Approximately 1 inch in diameter x 0.875 inches in height, this miniature piezoelectric alarm packs an explosive sound output of 103 dB at 2 feet, making it one of the most popular electric buzzers in our product line. 


The M-80 pc mount and PM-80 panel mount piezo electric alarms feature an expanded voltage range of 5-15 Vdc. The M-100 pc mount and PM-100 panel mount have an expanded voltage range as low as 3-6 Vdc.



Each alarm is tested three times before shipment.

These alarms are rugged and ready for the most challenging environments.

M-80 Series alarms are epoxy encapsulated and polarity protected. The solid-state electronics are housed in a 94 V-O flame retardant, heavy-duty thermoplastic enclosure with a stainless steel, corrosion-resistant sound diaphragm to provide maximum environmental security.

These powerful, rugged alarms have the highest output, and are the most water & vibration resistant sound devices of their kind in the world. They are designed to fit in the most compact of spaces, especially where enclosures or other design factors reduce the audibility of the alarm. All Floyd Bell alarms are water resistant.

Best of all, they are 100% made in the U.S.A. For guaranteed delivery and unparalleled quality, you can count on Floyd Bell, the industry leader in audible alarm technology for over 30 years.

The M-80 alarm is available RoHS compliant.
