The device can communicate between buses based on SCS technology, even
if they are dedicated to different functions. Whatever the mode of use of
the interface remember that the two buses connected to it for all purposes
form two systems and, as such, are subject to all the dimensioning and
installation rules laid down.
Address configuration (configurators I1 I2 I3 I4)
Housings I1, I2, I3 and I4 are used to identify the interface inside the system
uniquely.
With actuators and controls this function is performed by the configurators
in housings A (room) and PL (light point). In both cases configuring the
device means giving it an address which identifies it. The interface address
must be different from any other address on the two buses connected to it.
Depending on the mode of use the interface may have an address defined
with only two configurators, I3 and I4, leaving the housings for I1 and I2
empty, or with all four:
- Only I3 and I4; when the interface is used in the physical expansion,
logical expansion, burglar-alarm/automation interface
- I1, I2, I3 and I4; when the interface is used in the public riser mode.
Operating mode configuration (MOD configurator)
The following five modes are available:
1 Physical expansion (configurator MOD=1):
can increase the total bus length or exceed the absorption limit of 1200
mA for the individual power supply.
As for the installation limitations, please refer to the chapter “General
rules for installation”.
2 Logical expansion (configurator MOD=2):
can increase the number of devices of a system, which is 81 (max 9 rooms
with 9 light points each).
As for the installation limitations, please refer to the chapter “General
rules for installation”.
3 Public riser (configurator MOD=3):
can interface the digital door entry or video door entry systems with the
other buses of the burglar-alarm or automation systems.
4 Burglar-alarm/automation interface (configurator MOD=4):
allows the automation and burglar-alarm systems to communicate.
5 Galvanic separation (configurator MOD = no configurator required):
can interface different functions (ex.: Sound system with Automation).
