The study found that half of all residential fire fatalities occur during the night when people are sleeping. The Fire Protection and Research Foundation conducted research on various populations, including children, young adults, older adults, alcohol-impaired individuals, and those who are hard of hearing, and discovered that low-frequency tones at 520 Hz are more effective at waking people up than current fire alarm signals. As a result, regulations now require audible devices in sleeping areas to emit different low frequency alarm signals.
The latest edition of UL217 for residential smoke alarm devices made many significant changes to the previously existing standard. One of the main requirements is to prevent false alarms resulting from cooking nuisance.
