Panel-Mount Miniature Buzzers


Style A	Style B	Style C

Style A—Style A are also known as piezo buzzers.

Style B—For Style B the volume increases as voltage increases.

Style C—Style C are also known as piezo buzzers. For Style C the volume increases as voltage increases.

Sound Pattern—Buzzers with a pulse tone alternate on/off to draw greater attention than buzzers with a continuous tone. Buzzers with both a continuous and pulse tone can be wired to trigger two alerts, each corresponding to a different warning. If the continuous and pulse tone are both triggered at the same time, only the continuous tone will sound.
