Audible Signaling

Pfannenberg's horns and sounders are designed to generate tones that are pre-programmed into their circuitry, and the sound is emitted when power is supplied.

Sounders are commonly used for creating evacuation alarms in situations such as fire outbreaks, toxic gas leaks, or chemical spills.

These devices are capable of generating a variety of tones that can be selected by the user. Additionally, some sounders have the ability to produce multiple stages of tones.
