ALARM 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, the device will initiate the sending of alarm notification via the alarm type
selected. All the alarms are stored in the device’s log. You have to have in mind that, if there is a
very short fault of the signal, with duration less than the ‘channel trigger time’, the device would
not trigger an alarm.
There are several Alarm Triggers for the following parameters: RF, MPX, Left/Right Audio,
RDS and Pilot levels. There is an option for defining different limits for each of the parameters.
All these values, the ‘trigger time’ and the ‘release time’ have to be assigned separately for each
of the channels.
