6.4.2 Connection of the alarm inputs

In case of free contact alarm make the connection as
shown in the figure.
The alarm contacts are present on connector (CN1-
CN2).

Fig. 11
The dry contact alarm can be NO (normally open) or
NC (normally closed).
All alarms have an approximate reach of 200m, which
can be obtained using an unshielded cable with a
minimum section of 0.25mm² (24 AWG).

6.4.3 Relay connection

Relays can be used for low working
voltages only (up to 30Vac or 60Vdc) and
with a maximum current of 1A. Use cables
with a section suitable for the load to be
controlled and use cables with a minimum
section of 0.25mm² (24 AWG) and maximum
section of 1.5mm² (16 AWG).
The relay clamps are located in the relative connector:
Relays and alarms (6.4.1 Description of the secondary
board, page 15).
Relays do not have polarity and therefore both
terminals A or B of the same relay can be used, for
alternating or continuous current voltages.
