IP-ARIO

PA Failure State System

When used as PA interface some of the IP-ARIO inputs are used for reporting failure state of 1 or 2 amplifiers.

The various IP-ARIO PA faults and states are reported as sub events on the line error event.
When fault state is reported OFF from IP-ARIO the fault state in AMCD will still be active until acknowledge and cleared by the user.

A NVRAM structure is used for additional configurable elements.
Configurable elements are:

• Default description text intended for use in fault mail to PA panels. The text are sent to event handler as %2.nam
• Default placement of status indication in the "DAK block" related to the PA interface. ( DAK block)
• Default priority used for fault mails. (Unique priority make it easy to remove specific fault from mail queues)

Default Grouping of fault state on CRM DAK

The status of faults of one IP-ARIO are grouped to one CRM DAK block of 3 * 4 DAK keys.

Fault Indication On DAK panel
ZONE FAULT	RELAY 1	RELAY 2
IPA DOWN	POWER 1	POWER 2
FAULT ACK	LINE MON 1	LINE MON 2
FAULT CLEAR	XLR DISCON 1	XLR DISCON 2
