1 Function
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: electro-
mechanical 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 trans-
ferring 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 algo-
rithms,
"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 su-
pervision (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!

6.3 «Valve»operating mode
6.3.1 “Valve” operating mode BRA:
1) controls the condition of the valve limit switches via AL1 иAL2
(+Zone1- and +Zone2-)
2) if the control of limit switches is not configured, then the BRA deter-
mines the position of the valve according to the state of the outputs РАБ
and ИСХ;
3) BRA through its AL (terminal TST) controls the state of the TEST but-
ton. According to the status of the alarm loop, the BRA generates a con-
trol impulse to transfer / return the valve to the working / initial state for
local control (operability check);
4) The BRA stores the current state of the valve, limit switches, the TEST
button, the state of the outputs РАБ and ИСХ, the state of the power
inputs L1 and L2 and, based on this information, generates control com-
mands to display the state on its own built-in indicators.
6.3.2 In the “Valve” mode, the BRA has no system outputs.
6.3.3 In the “Valve” operating mode, 3 types of loops are available for selec-
tion:
- «Limit switch closed»,
- «Limit switch open»,
- «Limit switch not active» (no limit switch control).

Note
1 When setting up, select the type of AL2, which is the opposite in mean-
ing to that selected for AL1 (if the type "Limit switch closed" is selected for
AL1, then the type "Limit switch is open" must be selected for AL2).
2 The determination of the state of the valve is always carried out by the
state of the two limit switches. Therefore, the setting should provide for
the use of only two limit switches at the same time, the limit switches
cannot be used separately.

6.4 Mode «Relay unit»
6.4.1 In the "Relay unit" mode, the BRA is one power relay output: (ter-
minals РАБ and ИСХ)
- open (off) –no 220 V power supply to the load;
- closed (on) –there is 220 V power supply to the load from one of the
power supply input lines L1 or L2 (with the ability to configure control of
load communication lines).
Notice - In the "Relay unit" operating mode, loops are not available The
tactics of the system output of the BRA is selected from the list offered in
the Configuration Module of the PKM Astra Pro software.
7 Preparing for operating and set up

10 Test
Testing is taking place with one of two ways:
1 way –using button TEST which is connected to the TST terminal:
- set the TEST button to the “Violated” state (press or release depending
on the type and setting of the BRA);
- visually control the transition of the valve to the РАБ (operation) state,
then to ИСХ (initial);
- control the state of the valve in Astra Pro PKM (Astra-812 Pro Control
Panel, Astra-814 Pro keypad): after the test is completed, the status is
displayed as “Valve in the initial state”, which means that the equipment is
configured correctly. Otherwise, the status is displayed as “Failure” and
the BRA settings need to be adjusted.
2 way - using Astra-942:
-light up the SLC indicator of the BRA from the top button of the left side
for at least 1 sec;
- the test is performed in the same way as described in the first method.
If during the test execution the BRA receives a command from the control
panel, then the test execution is terminated, the new state “Transition to
...” is assigned to the valve state, the control panel generates the “Valve
test completed” event, and the BRA executes the command from the
control panel.
