Wiring
The section describes how to wire the Control Panel,
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
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,
the Keypads or the Input/Output Expanders;
Ø
The Output terminals may belong to the Control
Panel or the Input/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
LCD Keypads
Ø
Touch Keypads
Ø
Key Readers
Ø
Input Expanders
Ø
Output Expanders
Ø
Power stations
The maximum number of devices supported depends on
the type of control panel, as shown in Table 1 on page 6.
Electrical Connections
The BPI bus devices must be
connected in parallel to terminals [+], [C], [R], [–] on the
Main Unit, as shown in Figure 9.
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. 10).
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 an-
other. The Peripheral devices are divided into types:
Keypads, Readers, Input/Output Expanders 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 as-
signed in any order.
Table 5 shows the configuration of microswitches for the
assignment of addresses to the Input/Output Expansions,
the Readers, and the Power Feeding Stations: read the
keypads’ instructions in order to set their address.
