An audible alarm works by detecting a specific condition or signal, such as smoke, motion, or unauthorized entry, and then generating a loud sound. This sound serves to alert individuals in the vicinity of potential danger, prompting them to take appropriate action. The alarm system consists of sensors that are connected to a control unit, which processes the signals and activates the alarm. Most alarms are designed to generate sound levels significantly higher than the typical environmental noise, ensuring they capture attention immediately.
