PA Failure State System
From Zenitel Wiki
==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 13-Faulty Station Line.
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.
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 ACK/CLEAR sequence.
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.

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.
DAK block
The block number used for each IP-ARIO is configured in AlphaPro->Station-> "used defined parameter" (%EXP).
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.
