The Wiring
The section describes how to wire the Main Unit, BPI
bus peripherals and various security devices.
Each wiring diagram refers to a specific type of device
(BPI bus devices, Detectors and Signalling devices).
+
Use shielded cable for all connections, with one
end connected to negative and the other floating.
!
The end of the stranded conductor must not be
soft soldered in places where it is subject to
contact pressure.
!
The Mains wiring must comply with the rules
for double or reinforced insulation.
+
Use an adhesive cable grip to secure the wires to
the terminal boards.
The wiring diagrams show some of the many tailored
solutions this system provides.
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 (16 for KYO 100)
Ø
up to 32 Readers (16 for KYO 100)
Ø
up to 32 Input Expanders (16 for KYO 100)
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. 13.
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. 14).
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.
