Astra-BRA

1.1 BRA is designed to control smoke ventilation dampers, fire dampers of general ventilation, deluge dampers and other actuators powered by 220 V.
The BRA is designed to operate in the SLC formed by the RPA.

1.2 BRA provides:
- possibility to control the damper of fire dampers of types: electromechanical with return spring, reversible, electromagnetic by command of the Control Panel received via SLC;
- monitoring the load of the relay for open and short circuits and transferring information about the integrity of the load line to the Control Panel;
- valve position control by limit switches;
- LED indication of BRA operation, valve status, outputs and SLC;
- Valve test

1.3 The BRA can operate in two modes:
- “Valve” mode, in which the BRA implements special valve control algorithms,
- "Relay unit" mode, in which the BRA provides operation
- one relay output with load circuit control.
In both modes, the BRA can operate with or without load continuity supervision (depending on configuration)

1.4 The sources of notifications for the BRA are partitions of the Control Panel.

1.5 BRA can only be controlled by one Control Panel.

1.6 BRA provides configuring of operating modes using the menu of the PKM Astra Pro configuration module.

1.7 The BRA (signal part) is powered from the SLC power line (terminals "+" and "-"), the power part (L1, N, L2) - from the 220 V AC network.

1.8 The power supply of the power part of the BRA (relay, AL) is carried out from the main (terminals L1, N) and backup (terminals L2, N) 220 V power supplies. In the absence of the main power supply, the BRA automatically switches to the backup; when the main power is restored - switches to the main power.

Attention!
ONLY 1 AND THE SAME PHASE CAN BE SUPPLIED TO INPUTS L1
AND L2! SUPPLY OF DIFFERENT PHASES IS FORBIDDEN!
