Fault Indication

Best practice - Create a table with relevant information

The Fault Indication function is used to trigger the control output on faults or warnings in the system.

This can be used to send a signal to external systems (like BMG (Building Management Systems)). It can also be used to give visual notifications when there is fault in the system.

Assigning Fault Indication to a Control Output

To assign the function Fault Indication to an Control Output:

1. In Components view, open Output Actions
2. In System, identify the Controller, the Amplifier or the Access Panel to be used, and expand to Device > Control Outputs.
3. Drag Fault Indication to the Control Output you want to use.

Assigning Fault Indication function to a Control Output

Configuration

Visual indication of a fault in the system

The output is used to give a visual indication of a an error in Zone 4.

1. Drag Fault Indication to the desired Control Output.
2. Select Zones in Filter Mode. This will give you the option to select zones.
3. Select Zone 4 in Affected Zones.
4. In Severity (level) select Error.

Visual indication of errors in Zone 4

In this example an error in Zone 4 will trig Control Output 1.

Parameter details

Idle State: Sets the idle state for the output. The options are Normally Open or Normally Closed

Delay Activation: Delays control output activation for the stipulated number of seconds when triggered.

Reporting System: The system, i.e. System A, System B or System A and B, from which faults will be received (only available in A-B System projects).

Subscribe To: Options are Faults or Warnings.

Filter Parameters:

Affected Devices: Trigger on faults that affect selected devices.

Affected Zones: Trigger on faults that affect selected zones.

Affected Lines: Trigger on faults that affect selected audio lines.

Severity: Trigger on faults at selected levels.

Fault State: Trigger on faults in selected state.

System Message: Trigger on faults that have selected messages.

Filter Script

Filter Script field will show the actual script which will be used to determine if output should be triggered or not. This script is constructed based on selection of filter parameters.

Advanced Options:

Limit High Not OK: When the Control Output is cleared, and feedback voltage is at or above this value, the output is considered fed with alien voltage.

Limit Low OK: When the Control Output is set, and feedback voltage is above this value, the output is considered active OK.

Example of use:

Case 1: System messages

The system should trigger a control output connected to another system if any device is missing. Fault indication will in this example be configured:
Filter mode: System messages
System message: Missing device

Case 2: System messages

The system should trigger a control output connected to another system if there is a fault which affect a specific zone. Fault indication will in this example be configured:
Filter mode: Zones
Affected Zones:Zone 2

Case 3: Custom fault

The system should trigger a control output connected to another system if one of the external faults are triggerd . Fault indication will in this example be configured:
Filter mode: System messages
System message: External fault
This will trigger on any external fault in the syste. If more granularity is required then filter mode=devices can be used to only trigger on external faults from a specific device.
