From Mallory Sonalert Products, Inc.
From smoke detectors to automobiles,
audible alarms (also known to be called
buzzers) have become a part of our
everyday life. Some of the uses of these
alarms are innocuous such as in a
microwave oven. However, in some
applications such as in a smoke detector
or medical equipment, a person's life
may depend upon the audible warning
sound. In all cases, the equipment
designer should consider the desired
characteristics of the audible alarm at the
initial design planning phase to obtain
satisfactory performance and avoid
costly redesign. The first characteristic
for a designer to consider is the type of
sound such as a continuous, intermittent,
or specialty sound. Other critical criteria
include sound level, frequency, current
draw, quality, mounting configuration,
cost, and availability.
