Since 1966, Mallory Sonalert Products, Inc. has been a manufacturer of high quality standard and custom audible alarms. Manufactured in the USA, Mallory Sonalert alarms feature solid-state electronics, polarity protection, rugged and safe case materials, corrosion resistant brass solid diaphragms, as well as water and vibration resistance.

Mallory produces an audible tone by internally creating an oscillating Oscillatingsignal which drives a piezo ceramic transducer mounted in a sound chamber. Various types of continuous and intermittent tones are available.

Mallory Sonalert can be actuated by AC and DC power signals and has several mounting configurations and terminations available.

MCP parts are used in a wide variety of industrial, medical and consumer applications. Alarms in the MCP series utilize efficient piezoelectric technology, which means that customers can expect a compact alarm with a wide voltage range, low current levels, and loud sound levels.

The MCP series alarms have a constant tone, but with low frequencies that are typically only available in alarms with much larger sizes. These alarms feature extended temperature ratings that will hold up under the most extreme environments while offering an overall cost effective design.

Because the operation of the Sonalert audible device is dependent upon the circuit in which it is used, it is advisable to thoroughly test the selected device in the specific circuit and application to assure mechanical and electrical compatibility and verify system performance.
