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
7.1
After transportation under conditions different from the operating
conditions, the BRA should be kept unpacked in the operating conditions
for at least 4 hours.
7.2 BRA registration into RPA (Extender)
1)
Connect RPA to Control Panel via RS-485 interface.
2)
Register the RPA in the Control Panel in accordance with the Instructions
for Astra-812 Pro or the Instructions built into the Configuration Module of the
PKM Astra Pro software.
3)
Connect the BRA to the power line (terminals "+", "-") and the infor-
mation line (terminals A and B) of the RPA, connect with the power off.
4)
Turn on the power of the RPA, BRA.
5)
Start the Registration mode of devices in the RPA on the Control
Panel using the command via the Astra Pro or Pconf-Pro PKM menu, or
the Astra-812 Pro Control Panel menu in accordance with the Instruc-
tions.
The mode takes 60 sec to register one device.
6)
Run the registration mode on the BRA by lighting the SLC indicator
from the bottom button of the Astra-942 laser remote control for at least 1
sec.
Attention!
Simultaneous launch of the registration procedure on several ad-
dress devices is prohibited.
7)
The registration test:
- in case of successful registration, the screen will display the
abbreviated name “BRA” or the message: “BRAxxx registered”,
- in case of unsuccessful registration, you must repeat the
registration
.
8)
After registration, the BRA indicators will display the current power and
load status in accordance with tables 2-5.
9)
BRA registration is completed.
7.3 Removing BRA from RPA memory.
Deleting of the BRA from the RPA memory is carried out through the
Configuration Module of the Astra Pro PKM software, or from the Astra-
812 Pro control panel menu.
7.4 BRA setting
7.4.1
Setting and changing the operating modes of the BRA is performed:
1) using PKM Astra Pro from the menu item of the Configuration Module
of PKM Astra Pro "Hardwired devices / List of addressable devices /
BRAs",
In the window "Setting the BRA" select the device type (Valve or Relay
unit) and set its parameters.
7.4.2
All BRA notification sources in the "Valve" and "Relay unit" modes
must be assigned to technological partitions (to monitor the status of
"Tampering", "Power failure", "Short circuit" or "Open circuit" of communi-
cation lines with the relay, etc.), see table 9 .
7.4.3
The number of
BRA’s notification sources and their purpose are pre-
sented in Table 9.

unit, on the System outputs/IU
, select “Valve status display” and assign
the valves to the IU LEDs.
8 Installation
8.1
Specialists who have studied this user guide and are allowed to work
with electrical installations up to 1000 V are allowed to work on the instal-
lation, maintenance and operation of the BRA.
8.2
Installation, mounting-dismantling should be carried out with the pow-
er supply of the BRA turned off.
8.3
BRA is installed on the walls or other structures of the protected
premises in places protected from the effects of precipitation, mechanical
damage and access by unauthorized persons.
8.4
When installing, it is allowed to use mounting devices (cabinets, box-
es, etc.)
8.5 Installation order
1
Remove the cover by unscrewing the 2 screws on the bottom end
surface of the BRA housing
2
Mark the mounting holes on the bearing surface along the base of
the BRA, mount the fasteners
3
Conduct wires from the power supply, interfaces
RS-485, SLC, BRA outputs through wire entry hole.
4
Fix the BRA on the bearing surface with screws
5
Conduct electrical installation to the output terminals of the BRA in
accordance with Table 1 and the wiring diagram (p.9)
6
Replace the cover, tighten two screws.
