Silence connection

A write connection. If alarms use the audio signal, assign a digital tag to this connection to notify the data source that alarms have been silenced.

When the application starts, this connection has a value of zero. When alarms are silenced, this connection is set to one for the notification hold time and the internal beeper is turned off. At the end of the notification hold time, the connection is reset to zero.

Alarms are silenced under these circumstances:

  • The operator presses the Silence button.
  • An alarm is acknowledged.
  • The Remote Silence connection’s value changes to a new non-zero value.
  • The operator presses the Clear Alarm History button.

If subsequent alarms (that have been set up to sound the internal beeper) are generated, the alarms sound the beeper regardless of the Silence connection value or notification hold time status.

While the notification hold time is in effect, new alarms cannot be silenced.
