Floyd Bell - Piezo Alarms, Buzzers, and Audio Devices for Durable Industrial Machines - Learn More

Floyd Bell produces the highest quality piezo electric alarms in the world. How do we do it?

We first introduced our piezo based alarms in 1972, and since that time, our research and development department has continuously improved not only the functionality, but also the components, circuitry, manufacturing processes and testing procedures. As a result, our alarms produce a higher decibel output than any alarms of similar size. Our alarms are typically much smaller, resulting in more application versatility for our customers at a reduced cost. In addition, our alarms are more environmentally secure than any other alarms on the market, resulting in a longer, corrosion-free lifespan.

Product Quality

We only use stainless steel piezo elements in our alarms, compared to brass elements used by our competitors. The environmental qualities of stainless steel are well know and far superior to brass. Floyd Bell also utilizes an expensive process joining the contact leads to every piezo element that we use in our alarms. This treatment dramatically increases the reliability, durability and lifespan of the piezo element and thus of every Floyd Bell alarm. Our competitors do not utilize this process to treat their crystals because of the associated cost.

Floyd Bell uses only the finest PCBs (Printed Circuit Boards). Our PCBs are double-sided and fully plated through. This dramatically increases the integrity of every Floyd Bell alarm by increasing the strength of every solder joint and the stability of our alarms in virtually any environment. Our PCBs are solder-masked and the material is UL-94VO rated. All of our PCBs are pre-routed to reduce component stress in de-paneling.

Many of our competitors use a paper-based, single-sided PCB material, which is much less expensive but cannot compare to the engineered quality of our PCBs. All of the PCBs in our alarms are mounted and sealed into the alarm body with an expensive silicone sealant, and then the assembly is potted with a highly engineered 94-VO rated encapsulant.

Every environmental seal between the piezo element and the alarm case is pressure tested before it is ever used in an alarm.
