The unit in the device of execution 3 works as a FACIE with the possibility of expanding the functions of the fire control device when the SCB block and other devices are connected by shielded two-wire information line.

            The unit in the device of execution 4 works as a FACIE and ensures:

• receiving reports of fire and malfunction detectors included in the thirty-two loops;
• ensures the issuance of a command by shielded two-wire information line for manual and automatic start of fire fighting, with the help of the unit SCB;
• ensures the issuance of a command by shielded two-wire information line for the termination, restoration and discharging of the start, with the help of the unit SCB;
• reception on the controlled duplex information line of information signals from the blocks "ALTO 2000 BCP";
• formation of alarms, malfunctions, disabling of ventilation;
• the inclusion of warning blocks ("FIRE!");
• light and sound indication of operating modes.

-        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:

• reception of messages from detectors connected directly to the loops of signaling (number of alarm loops is up to 32);
• the issuance of a fire alarm signal to the operator by light and sound signals indicating the number of the loop and filling in the alarm in the event log, issuing a fire alarm signal by closing the relay contact;
• issuing of a signal error to the light and sound signals operator indicating the number of the loop and filling in the failures in the event log, the issuance of a fault signal by closing the relay contact;
• the formation of the ventilation disabling signal in the automatic mode while the operation of two loops of the alarm, or when the manual start is activated;
• the light-control signal alert
• formation of a command for launching the SCB units, if the "AFFS" mode is allowed, the “Automatic mode” mode is automatically operated in two separate plugs of the block corresponding to one direction of fire extinguishing;
• formation of a command for manual start of SCB blocks in the manual and automatic fire extinguishing modes - by the operator command from the control panel of the block (by pressing the button of the corresponding zone under the cover, which bends);
• provides the issuance of an information command for the SCB blocks for the stop and restart startup by the operator from the control panel of the block by pressing the button "ON/OFF" on the shielded two-wire information line;
• provides an indication of the cease-start (LED "Delay Start");
• provides the issuance of an information team for the SCB blocks to the start disable of the SCB by the operator from the control panel of the block by pressing the "RESET" button on the shielded two-wire information line;
• the display of transmission, reception, confirmation of start-up from the corresponding SCB on the indicators of the control panel of the block;
• filling in the nonvolatile log of messages about all events and operator actions;
• automatic switch to standby power supply with indication of the power supply mode on the control panel;
• manual testing of indication bodies in the "CHECK" mode.
