1 FUNCTION
1.1
BPA is designed for:
– control the communication line and managing devices of the alerting
system and control evacuation of people in case of fire;
– control and start of automation control cabinets (signals "Failure",
"Emergency", "Automatics disabled" and " smoke exhaust Fan (pump,
lock) activated);
– control and service fire automatics powered by 12 V or 24 V;
– transmission of signals through an intermediate relay device to the in-
puts of elevator controllers, voice alerting units, etc.);
– control through the built-in two AL (Zone 1 – Zone 4) of addressable
fire detectors, intrusion, technological devices (including those powered by
AL) and transmission of notifications via SLC through RPA to the Control
Panel.
1.2
BPA is designed to operate in SLC formed by RPA.
1.3
The number of BPAs registered in the Control Panel is up to
96 units.
1.4
BPA provides protection of control outputs
OUT1, OUT2
against
overloads, polarity reversal, voltage surges.
1.5
In the initial state, reverse polarity voltage is applied to the outputs of
the BPA, it is necessary to protect the connected load sensitive to polarity
from reverse voltage.
1.6
The outputs
OUT1, OUT2
can be operated with or without control
of the integrity of the line (depending on the configuration).
When outputs are operated with line
integrity
control
, it is necessary
to connect the
terminal elements
of the output from the delivery set to
the terminals
OUT1, OUT2
.
1.7
BPA provides:
a)
control of the power supply at the
inputs U1, GND, U2, "+", "-";
b)
switching the input voltage from 10.5 to 28.7 V from inputs U1, U2
to outputs
OUT1
and
OUT2
with switching current of each output up to
1.25 A
;
c)
control of the load line of the outputs
OUT1
and
OUT2
, separately
for open and short circuits, and transfer to the Control Panel infor-
mation about the integrity of the load line;
d)
control of the state of
4 alarm loops
of the following types: security, fire
thermal with double actuation, fire smoke with double actuation, fire com-
bined with single actuation and technological with short circuit (Open cir-
cuit) control;
e)
light indication of the BPA operation, the status of the outputs, SLC and
AL.
1.8
The power supply of the
address
part of the BPA is carried out
only
from the RPA via the SLC power line (terminals "
+
", "
-
").
1.9
The power supply of the
outputs and AL
of the part (outputs, AL)
is carried out
only
from an external power supply of 12 V or 24 V D.C.
1.10
The BPA has two independent power inputs (main and backup)
(terminals U1, GND, U2) and automatically switches from the main input to
the backup and back in case of a voltage drop or no voltage at one of the
inputs.
1.11
There is galvanic isolation between the address and signal-starting
parts. When powering the BPA and RPA from different power sources,
it is not allowed to combine their zeros, except for the case when the
BPA and RPA are powered from one set of main and backup power
sources.
1.12
The BPA provides operation with the length of the communica-
tion line of the
SLC
interface up to
1000 m.
1.13
Recommended wires for
SLC
: cable with two pairs of twisted
cores (pairs arranged in parallel), core cross section (single-wire class
1 or stranded at least class 3, from 0.35 to 2.5 sq. mm.
The recommended wire type to ensure maximum range for SLC in fire
systems is
FRLS (FRHF, FRLSLtx), 2×2×0.5.
For security systems, it is permissible to use a UTP 4
×2×0.5 cable.
