==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.<br>

The various IP-ARIO PA faults and states are reported as sub events on the [[Faulty_Station_Line_(Event_Type) | 13-Faulty Station Line]].<br>
When a fault state is reported OFF from IP-ARIO, the fault state in AlphaCom will stay active until acknowledged and cleared by the user. <br>

Subevent 10-18 will only be reported once. The error will stay active in the system, even if the error has been removed, until one have performed an [[PA_Failure_State_System#Fault_ACK.2FCLEAR_on_DAK_keys|ACK/CLEAR sequence]].

A NVRAM structure is used for additional configurable elements. <br>
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. ([[IP-ARIO#Default_Grouping_of_fault_state_on_CRM_DAK | 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. <br>

== PA fault Example Configuration ==

=== Fault Handeling on a CRM with DAK pannels ===

The status of faults of one IP-ARIO are grouped to one CRM DAK block of 3 * 4 DAK keys. <br>
[[IP-ARIO#Default_Grouping_of_fault_state_on_CRM_DAK | DAK block]]

The block number used for each IP-ARIO is configured in AlphaPro->Station-> "used defined parameter" (%EXP). <br>
Block number 1 to 8.

Example system:
*Three IP-ARIO in UDP group 1, DAK block 1,2 and 3 programmed in EXP.
*Two CRM with DAK modules in station group 2 and UDP 2.
*RCO 1 used for fault indication of fault state in UDP group 1 (ON or OFF)

===Event for fault indication and fault mail===
The following event will do: (in this order)
*Set fault indicators on CRM DAK panels in CRM group 2 in the DAK block position.
*Send Mail and Cancel Mail to CRM group 2, with related fault priority.
*Set Zone fault indicator on CRM DAK blinking/steady/off
*Set fault indicator led on IP-ARIO
*Set global fault indicator (RCO) related to fault in UDP group 1 (Do we need blinking?)
*Control ACK and CLEAR status led for the related DAK Block leds.
