Tone Types

Floyd Bell Inc. offers 7 major tone types. We also offer a number of variations within the major tone types, representing a total of thirty-five choices of tone types. They are described below in decreasing order of noticeability. Note that the below-referenced ranges of sound output (i.e. "From 95 db to 109 db") depends upon the amount of voltage applied-the higher the voltage, the higher the sound output. Sample our various tones by clicking on the sound buttons. Indicated in bold type in the text below are the tone types for which we have provided samples.

Siren Tone

Ultra Loud

The siren tone, our most noticeable alarm, sweeps from a low frequency to a high frequency and back again at the rate of three cycles per second. The siren tone alarm is typically used in situations where an important event must be audibly enunciated. The siren tone is well suited to high ambient noise environments where the sweeping tone, coupled with the high sound output (from 95 db to 109 db at two feet), can still be heard. Siren tones are often used as overflow detectors in petroleum tanks. The siren tone is available in 3 voltage ranges: 5-15 VDC, 6-28 VDC, and 20-30 VAC / VDC.

Staccato Tone

Ultra Loud

The staccato tone rapidly sweeps from a low tone to a high tone at the rate of eight times per second. The staccato tone alarm is typically used in situations where an important event must be audibly enunciated. The staccato tone is well suited to high ambient noise environments where the sweeping tone, coupled with the high sound output (from 95 db to 109 db at two feet), can still be heard. Staccato tones are often used as overflow detectors in petroleum tanks. The staccato tone is available in 3 voltage ranges: 5-15 VDC, 6-28 VDC, and 20-30 VAC / VDC.

Whoop Tone

Ultra Loud

The whoop tone sweeps from a low tone to a high tone at the rate of twice per second. The siren tone alarm is typically used in situations where an important event must be audibly enunciated. The siren tone is well suited to high ambient noise environments where the sweeping tone, coupled with the high sound output (from 95 db to 109 db at two feet), can still be heard. Siren tones are often used as overflow detectors in petroleum tanks. The siren tone is available in 3 voltage ranges: 5-15 VDC, 6-28 VDC, and 20-30 VAC / VDC.

The warble tone alternates between a low frequency sound and a high frequency sound. Ultra loud models are available in 2 warble cadences, slow (1 pulse per second) and fast (3 pulses per second). Medium loud are available in 3 warble cadences, 2, 10 and 15 cycles per second. The warble tone alarm is typically used in situations where an important event must be audibly enunciated. The warble tone is well suited to high ambient noise environments where the sweeping tone, coupled with the high sound output (from 95 db to 109 db at two feet), can still be heard. Warble tones are often found in water treatment plants and aeration septic systems. Ultra loud warble tones are available in 3 voltage ranges: 5-15 VDC, 6-28 VDC, and 20-30 VAC / VDC. Medium loud warble tones with 2 or 10 cycles per second are available in 4 voltage ranges: 6-16 VDC, 5-30 VDC, 9-48 VDC, and 5-30 VAC/DC, and with 15 cycles per second, in 3 voltage ranges: 30-120 VAC, 130-220 VAC and 15-36 VAC.

Continuous Tone

Medium Loud
Extra Loud
Ultra Loud

The continuous tone emits a constant sound for as long as power is applied. The continuous tone is generally used as an alert, alarm or trouble signal. Representative applications include golf cart back-up alarms, oil pressure alerts, and high temperature alerts. The continuous tone alarms are available in 3 sound levels: medium continuous tone (68 db to 95 db), extra loud continuous tone (82 db to103 db), and ultra loud continuous tone (96 db to 108 db). All sound levels are measured at 2 feet (61 cm).

In addition, we have a miniature continuous tone, high output product line, the M-80 series (M-80 and PM-80 / M-10 and PM-100), that produces sound levels of between 92 db and 102 db. The M-80 series is used in various marine applications, such as fluid level and oil pressure detection.

The medium continuous tone alarms have eight voltage ranges: 1-16 VDC, 1-30 VDC, 5-16 VDC, 5-30 VDC, 9-48 VDC, 5-30 VAC / VDC, 30-120 VAC / VDC, 130-220 VAC. The extra loud continuous tone alarms have 4 voltage ranges: 2-12 VDC, 3-30 VDC, 120 VAC, 220 VAC. The ultra continuous tone has 3 voltage ranges: 5-15 VDC, 6-28 VDC, and 20-30 VAC / VDC. The miniature continuous tone line has two voltage ranges: the M-80 / PM-80 operates at 5-15 VDC, and the M-100/PM-100 operates at 3-6 VDC.

Beep Tone

The beep tone is a repeating series of off-and-on sound pulses with an approximate duty cycle of 50%. Most beep tone models are available in four cadences: slow beep (one pulse per second), medium beep (two pulses per second), fast beep (three pulses per second), and ultra fast beep (six pulses per second). The beep tone is sharper and more discernable than the chime tone. It is commonly used in snowmobiles to alert of reverse movement and in various farm equipment warning systems. The beep tone alarms come in 3 loudness levels: medium (85 db to 95 db), extra loud (90 db to 104 db), and ultra loud (97 db to 109 db), all of which are measured at 2 feet (61 cm). The medium beep tone unit has six voltage ranges: 5-16 VDC, 5-30 VDC, 9-48 VDC, 5-30 VAC / VDC, 30-120 VAC / VDC, 130-220 VAC. The extra loud beep tone has 5 voltage ranges: 2-12 VDC, 3-30 VDC, 5-12 VDC, 30-120 VAC, and 130-220 VAC. The ultra loud beep tone has 3 voltage ranges: 5 VDC - 15 VDC, 6-28 VDC, 20 VDC / VAC.

Single Shot

The chime tone, our least noticeable alarm, decays from loud to soft. We offer three versions of chime tones: fast (2 chimes per second), medium (1 chime per second), and single (chimes only once). The chime tone is used in situations where a more pleasant tone is required such as in elevators, offices, medical equipment, and vehicle compartments. The Chime tone produces sound output of between 70 db and 90 db The chime tone is available in three voltage ranges: 5-25 VDC, 120 VAC, and 220 VAC.

In addition to all of the single function alarms described above, Floyd Bell offers dual function alarms that give the customer the option of an alarm that is capable of emitting two different tone types. Dual function alarms are available that emit both beep and continuous tones, and that emit both warble and continuous tones. The customer controls the choice of tones and the triggering events that activate and alternate between the dual tones. Each dual function alarm is available in both ultra loud and medium loud. Sound samples at left illustrate the following dual function combinations: medium beep and continuous tones at 2 pulses per second; ultra loud beep and continuous tones at 1 pulse per second; medium warble and continuous tones at 2 pulses per second; and ultra loud warble and continuous tones at 3 pulses per second.

Announcer™ Series

Caution
Warning
Equipment Malfunction
Vehicle in
Motion

Sometimes a "beep" or "whoop" doesn't convey enough information to an operator of a machine. Floyd Bell Inc., manufacturer of popular Audiolarm® piezo electric buzzers, has solved this problem with a new line of high-quality digital audio alarms.

New Announcer™ Series alarms from Floyd Bell play a pre-recorded audio message up to ten seconds at 95 dB. The same size as a standard piezo alarm, they provide the ability to replace an ambiguous beep with voice instructions or warnings.

You have the ability to choose from standard warning messages ("Warning!"), send us your own file, or have Floyd Bell provide the production of the message at our in-house production studio! Announcer™ Series alarms come standard with quick connect terminals, a special grill designed for maximum acoustic output, and voltage range to fit your application.
