BVV-A–02-02

Addressable input / output unit
(fire extinguishing system unit)

The BVV-A-02-02 address input-output block is intended for:

inclusion in the addressable fire extinguishing system of non-addressable components (BКN blocks) produced by ALC"SCB "ELECTRONMASH" and displaying their general condition on the receiving and control fire address device (PPKP-A) or information panel (IT);
connection to it of four load control units (BKN) via the RS485 interface;
control and transmission of the general states of the BKN blocks in the address loop of signaling;
setting the type of signaling loop (SL) of BKN blocks.

Technical characteristics:

Own current consumption of the block from the power station (not at the time of transfer to the power station), ?A, no more than 300;
Informativeness of the block (number of types of messages) is not less than 8 channels.
The status information transmitted to the system is common for each BKN block: "Blocking", "Automatic", "Attention", "Fire", "Activation", "Start" (exit of the fire extinguishing agent), "Malfunction", "Shutdown".
The block allows you to manually set your address in the range from 129 to 168 in binary code by setting jumpers аnd adding their values ?? from the number 128.
The current state of the block settings is stored in the non-volatile memory.
The number of indicators of the block - 8 (designation of indicators: "Status", "Fire", "Start", "Fault", "1", "2", "3", "4").
The time of technical readiness is no more than 30 seconds, provided that the signaling loop are present.
The term of service is not less than 10 years.
Overall dimensions of the block, mm, no more than 91/71/35.
Mass of the block, kg, no more than 0.2.
