Alarm Function
This function requires the controller option. The user
can assign triggers for the preferred Major / Minor
and No Alarm conditions using the controller and
supplied software.
The alarm connector provides GPO contacts for 2
alarm levels and a GPI input for future use. This
allows for the connection of an external monitoring
system. Alarm conditions are triggered by the
optional control system and will vary depending on
the configuration of the system and user

For critical failures in the rack a contact can be

Some examples of “major” failures in the rack are:
• Loss of Power
