Connecting Bpi Bus Devices - Bentel Security KYO 320 Installation Manual

About the Wiring Diagrams The locations of the ter -
minals in the wiring diagrams may be different to those
on the board.
Ø the Zone terminals may belong to the Control panel,
Keypads or Output Expanders;
Ø the Open-Collector Output terminals may belong to
the Control panel or Output Expanders;
Ø the Input zone and the Open-Collector Output termi -
nals (in the wiring diagrams) can be found on the
Main Unit or Expanders;
Ø only the terminals required for the connection are
shown in the wiring diagrams.

Connecting BPI Bus Devices

The BPI bus supports the following devices:
Ø up to 32 Keypads
Ø up to 32 Readers
Ø up to 32 Input Expanders
Ø up to 16 Output Expanders
Ø up to 8 Power stations
Ø up to 16 LED Keypads
Electrical Connections The BPI bus devices must be
connected in parallel to terminals [+], [C], [R], [–] on the
Main Unit, as shown in Fig. 11.
The Power Station has two groups of terminals for the
BPI bus connection: the BPI-IN group — for the Power
Station; and the BPI-OUT group — for the BPI devices
connected downstream of the Power Station.
The two groups of terminals are electrically isolated,
therefore, all the cables and devices connected down -
stream of the Power Station will not load the Control
panel BPI bus.
Refer to the Power Station Instructions leaflet for further
details.
+
Only one Power Station can be connected to each
shunt of the Control panel BPI bus (see Fig. 12).

INSTALLING
Dual Branch Bus The Control panel BPI bus has two
independent branches:
Branch 1 (BPI1) — terminals no. 51, 52, 53 and 54;
Branch 2 (BPI2) — terminals no. 55, 56, 57 and 58.
Each Branch is protected by its own fuse, therefore,
short-circuit on one branch will not impair the operating
capacity of the other.
+
The Outdoor Control panel BPI bus peripherals
should be connected to one Branch of the BPI bus,
and the Indoor peripherals to the other. In this way,
tamper on one branch will not impair the operating
capacity of the other.
Assigning Addresses You must assign an Address
to each of the BPI bus devices. The assigned Address
will allow the Control panel to distinguish one device
from another. The Peripheral devices are divided into
types: Keypads, Readers, Input Expanders, Output Ex-
panders and Power Stations.
Devices of the same type (e.g. two Readers) must
have different Addresses.
Devices of different types (e.g. a Keypad and a
Reader) are intrinsically different, therefore, may have
the same Address. The BPI bus peripheral Addresses
can be assigned in any order, using the DIP switches 80
(refer to Table 1).
+
Output Expanders have 4 DIP switches, and can be
assigned to Addresses no. 1 through no. 16 ONLY.
For the Address Combinations refer to the num -
bers in brackets in Table 1.
+
Refer to the Power Station Instructions leaflet, and
the keypads Instructions leaflet, for the Address
setup. Power Stations can be assigned to Addresses
no. 1 through no. 8 ONLY. The position of DIP
switch no. 1 in uninfluential.
Setting the BPI Level The BPI Level determines the
maximum voltage the BPI bus can carry. Some BPI de -
vices have 5V and 12V options.
