in the event of at least one failure;
• the formation of a signal to shut down the ventilation in the automatic mode when the two loops of the alarm system are triggered, or when the manual launch is activated;
• forming a 30 second warning signal about the upcoming lauch;
• formation of a signal of a fire alarm lauch;
• automatic launch;
• manual launch when press a button under the hood on the control panel;
• manual launch when the button is pressed on the remote manual launch device;
• on and off launch by the operator from the control panel of the block by pressing the "OFF/ONN START" button;
• the operator resets the launch from the control panel by the button "RESET START" ”;
• the formation of the impulse of the starting current;
• turning on and off the AFFS mode with the help of a jumper;
• MANUAL / AUTO mode switching using the remote changer;
• the display of the start mode, stop and resert of launch, the launch circle, the volume of extinguishing substance release, the state of power supply and operating modes (manual, automatic, AFFS) on the control panel sensors;
• formation and transmission of information signals using the RS-485 communication module to the "ALTO 2000 CU" block;
• automatic switching to standby power supply with indication of the power supply mode on the control panel;
• manual testing of indication in the "CHECK" mode.
