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. All the alarms/warnings 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/warning.
There are several Alarm/Warning Triggers for the following parameters: RF, MPX, MPX Power,
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.
