IP68 RatingFloyd Bell Products are rated IP68, meaning they still operate when exposed to dust and when SUBMERGED under water!
NEMA 4X RatingWhen used with a gasket (included), our panel-mount products create a NEMA 4X seal. NEMA (the National Electrical Manufacturers Association) is a North American organization that creates standards for the rating of enclosure performance to determine an enclosure's ability to resist external environmental influences. The NEMA Type 4x standard is for enclosures that are intended for indoor or outdoor use primarily to provide a degree of protection against corrosion, windblown dust and rain, splashing water, hose- directed water, and the formation of ice on the enclosure.
RoHS ComplianceFloyd Bell has converted our entire product line to be in compliance with the Restriction of Hazardous Substances Directive adopted by the European Union.

Made in the USAWe are very proud to assemble every one of our products right here in Columbus, Ohio. This allows us quick turn-around time, on-time deliveries, maximum flexibility to meet production scheduling changes and quality, reliable American workmanship. Floyd Bell is the only piezo-alarm manufacturer to assemble all of our alarms in the USA.
Polarity and Surge ProtectionAll Floyd Bell alarms contain special circuitry that protects against power surges. They are rated to provide protection up to 20% over the maximum rated voltage for less than 5 minutes. Our products also contain special circuitry that protects against accidental reverse polarity connection, up to the alarm's maximum operating voltage. Most competing alarms do not contain this feature.
Stainless Steel DiaphragmsAll Floyd Bell alarms use as a premium component: hand-wired stainless steel diaphragms (benders). Floyd Bell chose that material because its alarms are designed have the physical dexterity to withstand a broad range of exacting environmental conditions, including fresh and salt water. Floyd Bell's #304 stainless steel diaphragms, which cost about twice as much as brass diaphragms, provide the most corrosion resistant piezo alarms available in the world.
