Control Outputs are configured by defining one or more actions to be triggered on an output event.
The Follow One Alarm function is used to trigger the control output to follow a specific alarm tone in one, any or many specific zones.
This function can be useful in providing visual indication in noisy areas. It differs from the Follow Any Alarm Tone function in that it can follow only one alarm tone, but that this can be active in many zones.

Assigning Follow One Alarm Tone to a Control Output
To assign the function Follow One Alarm Tone to a Control Output:
- In Components view, open Output Actions
- In System, identify the Controller, the Amplifier or the Access Panel to be used, and expand to Device > Control Outputs.
- Drag Follow One Alarm Tone to the Control Output you want to use.
Configuration
Follow an specific alarm tone in any zone
- Drag Follow One Alarm Tone to the desired Control Output.
- Select the desired Alarm in Source.
In this example the Fire Alarm (Offshore) in any zone will trig Control Output 1.
Parameter details
Idle State: Sets the idle state for the output. The options are Normally Open or Normally Closed
Source: The source that will trigger the alarm output. If Source is not specified, it will be ignored when checking whether the conditions for the audio activity triggering are present or not.
Zone: The zones in which the output on an activity is triggered. If Zone is not specified, it will be ignored when checking whether the conditions for the audio activity triggering are present or not. The default is Any zone.
Priority Range: The priority range within which the activity is triggered.
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:
It is common in noisy areas to add flashing lights or beacons which will indicate when there are activity on the PA.
The "follow on alarm tone" function can in this case be used to pulse the flashing light in the same pattern as a specific alarm.
The configuration will then have:
- Source: General alarm
- Destination: "Noisy zone 1", "Noisy zone 2"
- Priority range: 1-40
- Follow alarm tone: checked
With this setup the control output will trigger in the same pattern as the alarm tone. For a general alarm (7 short burst, one long burst) the people in the area will then see the type of alarm which is active.
