Alarm
If required, connect an external status monitoring device to the
ALARM connector.
A 9-way, D-type male connector provides an alarm relay interface
which can be used to send a signal to remote equipment.
When there are no active alarms or fails, the relays are energised. They are de-energised
when there is an active alarm or active fail. Thus, a loss of power will be signalled as an alarm
and fail.
