Smoke alarms work by detecting small particles of combustion (smoke) that must travel into the smoke alarm’s sensing chamber before alarming. If those particles cannot or do not find their way into the sensing chamber, it will not alarm.
Eye Detekt, on the other hand, constantly monitors for the presence of flame in your home and works by detecting a narrow band of ultraviolet light produced by the flame. The moment the flame is seen, you’re notified. It’s that simple!
