Configuring Alarm Sounds

Use the Alarm Sounds dialog box to configure a sound file (a WAV file) that will play when an unacknowledged alarm displayed in the alarm notifier falls within the configured alarm priority range.

Alarm sounds will still play in a screen, even if the alarm notifier is disabled. Alarm sounds can be disabled via a command-line parameter for the instance of Canvas View or Canvas View Lite.

These settings are saved in XML format as part of the global settings file (.gsf) for your Canvas application and applied to all instances of Canvas.

Configure alarm sounds

When you have an alarm notifier open on any Canvas screen, it can be configured to play a WAV file to notify you of any unacknowledged alarms. You can use any of the standard Microsoft Windows sounds or record your own WAV files. You can also configure a delay between sounds.

1. In the Backstage view, go to Alarm Notifier, and click Alarm sounds to open the Alarm Sounds dialog box.

1. Lowest Priority — Type a value to represent the lower end of the priority range. If you are using the CygNet Standard Point Scheme, the total valid range is 0 to 99, with 0 being the lowest and 99 the highest.
2. Priority Range — This read-only column will automatically update to display the range based on the low value you entered, up to the bottom of the next configured range. For example, 0-24, 25-49, 50-74, 75-99 to represent four ranges from 0 to 99.
3. Sound —

1. Default sound — Use the default sound provided in Canvas.

4. Delay (s) — Type a value in seconds to delay the playing of the sound.
5. Click (Delete row) to remove a selected row as necessary.
