Slow Warble Tone Piezoelectric Alarm
The Mallory Sonalert produces an audible tone by internally creating an oscillating signal which drives a piezo ceramic transducer mounted in a sound chamber. Various types of continuous and intermittent tones are available. Self driven piezo ceramic transducers are superior to electromagnetic buzzers because they produce no arcing, electrical noise, or mechanical wear during operation. The Mallory Sonalert can be actuated by AC and DC power signals and has several mounting configurations and terminations available.
