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

2.4.5 Modem Connections
Connect the
modem
If the OMU is equipped with a wireless modem an antenna for the modem
is necessary. This can be realized either via a separate antenna or via a
coupler on the RF in/out port in the OMU.
The coupler can only be used if the OMU runs on the same frequencies as
the modem and the Rx/Tx is combined (there is a duplex filter).
The separate antenna is plugged in to the Antenna connector on the far
right end of the OMU. The connector is SMA.
If the OMU is equipped with a PSTN modem the connector is placed in the
Modem Unit. The connector is RJ11
The Ethernet connection is placed on the Control Module. The connector is
RJ45.
