Connections
The
three
panels
of
the family have the same connections. The main differences in these panels is the number of
the
available
zone
s
and the number of
the
relays
zones. The common outputs, the maximum consumption and the
operation procedures are identical for all the panels.
Connecting detectors and break-glass call points to zones.
By default each zone terminal block has a preinstalled terminal resistor (
8
Κ
2
). This resistor must be removed and
installed on the last device of the zone or is left connected on the zone terminals if the zone is not used. The connections
to all the zone
s
are identical. What is shown in figures 2, 3 and 4 for zone 1 is valid for all the zones.
The total number of connected devices per zone is 20.
All cable zones must be insulated, to earth ground, to meet EMC requirements.
The cable length for each zone must not exceed the 1.5 kilometres with a cross section cable of 1.5mm².

detectors. A remote indication LED BS-572 is connected to one of the detectors.

Connecting
these detectors must also be connected to the terminals
24V_M
in order to be supplied with power.
