All disconnected wires must be electrically
isolated.
All alarms have an approximate reach of 200m,
which can be obtained using a shielded cable with a
minimum section of 0.14mm² (30AWG).
7.1.7.1 Connecting an alarm with dry contact
For a dry contact alarm (alarms AL1, AL2, AL3, AL4,
AL5), implement the connection as shown in the
figure.
AL1 COM
Dry contact

The dry contact alarm can be NO (normally open) or
NC (normally closed).
For further information refer to the relative chapter (
9.1.8.1 Alarms Menu, page 44).
7.1.7.2 Relay connection
The relays are usable with the specifications
described below. Working voltage: up
to 30Vac or 60Vdc. Current: 1A max. Use
suitable cable sections with the following
characteristics: from 0.25mm² (24AWG) up
to 1.5mm² (16AWG).
Due to the absence of polarity, both terminals of
the same relay can be used equally with either
alternating or continuous current.
For further information refer to the relative chapter (
9.1.8.1 Alarms Menu, page 44).
