A filter tone alarm is a type of alert system that uses specific sound frequencies to indicate a condition or status, often in industrial or electronic applications. These alarms can be designed to filter out background noise, ensuring that the alert is easily distinguishable. They are commonly used in environments where clear communication of warnings is essential, such as in manufacturing or safety systems. By using distinct tones, they help to quickly grab attention and convey critical information.
