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.

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

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.

Owner:        UDP 1
Event Type    13-Faulty station line

Fault ACK/CLEAR on DAK keys

One common ACK event for all CRM stations in UDP 2 for each IP-ARIO.

Owner:        UDP 2
Event Type    30-DAK AS RCI
Sub Event     CRM DAK key used for Ack
When Change   ON
Action:
$PA_CMD L(IP-ARIO) U01

One common Clear event for all CRM stations in UDP 2 for each IP-ARIO.

Owner:        UDP 2
Event Type    30-DAK AS RCI
Sub Event     CRM DAK key used for Clear
When Change   ON
Action:
$PA_CMD L(IP-ARIO) U02
