Alarms, Buzzers, and SirensAlarms, buzzers, and sirens are devices that produce a loud, attention-grabbing sound to alert or warn people of a situation. They are commonly used in a variety of applications, including security systems, fire alarms, and emergency vehicles. Alarms, buzzers, and sirens may be standalone devices or may be integrated into larger systems, such as alarm panels, siren controllers, or speaker systems. They may produce a continuous or intermittent sound, and may have features such as volume control, tone control, or synchronization with other devices. Alarms, buzzers, and sirens are available in many different sizes and styles, depending on the specific application. Some may be designed for indoor or outdoor use, while others may be waterproof or shock-resistant.
