Alarms
As the SMART System is recording and analyzing, it can trigger alarms when the characteristics of the bat call meet certain parameters. Raised alarms can be sent to a control system in order to shut down or slow a turbine.
A single SMART System can have eight pairs of alarms. In each pair, one alarm operates on individual echolocation pulses, and the other operates on passes, sequences of pulses recorded as a bat flies past the microphone. For each pair of alarms, you can define matching call characteristics using Boolean logic to determine what kinds of sounds will satisfy the alarms. This flexible logic allows you to avoid false alarms from non-bat sound sources and define unique alarm behavior for different bat species or different microphones depending on their placement.
Each pair of alarms shares a set of call characteristics but has independent settings for the number of matching pulses or passes in a given period required to raise the alarm. You may decide to use one or both alarms in each pair.
