Connecting peripherals

The I-BUS line wiring
The SmartLiving peripherals (keypads, readers, expansions, sounderflashers,
transceivers, isolators and GSM communicator) must be connected to the control panel
via the I-BUS.
The connection between the control panel and its peripherals is achieved through a 4
wire (or more) cable.
ATTENTION!
The shield must be connected to one of the terminals (Negative or GND) at the
control panel end only, and must run along the BUS without being connected to
negative or GND at any other point.
The cable specifications depend on the length of the BUS (from the panel terminals to
the most distant point), Baud rate and the load current draw.
The connection with the control panel is achieved through terminals “+ D S -” on the
motherboard (Table 2-9: Mother board - terminal board, 6-7-8-9) of all models except
SmartLiving 1050/G3, 1050L/G3 and 10100L/G3 for which you must use terminals “+
D S -” on the LIVPWR100 board (Table 2-10: LIVPWR100 board - terminal board, 1-2-
3-4).
The maximum wire length of the I-BUS depends on the deployment of the peripherals
connected to the line and their specific current draw (in particular the keypads and
expansion boards). The power to peripherals and detectors can be supplied by external
power stations or by the line itself.
Furthermore, the speed of the communication BUS (Baud rate) can be modified by
means of the SmartLeague programming software. If the BUS does not supply the
peripherals or the devices connected to them, a maximum wire length of 300 meters at
maximum speed (250kbs) can be ensured, regardless of the number of peripherals
connected. At an intermediate speed (125kbs) a single section of 700 metres can be
ensured.
If you wish to increase the length and performance of the BUS, you can connect IB100
isolators.
If the speed of the communication BUS (Baud rate) is low (38.4 or 125 kbps), you can
apply a maximum of 5 isolators in a cascade connection.
If the speed of the communication BUS (Baud rate) is high (250 or 2 kbps), you can
apply a maximum of 2 isolators in a cascade connection.
You can connect up to 15 isolators in all.
ATTENTION!
It is extremely important to evaluate correctly the number of isolators connected in
cascade to the BUS.
