3.5 Alarm Interface

A 13 pin circular DIN connector provides access to 6 alarm inputs that are used to detect metallic
contact closure. For example, they can be used to sense a cabinet door open or temperature sensors.
The priority of these auxiliary alarms may be programmed through the “Alarms>Severity Level
Settings” screen.

There are also relay contact outputs to indicate urgent and non-urgent alarms. This allows the system
to be easily integrated into the alarm systems of other equipment.

3.6 User Interface Modules

The user interface is provided by a plug-in module of which there are six types:

• G.703, with software selectable 75ohm or 120ohm ports

• X.21

• V.35

• G.703 MK II (with 1 + 1 protection switch)

• X.21 MK II (with tail buffer)

• V.35 MK II (with tail buffer)


The existing interface module can be changed out using a pluggable replacement unit. These can be
ordered separately using the part numbers detailed below. For part numbers and order codes see
Appendix B.
