Connect external
alarms
Four external alarm sources can be connected to the External Alarm and Battery
Module via the patch panels. These sources must generate a voltage between 12
and 24VDC. The presence or absence of this voltage will trigger the alarm
depending on how the alarm thresholds have been configured. The module can
also supply +15V to the external alarm sources. The maximum allowed load on
this supply is 100mA.
The External Alarm and Battery Module contains a relay that can be connected to
an external device to indicate an alarm. The relay can be configured to trigger on
any number of internal and external alarms. The maximum current that can be run
through the relay is 100mA.
The external alarm wires are linked to the module via patch panels. These panels
can be released from the module for easier access at installation. The panels can be
used for wires of up to 0.5 mm
2
. To connect a wire, press the yellow lever with a
pen or other pointy item, insert the wire and release the lever.

Cascade connection
of OMUs
If several OMUs are to be cascaded, the links between the OMUs are managed via
the Rack Communication Boards in each unit.
The connections are made via straight Ethernet cables with RJ45 connectors.
These cables can be provided by Axell Wireless in configurations where they are
needed.
