All alarms have an approximate reach of 200m, which
can be obtained using an unshielded cable with a
minimum section of 0.25mm² (AWG 30).
• Pass the alarms cables through the entry device.
• Take the J3 removable female connector from the
connectors board and connect the alarm wires to
it.
• Plug the cabled connector to J3 plug.
6.1.10.1 Connecting an alarm with clean
contact (dry contact)
For a clean contact alarm (alarms AL1, AL2, AL3, AL4
and AL5), carry out the following connection:

The clean contact alarm can be NO (normally open)
or NC (normally closed).
For further details on conguring and using the
alarms, refer to the related chapter (9.6.6.1 Alarms
Menu, page49).
6.1.10.2 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. Use cables with a minimum
section of 0.25mm² (AWG 30) and maximum
section of 1.5mm² (AWG 16).
Relays do not have polarity and therefore both
terminals of the same relay can be swapped for
alternating or continuous current voltages.
For further details on conguring and using the
relays, check the relative chapter (9.6.6.1 Alarms
Menu, page49).
• Pass the relays cables through the entry device.
• Take the J3 removable female connector from the
connectors board and connect the relays wires to
it.
• Plug the cabled connector to J3 plug.
