Speaker cluster distributing Alarm Tones

This article explains how the Alarm Generator in Exigo can be used.

In Exigo, there are already some predefined Alarm Tones . But it is also possible to make custom Alarm Tones or customize the predefined alarms.

The Alarm Generator is located on the PSC (Primary System Controller) and the alarm tones are generated by the system controller.


Configuration

The Alarm Generator is configured using the EMT.

In the device tree:

  • Select System > Alarms
  • Select the Alarm you want to edit
Alarm Generator in EMT


  • When you have finished editing, click Done

Add or Delete Alarms

It is also possible to create new Alarms that can be configured from scratch.

  • In the upper right corner click the Add icon to create a new alarm.
Add or Delete Alarms


  • To delete an alarm, click the Recycle Bin next to the Add icon

Alarm Generator Script

The Alarm Generator is based on simple script programming.

The programming language is based on Lua. For more information see this article.

Alarm Generator Example

Script Example:

local freq = 1000
    for i = 1,7 do
    call_state ('alarm_tone', 'on')  
    sine( 1, freq )
    call_state ('alarm_tone', 'off') 	
    silence(1)
End
call_state ('alarm_tone', 'on')
sine( 4, freq ) 
call_state ('alarm_tone', 'off') 
silence(1)

Script Explanation:

  • local freq is a variable
  • for <> end is a for loop which runs for i times
  • silence(x seconds) is silence for x seconds long
  • call_state is used for control outputs to see when alarm is off with follow alarm
  • sine(x seconds, freq) is a sine tone lasting x seconds long with frequency

This alarm is thus:

Seven repetitions of series with:

Alarm tone of 1 kHz for one second
Alarm off for 1 second

Then alarm tone of 1kHz for 4 seconds

Then silence for 1 second before restarting sequence

This script example is for General Alarm.
