Buzzer, Piezo, Circular, Sonalert, Panel Mount, 64-76 dB(A), Continuous, 41.66mm Mallory #SNP428 The Mallory Sonalert produces an audible tone by internally creating an oscillating signal which drives a piezo ceramic transducer mounted in a sound chamber. Self driven piezo ceramic transducers are superior to electromagnetic buzzers because they produce no arcing, electrical noise, or mechanical wear during operation.
