2.5.1 The circuits of the detection
The control panel supports exclusively detectors and modules that use a communication system of digital data.
A part from a few models, which need auxiliary power supply 24Vdc, the elements are supplied and communicate
with the control panel through two cables connected to an input module. The detection circuit must be kept the
farthest possible from the other installations and the cables passage, to reduce the risk of external interfaces.
Don’t forget, use shielded and twisted cable, to reduce the interferences. The section will depend on the length of
loop.
WARNING
Installations with cable length superior to 2Km are
not advised
, because the capacity and the induction of cable
can start to interfere with data communication from this length onward.

N.B.: test lines as provided in “LINE CABLE TEST PROCEDURE BEFORE LOOP CONNECTION” before
connecting loop to the control panel.
The system
is preset for the installation up to four circuits of detection (1, 2, 3 and 4 loops) with a maximum
capacity of 508 points (detectors, buttons, Input/output modules or isolator) with the possibility to install up to 120
points (exclude isolator) in a single loop.
As reported in the instructions of the single products, the detectors, buttons and Input/output modules must be
addressed.
The descriptions of the different procedures of programming – addressing (single point; self-increment; through
series number) will be dealt with in
PART 4 of this manual.
