IB-SYSTEM-R
The function of the IB-island8 is independent of its physical position in the rack or the system: the
addresses managed by the board are set during installation dip switch SW2 and can only be
changed by using SW2. A single island is able to collect the signals from 8 devices or 8 barriers
but the numbering is different between the two: for a barrier we mean a complete zone, which
comprises a transmitter and the corresponding receiver. When setting an island to manage 8
barriers it will collect the signals from 8 pairs of transmitter/receiver, which is a total of 16 field
devices. The indications from the pair that comprise the barrier are reported on the same wires;
for example the fault contact for barrier 1 will operate for a fault on the transmitter or the receiver
of barrier 1.
To simplify the installation it is advisable to use an island to manage only devices or only barriers
and to do this the SW1 dip switch must be all ON (devices) or all OFF (barriers). In this situation it
is sufficient to set the correct start address on the island using SW2 as shown in the following
table.

It is advisable, on a system, to set the barrier addresses first and then the individual devices,
which allows the address of a particular sensor on the system to be determined more easily. The
addresses in the previous table are set in sequence from low to high and when an island is set to
manage barriers the address of the next island must jump a position.
For example: suppose we have 16 barriers and 8 single devices, to manage these sensors we
must use 3 IB-island-8, the first two of which manage the barriers and the last manages the
remaining devices. The first island must take the first address, with all the switches of SW2 ON
(first line of the table) and all the switches of SW1 OFF (barriers). The second island also has all
the switches of SW1 OFF but the setting of the address must jump one line of the table (the
previous island manages barriers) and SW2 must be set ON-OFF-ON-ON. The third island must
have all the switches of SW1 ON (devices) and also must jump one line in the address setting
table (the previous island manages barriers) with SW2 set to ON-ON-OFF-ON. If this system has
a new island added to manage new sensors this can occupy the next address without problems
because, as the third island manages devices there is no need to jump a line in the address table
and the next address available in the table is: OFF-ON-OFF-ON (that is convenient to use in
order to manage single sensors and not barriers).
