Ultra Series piezo alarms were engineered with the specific goal of providing a louder, lower-frequency piezo electric buzzer. The sound-cavity of the audible was specially tuned to provide a sound that carries through most ambient-noise environments in a durable component.

Ultra Series alarms are available in six different tones (continuous, beep, warble, siren, whoop and staccato). These alarms are also available as dual function alarms: continuous + beep and continuous + warble.

Ultra Series alarms feature operating voltage ranges of 5-15 Vdc, 6-28 Vdc and 20-30 Vac/dc, and offer low 2KHz center frequency as well as low current consumption.

Available mounting configurations include panel mount through a standard 1-1/8" round hole, as well as PC board mount. UL, and NEMA 4X with optional gasket.

Each alarm is tested three times before shipment.

Ultra Series alarms are rugged and ready for the most challenging environments.

Ultra 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. NEMA type 4X environmental security when used with optional gasket.

These powerful, rugged alarms have the highest output, and are the most water & vibration resistant sound devices of their kind in the world. 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.
