The AA37 series are dual channel Alerting Systems that provide two to three level alerting. All outputs are fully isolated to allow installation in dual audio controller systems. Trigger inputs can be active low or active high dependent on the model, allowing easy interface to common aircraft systems. The tone and rate of the alerts are adjustable to allow tailoring of the tones to ensure they do not interfere with existing airframe warning functions.
