Alarm Sounds by area

I have just added 2 new workstations to an existing DeltaV network.  They will be used primarily for the part of the process in one area.  Since I wanted to maintain flexibility on how the workstations are used, I limited access by user privileges.  One operator account can access the old part of the plant while a new operator account can access the new part of the plant.  While the workstations are getting the proper alarms for their areas, I would like the old and new parts of the plant to have different alarm sounds since they are in the same control room.  I see that DeltaV has 2 alarm sound groups for this very purpose.  How can I specify that the alarms from one area use the second set of sounds while everything else uses the first set

  Alarm Sounds can't be done by areas per say, alarm sounds 'can' be by workstation (with some manual intervention).  You can only pick one sound currently in the database for alarm priority sound (nothing about area or workstation), so you have to pick the sound you want and then go to the machines and rename the sound files so that the sound you want to hear the station is named the same as the configuration of the alarm priority.

  For example: You configured WSA-High 2010HCS.wav for Critical Alarm

  1. Go to workstation(s) DVData\sound folder and rename the configured file (WSA-High 2010HCS.wav) to be WSB-High 2010HCSa.wav
  2. Rename WSB-High 2010HCS.wav to be what the selected file above was (WSA-High2010HCS.wav)
  3. Rename WSB-High 2010HCSa.wav to be WSB-High 2010HCS.wav to complete the process.
  4. This workstation will now have different sound for Critical priority alarms than other workstation(s)
  5. Follow the same process for sounds on other workstations to get desired results.

  Note: this process is using same names of the files that already exist but you could create a new name wave and select this for alarm priority but you will have to ensure this named file is on all machines manually as the sound folder isn't handled by Yellowpages.

  So back to initial request - the only way to get exactly what I think you want is to follow process above for workstations supporting 'new' areas, only have 'old' area(s) assigned to 'old' workstation(s) alarms and events, 'new' area(s) only to the 'new' workstation(s) alarms and events.

  Hopefully this was clear enough :D

  There is another way to achieve this but it requires a bit more work.
  
  The alarm sound is a property of the alarm priority. To have different alarm sounds create a new set of alarm priorities for Critical, Warning and Advisory alarms using some of the 'spare' alarm priority values eg 14, 10 and 6. These will have to be named something slighly different to the standard priorities eg 14 could be "CRITICAL_", 10 could be "WARNING_" etc or you might include the plant area identification eg CRITICAL-1 etc. Assign the desired alarm sounds to the new priroities.
  
  Then change the alarm priorities for all the alarms in all the modules in the new part of the plant so that they use the new set of priorities. This is the time-consuming bit, but can be done relatively easily using alarm management and bulk edit export and import.
  
  Apart from the work in changing the priorities, the only disadvantage is that the alarm priority name is eg WARNING_ rather than WARNING. The colours on alarm banners etc should still be OK as these are based on a global colour table that defines priorities 15-12 as the critical colour 11-8 as warning colour etc.

  Thank you for the quick response. That would be quite workable.
