PIEZO ALARMS ENCASED EXTERNAL DRIVE (no internal circuitry) PKM Series The piezo alarms described on this page have no “feedback” tab and are particularly suited for the generation of both single tones and the unusual sound effects that are possible with specifically designed driving circuits.
These sounds may include musical melodies, insect sounds, etc.
All mechanical and electrical components are designed to be compatible with most standard PC board assembly and wave soldering techniques.
