    E-mail: office@devabroadcast.com ,Web: www.devabroadcast.com ALARM / WARNING TRIGGERS DEFINED After collecting all the data the DB44 DSP core compares the values measured with the predefined by the user threshold levels for all the channels monitored. In case that any parameter is out of its limits or a potential problem has been detected, the device will initiate the sending of alarm/warning notification via the alarm type selected.

For example: Let’s suppose that the Alarm/Warning Trigger is in Idle state. Note, that an alarm is not triggered immediately when a parameter level passes over threshold (above High Threshold or under Low Threshold).
