They are also used as carbon monoxide (CO) detectors
Low-frequency sounders are used as carbon monoxide (CO) detectors in sleeping areas. CO detectors are devices that detect the presence of carbon monoxide gas to prevent carbon monoxide poisoning. Carbon monoxide is a colourless, tasteless, and odourless gas produced by the incomplete combustion of carbon-containing materials, often referred to as the "silent killer".
CO detectors use sensors with a defined, limited lifespan and will not work indefinitely. The lifespan of the sensors typically ranges from two to five years, and newer models are designed to signal when they need to be replaced. These detectors can be battery-operated or AC-powered, with some models offering a battery backup. The battery lifetime of these devices is advertised to last up to 10 years.
The alarm of a CO detector should sound within 60 minutes if the concentration of carbon monoxide rises to 70 PPM, within 10 minutes at 150 PPM, in 4 minutes at 400 PPM, and immediately at 500 PPM or higher. The alarm is designed to not sound too quickly, as brief false alarms may cause users to disable the device, leaving them unprotected.
Low-frequency sounders, such as the Eluxa low-frequency sounder, are designed to awaken individuals effectively in the event of a fire or CO detection. According to a U.S. Fire Administration study, low-frequency tones of 520 Hz were found to be more effective in awakening individuals compared to current fire alarm signals. This frequency can alert people with hearing loss and alcohol-impaired adults.

They are designed to wake up people with hearing loss
Low-frequency sounders are designed to wake up people with hearing loss in the event of a fire or carbon monoxide (CO) detection. They are audible appliances that produce low-frequency alarm signals, typically around 520 Hz, which is significantly lower than the frequency of most fire alarm and smoke alarm tones, which are around 3150 Hz. This higher frequency band is also the one in which most adults experience hearing loss.
Research has shown that a low-frequency 520 Hz signal can effectively awaken and alert people with hearing loss, as well as those who are alcohol-impaired. In fact, low-frequency tones have been found to be more effective in awakening individuals across a range of populations, including children, young adults, older adults, and those with hearing impairments. This is particularly important, given that according to a U.S. Fire Administration study, 50% of residential fire fatalities occur when people are sleeping.
Low-frequency sounders are designed to meet the latest codes and standards for sleeping room accommodations, such as the NFPA 72 for fire signals and NFPA 720 for CO signals. They can be installed in various types of buildings, including motels, hotels, universities, and apartments, and are often required in dormitories, hotel sleeping areas, and other building sleeping areas.
One example of a low-frequency sounder is the Wheelock Exceder LED low-frequency sounder, which meets both fire and CO codes with a single device. When packaged with SAFEPATH audio boosters and Wheelock speakers, Eaton's SAFEPATH SP40S provides a complete solution for sounding 520 Hz low-frequency tones in sleeping rooms.

Low-frequency sounders can be used in sleeping areas in motels, hotels, universities and apartments
Low-frequency sounders are designed to be used in sleeping areas, such as those found in motels, hotels, universities and apartments. They are an effective way to alert individuals to potential dangers, such as fires or carbon monoxide leaks, and can be life-saving in the event of an emergency.
Operating at 520Hz, low-frequency sounders have been found to be more effective at awakening individuals than traditional fire alarm signals, which tend to operate at a higher frequency of 3150Hz. This higher frequency is also the band at which most adults experience hearing loss. By using a lower frequency, these sounders can wake up and alert those with hearing loss and alcohol-impaired adults.
The effectiveness of low-frequency sounders has been demonstrated in a U.S. Fire Administration study, which found that 50% of residential fire fatalities occur when people are sleeping. The same study found that low-frequency tones were more effective at awakening individuals across a range of populations, including children, young adults, older adults, and those with hearing impairments.
Low-frequency sounders can be integrated into existing systems, utilising the same wires as older appliances, making them a simple retrofit to meet new codes for sleeping rooms. For example, Eaton's Exceder LED low-frequency sounders meet both fire and carbon monoxide signalling codes with a single device. Their SAFEPATH system also provides verbal communications, followed by clear, intelligible messages to help direct people to safety.
By installing low-frequency sounders in sleeping areas, organisations can effectively alert residents or guests in the event of an emergency, improving safety and potentially saving lives.

They meet NFPA 72 fire and CO low-frequency sounder codes
Low-frequency sounders are audible appliances that produce a 520 Hz signal, which has been found to be more effective in awakening individuals than traditional high-frequency alarm signals. These low-frequency sounders are designed for sleeping areas and are required by the NFPA 72 fire and CO low-frequency sounder codes.
The NFPA 72: National Fire Alarm and Signaling Code outlines specific requirements for low-frequency sounders in sleeping areas. This code was first introduced in the 2010 version of NFPA 72 and took effect on January 1, 2014. The code requires that all new spaces intended for sleeping, such as hotel rooms, college dorms, apartments, or assisted living facilities, be equipped with low-frequency sounders. Common areas such as hallways and lobbies are exempt from this requirement.
The NFPA 72 code sets specific sound level requirements for low-frequency sounders. They must have a sound level of at least 15 dB above the average ambient sound level, with a maximum sound level of 75 dB. This ensures that the alarm signals are audible and effective in awakening individuals.
To meet the NFPA 72 fire and CO low-frequency sounder codes, organizations can utilize products such as the Eluxa low-frequency sounder line, the Exceder LED3 low-frequency sounder, and the SAFEPATH system. These products enable motels, hotels, universities, and apartments to effectively awaken guests and residents in the event of a fire or CO detection while meeting the latest codes. The Exceder LED3 low-frequency sounder, for example, can provide alarm signals for both fire (T3) and CO (T4) applications in a single device.
By installing low-frequency sounders that meet the NFPA 72 codes, organizations can improve the safety of their sleeping areas and ensure that individuals, including those with hearing loss or other impairments, can be effectively alerted in an emergency. These low-frequency sounders provide a simple retrofit solution, utilizing the same wiring as existing appliances, to enhance the protection of occupants in the event of a fire or CO incident.
