PIEZO ALARMS
ENCASED EXTERNAL DRIVE (no internal circuitry)
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.

PIEZO ALARMS
ENCASED PIEZO ALARMS
SELF DRIVE (no internal circuitry)
As the use of microprocessors in consumer
products has become increasingly popular,
so too has the use of piezo alarms as the
accepted means of audio alarm generation.
Their ability to be driven by IC’s, small size,
low cost and high reliability, make them
ideal for such applications.
The units shown on this page are equipped
with a feedback tab for use with self-
oscillating circuit designs. By utilizing the
feedback, the part’s individual resonant
frequency is found to optimize sound
pressure level.
All mechanical and electrical components
are designed to be compatible with most
standard PC board assembly and wave
soldering techniques.
